TECHNICAL FIELD

[0002] This specification describes using abrasion and washing to produce denim fabric with varying amounts of color fade.

BACKGROUND

[0003] The production of denim clothing faces challenges because it is environmentally costly at multiple stages of the process. For example, production of denim clothing requires a fabric dyeing (indigo dying) process. This dying process itself typically requires large amounts of water and reagents. Under conventional methods of indigo dyeing, whether done continuously or in closed batch, when the denim is removed from the dyebath, the leuco indigo used in the dying process almost instantaneously reacts with oxygen in the air and initially turns green (the combination of partial blue and partial yellow) as it transitions to the insoluble, intensely colored blue indigo that is the hallmark of denim fabric. Current fabrication methods leave significant amounts of the dye liquor on the surfaces of textile substrates. This unavoidably oxidizes and leaves behind considerable surface indigo that must be removed by washing. The waste water from this washing is often polluted post manufacturing and requires processing. In addition, after dyeing and cut-and trim processing of fabric, to produce clothing with desired appearance and feel (e.g., slightly or heavily worn), it is typical practice to wash the clothing (e.g., stone washing , acid washing, and/or enzyme washing) for varying lengths of time, which requires even more water and power. [0004] As companies increasingly seek to offer products with improved sustainability, reduction in water and energy usage is becoming more important. However, there remains a need for these products to deliver equal or better performance than conventionally washed and dyed alternatives at a comparable price point.

[0005] Given the need for production methods with lower environmental impact, improved methods of dyeing and preparing fabric for the production of clothing are needed in the art. SUMMARY

[0006] The present disclosure addresses the shortcomings identified in the background by providing improved methods for converting dyed fabric into fabric. Such fabric can then be used to make articles of clothing.

[0007] In one aspect, a method for processing denim is provided. The method comprises abrading an initial fabric by passing the initial fabric through an abrader at a first predetermined linear speed, thereby obtaining a pre-washed fabric with an abraded texture. The abrader comprises one or more sanding boards, where each respective sanding board in the one or more sanding boards has a respective surface that contacts the initial fabric while spinning about a respective axis at a respective center of the respective board during the abrading. The method further comprises washing the pre-washed fabric with an ozone composition, thereby obtaining an ozone washed fabric. The method optionally further comprises using the ozone washed fabric to produce the article of clothing.

[0008] In some embodiments, the ozone washed fabric is denim.

[0009] In some embodiments, the method further comprises, prior to the abrading, dyeing a yam comprising a plurality of textile fibers with a blue dye by coating a surface of the yam with the blue dye and weaving the yam to form the initial fabric. In some embodiments, the blue dye is an indigo dye, a sulphur dye, or a combination of an indigo and a sulphur dye. [0010] In some embodiments, the plurality of textile fibers is natural fibers, regenerated fibers, or synthetic fibers. In some embodiments, the plurality of textile fibers comprises flax, kapok, hemp, jute, ramie, sisal, abaca, coir, or Pineapple fiber. In some embodiments, the plurality of textile fibers comprises rayon, polyester, polyamide, aramid, olefin, elastomer, or acrylic.

In some embodiments, the plurality of textile fibers is blended fibers.

[0011] In some embodiments, the yam is monofilament yam or multifilament yam. In some embodiments, the yam is staple or spun yam. In some embodiments, the yam is a covered yam. In some embodiments, the covered yam comprises a core and a wrap. In some embodiments, the core is an elastomeric fiber core, an elastic core, a SPANDEX monofilament core, or a LYCRA core. In some embodiments, the wrap is a filament-yam wrap, a spun-yam outer cover, a spun-yam wrap, or a rat cross-sectional filament wrap. [0012] In some embodiments, the dyeing is performed using foam indigo dye in the presence of nitrogen.

[0013] In some embodiments, each respective surface of each sanding board in the one or more sanding boards spins about the respective axis of the respective sanding board at the respective center of the sanding board at a rate of between 100 and 3000 revolutions per minute, a rate of between 500 and 2800 revolutions per minute, or a rate of between 800 and 2500 revolutions per minute.

[0014] In some embodiments, each respective surface of each sanding boards in the one or more sanding boards is cylindrical and has a diameter of between 2 and 20 inches. In some embodiments, each respective surface of each sanding boards in the one or more sanding boards is electroplated at a specified grit. In some embodiments, the specified grit is between grit 400 and grit 2400 Federation Europeenne des Fabricants de Produits Abrasifs F standard (FEPA F) for sharpening stones and wheels. In some embodiments, the one or more sanding boards comprises between 3 and 30 sanding boards.

[0015] In some embodiments, the first predetermined linear speed is between 10 meters per minute and 100 meters per minute.

[0016] In some embodiments, the abrading and washing cause the pre-washed fabric to exhibit a predetermined amount of color fade relative to the initial fabric.

[0017] In some embodiments, the predetermined amount of color fade causes the ozone washed fabric to be dark indigo, medium indigo, or light indigo.

[0018] In some embodiments, the article of clothing is a pair of denim jeans. In some embodiments, the article of clothing is a denim shirt, a denim dress, a denim skirt, or a denim handbag.

[0019] In some embodiments, the ozone composition is between 5 g/Nm ³ ozone and 100 g/Nm ³ ozone.

[0020] In some embodiments, the ozone washed fabric has a width of between 80 centimeters and 400 centimeters. In some embodiments, the ozone washed fabric has a length of at least 50 meters. In some embodiments, the ozone washed fabric has a length of at least 100 meters. In some embodiments, using the ozone washed fabric to produce the article of clothing comprises cutting, making, and trimming with the ozone washed fabric to form the article of clothing.

[0021] In some embodiments, the method further comprises washing and drying the yam after the dyeing and before the weaving or abrading. In some embodiments, the method further comprises agitation washing the article of clothing, and drying the article of clothing. In some embodiments, the agitation washing of the article of clothing comprises a sonic washing in a water bath.

[0022] In some embodiments, the method further comprises patterning the article of clothing with a laser to produce one or more laser designs within the article of clothing.

DETAILED DESCRIPTION

[0038] The systems and methods described herein provide improved processes for producing articles of clothing with lower environmental impact. In particular, by the combination of a foam indigo dyeing method, an abrasive indigo removal method, and an ozone-washing method, the disclosed systems and methods require less water usage and energy relative to conventional clothing fabrication techniques. In addition, the systems and methods described herein produce articles of clothing with higher durability and size consistency (e.g., stone washing and other conventional washing methods typically reduce the structural integrity of articles of clothing).

[0039] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that the present disclosure may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

[0040] The implementations described herein provide various technical solutions for training a reference model to determining a tumor fraction for a subject.

[0041] Definitions. As used herein, the term “denim” refers to a twill-woven cotton or primarily cotton textile fabric produced from yam comprising a plurality of fibers (e.g., a warp-face fabric). In some embodiments, denim comprises warp yam that is dyed with indigo dye, sulphur dye, or a combination of indigo and sulphur dye and weft yam that is undyed (e.g., grey). In some embodiment denim is a “right-handed warp-face uneven twill” in which the warp yams are colored with white filling yams (e.g. weft). In such embodiments, the warp-faced twill causes the colored warp yams to be predominant on the face and the white filling yams to be predominant on the back. In typical embodiments, the warp yams are indigo dyed, created the fabric in “blue jeans.” In some embodiments, the denim fabric is made out of 2/1 twills.

[0042] As used herein, the term “indigo” refers to either naturally obtained or synthetically produced indigo, having the IUPAC name 3H-indol-3-l, 2-(l,3-dihydro-3-oxo-2H-indol-2- ylidene)- 1,2-dihydro- which has the structure:

Naturally occurring indigo is obtained from sources such as I. tinctoria (also known as Indigofera sumatrana), Strobilanthes cusia, I. suffruticosa , Indigofera arrecta, Is. tinctoria (woad) and Polygonum tinctorum (dyer’s knotweed). As used herein, the term “indigo” further refers to indigo that has been converted to the water soluble form leuco indigo (e.g., by fermentation or bacterial reduction, chemical reduction, electrochemical reduction, catalytic hydrogenation, or electrocatalytic hydrogenation. See, Woodhead Publishing Series in Textiles: Number 164 Denim, Manufacture, Finishing and Applications , ed. Roshan, P., Elsevier, Cambridge UK, 2015, Section 3.7, which is hereby incorporated by reference. For instance, in some embodiments, the indigo is reduced to Leuco indigo using sodium hydrosulphite, hydroxy acetone, acetoin, glutaroin, adipoin, and/or a-hydroxybarbonyls. In some embodiments, the indigo is reduced to Leuco indigo using a combination of glucose and NaOH. In some embodiments, the indigo is reduced to Leuco indigo using thiourea dioxide, formamidmesulphhamic acid. In some embodiments, the indigo is reduced to Leuco indigo using iron(II) salt complexed with tartaric acid, citric acid or triethanolamine along with NaOH.

[0043] As used herein, the term “grit” refers to the abrasive properties of a surface. For example, a lower grit number (e.g., grit 40) refers to a coarse, more abrasive surface and a higher grit number (e.g., grit 1000) refers to a fine, less abrasive surface. An abrasive surface can be produced by adhering grit particles to the surface (e.g., the surface is coated with grit particles of a predetermined size at a predetermined density, where the predetermined size and density of the particles define the grit value of the surface). Typically, particles of a higher predetermined size result in a lower grit number (e.g., the density of particles on the surface will necessarily be lower) and particles of a smaller predetermined size results in a higher grit value (e.g., a higher density of particles can be fit onto the surface). In some embodiments, grit particles comprise aluminum oxide, garnet, emery, silicon carbide, aluminum-zirconia, chromium(III) oxide, ceramic aluminum oxide, diamond, or a combination thereof. As used herein, grit numbers are given in units of FEPA-F.

[0044] As used herein, the term “abrade” or “abrasion” refers to removing dye molecules from textile fibers. For example, Figure 1 A represents cross-sections of a dyed fiber 102 before and after abrasion 108 performed in accordance with embodiments described herein. Prior to abrasion, fiber 102 has a mostly uniform coating of dye 104 (e.g., a layer of indigo dye adhered to the fiber material). After abrasion (e.g., after exposure to one or more diamond sanding boards), the dye layer 106 is non-uniform (e.g., has been ‘nicked’ at multiple locations). The diameter and extent of the abrasion of the dye layer determines the extent of the color fade in the prewashed fabric (e.g., higher abrasion results in more color fade). Figure IB illustrates an example of abrading a fabric 110 using one or more sanding boards 112. In some embodiments, each respective sanding board of the one or more sanding boards (e.g., sanding boards 112a-l 12d) is electroplated with diamond at a specified grit (e.g., grit particles 114). In some embodiments, each respective sanding board of the one or more sanding boards has the same grit. In some embodiments, a subset of the sanding boards has a different unique grit (e.g., sanding board 112a may have a different grit from that of sanding board 112d). [0045] As used herein, a “twill weave” is a weave that is normally woven on four or more shafts. In a twill weave, each warp or weft yam floats over two or more weft or warp yams, with a progression of interlacing by one to the left or right, forming a distinct diagonal line as illustrated in Figure 5. Though a twill weave can be woven on three shafts, four or more shafts are normally used. Twill weave have a technical face and back cloth; the face is the side that shows the pronounced diagonal line. Twill weaves have two classifications, uneven or balanced. Uneven twills are those in which the warp comes to the surface to either a greater or lesser extent than does the weft. If the warp predominates on the face, the weave is called warp twill. If the filling predominates, it is called weft twill. Balanced twills are those in which the warp and weft come to the surface to the same extent. Because there are more weft yams than warp in twill-weave structures, the fabrics produced are heavier in with than plain-weave fabrics. As twill-weave fabrics have textured and patterned surfaces they are not often used for printed fabrics. Due to the strength of twill-weave fabrics, they are often used for work apparel or upholstery, as well as denim jeans. Fewer interlacings allow the yams to move freely and fabrics are more pliable, lustrous and softer than plain-weave fabrics; they also recover better from wrinkles than plain-weave fabrics see Textiles and Fashion Materials, Design and Technology, Rose Sinclair ed., Elsevier Ltd. 2015, Oxford UK, which is hereby incorporated by reference, including, in particular, pp. 273-274.

[0046] The terminology used herein is for describing particular cases only and is not limiting. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms “including,” “includes,” “having,” “has,” “with,” or variants thereof are used in either the detailed description and/or the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.”

[0047] Several aspects are described below with reference to example applications for illustration. It should be understood that numerous specific details, relationships, and methods are set forth to provide a full understanding of the features described herein. One having ordinary skill in the relevant art, however, will readily recognize that the features described herein can be practiced without one or more of the specific details or with other methods. The features described herein are not limited by the illustrated ordering of acts or events, as some acts can occur in different orders and/or concurrently with other acts or events. Furthermore, not all illustrated acts or events are required to implement a methodology in accordance with the features described herein. Exemplary Methods

[0048] Figure 2 illustrates an overview of the techniques in accordance with some embodiments of the present disclosure. In the described embodiments, a method for processing denim is provided.

[0049] Block 202. Referring to block 202, of Figure 2A, the present disclosure is directed to methods for processing denim.

[0050] Block 204-244. Referring to optional block 204, in some embodiments a yam comprising a plurality of textile fibers is dyed with a dye by coating a surface of the yam with the dye.

[0051] In some embodiments, the dye is blue. In some embodiments, the blue dye is indigo dye. In some embodiments, the blue dye is another type of dye (e.g., another shade of blue or another color than blue). Dyed yam prior to abrading is illustrated in Figure 3A, where individual fibers are heavily coated (e.g., are darker in appearance).

[0052] In some embodiments, the dyeing is optionally performed using foam indigo dye in the presence of nitrogen. For example, in some embodiments, any of the dyeing methods described in United States Patent No. US1061929, entitled “Indigo dyeing process and apparatus and indigo dyed yams and fabrics made thereby,” filed September 12, 2016, which is herein incorporated in its entirety, can be used to dye the yam comprising the plurality of textile fibers.

[0053] In some embodiments, rather than foam dyeing, conventional dyeing is used. In some embodiments, the dyeing is performed using an indigo rope range. In some such embodiments, the yam is in the form of ropes and between one and 48 ropes are dyed at one time. The dyeing at may be practiced using a wide variety of dyeing systems, such as vat, sulfur, reactive, napthol, padazoic, directs, and pigment, and are not limited to any one particular system. In some embodiments, the dyeing is performed using a Smartec rope dyeing machine such as the Smartec model LHJ3689.

[0054] The process of dyeing the yam with foam indigo dye or by conventional dyeing processes, as performed in accordance with some embodiments herein, results in a layer of indigo molecules coating textile fibers (e.g., as illustrated in Figure 1A).

[0055] In some embodiments, the use of foam dye enables the dye to adhere to fibers more efficiently (e.g., the fibers become coated with dye more quickly or easily). As described in United States Pat. No. US1061929, this can result in a thinner layer of dye, which makes downstream processes such as obtaining color fade easier. [0056] In some embodiments, the dye that is used is DyStar Indigo VAT 40% Solution (DyStar Singapore Pte Ltd., Singapore). See, the Internet dystar.com/denim-solutions/. This product has an Indigo concentration of 40% by weight and an alkali concentration of 9% by weight.

[0057] In some embodiments, the dye is an indigo dye or a sulphur dye, the plurality of textile fibers is natural fibers, regenerated fibers, or synthetic fibers, the plurality of textile fibers comprises cotton fibers. In some embodiments, the plurality of textile fibers comprises flax, kapok, hemp, jute, ramie, sisal, abaca, coir, or Pineapple fiber. In some embodiments, the plurality of textile fibers comprises rayon, polyester, polyamide, aramid, olefin, elastomer, or acrylic. In some embodiments, the plurality of textile fibers comprises elastic polyurethane fibers. In some embodiments, the plurality of textile fibers comprises stable fibers, filaments, or tow. In some embodiments, the plurality of textile fibers is round, dog bone shaped, trilobal, multilobal, serrated, band, triangular, oval, or hollow shaped. In some embodiments, the plurality of textile fibers is blended fibers. In some embodiments, the plurality of textile fibers is cotton blended with lycra, polyester, lyocell, wool, flax, or hemp. In some embodiments, the plurality of textile fibers comprises Gossypium hirsutum cotton, Gossypium barbadense cotton, Gossypium arboreum cotton, or Gossypium herbaceum cotton.

[0058] In some embodiments, the plurality of textile fibers have a length in the range of 10- 65 mm, a fitness in the range of 1.2 - 2.8 dtex, a dry tenacity in the range of 1.9 - 3.1 cN/dtex, a dry breaking extension in the range of 7 percent to 10 percent, a moisture regain of about 8.5 percent, and/or a density of 1.5 to 1.54 g/cm ³ . In some embodiments, the plurality of textile fibers has a minimum stable length of 28 mm. In some embodiments, the yam is monofilament yam or multifilament yam. In some embodiments, the yam is staple yam or spun yam. In some embodiments, the yam is a denim warp yam having a count of between Ne 4.0 and Ne 12.5. In some embodiments, the yam is a denim warp yam having a count of between Ne 12.5 and Ne 30.0. In some embodiments, the yam is produced by ring spinning, compact spinning, or rotor spinning.

[0059] In some embodiments, with regard to block 208, the plurality of textile fibers comprises natural fibers, regenerated fibers, synthetic fibers, or some combination thereof. In some embodiments, the plurality of textile fibers comprises cotton fibers. In some embodiments, the plurality of textile fibers consists of cotton fibers. In some embodiments, the plurality of textile fibers comprises flax, kapok, hemp, jute, ramie, sisal, abaca, coir, Pineapple fiber, or some combination thereof. In some embodiments, the plurality of textile fibers comprises rayon, polyester, polyamide, aramid, olefin, elastomer, acrylic, or some combination thereof. In some embodiments, the plurality of textile fibers comprises elastic polyurethane fibers. In some embodiments, the plurality of textile fibers comprises stable fibers, filaments, tow, or some combination thereof. In some embodiments, the plurality of textile fibers is round, dog bone shaped, trilobal, multilobal, serrated, band, triangular, oval, or hollow shaped. In some embodiments, the plurality of textile fibers is blended fibers. [0060] In some embodiments, dying of the yam is performed using rope, slasher or loop dyeing methods. In some embodiments, the yam is dyed using a solution that has an indigo concentration of between 1.2 percent and 5 percent. In some embodiments the yam is dyed in the presence of caustic soda and sodium hydrosulphite. In some embodiments, the dying process, with the indigo first being reduced to soluble Leuco indigo and exposed to the yam and then oxidized back to the original insoluble form, being repeated several times to obtain the desired shade. In some embodiments, such dying takes place in fermentation vats, chemical vats, or hydrosulphite vats.

[0061] In some embodiments, the dying of the yam with indigo is done using a continuous yam dyeing technique. In some embodiments, the article of clothing to be manufactured is to be made out of denim that is 100% cotton with a blue face and white back, in which the warp yams of the fabric are indigo dyed and the weft yams are non-dyed cotton.

[0062] In some such embodiments, the dyeing of the warp yams of the fabric is done continuously using rope dyeing, slasher dyeing, or loop dyeing. See, Section 4.3.2 of Woodhead Publishing Series in Textiles: Number 164 Denim, Manufacture, Finishing and Applications, ed. Roshan, P., Elsevier, Cambridge UK, 2015, which is hereby incorporated by reference.

[0063] In an exemplary rope dyeing technique, 350-400 warp threads are bound on a ball- warper machine to very thick cables of 10,000 - 25,000m in length or greater. Generally 12- 36 such cables are fed into a scouring bath containing wetting agents, detergents and sodium hydroxide. The scouring baths are used to remove impurities such as dirt, naturally occurring wases, etc. Then the cables are fed into one or more water rising baths. After that the cables are dipped into a bath of leuco indigo with an immersion time of 12-20 seconds, and then are squeezed to give up 79%-80% wet pick-up after each dip, followed by exposure to air (e.g., at least 80 seconds) for oxidation, multiple times. The cables of yam are then washed in water baths to eliminate non-fixed dye. Example rope ranges suitable for rope dying are made by Morrison Textile Machinery, USA (e.g., Spectrum Indigo Rope Dye Range), Master S.r.L, Italy, (e.g., IndigoRope), Karl Mayer Textilmashinefabrik GmbH, Germany (e.g., Indig-O- Matic IOM-R), Looptex Company, Italy (e.g., Rope Dye), Komatsubara Iron Works Ltd., Japan, and Smartec Machinery & Engineering, China (e.g., Model LHJ3689).

[0064] In an exemplary slasher dyeing technique, section beams of warp yam are forced into a sheet of yams (approximately 3000 - 5000 yams), which is first fed into a scouring section to remove natural impurities. Then the sheet passes through multi-dip/nip indigo dyeing section with an immersion time of 4-15 seconds in order to achieve fairly deep shades followed by oxidation for at least 45 seconds. After, rinsing and sizing, the warp sheet is directly processed and then sent to a weaving section for conversion to fabric. Example slasher dyeing machines suitable for slasher dying are made by Morrison Textile Machinery, USA, Master S.r.l., Italy, (e.g., IndigoFlow, and IndigoGenius); Karl Mayer Textilmashinefabrik GmbH, Germany (e.g., Indig-O-Matic IOM-S); Looptex Company,

Italy; Benninger AG, Switzerland (e.g., Ben-Indigo); Texima S.A. Industria de Maquinas, Brazil (e.g., Multicaixas slasher dyeing machine); Memnum Makina, Turkey; and Jupiter Comtex Pvt Ltd., India.

[0065] In an exemplary loop dyeing technique, the yams are dyed in only a single dyeing bath with one squeezing unit, after passing through pre-treatment boxes. When the yams exit the dyeing bath, instead of moving forward, the yams are passed back into the dye bath for another dye passage in a continuous loop. According to the desired shade, the yams can make multiple loops through the dye bath, after which they are passed through wash boxes and then onto drying cylinders. The loop dyeing technique is offered in machines sold by Looptex, under the Loopdye brand.

[0072] Blocks 262-264. Referring to block 262 of Figure 2D, in some embodiments the yam is weaved to form the initial fabric. Referring to block 264, in some embodiments, the method further comprises washing and drying the yam after the dyeing and before the weaving (block 262) or abrading (block 266).

[0073] In some embodiments, prior to the abrading disclosed below in conjunction with block 266, the method comprises dyeing the yam comprising a plurality of textile fibers with a blue dye by coating a surface of the yam with the blue dye, and weaving the yam to form the initial fabric. In some embodiments, the initial fabric is a 3x1 (3 warp threads for every weft thread) twill weave. In some embodiments, the initial fabric is a 2x1 (2 warp threads for every weft thread) twill weave. In some embodiments, the initial fabric is a plain (one warp thread for every weft thread) weave. In some embodiments, the initial fabric is over 9 Oz per square yard, over 9.5 Oz per square yard, over 10.0 Oz per square yard, or over 10.5 Oz per square yard.

[0074] Blocks 266-274. Referring to block 266 of Figure 2E, an initial fabric (e.g., a dyed fabric, as illustrated in Figure 3A) is abraded by passing the initial fabric through an abrader at a first predetermined speed, thereby obtaining a pre-washed fabric with an abraded texture. The abrader comprises one or more sanding boards (e.g., diamond sanding boards). Each respective sanding board in the one or more sanding boards has a respective surface (e.g., face) that contacts the initial fabric while spinning about a respective axis at a respective center of the respective sanding board during the abrading. In some embodiments, the abrader is a MATCHPOINT GMB diamondTec finishing machine. See, https://www.matchpoint-textile.com/english/diamondtec/, which is hereby incorporated by reference. Figure 9, similar to Figure IB, is a schematic of the MATCHPOINT abrader 900. The abrader 900 comprises a plurality of sanding boards (e.g., sanding boards 902-1, 902-2, 902-3, and 902-4). More or fewer sanding boards could be used for the abrader. In the case of abrader 900 of Figure 9, the one or more sanding boards is four slat rolls 902. Each respective slat roll in the plurality of rolls spins clockwise or counterclockwise with respect to the direction the fabric is passing. In Figure 9, the fabric direction (first direction) is indicated as traveling from left to right. In the abrader, the spin of each sanding board 902 is independent of the spin of all other sanding boards. Thus, for instance, sanding board 902-1 could spin with the fabric direction (clockwise) while, at the same time, sanding board 902-2 could spin against the fabric direction (counter-clockwise). The spin of a respective sanding board 902 causes the diamond encrusted outer surface of the respective sanding board 902 to rub against the fabric. For instance, referring to Figure 9, the clockwise or counterclockwise spin of sanding board 902-1 causes each the diamond encrusted slats 912 of the sanding board to contact the fabric. In some embodiments, each sanding board of the abrader is a slat roller as illustrated in Figure 9 and 10A. In some embodiments, each sanding board of the abrader is a cylinder roller as illustrated in Figures IB and 10B.

[0075] As further illustrated in Figure 9, the abrader 900 further comprises a plurality of contact rolls 906 that push the fabric against the sanding boards 902 at a predetermined pressure. With reference to block 270, in some embodiments, the pressure applied by each contact roll 906 is between 5 and 60 Kg/cm. In some embodiments, the pressure applied by each contact roll 906 is between 1 and 100 Kg/cm. In some embodiments, the pressure applied by each contact roll 906 is different. In some embodiments, the pressure applied by each contact roll 906 is the same.

[0076] As further illustrated in Figure 9, tension is applied against the fabric by using a pair of double transport rollers 914 are used to control the tension on the fabric while it is being abraded with the sanding boards 902.

[0077] In some embodiments, the abrading affects the amount of dye adhering to fibers in the initial fabric (e.g., as shown in Figure 3B, less dye is present - the fibers appear lighter than in Figure 3A). For example, Figure 3C, which is a zoomed-in version of Figure 3B, illustrates portions of the initial fabric (e.g., 352 and 354) that appear to have had dye mostly or completely removed.

[0078] In some embodiments, each respective sanding board in the one or more sanding boards spins about the respective axis (e.g., cylindrical axis) of the respective sanding board at the respective center of the respective sanding board at a rate of between 1000 and 3000 revolutions per minute. In some embodiments, each respective sanding board in the one or more sanding boards spins about the respective axis of the respective sanding board at the respective center of the respective sanding board at a rate of between 200 and 2000 revolutions per minute. In some embodiments, each respective sanding board in the one or more diamond sanding boards spins about the respective axis of the respective sanding boar at the respective center of the respective sanding board at a rate of between 1700 and 1900 revolutions per minute.

In some embodiments, each respective sanding board in the one or more sanding boards spins about the respective axis of the respective sanding board at the respective center of the respective sanding board at a constant rate. In some embodiments, each respective sanding board in the one or more diamond boards spins about the respective axis of the respective sanding board at the respective center of the respective sanding board at a variable rate.

[0086] Block 288. Referring to block 216 of Figure 2F, in some embodiments the method proceeds by washing the fabric with an ozone composition, thereby obtaining an ozone washed fabric. In some embodiments, ozone washing the pre-washed fabric comprises applying ozone to the pre-washed fabric in an enclosed container with rotary motion (e.g., a washing machine). In some embodiments, the ozone washing can be performed for example as described in JP Patent Application No. JP2005295193, filed on October, 2005, entitled “Cloth drier, washing machine, and washing machine with cloth drying function” which is hereby incorporated by reference in its entirety. In some embodiments, the ozone washing machine is a Jeanologia G2 Dynamic 200 or G2 Dynamic 235 ozone washing machine. See, for example, https://www.jeanologia.com/portfolio/g2-dynamic/, which is hereby incorporated by reference.

[0087] Referring to block 290, in some embodiments, the ozone washed fabric is denim. In some embodiments, the ozone washed fabric is another type of fabric.

[0088] Referring to block 292, in some embodiments, the ozone composition (e.g., for use in ozone washing) is between 5 g/Nm ³ ozone and 100 g/Nm ³ ozone. In some embodiments, the ozone composition is between 5 g/Nm ³ ozone and 50 g/Nm ³ ozone. In some embodiments, the ozone composition is between 5 g/Nm ³ ozone and 20 g/Nm ³ ozone. In some embodiments, the ozone composition is between 10 g/Nm ³ ozone and 20 g/Nm ³ ozone. [0089] Referring to block 294 of Figure 2F, in some embodiments the fabric has a width of between 40 centimeters and 400 centimeters. In some embodiments the fabric has a width of between 40 centimeters and 200 centimeters. In some embodiments the fabric has a width of between 40 centimeters and 100 centimeters. In some embodiments, the fabric has a length of between 1 meter and 500 meters, between 2 meters and 400 meters, between 3 meters and 300 meters, between 4 meters and 200 meters, or between 5 meters and 100 meters. In some embodiments, the fabric has a width of between 40 centimeters and 400 centimeters and a length of between 1 meter and 500 meters.

[0090] In some embodiments, the washed fabric has a width of between 80 centimeters and 400 centimeters. In some embodiments, the washed fabric has a width of between 80 centimeters and 200 centimeters. In some embodiments, the washed fabric has a width of between 100 centimeters and 200 centimeters. In some embodiments, the washed fabric has a width of between 40 centimeters and 400 centimeters. In some embodiments, the washed fabric has a width of between 40 centimeters and 100 centimeters. In some embodiments, the washed fabric has a width of between 40 centimeters and 80 centimeters.

[0091] Referring to block 298 of Figure 2G, in some embodiments, the ozone washed fabric has a length of at least 50 meters.

[0092] Referring to block 300 of Figure 2G, in some embodiments, the ozone washed fabric has a length of at least 100 meters.

[0093] In some embodiments, the washed fabric has a length of at least 50 meters. In some embodiments, the washed fabric has a length of at least 100 meters. In some embodiments, the washed fabric has a length of at least 10 meters, at least 20 meters, at least 30 meters, at least 40 meters, at least 50 meters, at least 60 meters, at least 70 meters, at least 80 meters, at least 90 meters, at least 100 meters, at least 150 meters, at least 200 meters, at least 300 meters, at least 400 meters, or at least 500 meters.

[0094] Referring to block 302 of Figure 2G, in some embodiments, abrading and washing cause the pre-washed fabric to exhibit a predetermined amount of color fade relative to the initial fabric. In some embodiments, the specified grit for the surface of each sanding board in the one or more sanding boards is varied to produce differing amounts of color fade in the ozone washed fabric relative to the initial fabric. In some embodiments, the specified grit value is inversely proportional to the predetermined amount of color fade (e.g., a higher specified grit value causes a lower amount of color fade relative to the initial fabric).

[0095] In some embodiments (e.g., where the yam comprising the plurality of textile fibers has been dyed with indigo dye), the predetermined amount of color fade causes the washed fabric to be one of dark indigo, medium indigo, or light indigo. In some embodiments, with reference to block 304 of Figure 2G, the predetermined amount of color fade causes the washed fabric to have a CIELab L* value that is between 8 and 49, a CIELab a* value that is between -1.4 and 3.5, and a CIELab b* value that is between -10.50 and -1.20. Under the CIELab coordinate system, L* represents the degree of lightness. The attribute a* indicates the degree of redness and greenness (when a* increases, the redness of the sample increases, and vice versa). The attribute b* indicates the degree of yellowness and blueness (when b* increases, the yellowness increases, and vice versa). In some embodiments, the predetermined amount of color fade causes the washed fabric to have a CIELab L* value that is between 35 and 43, a CIELab a* value that is between -1.4 and 3.5, and a CIELab b* value that is between -10.50 and -6.00.

[0096] In some embodiments, other amounts of color fade are obtained (e.g., intermediate shades of color fade such as medium-dark indigo, medium-light indigo, etc.). In some embodiments (e.g., where the yam has been dyed at least in part with indigo dye), the predetermined amount of color fade causes the washed fabric to be one of dark intensity, medium intensity, or light intensity.

[0097] Blocks 306-312. Referring to block 306 of Figure 2G, the method optionally proceeds by using the washed fabric to produce the article of clothing. Referring to block 308, in some embodiments, using the ozone washed fabric to produce the article of clothing comprises cutting, making, and trimming with the ozone washed fabric to form the article of clothing. Referring to block 310, in some embodiments, the article of clothing is a pair of denim jeans. Referring to block 312, in some embodiments, the article of clothing is a denim shirt, a denim dress, a denim skirt, or a denim handbag. In some embodiments, the article of clothing is any article of clothing known in the art.

[0098] Block 314-316. With reference to block 314 of Figure 2H, in some optional embodiments, the method further comprises agitation washing the article of clothing. In some embodiments, agitation washing the article of clothing serves to remove any impurities or dirt accumulated during the previous steps in the manufacturing process. With reference to block 316, in some embodiments, the agitation washing of the article of clothing comprises a sonic washing in a water bath.

[0099] Block 318. With reference to block 318 of Figure 2H, in some the method optionally comprising drying the article of clothing.

[00100] Blocks 320-324. In some embodiments, the method further comprises patterning the article of clothing with a laser to produce one or more laser designs within the article of clothing. In some embodiments, the one or more laser designs within the article of clothing comprise distressed or wom-out effects. In some embodiments, the patterning is done before the agitation washing of the article of clothing. In some embodiments, the patterning is done after the agitation washing and the drying of the article of clothing (e.g., this is important for articles of clothing with high amounts of patterning - e.g., many wom-out effects). In some embodiments, a Jeanologia Flexi Pro, Twin Pro, or Compact is used to perform such patterning. EXAMPLES

[00101] Example 1. In this example, methods for processing denim fabric are described. In these examples, an initial fabric is abraded by passing the initial fabric through an NB- MATCHPOINT GMB diamondTec finishing machine. In so doing, the initial fabric is abraded into a pre-washed fabric with an abraded texture. For Example 1, three denim fabrics were selected. Abrading data for the three denim fabrics is detailed below in Tables 1, 2, and 3. As detailed in these tables, for each respective fabric of the three selected fabrics, four samples of the respective fabric were used. For three of the four samples of a respective fabric, different levels of fabric abrasion were performed on the samples with a NB- MATCHPOINT GMB diamondTec finishing machine, while the fourth sample of the respective fabric was retained with no abrasion as a reference standard control.

[00102] The NB-MATCHPOINT GMB diamondTec finishing machine settings are indicated in Tables 1, 2 and 3 below with speeds, pressures and direction of the peacher rollers. In these tables, DP2 stands for 220 diamondpeach grit, DP4 stands for 400 diamondpeach grit, and DP6 stands for 600 diamondpeach grit.

[00103] Figure 9 provides a schematic diagram of the NB-MATCHPOINT GMB diamondTec abrader 900 for purposes of identifying sanding boards (902-1), 2 (902-2), 3 (902-3), and 4 (902-4), contact roller 1 (906-1), contact roller 2 (906-2), the fabric (910) that is being abraded, and the double transport rollers 914. Further in these tables, and referring to Figure 9, machine speed, in units of meters/minute, is the speed at which fabric 910 is passing through the abrader 900. Further in these tables, grit 1 is the grit value of sanding board 902-1, grit 2 is the grit value of sanding board 902-2, grit 3 is the grit value of sanding board 902-3, and grit 4 is the grit value of sanding board 902-4. Further in these tables, RPM of roll 1 is the revolutions per minute of sanding board 902-1, RPM of roll 2 is the revolutions per minute of sanding board 902-2, RPM of roll 3 is the revolutions per minute of sanding board 902-3, and RPM of roll 4 is the revolutions per minute of sanding board 902-4. Further in these tables, the roller direction 1 through 4 indicate whether each respective sanding board 902 is rotating clockwise (with the direction of the fabric) or counterclockwise (against the direction of the fabric) from the perspective of Figure 9. In Tables 1 through 3, “CO” stands for cotton, and “EL” stands for elastane, and “PEL” stands for polyester. [00104] Table 1 - Denim Fabric One

[00105] Table 2 - Denim Fabric Two

[00106] Table 3 - Denim Fabric Three

[00107] All fabrics were then all treated with Jeanologia G2 dynamic ozone to remove loose indigo at a rate of 40m/min - 5g of ozone. All fabrics were then sewn into pant leg form as illustrated in Figure 6. Figure 6 illustrates how the coupling of abrasion followed by ozone washing creates denim that looks like it has been processed in garment laundry but has now been created in the fabric form. In Figure 6, the fabrics running with line 602-1 correspond to fabric one of Table 1, where the individual samples of fabric 1 are labeled. In Figure 6, the fabrics running with line 602-2 correspond to fabric two of Table 2, where the individual samples of fabric 2 are labeled. In Figure 6, the fabrics running with line 602-3 correspond to fabric three of Table 3, where the individual samples of fabric 3 are labeled. For each sample, there are two pant legs illustrated in Figure 6, a left hand one and right hand one, which have been subjected to the same treatment.

[00108] Example 2. This example illustrates garment trials with and without fabric abrasion. [00109] Figure 7 illustrates an unwashed garment that has not been subjected to fabric abrasion (left) and an unwashed garment that has been subjected to fabric abrasion (right). [00110] To produce the garment on the right of Figure 7, in this example, a denim initial fabric was abraded by passing the initial denim fabric through an NB-MATCHPOINT GMB diamondTec finishing machine. In so doing, the initial fabric is abraded into a pre-washed fabric with an abraded texture. The NB-MATCHPOINT GMB diamondTec settings for the machine are indicated in Tables 4 below with speeds, pressures and direction of rollers.

[00111] Table 4 - Denim Fabric Four

[00112] The denim was then treated with a Jeanologia G2 dynamic ozone washer to remove loose indigo using 20 g / Nm ³ of ozone. The denim was then sewn into the garment illustrated in the right panel of Figure 7. The left hand garment and the right hand garment of Figure 7 were then washed to produce the respective left-hand garment (not abraded) and right-hand garment (pre-abraded) of Figure 8. As is evident in Figure 8, there is a substantial difference in the fading. The pre-abraded fabric washes down faster.
