Exemplary Aspects of Articles of Footwear

[0044] Footwear 10 is an exemplary article of athletic footwear that comprises one or more components article made using the methods of the present disclosure. While illustrated as a running shoe, footwear 10 may alternatively be configured for any suitable athletic performance, such as baseball shoes, basketball shoes, soccer/global football shoes, American football shoes, running shoes, cross-trainer shoes, cheerleading shoes, golf shoes, and the like. While an athletic shoe is exemplified in FIG. 1 , it will be readily understood that some of the terminology employed will also apply to other articles of footwear or to other styles of shoe. Footwear 10 includes an upper 12 and a sole component 14 secured to upper 12. Sole component 14 can be secured to upper 12 by adhesive or any other suitable means. As used herein, the sole component 14 can be a monolithic component formed entirely of an article made using the disclosed methods as described herein, or a multi-component assembly formed of a plurality of monolithic components, where at least one of the monolithic components is formed entirely of the article made using the disclosed methods as described herein.

[0045] Footwear 10 has a medial, or inner, side 16 and a lateral, or outer, side 18. For ease of discussion, footwear 10 can be divided into three portions: a forefoot portion 20, a midfoot portion 22, and a heel portion 24. Portions 20, 22, and 24 are not intended to demarcate precise areas of footwear 10. Rather, portions 20, 22, and 24 are intended to represent respective areas of footwear 10 that provide a frame of reference during the following discussion. Unless indicated otherwise, directional terms used herein, such as rearwardly, forwardly, top, bottom, inwardly, downwardly, upwardly, etc., refer to directions relative to footwear 10 itself. Footwear 10 is shown in FIG. 1 in a substantially horizontal orientation, as it would be positioned on a horizontal surface when worn by a wearer. However, it is to be appreciated that footwear 10 need not be limited to such an orientation. Thus, in FIG. 1 , rearwardly is toward heel portion 24 (to the right as seen in FIG. 1 ), forwardly is toward forefoot portion 20 (to the left as seen in FIG. 1), and downwardly is toward the bottom of the page as seen in FIG. 1. Top refers to elements toward the top of the view in FIG. 1 , while bottom refers to elements toward the bottom of the view in FIG. 1. Inwardly is toward the center of footwear 10, and outwardly is toward the outer peripheral edge of footwear 10.

[0046] In some aspects, the component is a sole component, such as a sole component 14 depicted in FIGS. 1-5, that includes article made using the disclosed methods as described herein. In some aspects, the component is an insert such as insert 36 or insert 60 depicted in FIGS. 4-5 that includes article made using the disclosed methods as described herein. The sole components and inserts for sole components can be made partially or entirely of article made using the disclosed methods as described herein. Any portion of a sole component or an insert for a sole component can be made of article made using the disclosed methods as described herein. For example, first portion 26 of the sole component (optionally including the ground engaging lower surface 44, such as the plurality of projections 46 and/or the groove 48 surrounding the projections), the entire insert 36, portions 62 or 64 of insert 60, a separate outsole component, or any combination thereof, can include article made using the disclosed methods as described herein.

[0047] Sole component 14, which is generally disposed between the foot of the wearer and the ground, provides attenuation of ground reaction forces (i.e., imparting cushioning), traction, and may control foot motions, such as pronation. As with conventional articles of footwear, sole component 14 can include an insole (not shown) located within upper 12. . In some aspects, the sole component is an insole or sockliner or is a multi-component assembly including an insole or sockliner, can further include an insole or sockliner located within the upper, where the insole or sockliner is formed entirely or partially of article made using the disclosed methods as described herein. Articles of footwear described herein can include an insole or sockliner formed entirely or partially of article made using the disclosed methods as described herein.

[0048] As can be seen in FIG. 2, sole component 14 consists of a first portion 26 having an upper surface 27 with a recess 28 formed therein. Upper surface 27 is secured to upper 12 with adhesive or other suitable fastening means. A plurality of substantially horizontal ribs 30 is formed on the exterior of first portion 26. In certain aspects, ribs 30 extend from a central portion of forefoot portion 20 on medial side 16 rearwardly along first portion 26, around heel portion 24 and forwardly on lateral side 18 of first portion 26 to a central portion of forefoot portion 20.

[0049] First portion 26 provides the external traction surface of sole component 14. In certain aspects it is to be appreciated that a separate outsole component could be secured to the lower surface of first portion 26. When a separate outsole component is secured to the lower surface of first portion 26, the first portion 26 is a midsole component. In some aspects, the article is a midsole component for an article of footwear.

[0050] In some aspects, the article is an insert. An insert 36 can be received in recess 28. As illustrated in FIG. 2, insert 36 can provide cushioning or resiliency in the sole component. First portion 26 can provide structure and support for insert 36. In such aspects, first portion 26 can be formed of a material of higher density and/or hardness as compared to insert 36 such as, for example, non-foam materials including rubber and thermoplastic polyurethane, as well as foam materials. In certain aspects, insert 36 can be formed of article made using the disclosed methods as described herein.

[0051] Insert 36 has a curved rear surface 38 to mate with curved rear surface 32 of recess 28 and a transverse front surface 40 to mate with transverse front surface 34 of recess 28. An upper surface 42 of insert 36 is in contact with and secured to upper 12 with adhesive or other suitable fastening means. For example, when there is an insert 36, a recess 28 can extend from heel portion 24 to forefoot portion 20.

Permeance

(quantity of gas)/[(area) x (time) x (pressure difference)] = permeance (GTR)/(pressure difference) = cm 3 /m 2 *atm*day (i.e., 24 hours)

Permeability

[(quantity of gas) x (film thickness)][(area) x (time) x (pressure difference)] = permeability [(GTR) x (film thickness)]/(pressure difference) = [(cm 3 )(mil)]/m 2 *atm*day (i.e., 24 hours)

Diffusion at one atmosphere

(quantity of gas)/[(area) x (time)] = GTR = cm 3 /m 2 *day (i.e., 24 hours)

[0002] Additional details are provided regarding the polymeric materials referenced herein for example, the polymers described in reference to the article, components of the article, structures, layers, films, bladders, foams, primer layer, coating, and like the. The polymer can be a thermoplastic polymer. The polymer can be an elastomeric polymer such as a thermoplastic elastomeric polymer. The polymer can be selected from: polyurethanes (including thermoplastic polyurethanes (TPUs) and elastomeric TPUs), polyesters, polyethers, polyamides, vinyl polymers (e.g., copolymers of vinyl alcohol, vinyl esters, ethylene, acrylates, methacrylates, styrene, and so on), polyacrylonitriles, polyphenylene ethers, polycarbonates, polyureas, polystyrenes, co-polymers thereof (including polyester-polyurethanes, polyether- polyurethanes, polycarbonate-polyurethanes, polyether block polyamides (PEBAs), and styrene block copolymers) , and any combination thereof, as described herein. The polymer can include one or more polymers selected from the group consisting of polyesters, polyethers, polyamides, polyurethanes, polyolefins copolymers of each, and combinations thereof.

[0003] The term“polymer” refers to a chemical compound formed of a plurality of repeating structural units referred to as monomers. Polymers often are formed by a polymerization reaction in which the plurality of structural units become covalently bonded together. When the monomer units forming the polymer all have the same chemical structure, the polymer is a homopolymer. When the polymer includes two or more monomer units having different chemical structures, the polymer is a copolymer. One example of a type of copolymer is a terpolymer, which includes three different types of monomer units. The co-polymer can include two or more different monomers randomly distributed in the polymer (e.g., a random co polymer). Alternatively, one or more blocks containing a plurality of a first type of monomer can be bonded to one or more blocks containing a plurality of a second type of monomer, forming a block copolymer. A single monomer unit can include one or more different chemical functional groups.

[0004] Polymers having repeating units which include two or more types of chemical functional groups can be referred to as having two or more segments. For example, a polymer having repeating units of the same chemical structure can be referred to as having repeating segments. Segments are commonly described as being relatively harder or softer based on their chemical structures, and it is common for polymers to include relatively harder segments and relatively softer segments bonded to each other in a single monomeric unit or in different monomeric units. When the polymer includes repeating segments, physical interactions or chemical bonds can be present within the segments or between the segments or both within and between the segments. Examples of segments often referred to as hard segments include segments including a urethane linkage, which can be formed from reacting an isocyanate with a polyol to form a polyurethane. Examples of segments often referred to as soft segments include segments including an alkoxy functional group, such as segments including ether or ester functional groups, and polyester segments. Segments can be referred to on the basis of the name of the functional group present in the segment (e.g., a polyether segment, a polyester segment), as well as based on the name of the chemical structure which was reacted in order to form the segment (e.g. , a polyol-derived segment, an isocyanate-derived segment). When referring to segments of a particular functional group or of a particular chemical structure from which the segment was derived, it is understood that the polymer can contain up to 10 mole percent of segments of other functional groups or derived from other chemical structures. For example, as used herein, a polyether segment is understood to include up to 10 mole percent of non-polyether segments.

[0005] In aspects, exemplary thermoplastic polymers include homo-polymers and co polymers. In certain aspects, the thermoplastic polymer can be a random co-polymer. In one aspect, the thermoplastic polymer can be a block co-polymer. The term“polymer” refers to a polymerized molecule having one or more monomer species, and includes homopolymers and copolymers. The term "copolymer" refers to a polymer having two or more monomer species, and includes terpolymers (i.e., copolymers having three monomer species). For example, the thermoplastic polymer can be a block co-polymer having repeating blocks of polymeric units of the same chemical structure (segments) which are relatively harder (hard segments), and repeating blocks of polymeric segments which are relatively softer (soft segments). In various aspects, in block co-polymers, including block co-polymers having repeating hard segments and soft segments, physical crosslinks can be present within the blocks or between the blocks or both within and between the blocks. Particular examples of hard segments include isocyanate segments and polyamide segments. Particular examples of soft segments include polyether segments and polyester segments. As used herein, the polymeric segment can be referred to as being a particular type of polymeric segment such as, for example, an isocyanate segment, a polyamide segment, a polyether segment, a polyester segment, and the like. It is understood that the chemical structure of the segment is derived from the described chemical structure. For example, an isocyanate segment is a polymerized unit including an isocyanate functional group. When referring to a block of polymeric segments of a particular chemical structure, the block can contain up to 10 mol % of segments of other chemical structures. For example, as used herein, a polyether segment is understood to include up to 10 mol % of non-polyether segments.

[0006] In general, a thermoplastic polymer softens or melts when heated and returns to a solid state when cooled. The thermoplastic polymer transitions from a solid state to a softened state when its temperature is increased to a temperature at or above its softening temperature, and a liquid state when its temperature is increased to a temperature at or above its melting temperature. When sufficiently cooled, the thermoplastic polymertransitions from the softened or liquid state to the solid state. As such, the thermoplastic polymer may be softened or melted, molded, cooled, re-softened or re-melted, re-molded, and cooled again through multiple cycles. For amorphous thermoplastic polymers, the solid state is understood to be the “rubbery” state above the glass transition temperature of the polymer. The thermoplastic polymer can have a melting temperature from about 90 degrees C to about 190 degrees C when determined in accordance with ASTM D3418-97 as described herein below, and includes all subranges therein in increments of 1 degree. The thermoplastic polymer can have a melting temperature from about 93 degrees C to about 99 degrees C when determined in accordance with ASTM D3418-97 as described herein below. The thermoplastic polymer can have a melting temperature from about 1 12 degrees C to about 1 18 degrees C when determined in accordance with ASTM D3418-97 as described herein below.

[0007] The glass transition temperature is the temperature at which an amorphous polymer transitions from a relatively brittle“glassy” state to a relatively more flexible“rubbery” state. The thermoplastic polymer can have a glass transition temperature from about -20 degrees C to about 30 degrees C when determined in accordance with ASTM D3418-97 as described herein below. The thermoplastic polymer can have a glass transition temperature (from about -13 degree C to about -7 degrees C when determined in accordance with ASTM D3418-97 as described herein below. The thermoplastic polymer can have a glass transition temperature from about 17 degrees C to about 23 degrees C when determined in accordance with ASTM D3418-97 as described herein below.

[0008] The thermoplastic polymer can have a melt flow index from about 10 to about 30 cubic centimeters per 10 minutes (cm 3 /10 min) when tested in accordance with ASTM D1238- 13 as described herein below at 160 degrees C using a weight of 2.16 kilograms (kg). The thermoplastic polymer can have a melt flow index from about 22 cm 3 /10 min to about 28 cm 3 /10 min when tested in accordance with ASTM D1238-13 as described herein below at 160 degrees C using a weight of 2.16 kg.

[0009] The thermoplastic polymer can have a cold Ross flex test result of about 120,000 to about 180,000 cycles without cracking or whitening when tested on a thermoformed plaque of the thermoplastic polymer in accordance with the cold Ross flex test as described herein below. The thermoplastic polymer can have a cold Ross flex test result of about 140,000 to about 160,000 cycles without cracking or whitening when tested on a thermoformed plaque of the thermoplastic polymer in accordance with the cold Ross flex test as described herein below.

[0089] The thermoplastic polymer can have a modulus from about 5 megapascals (MPa) to about 100 MPa when determined on a thermoformed plaque in accordance with ASTM D412- 98 Standard Test Methods for Vulcanized Rubber and Thermoplastic Rubbers and Thermoplastic Elastomers-Tension with modifications described herein below. The thermoplastic polymer can have a modulus from about 20 MPa to about 80 MPa when determined on a thermoformed plaque in accordance with ASTM D412-98 Standard Test Methods for Vulcanized Rubber and Thermoplastic Rubbers and Thermoplastic Elastomers- Tension with modifications described herein below.

Thermoplastic Polyurethanes

[0010] The polymer can be a polyurethane, such as a thermoplastic polyurethane (also referred to as“TPU”). Additionally, polyurethane can be an elastomeric polyurethane such as a thermoplastic elastomeric polyurethane. The elastomeric polyurethane can include hard and soft segments. The hard segments can comprise or consist of urethane segments (e.g., isocyanate-derived segments). The soft segments can comprise or consist of alkoxy segments (e.g., polyol-derived segments including polyether segments, or polyester segments, or a combination of polyether segments and polyester segments). The polyurethane can comprise or consist essentially of an elastomeric polyurethane having repeating hard segments and repeating soft segments.

[0011] One or more of the polyurethanes can be produced by polymerizing one or more isocyanates with one or more polyols to produce polymer chains having carbamate linkages (-N(CO)O— ) as illustrated below in Formula 1 , where the isocyanate(s) each preferably include two or more isocyanate (— NCO) groups per molecule, such as 2, 3, or 4 isocyanate groups per molecule (although, mono-functional isocyanates can also be optionally included, e.g., as chain terminating units).

The aliphatic diisocyanate-derived segments can be derived substantially (e.g., about 50 percent or more, about 60 percent or more, about 70 percent or more, about 80 percent or more, about 90 percent or more) from linear aliphatic diisocyanates. At least 80% of the aliphatic diisocyanate-derived segments can be derived from aliphatic diisocyanates that are free of side chains.

[0026] In some examples of the polyurethane, the at least one R 2 group includes a polyester group. The polyester group can be derived from the polyesterification of one or more dihydric alcohols (e.g., ethylene glycol, 1 ,3-propylene glycol, 1 ,2-propylene glycol, 1 ,4-butanediol, 1 ,3- butanediol, 2-methylpentanediol-1 , 5, diethylene glycol, 1 ,5-pentanediol, 1 ,5-hexanediol, 1 ,2- dodecanediol, cyclohexanedimethanol, and combinations thereof) with one or more dicarboxylic acids ( e.g ., adipic acid, succinic acid, sebacic acid, suberic acid, methyladipic acid, glutaric acid, pimelic acid, azelaic acid, thiodipropionic acid and citraconic acid and combinations thereof). The polyester group also can be derived from polycarbonate prepolymers, such as poly(hexamethylene carbonate) glycol, polypropylene carbonate) glycol, poly(tetramethylene carbonate)glycol, and poly(nonanemethylene carbonate) glycol. Suitable polyesters can include, for example, polyethylene adipate (PEA), poly(1 ,4-butylene adipate), poly(tetramethylene adipate), poly(hexamethylene adipate), polycaprolactone, polyhexamethylene carbonate, polypropylene carbonate), poly(tetramethylene carbonate), polyponanemethylene carbonate), and combinations thereof.

[0027] At least one R 2 group can include a polycarbonate group. The polycarbonate group can be derived from the reaction of one or more dihydric alcohols (e.g., ethylene glycol, 1 ,3- propylene glycol, 1 ,2-propylene glycol, 1 ,4-butanediol, 1 ,3-butanediol, 2-methylpentanedio1- 1 ,5, diethylene glycol, 1 ,5-pentanediol, 1 ,5-hexanediol, 1 ,2-dodecanediol, cyclohexanedimethanol, and combinations thereof) with ethylene carbonate.

[0028] The aliphatic group can be linear and can include, for example, an alkylene chain having from 1 to 20 carbon atoms or an alkylene chain having from 1 to 20 carbon atoms (e.g., methylene, ethylene, propylene, butylene, pentylene, hexylene, heptylene, octylene, nonylene, decylene, undecylene, dodecylene, tridecylene, ethenylene, propenylene, butenylene, pentenylene, hexenylene, heptenylene, octenylene, nonenylene, decenylene, undecenylene, dodecenylene, tridecenylene). The term “alkene” or“alkylene” refers to a bivalent hydrocarbon. The term“alkylene” refers to a bivalent hydrocarbon molecule or portion of a molecule having at least one double bond.

[0029] The aliphatic and aromatic groups can be substituted with one or more pendant relatively hydrophilic and/or charged groups. The pendant hydrophilic group can include one or more (e.g. , 2, 3, 4, 5, 6, 7, 8, 9, 10 or more) hydroxyl groups. The pendant hydrophilic group includes one or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10 or more) amino groups. In some cases, the pendant hydrophilic group includes one or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10 or more) carboxylate groups. For example, the aliphatic group can include one or more polyacrylic acid group.

[0030] The R 2 group can include charged groups that are capable of binding to a counterion to ionically crosslink the polymer and form ionomers. For example, R 2 is an aliphatic or aromatic group having pendant amino, carboxylate, sulfonate, phosphate, ammonium, or zwitterionic groups, or combinations thereof.

[0031] When a pendant hydrophilic group is present, the pendant hydrophilic group can be at least one polyether group, such as two polyether groups. In other cases, the pendant hydrophilic group is at least one polyester. The pendant hydrophilic group can be a polylactone group (e.g., polyvinylpyrrolidone). Each carbon atom of the pendant hydrophilic group can optionally be substituted with, e.g., an alkyl group having from 1 to 6 carbon atoms.

[0033] The pendant hydrophilic group can be bonded to the aliphatic group or aromatic group through a linker. The linker can be any bifunctional small molecule (e.g., one having from 1 to 20 carbon atoms) capable of linking the pendant hydrophilic group to the aliphatic or aromatic group. For example, the linker can include a diisocyanate group, as previously described herein, which when linked to the pendant hydrophilic group and to the aliphatic or aromatic group forms a carbamate bond. The linker can be 4,4'-diphenylmethane diisocyanate (MDI), as shown below.

[0034] The pendant hydrophilic group can be a polyethylene oxide group and the linking group can be MDI, as shown below.

(Formula 4)

[0035] The pendant hydrophilic group can be functionalized to enable it to bond to the aliphatic or aromatic group, optionally through the linker. For example, when the pendant hydrophilic group includes an alkene group, which can undergo a Michael addition with a sulfhydryl-containing bifunctional molecule (i.e., a molecule having a second reactive group, such as a hydroxyl group or amino group), resulting in a hydrophilic group that can react with the polymer backbone, optionally through the linker, using the second reactive group. For example, when the pendant hydrophilic group is a polyvinylpyrrolidone group, it can react with the sulfhydryl group on mercaptoethanol to result in hydroxyl-functionalized polyvinylpyrrolidone, as shown below.

(Formula 5)

[0036] At least one R 2 group in the polyurethane can include a polytetramethylene oxide group. At least one R 2 group of the polyurethane can include an aliphatic polyol group functionalized with a polyethylene oxide group or polyvinylpyrrolidone group, such as the polyols described in E.P. Patent No. 2 462 908, which is hereby incorporated by reference. For example, the R 2 group can be derived from the reaction product of a polyol (e.g., pentaerythritol or 2,2,3-trihydroxypropanol) and either MDI-derivatized methoxypolyethylene glycol (to obtain compounds as shown in Formulas 6 or 7) or with MDI-derivatized polyvinylpyrrolidone (to obtain compounds as shown in Formulas 8 or 9) that had been previously been reacted with mercaptoethanol, as shown below.

(Formula 9)

[0037] At least one R 2 of the polyurethane can be a polysiloxane, In these cases, the R 2 group can be derived from a silicone monomer of Formula 10, such as a silicone monomer disclosed in U.S. Pat. No. 5,969,076, which is hereby incorporated by reference:

(Formula 10)

wherein: a is 1 to 10 or larger (e.g., 1 , 2, 3, 4, 5, 6, 7, 8, 9, or 10); each R 4 independently is hydrogen, an alkyl group having from 1 to 18 carbon atoms, an alkenyl group having from 2 to 18 carbon atoms, aryl, or polyether; and each R 5 independently is an alkylene group having from 1 to 10 carbon atoms, polyether, or polyurethane.

[0038] Each R 4 group can independently be a H, an alkyl group having from 1 to 10 carbon atoms, an alkenyl group having from 2 to 10 carbon atoms, an aryl group having from 1 to 6 carbon atoms, polyethylene, polypropylene, or polybutylene group. Each R group can independently be selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n- butyl, isobutyl, s-butyl, t-butyl, ethenyl, propenyl, phenyl, and polyethylene groups.

[0039] Each R 5 group can independently include an alkylene group having from 1 to 10 carbon atoms (e.g., a methylene, ethylene, propylene, butylene, pentylene, hexylene, heptylene, octylene, nonylene, or decylene group). Each R 5 group can be a polyether group (e.g., a polyethylene, polypropylene, or polybutylene group). Each R 5 group can be a polyurethane group.

[0040] Optionally, the polyurethane can include an at least partially crosslinked polymeric network that includes polymer chains that are derivatives of polyurethane. The level of crosslinking can be such that the polyurethane retains thermoplastic properties (i.e., the crosslinked thermoplastic polyurethane can be melted and re-solidified under the processing conditions described herein). This crosslinked polymeric network can be produced by polymerizing one or more isocyanates with one or more polyamino compounds, polysulfhydryl compounds, or combinations thereof, as shown in Formulas 1 1 and 12, below:

(Formula 1 1)

(Formula 12)

wherein the variables are as described above. Additionally, the isocyanates can also be chain extended with one or more polyamino or polythiol chain extenders to bridge two or more isocyanates, such as previously described for the polyurethanes of Formula 2.

[0041] The polyurethane chain can be physically crosslinked to another polyurethane chain through e.g., nonpolar or polar interactions between the urethane or carbamate groups of the polymers (the hard segments). The Ri group in Formula 1 , and the Ri and R 3 groups in Formula 2, form the portion of the polymer often referred to as the“hard segment”, and the R 2 group forms the portion of the polymer often referred to as the“soft segment”. The soft segment is covalently bonded to the hard segment. The polyurethane having physically crosslinked hard and soft segments can be a hydrophilic polyurethane (i.e., a polyurethane, including a thermoplastic polyurethane, including hydrophilic groups as disclosed herein).

[0042] The polyurethane can be a thermoplastic polyurethane is composed of MDI, PTMO, and 1 ,4-butylene glycol, as described in U.S. Patent No. 4,523,005. Commercially available polyurethanes suitable for the present use include, but are not limited to those under the tradename “SANCURE” (e.g. , the “SANCURE” series of polymer such as “SANCURE” 20025F) or "TECOPHILIC" (e.g., TG-500, TG-2000, SP-80A-150, SP-93A-100, SP-60D-60) (Lubrizol, Countryside, IL, USA), “PELLETHANE“ 2355-85ATP and 2355-95AE (Dow Chemical Company of Midland, Ml, USA.), "ESTANE" (e.g., ALR G 500, or 58213; Lubrizol, Countryside, IL, USA).

[0043] One or more of the polyurethanes (e.g. , those used in the primer as the coating (e.g. , water-dispersible polyurethane)) can be produced by polymerizing one or more isocyanates with one or more polyols to produce copolymer chains having carbamate linkages (-N(C=0)0- ) and one or more water-dispersible enhancing moieties, where the polymer chain includes one or more water-dispersible enhancing moieties (e.g., a monomer in polymer chain). The water-dispersible polyurethane can also be referred to as “a water-borne polyurethane polymer dispersion.” The water-dispersible enhancing moiety can be added to the chain of Formula 1 or 2 (e.g., within the chain and/or onto the chain as a side chain). Inclusion of the water-dispersible enhancing moiety enables the formation of a water-borne polyurethane dispersion. The term "water-borne" herein means the continuous phase of the dispersion or formulation of about 50 weight percent to 100 weight percent water, about 60 weight percent to 100 weight percent water, about 70 weight percent to 100 weight percent water, or about 100 weight percent water. The term“water-borne dispersion” refers to a dispersion of a component (e.g. , polymer, cross-linker, and the like) in water without co-solvents. The co solvent can be used in the water-borne dispersion and the co-solvent can be an organic solvent. Additional detail regarding the polymers, polyurethanes, isocyanates and the polyols are provided below.

[0044] The polyurethane (e.g., a water-borne polyurethane polymer dispersion) can include one or more water-dispersible enhancing moieties. The water-dispersible enhancing moiety can have at least one hydrophilic (e.g., polyethylene oxide)), ionic or potentially ionic group to assist dispersion of the polyurethane, thereby enhancing the stability of the dispersions. A water-dispersible polyurethane can be formed by incorporating a moiety bearing at least one hydrophilic group or a group that can be made hydrophilic (e.g., by chemical modifications such as neutralization) into the polymer chain. For example, these compounds can be nonionic, anionic, cationic or zwitterionic or the combination thereof. In one example, anionic groups such as carboxylic acid groups can be incorporated into the chain in an inactive form and subsequently activated by a salt-forming compound, such as a tertiary amine. Other water-dispersible enhancing moieties can also be reacted into the backbone through urethane linkages or urea linkages, including lateral or terminal hydrophilic ethylene oxide or ureido units.

[0045] The water-dispersible enhancing moiety can be a one that includes carboxyl groups. Water-dispersible enhancing moiety that include a carboxyl group can be formed from hydroxy-carboxylic acids having the general formula (HO) x Q(COOH) y , where Q can be a straight or branched bivalent hydrocarbon radical containing 1 to 12 carbon atoms, and x and y can each independently be 1 to 3. Illustrative examples include dimethylolpropanoic acid (DMPA), dimethylol butanoic acid (DMBA), citric acid, tartaric acid, glycolic acid, lactic acid, malic acid, dihydroxymalic acid, dihydroxytartaric acid, and the like, and mixtures thereof.

[0046] The water-dispersible enhancing moiety can include reactive polymeric polyol components that contain pendant anionic groups that can be polymerized into the backbone to impart water dispersible characteristics to the polyurethane. Anionic functional polymeric polyols can include anionic polyester polyols, anionic polyether polyols, and anionic polycarbonate polyols, where additional detail is provided in U.S. Pat.

Thermoplastic Polyamides

[0047] The polymer can comprise a polyamide, such as a thermoplastic polyamide. The polyamide can be an elastomeric polyamide such as a thermoplastic elastomeric polyamide. The polyamide can be a polyamide homopolymer having repeating polyamide segments of the same chemical structure. Alternatively, the polyamide can comprise a number of polyamide segments having different polyamide chemical structures (e.g., polyamide 6 segments, polyamide 1 1 segments, polyamide 12 segments, polyamide 66 segments, etc.). The polyamide segments having different chemical structure can be arranged randomly, or can be arranged as repeating blocks.

[0048] The polyamide can be a co-polyamide (i.e., a co-polymer including polyamide segments and non-polyamide segments). The polyamide segments of the co-polyamide can comprise or consist of polyamide 6 segments, polyamide 1 1 segments, polyamide 12 segments, polyamide 66 segments, or any combination thereof. The polyamide segments of the co-polyamide can be arranged randomly, or can be arranged as repeating segments. The polyamide segments can comprise or consist of polyamide 6 segments, or polyamide 12 segments, or both polyamide 6 segment and polyamide 12 segments. In the example where the polyamide segments of the co-polyamide include of polyamide 6 segments and polyamide 12 segments, the segments can be arranged randomly. The non-polyamide segments of the co-polyamide can comprise or consist of polyether segments, polyester segments, or both polyether segments and polyester segments. The co-polyamide can be a co-polyamide, or can be a random co-polyamide. The copolyamide can be formed from the polycondensation of a polyamide oligomer or prepolymer with a second oligomer prepolymer to form a copolyamide (i.e., a co-polymer including polyamide segments. Optionally, the second prepolymer can be a hydrophilic prepolymer.

[0049] The polyamide can be a polyamide-containing block co-polymer. For example, the block co-polymer can have repeating hard segments, and repeating soft segments. The hard segments can comprise polyamide segments, and the soft segments can comprise nonpolyamide segments. The polyamide-containing block co-polymer can be an elastomeric copolyamide comprising or consisting of polyamide-containing block co-polymers having repeating hard segments and repeating soft segments. In block co-polymers, including block co-polymers having repeating hard segments and soft segments, physical crosslinks can be present within the segments or between the segments or both within and between the segments.

[0050] The polyamide itself, or the polyamide segment of the polyamide-containing block co-polymer can be derived from the condensation of polyamide prepolymers, such as lactams, amino acids, and/or diamino compounds with dicarboxylic acids, or activated forms thereof. The resulting polyamide segments include amide linkages (— (CO)NH— ). The term“amino acid” refers to a molecule having at least one amino group and at least one carboxyl group. Each polyamide segment of the polyamide can be the same or different.

[0051] The polyamide or the polyamide segment of the polyamide-containing block co polymer can be derived from the polycondensation of lactams and/or amino acids, and can include an amide segment having a structure shown in Formula 13, below, wherein R 6 group represents the portion of the polyamide derived from the lactam or amino acid.

The R 6 group can be derived from a lactam group having from 3 to 20 carbon atoms, or a lactam group having from 4 to 15 carbon atoms, or a lactam group having from 6 to 12 carbon atoms. The R 6 group can be derived from caprolactam or lauryl lactam. The R 6 group can be derived from one or more amino acids. The R 6 group can be derived from an amino acid group having from 4 to 25 carbon atoms, or an amino acid group having from 5 to 20 carbon atoms, or an amino acid group having from 8 to 15 carbon atoms. The R 6 group can be derived from 12-aminolauric acid or 1 1- aminoundecanoic acid.

[0053] Optionally, in order to increase the relative degree of hydrophilicity of the polyamide- containing block co-polymer, Formula 13 can include a polyamide-polyether block copolymer segment, as shown below:

(Formula 14)

wherein m is 3-20, and n is 1-8. Optionally, m is 4-15, or 6-12 (e.g., 6, 7, 8, 9, 10, 1 1 , or 12), and n is 1 , 2, or 3. For example, m can be 1 1 or 12, and n can be 1 or 3. The polyamide or the polyamide segment of the polyamide-containing block co-polymer can be derived from the condensation of diamino compounds with dicarboxylic acids, or activated forms thereof, and can include an amide segment having a structure shown in Formula 15, below, wherein the R 7 group represents the portion of the polyamide derived from the diamino compound, and the R 8 group represents the portion derived from the dicarboxylic acid compound:

(Formula 15)

[0054] The R 7 group can be derived from a diamino compound that includes an aliphatic group having from 4 to 15 carbon atoms, or from 5 to 10 carbon atoms, or from 6 to 9 carbon atoms. The diamino compound can include an aromatic group, such as phenyl, naphthyl, xylyl, and tolyl. Suitable diamino compounds from which the R 7 group can be derived include, but are not limited to, hexamethylene diamine (HMD), tetramethylene diamine, trimethyl hexamethylene diamine (TMD).m-xylylene diamine (MXD), and 1 ,5-pentamine diamine. The R 8 group can be derived from a dicarboxylic acid or activated form thereof, including an aliphatic group having from 4 to 15 carbon atoms, or from 5 to 12 carbon atoms, or from 6 to 10 carbon atoms. The dicarboxylic acid or activated form thereof from which R 8 can be derived includes an aromatic group, such as phenyl, naphthyl, xylyl, and tolyl groups. Suitable carboxylic acids or activated forms thereof from which R 8 can be derived include adipic acid, sebacic acid, terephthalic acid, and isophthalic acid. The polyamide chain can be substantially free of aromatic groups.

[0055] Each polyamide segment of the polyamide (including the polyamide-containing block co-polymer) can be independently derived from a polyamide prepolymer selected from the group consisting of 12-aminolauric acid, caprolactam, hexamethylene diamine and adipic acid.

[0056] The polyamide can comprise or consist essentially of a poly(ether-block-amide). The poly(ether-block-amide) can be formed from the polycondensation of a carboxylic acid terminated polyamide prepolymer and a hydroxyl terminated polyether prepolymer to form a poly(ether-block-amide), as shown in Formula 16:

(Formula 16)

[0057] The poly(ether block amide) polymer can be prepared by polycondensation of polyamide blocks containing reactive ends with polyether blocks containing reactive ends. Examples include: 1) polyamide blocks containing diamine chain ends with polyoxyalkylene blocks containing carboxylic chain ends; 2) polyamide blocks containing dicarboxylic chain ends with polyoxyalkylene blocks containing diamine chain ends obtained by cyanoethylation and hydrogenation of aliphatic dihydroxylated alpha-omega polyoxyalkylenes known as polyether diols; 3) polyamide blocks containing dicarboxylic chain ends with polyether diols, the products obtained in this particular case being polyetheresteramides. The polyamide block of the poly(ether-block-amide) can be derived from lactams, amino acids, and/or diamino compounds with dicarboxylic acids as previously described. The polyether block can be derived from one or more polyethers selected from the group consisting of polyethylene oxide (PEO), polypropylene oxide (PPO), polytetrahydrofuran (PTHF), polytetramethylene oxide (PTMO), and combinations thereof.

[0058] The poly(ether block amide) polymers can include those comprising polyamide blocks comprising dicarboxylic chain ends derived from the condensation of a, w- aminocarboxylic acids, of lactams or of dicarboxylic acids and diamines in the presence of a chain-limiting dicarboxylic acid. In poly(ether block amide) polymers of this type, a a, w- aminocarboxylic acid such as aminoundecanoic acid can be used; a lactam such as caprolactam or lauryl lactam can be used; a dicarboxylic acid such as adipic acid, decanedioic acid or dodecanedioic acid can be used; and a diamine such as hexamethylenediamine can be used; or various combinations of any of the foregoing. The copolymer can comprise polyamide blocks comprising polyamide 12 or of polyamide 6.

[0059] The poly(ether block amide) polymers can include those comprising polyamide blocks derived from the condensation of one or more a, w-aminocarboxylic acids and/or of one or more lactams containing from 6 to 12 carbon atoms in the presence of a dicarboxylic acid containing from 4 to 12 carbon atoms, and are of low mass, i.e., they have a number- average molecular weight of from 400 to 1000. In poly(ether block amide) polymers of this type, an a, w-aminocarboxylic acid such as aminoundecanoic acid or aminododecanoic acid can be used; a dicarboxylic acid such as adipic acid, sebacic acid, isophthalic acid, butanedioic acid, 1 ,4-cyclohexyldicarboxylic acid, terephthalic acid, the sodium or lithium salt of sulphoisophthalic acid, dimerized fatty acids (these dimerized fatty acids have a dimer content of at least 98 weight percent and are preferably hydrogenated) and dodecanedioic acid HOOC— (CH 2 )IO— COOH can be used; and a lactam such as caprolactam and lauryl lactam can be used; or various combinations of any of the foregoing. The copolymer can comprise polyamide blocks obtained by condensation of lauryl lactam in the presence of adipic acid or dodecanedioic acid and with a number average molecular weight of at least 750 have a melting temperature of from about 127 to about 130 degrees C. The various constituents of the polyamide block and their proportion can be chosen in order to obtain a melting point of less than 150 degrees C, or from about 90 degrees C to about 135 degrees C.

[0060] The poly(ether block amide) polymers can include those comprising polyamide blocks derived from the condensation of at least one a, w-aminocarboxylic acid (or a lactam), at least one diamine and at least one dicarboxylic acid. In copolymers of this type, a a,w- aminocarboxylic acid, the lactam and the dicarboxylic acid can be chosen from those described herein above and the diamine such as an aliphatic diamine containing from 6 to 12 atoms and can be acrylic and/or saturated cyclic such as, but not limited to, hexamethylenediamine, piperazine, 1-aminoethylpiperazine, bisaminopropylpiperazine, tetramethylenediamine, octamethylene-diamine, decamethylenediamine, dodecamethylenediamine, 1 ,5-diaminohexane, 2,2,4-trimethyl-1 ,6-diaminohexane, diamine polyols, isophoronediamine (IPD), methylpentamethylenediamine (MPDM), bis(aminocyclohexyl)methane (BACM) and bis(3-methyl-4-aminocyclohexyl)methane (BMACM) can be used.

[0061] The polyamide can be a thermoplastic polyamide and the constituents of the polyamide block and their proportion can be chosen in order to obtain a melting temperature of less than 150 degrees C, such as a melting point of from about 90 degrees C to about 135 degrees C. The various constituents of the thermoplastic polyamide block and their proportion can be chosen in order to obtain a melting point of less than 150 degrees C, such as from about and 90 degrees C to about 135 degrees C.

[0062] The number average molar mass of the polyamide blocks can be from about 300 grams per mole to about 15,000 grams per mole, from about 500 grams per mole to about 10,000 grams per mole, from about 500 grams per mole to about 6,000 grams per mole, from about 500 grams per mole to about 5,000 grams per mole, or from about 600 grams per mole to about 5,000 grams per mole. The number average molecular weight of the polyether block can range from about 100 to about 6,000, from about 400 to about 3000, or from about 200 to about 3,000. The polyether (PE) content (x) of the poly(ether block amide) polymer can be from about 0.05 to about 0.8 (i.e., from about 5 mole percent to about 80 mole percent). The polyether blocks can be present in the polyamide in an amount of from about 10 weight percent to about 50 weight percent, from about 20 weight percent to about 40 weight percent, or from about 30 weight percent to about 40 weight percent. The polyamide blocks can be present in the polyamide in an amount of from about 50 weight percent to about 90 weight percent, from about 60 weight percent to about 80 weight percent, or from about 70 weight percent to about 90 weight percent.

[0063] The polyether blocks can contain units other than ethylene oxide units, such as, for example, propylene oxide or polytetrahydrofuran (which leads to polytetramethylene glycol sequences). It is also possible to use simultaneously PEG blocks, i.e., those consisting of ethylene oxide units, polypropylene glycol (PPG) blocks, i.e. those consisting of propylene oxide units, and poly(tetramethylene ether)glycol (PTMG) blocks, i.e. those consisting of tetramethylene glycol units, also known as polytetrahydrofuran. PPG or PTMG blocks are advantageously used. The amount of polyether blocks in these copolymers containing polyamide and polyether blocks can be from about 10 weight percent to about 50 weight percent of the copolymer, or from about 35 weight percent to about 50 weight percent.

[0064] The copolymers containing polyamide blocks and polyether blocks can be prepared by any means for attaching the polyamide blocks and the polyether blocks. In practice, two processes are essentially used, one being a 2-step process and the other a one-step process.

[0065] In the two-step process, the polyamide blocks having dicarboxylic chain ends are prepared first, and then, in a second step, these polyamide blocks are linked to the polyether blocks. The polyamide blocks having dicarboxylic chain ends are derived from the condensation of polyamide precursors in the presence of a chain-stopper dicarboxylic acid. If the polyamide precursors are only lactams or a,w-aminocarboxylic acids, a dicarboxylic acid is added. If the precursors already comprise a dicarboxylic acid, this is used in excess with respect to the stoichiometry of the diamines. The reaction usually takes place from about 180 to about 300 degrees C, such as from about 200 degrees to about 290 degrees C, and the pressure in the reactor can be set from about 5 to about 30 bar and maintained for approximately 2 to 3 hours. The pressure in the reactor is slowly reduced to atmospheric pressure and then the excess water is distilled off, for example for one or two hours.

[0066] Once the polyamide having carboxylic acid end groups has been prepared, the polyether, the polyol and a catalyst are then added. The total amount of polyether can be divided and added in one or more portions, as can the catalyst. The polyether is added first and the reaction of the OH end groups of the polyether and of the polyol with the COOH end groups of the polyamide starts, with the formation of ester linkages and the elimination of water. Water is removed as much as possible from the reaction mixture by distillation and then the catalyst is introduced in order to complete the linking of the polyamide blocks to the polyether blocks. This second step takes place with stirring, preferably under a vacuum of at least 50 millibar (5000 pascals) at a temperature such that the reactants and the copolymers obtained are in the molten state. By way of example, this temperature can be from about 100 to about 400 degrees C, such as from about 200 to about 250 degrees C. The reaction is monitored by measuring the torque exerted by the polymer melt on the stirrer or by measuring the electric power consumed by the stirrer. The end of the reaction is determined by the value of the torque or of the target power. The catalyst is defined as being any product which promotes the linking of the polyamide blocks to the polyether blocks by esterification. The catalyst can be a derivative of a metal (M) chosen from the group formed by titanium, zirconium and hafnium. The derivative can be prepared from a tetraalkoxides consistent with the general formula M(OR) 4 , in which M represents titanium, zirconium or hafnium and R, which can be identical or different, represents linear or branched alkyl radicals having from 1 to 24 carbon atoms.

[0067] The catalyst can comprise a salt of the metal (M), particularly the salt of (M) and of an organic acid and the complex salts of the oxide of (M) and/or the hydroxide of (M) and an organic acid. The organic acid can be formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, cyclohexanecarboxylic acid, phenylacetic acid, benzoic acid, salicylic acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, maleic acid, fumaric acid, phthalic acid or crotonic acid. The organic acid can be an acetic acid or a propionic acid. M can be zirconium and such salts are called zirconyl salts, e.g. , the commercially available product sold under the name zirconyl acetate.

[0068] The weight proportion of catalyst can vary from about 0.01 to about 5 percent of the weight of the mixture of the dicarboxylic polyamide with the polyetherdiol and the polyol. The weight proportion of catalyst can vary from about 0.05 to about 2 percent of the weight of the mixture of the dicarboxylic polyamide with the polyetherdiol and the polyol.

[0069] In the one-step process, the polyamide precursors, the chain stopper and the polyether are blended together; what is then obtained is a polymer having essentially polyether blocks and polyamide blocks of highly variable length, but also the various reactants that have reacted randomly, which are distributed randomly along the polymer chain. They are the same reactants and the same catalyst as in the two-step process described above. If the polyamide precursors are only lactams, it is advantageous to add a little water. The copolymer has essentially the same polyether blocks and the same polyamide blocks, but also a small portion of the various reactants that have reacted randomly, which are distributed randomly along the polymer chain. As in the first step of the two-step process described above, the reactor is closed and heated, with stirring. The pressure established is from about 5 to about 30 bar. When the pressure no longer changes, the reactor is put under reduced pressure while still maintaining vigorous stirring of the molten reactants. The reaction is monitored as previously in the case of the two-step process.

[0070] The proper ratio of polyamide to polyether blocks can be found in a single poly(ether block amide), or a blend of two or more different composition poly(ether block amide)s can be used with the proper average composition. It can be useful to blend a block copolymer having a high level of polyamide groups with a block copolymer having a higher level of polyether blocks, to produce a blend having an average level of polyether blocks of about 20 to about 40 weight percent of the total blend of poly(amid-block-ether) copolymers, or about 30 to about 35 weight percent. The copolymer can comprise a blend of two different poly(ether-block- amide)s comprising at least one block copolymer having a level of polyether blocks below 35 weight percent, and a second poly(ether-block-amide) having at least 45 weight percent of polyether blocks.

[0071] Exemplary commercially available copolymers include, but are not limited to, those available under the tradenames of “VESTAMID” (Evonik Industries, Essen, Germany); “PLATAMID” (Arkema, Colombes, France), e.g., product code H2694;“PEBAX” (Arkema), e.g., product code“PEBAX MH1657” and “PEBAX MV1074”; “PEBAX RNEW” (Arkema); “GRILAMID” (EMS-Chemie AG, Domat-Ems, Switzerland), or also to other similar materials produced by various other suppliers.

[0072] The polyamide can be physically crosslinked through, e.g., nonpolar or polar interactions between the polyamide groups of the polymers. In examples where the polyamide is a copolyamide, the copolyamide can be physically crosslinked through interactions between the polyamide groups, and optionally by interactions between the copolymer groups. When the co-polyamide is physically crosslinked thorough interactions between the polyamide groups, the polyamide segments can form the portion of the polymer referred to as the hard segment, and copolymer segments can form the portion of the polymer referred to as the soft segment. For example, when the copolyamide is a poly(ether-block-amide), the polyamide segments form the hard segments of the polymer, and polyether segments form the soft segments of the polymer. Therefore, in some examples, the polymer can include a physically crosslinked polymeric network having one or more polymer chains with amide linkages.

[0073] The polyamide segment of the co-polyamide can include polyamide-1 1 or polyamide- 12 and the polyether segment can be a segment selected from the group consisting of polyethylene oxide, polypropylene oxide, and polytetramethylene oxide segments, and combinations thereof.

[0091] The polyamide can be partially or fully covalently crosslinked, as previously described herein. In some cases, the degree of crosslinking present in the polyamide is such that, when it is thermally processed, e.g., in the form of a yarn or fiber to form the articles of the present disclosure, the partially covalently crosslinked thermoplastic polyamide retains sufficient thermoplastic character that the partially covalently crosslinked thermoplastic polyamide is melted during the processing and re-solidifies.

Thermoplastic Polyesters

[0074] The polymers can comprise a polyester. The polyester can comprise a thermoplastic polyester. Additionally, the polyester can be an elastomeric polyester such as a thermoplastic polyester. The polyester can be formed by reaction of one or more carboxylic acids, or its ester-forming derivatives, with one or more bivalent or multivalent aliphatic, alicyclic, aromatic or araliphatic alcohols or a bisphenol. The polyester can be a polyester homopolymer having repeating polyester segments of the same chemical structure. Alternatively, the polyester can comprise a number of polyester segments having different polyester chemical structures (e.g. , polyglycolic acid segments, polylactic acid segments, polycaprolactone segments, polyhydroxyalkanoate segments, polyhydroxybutyrate segments, etc.). The polyester segments having different chemical structure can be arranged randomly, or can be arranged as repeating blocks.

[0075] Exemplary carboxylic acids that can be used to prepare a polyester include, but are not limited to, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, nonane dicarboxylic acid, decane dicarboxylic acid, undecane dicarboxylic acid, terephthalic acid, isophthalic acid, alkyl-substituted or halogenated terephthalic acid, alkyl-substituted or halogenated isophthalic acid, nitro-terephthalic acid, 4,4'-diphenyl ether dicarboxylic acid, 4,4'- diphenyl thioether dicarboxylic acid, 4,4'-diphenyl sulfone-dicarboxylic acid, 4,4'-diphenyl alkylenedicarboxylic acid, naphthalene-2, 6-dicarboxylic acid, cyclohexane- 1 , 4-dicarboxylic acid and cyclohexane- 1 , 3-dicarboxylic acid. Exemplary diols or phenols suitable for the preparation of the polyester include, but are not limited to, ethylene glycol, diethylene glycol, 1 ,3-propanediol, 1 ,4-butanediol, 1 ,6-hexanediol, 1 ,8-octanediol, 1 ,10-decanediol, 1 ,2- propanediol, 2, 2-dimethyl-1 , 3-propanediol, 2,2,4-trimethylhexanediol, p-xylenediol, 1 ,4- cyclohexanediol, 1 ,4-cyclohexane dimethanol, and bis-phenol A.

[0076] The polyester can be a polybutylene terephthalate (PBT), a polytrimethylene terephthalate, a polyhexamethylene terephthalate, a poly-1 ,4-dimethylcyclohexane terephthalate, a polyethylene terephthalate (PET), a polyethylene isophthalate (PEI), a polyarylate (PAR), a polybutylene naphthalate (PBN), a liquid crystal polyester, or a blend or mixture of two or more of the foregoing.

[0077] The polyester can be a co-polyester (i.e., a co-polymer including polyester segments and non-polyester segments). The co-polyester can be an aliphatic co-polyester (i.e., a co polyester in which both the polyester segments and the non-polyester segments are aliphatic). Alternatively, the co-polyester can include aromatic segments. The polyester segments of the co-polyester can comprise or consist essentially of polyglycolic acid segments, polylactic acid segments, polycaprolactone segments, polyhydroxyalkanoate segments, polyhydroxybutyrate segments, or any combination thereof. The polyester segments of the co-polyester can be arranged randomly, or can be arranged as repeating blocks.

[0078] For example, the polyester can be a block co-polyester having repeating blocks of polymeric units of the same chemical structure which are relatively harder (hard segments), and repeating blocks of the same chemical structure which are relatively softer (soft segments). In block co- polyesters, including block co-polyesters having repeating hard segments and soft segments, physical crosslinks can be present within the blocks or between the blocks or both within and between the blocks. The polymer can comprise or consist essentially of an elastomeric co-polyester having repeating blocks of hard segments and repeating blocks of soft segments.

[0079] The non-polyester segments of the co-polyester can comprise or consist essentially of polyether segments, polyamide segments, or both polyether segments and polyamide segments. The co-polyester can be a block co-polyester, or can be a random co-polyester. The co-polyester can be formed from the polycodensation of a polyester oligomer or prepolymer with a second oligomer prepolymer to form a block copolyester. Optionally, the second prepolymer can be a hydrophilic prepolymer. For example, the co-polyester can be formed from the polycondensation of terephthalic acid or naphthalene dicarboxylic acid with ethylene glycol, 1 ,4-butanediol, or 1-3 propanediol. Examples of co-polyesters include polyethylene adipate, polybutylene succinate, poly(3-hydroxbutyrate-co-3-hydroxyvalerate), polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyethylene naphthalate, and combinations thereof. The co-polyamide can comprise or consist of polyethylene terephthalate.

[0080] The polyester can be a block copolymer comprising segments of one or more of polybutylene terephthalate (PBT), a polytrimethylene terephthalate, a polyhexamethylene terephthalate, a poly-1 , 4-dimethylcyclohexane terephthalate, a polyethylene terephthalate (PET), a polyethylene isophthalate (PEI), a polyarylate (PAR), a polybutylene naphthalate (PBN), and a liquid crystal polyester. For example, a suitable polyester that is a block copolymer can be a PET/PEI copolymer, a polybutylene terephthalate/tetraethylene glycol copolymer, a polyoxyalkylenediimide diacid/polybutylene terephthalate copolymer, or a blend or mixture of any of the foregoing.

[0081] The polyester can be a biodegradable resin, for example, a copolymerized polyester in which poly(a-hydroxy acid) such as polyglycolic acid or polylactic acid is contained as principal repeating units.

[0092] The disclosed polyesters can be prepared by a variety of polycondensation methods known to the skilled artisan, such as a solvent polymerization or a melt polymerization process.

Thermoplastic Polyolefins

[0082] The polymers can comprise or consist essentially of a polyolefin. The polyolefin can be a thermoplastic polyolefin. Additionally, the polyolefin can be an elastomeric polyolefin such as a thermoplastic elastomeric polyolefin. Exemplary polyolefins can include polyethylene, polypropylene, and olefin elastomers (e.g., metallocene-catalyzed block copolymers of ethylene and a-olefins having 4 to about 8 carbon atoms). The polyolefin can be a polymer comprising a polyethylene, an ethylene-a-olefin copolymer, an ethylene-propylene rubber (EPDM), a polybutene, a polyisobutylene, a poly-4-methylpent-1-ene, a polyisoprene, a polybutadiene, an ethylene-methacrylic acid copolymer, and an olefin elastomer such as a dynamically cross-linked polymer obtained from polypropylene (PP) and an ethylene- propylene rubber (EPDM), and blends or mixtures of the foregoing. Further exemplary polyolefins include polymers of cycloolefins such as cyclopentene or norbornene.

[0083] It is to be understood that polyethylene, which optionally can be crosslinked, is inclusive a variety of polyethylenes, including low density polyethylene (LDPE), linear low density polyethylene (LLDPE), (VLDPE) and (ULDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), high density and high molecular weight polyethylene (HDPE-HMW), high density and ultrahigh molecular weight polyethylene (HDPE-UHMW), and blends or mixtures of any the foregoing polyethylenes. A polyethylene can also be a polyethylene copolymer derived from monomers of monoolefins and diolefins copolymerized with a vinyl, acrylic acid, methacrylic acid, ethyl acrylate, vinyl alcohol, and/or vinyl acetate. Polyolefin copolymers comprising vinyl acetate-derived units can be a high vinyl acetate content copolymer, e.g., greater than about 50 weight percent vinyl acetate-derived composition.

[0084] The polyolefin can be formed through free radical, cationic, and/or anionic polymerization by methods well known to those skilled in the art (e.g., using a peroxide initiator, heat, and/or light). The disclosed polyolefin can be prepared by radical polymerization under high pressure and at elevated temperature. Alternatively, the polyolefin can be prepared by catalytic polymerization using a catalyst that normally contains one or more metals from group IVb, Vb, Vlb or VIII metals. The catalyst usually has one or more than one ligand, typically oxides, halides, alcoholates, esters, ethers, amines, alkyls, alkenyls and/or aryls that can be either p- or s-coordinated complexed with the group IVb, Vb, Vlb or VIII metal. The metal complexes can be in the free form or fixed on substrates, typically on activated magnesium chloride, titanium(lll) chloride, alumina or silicon oxide. The metal catalysts can be soluble or insoluble in the polymerization medium. The catalysts can be used by themselves in the polymerization or further activators can be used, typically a group la, lla and/or Ilia metal alkyls, metal hydrides, metal alkyl halides, metal alkyl oxides or metal alkyloxanes. The activators can be modified conveniently with further ester, ether, amine or silyl ether groups.

[0085] Suitable polyolefins can be prepared by polymerization of monomers of monoolefins and diolefins as described herein. Exemplary monomers that can be used to prepare the polyolefin include, but are not limited to, ethylene, propylene, 1 -butene, 1-pentene, 1 -hexene, 2-methyl-1-propene, 3-methyl-1-pentene, 4-methyl- 1-pentene, 5-methyl- 1 -hexene and mixtures thereof.

[0086] Suitable ethylene-a-olefin copolymers can be obtained by copolymerization of ethylene with an a-olefin such as propylene, butene-1 , hexene-1 , octene-1 ,4-methyl-1- pentene or the like having carbon numbers of 3 to 12.

[0087] Suitable dynamically cross-linked polymers can be obtained by cross-linking a rubber component as a soft segment while at the same time physically dispersing a hard segment such as PP and a soft segment such as EPDM by using a kneading machine such as a Banbury mixer and a biaxial extruder.

[0088] The polyolefin can be a mixture of polyolefins, such as a mixture of two or more polyolefins disclosed herein above. For example, a suitable mixture of polyolefins can be a mixture of polypropylene with polyisobutylene, polypropylene with polyethylene (for example PP/HDPE, PP/LDPE) or mixtures of different types of polyethylene (for example LDPE/HDPE).

[0089] The polyolefin can be a copolymer of suitable monoolefins monomers or a copolymer of a suitable monoolefins monomer and a vinyl monomer. Exemplary polyolefin copolymers include ethylene/propylene copolymers, linear low density polyethylene (LLDPE) and mixtures thereof with low density polyethylene (LDPE), propylene/but-1-ene copolymers, propylene/isobutylene copolymers, ethylene/but-1-ene copolymers, ethylene/hexene copolymers, ethylene/methylpentene copolymers, ethylene/heptene copolymers, ethylene/octene copolymers, propylene/butadiene copolymers, isobutylene/isoprene copolymers, ethylene/alkyl acrylate copolymers, ethylene/alkyl methacrylate copolymers, ethylene/vinyl acetate copolymers and their copolymers with carbon monoxide or ethylene/acrylic acid copolymers and their salts (ionomers) as well as terpolymers of ethylene with propylene and a diene such as hexadiene, dicyclopentadiene or ethylidene-norbornene; and mixtures of such copolymers with one another and with polymers mentioned in 1) above, for example polypropylene/ethylene-propylene copolymers, LDPE/ethylene-vinyl acetate copolymers (EVA), LDPE/ethylene-acrylic acid copolymers (EAA), LLDPE/EVA, LLDPE/EAA and alternating or random polyalkylene/carbon monoxide copolymers and mixtures thereof with other polymers, for example polyamides.

[0090] The polyolefin can be a polypropylene homopolymer, a polypropylene copolymers, a polypropylene random copolymer, a polypropylene block copolymer, a polyethylene homopolymer, a polyethylene random copolymer, a polyethylene block copolymer, a low density polyethylene (LDPE), a linear low density polyethylene (LLDPE), a medium density polyethylene, a high density polyethylene (HDPE), or blends or mixtures of one or more of the preceding polymers.

[0091] The polyolefin can be a polypropylene. The term“polypropylene,” as used herein, is intended to encompass any polymeric composition comprising propylene monomers, either alone or in mixture or copolymer with other randomly selected and oriented polyolefins, dienes, or other monomers (such as ethylene, butylene, and the like). Such a term also encompasses any different configuration and arrangement of the constituent monomers (such as atactic, syndiotactic, isotactic, and the like). Thus, the term as applied to fibers is intended to encompass actual long strands, tapes, threads, and the like, of drawn polymer. The polypropylene can be of any standard melt flow (by testing); however, standard fiber grade polypropylene resins possess ranges of Melt Flow Indices between about 1 and 1000.

[0092] The polyolefin can be a polyethylene. The term“polyethylene,” as used herein, is intended to encompass any polymeric composition comprising ethylene monomers, either alone or in mixture or copolymer with other randomly selected and oriented polyolefins, dienes, or other monomers (such as propylene, butylene, and the like). Such a term also encompasses any different configuration and arrangement of the constituent monomers (such as atactic, syndiotactic, isotactic, and the like). Thus, the term as applied to fibers is intended to encompass actual long strands, tapes, threads, and the like, of drawn polymer. The polyethylene can be of any standard melt flow (by testing); however, standard fiber grade polyethylene resins possess ranges of Melt Flow Indices between about 1 and 1000.

[0093] The thermoplastic can further comprise one or more processing aids. The processing aid can be a non-polymeric material. These processing aids can be independently selected from the group including, but not limited to, curing agents, initiators, plasticizers, mold release agents, lubricants, antioxidants, flame retardants, dyes, pigments, reinforcing and nonreinforcing fillers, fiber reinforcements, and light stabilizers.

Thermoplastic Additives

[0094] In some aspects, a disclosed thermoplastic polymer or a disclosed fiber, filament, yarn, film, sheet or textile comprising a thermoplastic polymer can further comprise an additive. The additive can be incorporated directly into a fiber, filament, yarn, film, sheet or textile or alternatively, applied thereto. In addition, an additive can be incorporated into a polymer melt prior to extrusion, forming a sheet or film, and polymer blends. Additives that can be used in the disclosed thermoplastic polymers, fibers, filaments, yarns, or fabrics include, but are not limited to, dyes, pigments, colorants, ultraviolet light absorbers, hindered amine light stabilizers, antioxidants, processing aids or agents, plasticizers, lubricants, emulsifiers, pigments, dyes, optical brighteners, rheology additives, catalysts, flow-control agents, slip agents, crosslinking agents, crosslinking boosters, halogen scavengers, smoke inhibitors, flame-proofing agents, antistatic agents, fillers, or mixtures of two or more of the foregoing. When used, an additive can be present in an amount of from about 0.01 wt% to about 10 wt%, about 0.025 wt% to about 5 wt%, or about 0.1 wt% to 3 wt%, where the wt% is based upon the sum of the material components in the thermoplastic composition, fiber, filament, yarn, or fabric.

[0095] Individual components can be mixed together with the other components of the thermoplastic composition in a continuous mixer or a batch mixer, e.g., in an intermeshing rotor mixer, such as an Intermix mixer, a twin screw extruder, in a tangential rotor mixer such as a Banbury mixer, using a two-roll mill, or some combinations of these to make a composition comprising a thermoplastic polymer and an additive. The mixer can blend the components together via a single step or multiple steps, and can mix the components via dispersive mixing or distributive mixing to form the resulting thermoplastic composition. This step is often referred to as“compounding.”

[0096] In some aspects, the additive is an antioxidant such as ascorbic acid, an alkylated monophenol, an alkylthiomethylphenol, a hydroquinone or alkylated hydroquinone, a tocopherol, a hydroxylated thiodiphenyl ether, an alkylidene bisphenol, a benzyl compound, a hydroxylated malonate, an aromatic hydroxybenzl compound, a triazine compound, a benzylphosphonate, an acylaminophenol, an ester of p-(3,5-di-tert-butyl-4- hydroxyphenyl)propionic acid with mono- or polyhydric alcohols, an ester of b- (5-tert-butyl-4- hydroxy-3-methylphenyl)propionic acid with mono- or polyhydric alcohols, an ester of b-(3,5- dicyclohexyl-4-hydroxyphenyl)propionic acid with mono- or polyhydric alcohols, an ester of

The free-radical initiator can be present in an amount from about 0.001 wt% to about 1.0 wt%. A variety of radical initiators can be used as the radical sources to make thermoplastic compositions have a crosslinked structure. Suitable radical initiators applied include peroxides, sulfurs, and sulfides.

[0130] In some aspects, the additive is a colorant. The term“colorant,” as used herein, means a compound providing color to a substrate, e.g., a disclosed thermoplastic composition. A colorant can include without limitation a dye, a pigment, and the like, and mixtures and combinations thereof. In some instances, the colorant can be an organic or inorganic pigment, a dye, or mixtures or combinations thereof.

In a further aspect, the disclosed thermoplastic composition can comprise between about 0.01 wt% and about 3 wt% relative to the weight of the composition.

Textiles

[0001] As discussed herein above, a disclosed composite element can comprise a textile. The textile can be a non-woven textile, a knit textile, or a woven textile. The textile can include a plurality of fibers, a plurality of filaments, or a plurality of yarns, such that the plurality of fibers, the plurality of filaments, or the plurality of yarns comprise a first thermoplastic material. In some instances, the plurality of fibers, the plurality of filaments, or the plurality of yarns can have a first and a second fiber, a first filament and a second filament, or a first yarn and a second yarn, such that each of the first and the second fiber, filament, or yarn, independently have a first thermoplastic material and an additional thermoplastic material. For example, a textile can have a plurality of yarns, such that the first yarn comprises a first thermoplastic material and the second yarn comprises an additional thermoplastic material. The first thermoplastic material and the additional thermoplastic material can be the same or different in terms of polymer composition or a property, e.g., melting temperature of the polymer.

[0002] A“textile” may be defined as any material manufactured from fibers, filaments, or yarns characterized by flexibility, fineness, and a high ratio of length to thickness. Textiles generally fall into two categories. The first category includes textiles produced directly from webs of filaments or fibers by randomly interlocking to construct non-woven fabrics and felts. The second category includes textiles formed through a mechanical manipulation of yarn, thereby producing a woven fabric, a knitted fabric, a braided fabric, a crocheted fabric, and the like.

[0003] The terms“filament,”“fiber,” or“fibers” as used herein refer to materials that are in the form of discrete elongated pieces that are significantly longer than they are wide. The fiber can include natural, manmade or synthetic fibers. The fibers may be produced by conventional techniques, such as extrusion, electrospinning, interfacial polymerization, pulling, and the like. The fibers can include carbon fibers, boron fibers, silicon carbide fibers, titania fibers, alumina fibers, quartz fibers, glass fibers, such as E, A, C, ECR, R, S, D, and NE glasses and quartz, or the like. The fibers can be fibers formed from synthetic polymers capable of forming fibers such as poly(ether ketone), polyimide, polybenzoxazole, poly(phenylene sulfide), polyesters, polyolefins (e.g., polyethylene, polypropylene), aromatic polyamides (e.g., an aramid polymer such as para-aramid fibers and meta-aramid fibers), aromatic polyimides, polybenzimidazoles, polyetherimides, polytetrafluoroethylene, acrylic, modacrylic, poly(vinyl alcohol), polyamides, polyurethanes, and copolymers such as polyether-polyurea copolymers, polyester-polyurethanes, polyether block amide copolymers, or the like. The fibers can be natural fibers (e.g., silk, wool, cashmere, vicuna, cotton, flax, hemp, jute, sisal). The fibers can be man-made fibers from regenerated natural polymers, such as rayon, lyocell, acetate, triacetate, rubber, and poly(lactic acid).

[0004] The fibers can have an indefinite length. For example, man-made and synthetic fibers are generally extruded in substantially continuous strands. Alternatively, the fibers can be staple fibers, such as, for example, cotton fibers or extruded synthetic polymer fibers can be cut to form staple fibers of relatively uniform length. The staple fiber can have a have a length of about 1 millimeter to 100 centimeters or more as well as any increment therein (e.g., 1 millimeter increments).

[0005] The fiber can have any of a variety of cross-sectional shapes. Natural fibers can have a natural cross-section, or can have a modified cross-sectional shape (e.g., with processes such as mercerization). Man-made or synthetic fibers can be extruded to provide a strand having a predetermined cross-sectional shape. The cross-sectional shape of a fiber can affect its properties, such as its softness, luster, and wicking ability. The fibers can have round or essentially round cross sections. Alternatively, the fibers can have non-round cross sections, such as flat, oval, octagonal, rectangular, wedge-shaped, triangular, dog-bone, multi-lobal, multi-channel, hollow, core-shell, or other shapes.

[0006] The fiber can be processed. For example, the properties of fibers can be affected, at least in part, by processes such as drawing (stretching) the fibers, annealing (hardening) the fibers, and/or crimping or texturizing the fibers.

[0007] In some cases a fiber can be a multi-component fiber, such as one comprising two or more co-extruded polymeric materials. The two or more co-extruded polymeric materials can be extruded in a core-sheath, islands-in-the-sea, segmented-pie, striped, or side-by-side configuration. A multi-component fiber can be processed in order to form a plurality of smaller fibers (e.g., microfibers) from a single fiber, for example, by remove a sacrificial material.

[0008] The fiber can be a carbon fiber such as TARIFYL produced by Formosa Plastics Corp. of Kaohsiung City, Taiwan, (e.g., 12,000, 24,000, and 48,000 fiber tows, specifically fiber types TC-35 and TC-35R), carbon fiber produced by SGL Group of Wiesbaden, Germany (e.g., 50,000 fiber tow), carbon fiber produced by Hyosung of Seoul, South Korea, carbon fiber produced by Toho Tenax of Tokyo, Japan, fiberglass produced by Jushi Group Co., LTD of Zhejiang, China (e.g., E6, 318, silane-based sizing, filament diameters 14, 15, 17, 21 , and 24 micrometers), and polyester fibers produced by Amann Group of Bonningheim, Germany (e.g., SERAFILE 200/2 non-lubricated polyester filament and SERAFILE COMPHIL 200/2 lubricated polyester filament).

[0009] A plurality of fibers includes 2 to hundreds or thousands or more fibers. The plurality of fibers can be in the form of bundles of strands of fibers, referred to as tows, or in the form of relatively aligned staple fibers referred to as sliver and roving. A single type fiber can be used either alone or in combination with one or more different types of fibers by co-mingling two or more types of fibers. Examples of co-mingled fibers include polyester fibers with cotton fibers, glass fibers with carbon fibers, carbon fibers with aromatic polyimide (aramid) fibers, and aromatic polyimide fibers with glass fibers.

[0010] As used herein, the term“yarn” refers to an assembly formed of one or more fibers, wherein the strand has a substantial length and a relatively small cross-section, and is suitable for use in the production of textiles by hand or by machine, including textiles made using weaving, knitting, crocheting, braiding, sewing, embroidery, or rope-making techniques. Thread is a type of yarn commonly used for sewing.

[0011] Yarns can be made using fibers formed of natural, man-made and synthetic materials. Synthetic fibers are most commonly used to make spun yarns from staple fibers, and filament yarns. Spun yarn is made by arranging and twisting staple fibers together to make a cohesive strand. The process of forming a yarn from staple fibers typically includes carding and drawing the fibers to form sliver, drawing out and twisting the sliver to form roving, and spinning the roving to form a strand. Multiple strands can be plied (twisted together) to make a thicker yarn. The twist direction of the staple fibers and of the plies can affect the final properties of the yarn. A filament yarn can be formed of a single long, substantially continuous filament, which is conventionally referred to as a “monofilament yarn,” or a plurality of individual filaments grouped together. A filament yarn can also be formed of two or more long, substantially continuous filaments which are grouped together by grouping the filaments together by twisting them or entangling them or both. As with staple yarns, multiple strands can be plied together to form a thicker yarn.

[0012] Once formed, the yarn can undergo further treatment such as texturizing, thermal or mechanical treating, or coating with a material such as a synthetic polymer. The fibers, yarns, or textiles, or any combination thereof, used in the disclosed articles can be sized. Sized fibers, yarns, and/or textiles are coated on at least part of their surface with a sizing composition selected to change the absorption or wear characteristics, or for compatibility with other materials. The sizing composition facilitates wet-out and wet-through of the coating or resin upon the surface and assists in attaining desired physical properties in the final article. An exemplary sizing composition can comprise, for example, epoxy polymers, urethane-modified epoxy polymers, polyester polymers, phenol polymers, polyamide polymers, polyurethane polymers, polycarbonate polymers, polyetherimide polymers, polyamideimide polymers, polystylylpyridine polymers, polyimide polymers bismaleimide polymers, polysulfone polymers, polyethersulfone polymers, epoxy-modified urethane polymers, polyvinyl alcohol polymers, polyvinyl pyrrolidone polymers, and mixtures thereof.

[0013] Two or more yarns can be combined, for example, to form composite yarns such as single- or double-covered yarns, and corespun yarns. Accordingly, yarns may have a variety of configurations that generally conform to the descriptions provided herein.

[0014] The yarn can comprise at least one thermoplastic material (e.g., one or more of the fibers can be made of thermoplastic material). The yarn can be made of a thermoplastic material. The yarn can be coated with a layer of a material such as a thermoplastic material.

[0015] The linear mass density or weight per unit length of a yarn can be expressed using various units, including denier (D) and tex. Denier is the mass in grams of 9000 meters of yarn. The linear mass density of a single filament of a fiber can also be expressed using denier per filament (DPF). Tex is the mass in grams of a 1000 meters of yarn. Decitex is another measure of linear mass, and is the mass in grams for a 10,000 meters of yarn.

[0016] As used herein, tenacity is understood to refer to the amount of force (expressed in units of weight, for example: pounds, grams, centinewtons or other units) needed to break a yarn (i.e., the breaking force or breaking point of the yarn), divided by the linear mass density of the yarn expressed, for example, in (unstrained) denier, decitex, or some other measure of weight per unit length. The breaking force of the yarn is determined by subjecting a sample of the yarn to a known amount of force, for example, using a strain gauge load cell such as an INSTRON brand testing system (Norwood, MA, USA). Yarn tenacity and yarn breaking force are distinct from burst strength or bursting strength of a textile, which is a measure of how much pressure can be applied to the surface of a textile before the surface bursts.

[0017] Generally, in order for a yarn to withstand the forces applied in an industrial knitting machine, the minimum tenacity required is approximately 1.5 grams per Denier. Most yarns formed from commodity polymeric materials generally have tenacities in the range of about 1.5 grams per Denier to about 4 grams per Denier. For example, polyester yarns commonly used in the manufacture of knit uppers for footwear have tenacities in the range of about 2.5 to about 4 grams per Denier. Yarns formed from commodity polymeric materials which are considered to have high tenacities generally have tenacities in the range of about 5 grams per Denier to about 10 grams per Denier. For example, commercially available package dyed polyethylene terephthalate yarn from National Spinning (Washington, NC, USA) has a tenacity of about 6 grams per Denier, and commercially available solution dyed polyethylene terephthalate yarn from Far Eastern New Century (Taipei, Taiwan) has a tenacity of about 7 grams per Denier. Yarns formed from high performance polymeric materials generally have tenacities of about 1 1 grams per Denier or greater. For example, yarns formed of aramid fiber typically have tenacities of about 20 grams per Denier, and yarns formed of ultra-high molecular weight polyethylene (UHMWPE) having tenacities greater than 30 grams per Denier are available from Dyneema (Stanley, NC, USA ) and Spectra (Honeywell-Spectra, Colonial Heights, VA, USA).

[0018] Various techniques exist for mechanically manipulating yarns to form a textile. Such techniques include, for example, interweaving, intertwining and twisting, and interlooping. Interweaving is the intersection of two yarns that cross and interweave at right angles to each other. The yarns utilized in interweaving are conventionally referred to as“warp” and“weft.” A woven textile includes include a warp yarn and a weft yarn. The warp yarn extends in a first direction, and the weft strand extends in a second direction that is substantially perpendicular to the first direction. Intertwining and twisting encompasses various procedures, such as braiding and knotting, where yarns intertwine with each other to form a textile. Interlooping involves the formation of a plurality of columns of intermeshed loops, with knitting being the most common method of interlooping. The textile may be primarily formed from one or more yarns that are mechanically-manipulated, for example, through interweaving, intertwining and twisting, and/or interlooping processes, as mentioned above.

[0019] The textile can be a non-woven textile. Generally, a non-woven textile or fabric is a sheet or web structure made from fibers and/or yarns that are bonded together. The bond can be a chemical and/or mechanical bond, and can be formed using heat, solvent, adhesive or a combination thereof. Exemplary non-woven fabrics are flat or tufted porous sheets that are made directly from separate fibers, molten plastic and/or plastic film. They are not made by weaving or knitting and do not necessarily require converting the fibers to yarn, although yarns can be used as a source of the fibers. Non-woven textiles are typically manufactured by putting small fibers together in the form of a sheet or web (similar to paper on a paper machine), and then binding them either mechanically (as in the case of felt, by interlocking them with serrated or barbed needles, or hydro-entanglement such that the inter-fiber friction results in a stronger fabric), with an adhesive, or thermally (by applying binder (in the form of powder, paste, or polymer melt) and melting the binder onto the web by increasing temperature). A non-woven textile can be made from staple fibers (e.g., from wetlaid, airlaid, carding/crosslapping processes), or extruded fibers (e.g., from meltblown or spunbond processes, or a combination thereof), or a combination thereof. Bonding of the fibers in the non-woven textile can be achieved with thermal bonding (with or without calendering), hydro-entanglement, ultrasonic bonding, needlepunching (needlefelting), chemical bonding (e.g., using binders such as latex emulsions or solution polymers or binder fibers or powders), meltblown bonding (e.g., fiber is bonded as air attenuated fibers intertangle during simultaneous fiber and web formation).

[0022] As used herein, the term“and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as“at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

[0023] As used in the specification and the appended claims, the singular forms“a,”“an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to“a polymer,”“a mold,” or“a foamed preform,” including, but not limited to, two or more such polymers, molds, or preform, and the like.

[0024] As used herein, in substance or substantially means at least 50 percent, 60 percent, 75 percent, 90 percent, 95 percent, or more, as determined based on weight or volume.

[0025] Reference to "a" chemical compound refers one or more molecules of the chemical compound, rather than being limited to a single molecule of the chemical compound. Furthermore, the one or more molecules may or may not be identical, so long as they fall under the category of the chemical compound. Thus, for example, "a" polyamide is interpreted to include one or more polymer molecules of the polyamide, where the polymer molecules may or may not be identical (e.g., different molecular weights and/or isomers).

[0026] It should be noted that ratios, concentrations, amounts, and other numerical data can be expressed herein in a range format. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure, e.g. the phrase“xto y” includes the range from‘x’ to y as well as the range greater than‘x’ and less than y . The range can also be expressed as an upper limit, e.g.‘about x, y, z, or less’ and should be interpreted to include the specific ranges of‘about x’,‘about y’, and ‘about z’ as well as the ranges of ‘less than x’, less than y’, and‘less than z’. Likewise, the phrase‘about x, y, z, or greater’ should be interpreted to include the specific ranges of‘about x’,‘about y’, and‘about z’ as well as the ranges of‘greater than x’, greater than y’, and‘greater than z’. In addition, the phrase“about‘x’ to‘y’”, where‘x’ and y are numerical values, includes “about‘x’ to about‘y’”. It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. To illustrate, a numerical range of“about 0.1 percent to 5 percent” should be interpreted to include not only the explicitly recited values of about 0.1 percent to about 5 percent, but also include individual values (e.g., 1 percent, 2 percent, 3 percent, and 4 percent) and the sub-ranges (e.g., 0.5 percent, 1.1 percent, 2.4 percent, 3.2 percent, and 4.4 percent) within the indicated range.

[0027] As used herein, the terms“about,”“approximate,”“at or about,” and“substantially” mean that the amount or value in question can be the exact value or a value that provides equivalent results or effects as recited in the claims or taught herein. That is, it is understood that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art such that equivalent results or effects are obtained. In some circumstances, the value that provides equivalent results or effects cannot be reasonably determined. In such cases, it is generally understood, as used herein, that“about” and“at or about” mean the nominal value indicated plus or minusl O percent variation unless otherwise indicated or inferred. In general, an amount, size, formulation, parameter or other quantity or characteristic is“about,”“approximate,” or“at or about” whether or not expressly stated to be such. It is understood that where“about,”“approximate,” or“at or about” is used before a quantitative value, the parameter also includes the specific quantitative value itself, unless specifically stated otherwise.

[0028] As used herein, the terms “optional” or“optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

[0029] As used herein, the term“units” can be used to refer to individual (co)monomer units such that, for example, styrenic repeat units refers to individual styrene (co)monomer units in the polymer. In addition, the term“units” can be used to refer to polymeric block units such that, for example,“styrene repeating units” can also refer to polystyrene blocks;“units of polyethylene” refers to block units of polyethylene;“units of polypropylene” refers to block units of polypropylene;“units of polybutylene” refers to block units of polybutylene, and so on. Such use will be clear from the context.

[0030] The term "copolymer" refers to a polymer having two or more monomer species, and includes terpolymers (i.e., copolymers having three monomer species).

[0031] Unless otherwise specified, temperatures referred to herein are based on atmospheric pressure (i.e. one atmosphere).
