METHODS AND COMPOSITIONS FOR COOLING YARNS AND FABRICS, AND ARTICLES COMPRISING SAME

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This Application claims the benefit of U.S. Provisional Application No. 63/124,477, filed on December 11 , 2020, which is incorporated herein by reference in its entirety.

BACKGROUND

[0002] Textile materials that have cooling properties, e.g., minimize heat retention, mitigate heat absorption from the external environment, and/or provide a cooling tactile sensation or perception are highly desirable. Such textile materials would have a number of applications, including sportswear, apparel, upholstery, and other textile applications, in which thermal comfort would improve performance and/or the user experience. In addition, it is desirable that incorporation of cooling properties into textile materials be accompanied by improvements in one or more of Qmax, thermal effusivity, wicking, drying time, blocking UV and/or IR radiation, and the like.

[0003] However, for widespread use of such textile materials cost and ease of manufacturing considerations are paramount. That is, it is important that a textile material having improved cooling properties meet market requirements in terms of cost, be accessible from a manufacturing perspective, and be scalable. For example, systems and processes for preparing a cooling composition comprising nanoparticle materials in a form that can be used in a masterbatch for use with standard methods of yarn spinning such as melt spinning, dry spinning, gel spinning and solvent spinning are lacking in the field.

[0004] Thus, despite advances in textile research, there remains an important need for materials and processes that can be used in production of yarns and fabrics that have nanoparticle cooling compositions providing improved cooling properties, e.g., minimize heat retention, mitigate heat absorption from the external environment, and/or provide a cooling tactile sensation or perception, while maintaining the hand feel and function. These needs and other needs are satisfied by the present disclosure.

DETAILED DESCRIPTION

[0028] Many modifications and other embodiments disclosed herein will come to mind to one skilled in the art to which the disclosed compositions and methods pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosures are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. The skilled artisan will recognize many variants and adaptations of the aspects described herein. These variants and adaptations are intended to be included in the teachings of this disclosure and to be encompassed by the claims herein.

[0029] Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.

[0030] As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features which may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure.

[0031] Any recited method can be carried out in the order of events recited or in any other order that is logically possible. That is, unless otherwise expressly stated, it is in no way intended that any method or aspect set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not specifically state in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including matters of logic with respect to arrangement of steps or operational flow, plain meaning derived from grammatical organization or punctuation, or the number or type of aspects described in the specification.

[0032] All publications mentioned herein are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited. The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present invention is not entitled to antedate such publication by virtue of prior invention. Further, the dates of publication provided herein can be different from the actual publication dates, which can require independent confirmation.

[0033] While aspects of the present disclosure can be described and claimed in a particular statutory class, such as the system statutory class, this is for convenience only and one of skill in the art will understand that each aspect of the present disclosure can be described and claimed in any statutory class.

[0034] It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosed compositions and methods belong. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0035] Prior to describing the various aspects of the present disclosure, the following definitions are provided and should be used unless otherwise indicated. Additional terms may be defined elsewhere in the present disclosure.

A. DEFINITIONS

[0036] As used herein, “comprising” is to be interpreted as specifying the presence of the stated features, integers, steps, or components as referred to, but does not preclude the presence or addition of one or more features, integers, steps, or components, or groups thereof. Additionally, the term “comprising” is intended to include examples and aspects encompassed by the terms “consisting essentially of’ and “consisting of.” Similarly, the term “consisting essentially of’ is intended to include examples encompassed by the term “consisting of.”

[0037] As used herein, the term “produced from” is synonymous to “comprising”. As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains” or “containing,” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.

[0038] The transitional phrase “consisting of’ excludes any element, step, or ingredient not specified. If in the claim, such a phrase would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consisting of’ appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.

[0039] The transitional phrase “consisting essentially of’ is used to define a composition, method or apparatus that includes materials, steps, features, components, or elements, in addition to those literally discussed, provided that the additional materials, steps features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term “consisting essentially of’ occupies a middle ground between “comprising” and “consisting of’.

[0040] Further, unless expressly stated to the contrary, “or” refers to an inclusive “or” and not to an exclusive “or”. For example, a condition A “or” B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0041] 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 yarn,” or “a fabric,” including, but not limited to, two or more such polymers, yarns, or fabrics, and the like. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular.

[0042] It should be noted that ratios, concentrations, amounts, and other numerical data can be expressed herein in a range format. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed. Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms a further aspect. For example, if the value “about 10” is disclosed, then “10” is also disclosed.

[0043] When a range is expressed, a further aspect includes from the one particular value and/or to the other particular value. For example, 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’”.

[0044] 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% to 5%” should be interpreted to include not only the explicitly recited values of about 0.1% to about 5%, but also include individual values (e.g., about 1%, about 2%, about 3%, and about 4%) and the sub-ranges (e.g., about 0.5% to about 1.1%; about 5% to about 2.4%; about 0.5% to about 3.2%, and about 0.5% to about 4.4%, and other possible sub-ranges) within the indicated range. To further illustrate, when a range of “1 to 5” is recited, the recited range should be construed as including ranges “1 to 4”, “1 to 3”, “1-2”, “1-2 & 4-5”, “1-3 & 5”, and the like. [0045] 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 ±10% 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.

[0046] The terms “decrease” , “reduced”, “reduction” “decrease” or “inhibit” are all used herein generally to mean a decrease by a statistically significant amount. However, for avoidance of doubt, “reduced”, “reduction” or “decrease” or “inhibit” means a decrease by at least 10% as compared to a reference level, for example a decrease by at least about 20%, or at least about 30%, or at least about 40%, or at least about 50%, or at least about 60%, or at least about 70%, or at least about 80%, or at least about 90% or up to and including a 100% decrease (e.g. absent level as compared to a reference sample), or any decrease between 10-100% as compared to a reference level.

[0047] The terms “increased”, “increase” or “enhance” or “activate” are all used herein to generally mean an increase by a statically significant amount; for the avoidance of any doubt, the terms “increased”, “increase” or “enhance” or “activate” means an increase of at least 10% as compared to a reference level, for example an increase of at least about 20%, or at least about 30%, or at least about 40%, or at least about 50%, or at least about 60%, or at least about 70%, or at least about 80%, or at least about 90% or up to and including a 100% increase or any increase between 10-100% as compared to a reference level, or at least about a 2-fold, or at least about a 3-fold, or at least about a 4-fold, or at least about a 5-fold or at least about a 10-fold increase, or any increase between 2-fold and 10-fold or greater as compared to a reference level.

[0048] The term “statistically significant” or “significantly” refers to statistical significance and generally means at least two standard deviations (2SD) away from a reference level. The term refers to statistical evidence that there is a difference. It is defined as the probability of making a decision to reject the null hypothesis when the null hypothesis is actually true.

[0049] As used herein the terms “weight percent,” “wt%,” and “wt. %,” which can be used interchangeably, indicate the percent by weight of a given component based on the total weight of a composition of which it is a component, unless otherwise specified. That is, unless otherwise specified, all wt% values are based on the total weight of the composition. It should be understood that the sum of wt% values for all components in a disclosed composition or formulation are equal to 100. Alternatively, if the wt% value is based on the total weight of a subset of components in a composition, it should be understood that the sum of wt% values the specified components in the disclosed composition or formulation are equal to 100.

[0050] As used herein, the term “effective amount” refers to an amount that is sufficient to achieve the desired modification of a physical property of the composition or material. For example, an “effective amount” of a cooling composition refers to an amount that is sufficient to achieve the desired improvement in the property modulated by the cooling composition, e.g. achieving the desired enhancement in Qmax compared to a yarn or fabric without the effective amount. The specific level in terms of wt% in a composition required as an effective amount will depend upon a variety of factors including the amount and type of polymer and yarn, fabric use, and the like.

[0051] 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.

[0052] The term “microscale” as used herein comprises a surface having a measurable feature in the range of from about 1 to about 1000 pm.

[0053] The term “nanoscale” as used herein comprises a surface having a measurable feature in the range of from about 1 to about 1000 nm.

[0054] The term “nanoparticle” as used herein comprises a nanoscale deposit of a homogenous or heterogeneous material. Nanoparticles may be regular or irregular in shape and may be formed from a plurality of co-deposited particles that form a composite nanoscale particle. Nanoparticles may be generally spherical in shape or have a composite shape formed from a plurality of co-deposited generally spherical particles. Exemplary shapes for the nanoparticles include, but are not limited to, spherical, rod, elliptical, cylindrical, disc, and the like. In some embodiments, the nanoparticles have a substantially spherical shape.

[0055] As used herein, reference to an element, e.g., a core component comprises Al, Ca, Cu, Fe...Zr” or “a core component comprises aluminum, calcium, copper, iron...zirconium,” is intended to be inclusive of any form or valency of the element as appropriate for a given compound or material in which the element is part of the composition of the compound or material, unless otherwise specified. That is, it is understood that a reference to a particular element in a composition or material is inclusive of ionic forms of the element in typical oxidation states for that element if the composition or material comprises the element as an ionic compound; covalently bonded forms of the element if the composition or material comprises the element as an covalent compound; and elemental forms (i.e., oxidation state of 0) as suitable or appropriate for the indicated if the composition or material comprises the element in an oxidation state of 0, e.g., Al as metallic aluminum.

[0056] As used herein, “nanozinc” and “nanozinc oxide,” can be used interchangeably, and refer to zinc oxide (i.e., zinc (I) oxide, zinc (II) oxide, zinc (III) oxide or combinations thereof) in which the zinc oxide is in a form comprising substantially a particulates, a powder, or combinations thereof, in which the particles and/or powder are nano-sized. That is the particles or powder, as appropriate, generally have a size of about 1 nm to about 1000 nm.

[0057] The term “Denier” or abbreviated as “d” as used herein will be understood to be a relative measure of a fineness (or linear density) of a fiber or yarn. Denier is equivalent numerically to the weight in grams per 9,000 meters length of the material. The term “decitex” is another measure of a fineness of a fiber, which is equivalent to the weight in grams of a 10,000 meter length of the material.

[0058] As used herein, “multicomponent” refers to a fiber composed of more than one polymer.

[0059] As used herein, the term “fiber” refers to refers to any slender, elongated structure that can be carded, combed, or otherwise formed into a thread or filament. A fiber can comprise a natural material (e.g., cotton, linen or wool) or an artificial material (e.g., nylon, polyester). A fiber is a material in which the length to diameter ratio is greater than about 10. Fiber is typically classified according to its fineness. Fiber is generally defined as having a fiber fineness greater than about 15 Denier, usually greater than about 30 Denier. Fine Denier fiber generally refers to a fiber having a fineness less than about 15 Denier. Examples of fibers include “staple fibers”, a term that is well-known in the textile art. A reference to “fiber” of “fibers” may mean or include individual fibers or a plurality or bulk of fibers as the situation requires. A plurality of fibers may comprise fibers of different compositions or may be substantially uniform in composition. Thus, by way of illustration, a reference to “natural fiber” or “synthetic fiber” may mean and may include a single fiber of such type or may mean any quantity or plurality of such fibers and they may be comprised in threads, felts, yarns, fabrics materials etc., all as will be apparent from the context.

[0060] The fiber can be a synthetic fiber or a natural or organic fiber. As one of skill in the art is well aware, smoothness of the outer surfaces is significantly varied between different fibers. Accordingly, the outer surface of the fiber can be smooth or rough. By way of example only, manmade fibers, such as polyester fibers, usually have a smooth outer surface. In contrast, natural fibers, such as cotton, usually have a rough outer surface. One consequence of the roughness of the outer surface is that rough surfaces take more fluid to completely cover the surface per unit diameter.

[0061] As used herein, “fiber” refers to any one of the various types of matter that form the basic elements of a textile and that is characterized by a flexible, macroscopically homogeneous body having a high ratio of length to width and being small in cross section, and may include one or more fibrous materials (e.g., fibers or filaments). It is understood that “fiber” includes “filaments.”

[0062] As used herein, “filament” refers generally to a continuous fiber of extremely long length, whereas a “staple fiber” means a fiber of finite length. A staple fiber can be a natural fiber or a fiber cut from, for example, a filament.

[0063] As used herein, the term “synthetic fiber” refers to a fiber that is not prepared from naturally occurring filaments and include, but are not limited to, fibers made from components by polymerization, polycondensation or polyaddition. Materials for forming the synthetic fibers include, but are limited to, polyesters, polyamides such as nylons, polyacrylics, polyurethanes such as spandex, elastanes, elastodienes, fluoro fibers, acrylics, modacrylics, aramids, polyvinyl chlorides, polyvinylidene chloride, polyethylenes, polypropylenes and vinylals. Synthetic fibers include fibers formed from petroleum products. Synthetic fiber containing materials are those that contain both the purely synthetic fiber and also natural materials.

[0064] “Polymers” are understood to include, but are not limited to, homopolymers, copolymers, such as for example, block, graft, random and alternating copolymers, terpolymers, etc. and blends and modifications thereof.

[0065] The term “polyamide” as used herein means the well-known fiber-forming substance that is a long-chain synthetic polyamide. The term particularly relates to poly (s-caprolactam; “nylon 6”) and poly (hexamethylene adipamide; “nylon 6,6”) as well as their copolymers.

[0066] The term “polyester” as used herein is intended to embrace polymers wherein at least 85% of the recurring units are condensation products of dicarboxylic acids and dihydroxy alcohols with linkages created by formation of ester units. This includes aromatic, aliphatic, saturated, and unsaturated di-acids and di-alcohols. The term “polyester” as used herein also includes copolymers (such as block, graft, random and alternating copolymers), blends, and modifications thereof. A common example of a polyester is polyethylene terephthalate) which is a condensation product of ethylene glycol and terephthalic acid. [0067] As used herein, the term “polyurethane-polyurea copolymer” refers to synthetic polymers sold as “spandex” or “elastane” under the brand names of LYCRA (Invista), ELASPAN (Invista), ACEPORA (Taekwang), CREORA (Hyosung), INVIYA (Indorama Corporation), ROICA and DORLASTAN (Asahi Kasei), LINEL (Fillattice), and ESPA (Toyobo).

[0068] The term “filament fiber” including “monofilament fiber” and “multifilament fiber” means a fiber comprising one or more continuous strands of natural or synthetic material of indefinite (i.e., not predetermined) length, as opposed to a “staple fiber” which is a discontinuous strand of fiber of definite length (i.e., a strand which has been cut or otherwise divided into segments of a predetermined length)..

[0069] Filaments are generally formed by the melting of polymer pellets or another source of polymer which is then forced through an extrusion die to produce a continuous fiber. A filament can be a single continuous extrusion, or may be a chopped apart extrusion such as to form a staple. This fiber can then be texturized directly (which is uncommon), or can be combined with other filaments to form a filament bundle with the resultant filament bundle can then be texturized.

[0070] As used herein, “composite fiber” refers to a continuous fiber in which two distinct polymers are intimately adhered to each other along the length of the fiber. In some instances, a composite filament is a filament or fiber that is composed of at least two distinct polymers which have been spun together to form a single filament or fiber. By the term “distinct polymers” it is meant that each of the at least two polymeric components are arranged in distinct substantially constantly positioned zones across the cross-section of the composite fiber and extend substantially continuously along the length of the fiber. Composite fibers are distinguished from fibers that are extruded from a homogeneous melt blend of polymeric materials in which zones of distinct polymers are not formed. The at least two distinct polymeric components useable herein can be chemically different or they can be chemically the same polymer, but have different physical characteristics, such as facticity, intrinsic viscosity, melt viscosity, die swell, density, crystallinity, and melting point or softening point. One or more of the polymeric components in the composite fiber can be a blend of different polymers. A composite fiber can have a fiber cross-section that is, for example, a side-by-side, eccentric sheath-core, concentratic sheath-core, or other suitable cross-section.

[0071] As understood herein, “filaments”, which will be considered single strand synthetic fiber or polymer extrusions, and “yarns” or “filament bundles” are structures comprising a number of filaments combined together.

I. METHODS OF PREPARING COOLING FILMS.

[0194] In various aspects, the present disclosure pertains to methods of preparing a disclosed cooling film can be prepared by a sputtering process. As known to the skilled artisan, sputtering is a physical technique used to deposit particles, e.g., nanoparticles, onto a substrate, e.g., a film, a sheet, or other material. Without wishing to be bound by a particular theory, it is believed that sputtering occurs when an ionized gas molecule is used to displace atoms of a specific material. These atoms then bond at the atomic level to a substrate and create a thin film. Several types of sputtering processes exist, including ion beam, diode, magnetron, and gas flow sputtering.

[0195] In various aspects, the present disclosure pertains to methods of forming a cooling film, the methods comprising: placing a plurality of sputtering targets in a sputtering chamber of sputtering device; placing a substrate in a substrate holder disposed above the plurality of sputtering targets; applying a DC magnetic field to the sputtering targets; and depositing a layer of sputtered material on a surface of the substrate; wherein the plurality of sputtering targets comprise a sputtering material selected from aluminum, zinc oxide, and combinations thereof; wherein the layer of sputtered material comprises nanoparticles of a cooling composition; wherein the cooling composition comprises a material selected from aluminum, zinc oxide, and combinations thereof; and wherein the substrate comprises a polymer; thereby forming a cooling film comprising a substrate having thereon a layer of sputtered material.

[0196] Magnetron sputtering coating is a vacuum coating process that is categorized under physical vapor deposition (PVD). The basic mechanism of magnetron sputtering technique consists of a target or a metal precursor (which is made of the desired material to be deposited on the film), which is bombarded with high energy ions of inert gases (such as argon, helium). The forceful collision of these energetic ions with the target ejects target metal atoms into space. These metal atoms are then deposited on the substrate material forming a metallic film. Since sputtering takes place in a high-energy environment, it creates a virtually an unbreakable bond between the film and its substrate at the atomic level, creating one of the thinnest, most uniform, and most cost-effective films possible

Zinc oxide was obtained as a powder having an average particle size of 2-10 pm. Aluminum was obtained in metallic form. Polyester film was sourced from suppliers in Taiwan and had a thickness of 23 pm.

[0628] Sputtering Targets. The sputtering targets were prepared by compression molding or liquid molding as described herein.

[0629] Zinc oxide sputtering target: Zinc oxide powder was compression molded at a pressure of 2 ton/in ³ and a temperature of 1007 °C in vacuum. The target prepared by compression molding for use in the sputtering method was about 3.5 kg with dimensions of 30 cm long x 15 cm wide x up to 18 mm thick.

[0630] Aluminum sputtering target: Aluminum metal was melted at 660 °C and poured into a mold. The molded target prepared for use in the sputtering method was about 3.0 kg with dimensions of 30 cm long x 15 cm wide x up to 18 mm thick.

[0631] Sputtering method: preparation of zinc oxide coated polyeseter film. Up to five zinc targets, prepared as described above, were placed in the sputter coating machine at a distance of 7-12 cm from the substrate to be sputter coated, i.e., in the present example the substrate was polyester film having a 23 pm thickness. The targets were negatively charged and the film was positively charged. The polyester film was sputtered using high energy ionized argon gas molecules under vacuum. The sputtering process deposits a single, uniform layer of sputtered material comprising graphene, silica and zinc oxide having a thickness of 10-15 nm on the polyester film. The layer of sputtered material provides essentially 100% coverage of the substrate film. The target ion hopping temperature was about 7500-8000 °C, and the surface contact temperature of the film was about 65-70 °C. The argon gas was supplied in the sputtering chamber at the rate of 1-1.5 m ³ /hr and a continuous DC magnetic field was used having a frequency range of 20,000 Hz.

[0632] Sputtering method: preparation of aluminum coated polyeseter film. An aluminum target, prepared as described above, was placed in the sputter coating machine at a distance of 7-12 cm from the substrate to be sputter coated, i.e., in the present example the substrate was polyester film having a 23 pm thickness. The target was negatively charged and the film was positively charged. The polyester film was sputtered using high energy ionized argon gas molecules under vacuum. The sputtering process deposits a single, uniform layer of sputtered material comprising aluminum having a thickness of 5-8 nm on the polyester film. The layer of sputtered material provides essentially 100% coverage of the substrate film. The target ion hopping temperature was about 7500-8000 °C, and the surface contact temperature of the film was about 65-70 °C. The argon gas was supplied in the sputtering chamber at the rate of 1-1.5 m ³ /hr and a continuous DC magnetic field was used having a frequency range of 20,000 Hz.

2. EXAMPLE 2: PREPARATION OF COOLING MASTERBATCH.

[0633] A coated film, e.g., the graphene/silica/zinc oxide coated polyester film or the aluminum coated polyester film, was melted at a temperature of 280-290 °C in a hopper and extruded in a twin-screw extruder to form extruded masterbatch pellets comprising polyester and cooling material. Extrusion was carried out at 100 kg/hr (450 cycles/min) and 14.7 Ibf/sq. in. Pellets of each type of polyester and cooling material prepared above, i.e., masterbatch pellets comprising polyester, graphene, silica, and zinc oxide (designated herein as the PE/graphene/silica/ZnO masterbatch) and masterbatch pellets comprising polyester and aluminum (designated herein as the PE/AI masterbatch) were mixed in an amount of 70 wt% PE/AI masterbatch and 30 wt% PE/graphene/silica/ZnO masterbatch in a hopper, melted at a temperature of 280-290 °C, and extruded as described above to form cooling masterbatch pellets.

[0634] Cooling masterbatch pellets (10 wt%) were mixed with virgin polyester pellets (90 wt%) are dried at a temperature of 170 °C to reduce the moisture content and thus prevent the hydrolysis of the polymer which leads to the deterioration of its properties. Following moisture reduction, the mixture of virgin polyester and cooling masterbatch pellets are melted and extruded through a spinneret at a temperature of 265-290 °C at 4000 m/min. The extruded material is solidified by a flow of cooling air in a cooling zone, and then drawn through tension rollers at a temperature above the material glass transition temperature, e.g., 69 °C, to improve polymer chain orientation and increase filament strength.

4. EXAMPLE 4: PREPARATION OF COOLING DRAWN TEXTURIZED YARN.

[0635] The filament yarn prepared as described above was subjected to texturizing by heat setting in a twisted condition to provide a yarn with greater bulk, higher stretch and better aesthetic properties. Briefly, the cooling filament yarn prepared above was passed through heated rollers (i.e., heated to temperature above glass transition temperature) and simultaneously twisted and drawn to produce a draw texturized yarn. The resultant cooling texturized yarn was 75 Denier I 72 filament, semi dull, Draw Texturized Yarn (75D/72 SD DTY).

5. EXAMPLE 5: ANALYSIS COOLING FILMS, COOLING MASTERBATCH PELLETS, AND COOLING YARNS.

[0636] Samples of cooling films, masterbatch pellets, and yarns, prepared as described above, were coated with Gold-Palladium coating using a Leica EM ACE600 Coater in the presence of Argon and Nitrogen gases. The coating process was carried out for 20 minutes to deposit a layer of 15 nm of coating on the samples. The samples were then loaded in a FEI Teneo scanning electron microscope (FEI, Inc., Hillsboro, Oregon, US) and examined under the Concentric backscatter detector under a range of potential differences (5-20 volts) and magnifications (200-700X). All SEM images were obtained at the Georgia Electron Microscopy Center (University of Georgia, 151 Barrow Hall, 115 D.W. Brooks Drive, Athens GA 30602, USA). The FEI Teneo was used to obtain images of all the sputtered films, pellets and yarns.

[0640] The cooling texturized yarn prepared above was used to prepare a woven cooling fabric. Briefly, the sputtered cooling yarn (Polyester 75D/72 DTY SD) prepared above was woven in a plain 1x1 weave using a commercial weaving machine to provide a disclosed cooling woven fabric. The disclosed cooling woven fabric had a weight of 79 grams per square meter. A comparator woven fabric was prepared having a similar weight (79 grams per square meter) using a 75D/72 DTY SD polyester yarn comprising cooling materials that were micronsized versus the nano-sized cooling materials of the representative disclosed cooling woven fabric. Each of the woven fabrics (the disclosed fabric and the comparator fabric) were desized, scoured, bleached and finished before being used in Qmax analysis. Qmax was determined in accordance with FTTS-FA-019 as specified by Committee of Conformity Assessment of Accreditation and Certification on Functional and Technical Textiles (Taiwan). The samples analyzed and Qmax results are summarized in Table 3 below. The data below show that the disclosed cooling fabric utilizing a cooling yarn with nano-sized cooling materials had a significantly improved Qmax (0.251 W/cm ² ) compared to the comparator cooling fabric Qmax (0.198 W/cm ² ). The approximately ~ 27% improvement in Qmax demonstrates that reduction of the cooling material particle size using the disclosed method of preparing a cooling yarn having nano-sized cooling materials from masterbatch materials prepared using the disclosed sputtering method provides a superior cooling fabric.
