  The present invention relates to a woven fabric, particularly a woven fabric comprising poly (ethylene terephthalate) and poly (trimethylene terephthalate) polyester composite filaments stretched in the warp direction of the woven fabric and optionally in the weft direction.

  In general, polyester composite fibers containing poly (ethylene terephthalate) and poly (trimethylene terephthalate) are known. Such fibers are disclosed in, for example, US Patent Publication (Patent Document 1), and now in US Patent Publication (Patent Document 2). Such fibers are disclosed in U.S. Patent Publication (Patent Document 3) and (Patent Document 4), (Patent Document 5), (Patent Document 6), (Patent Document 7), (Patent Document 8), and (Patent Document 9). It has been used for woven fabrics as disclosed. However, such fabrics have a high proportion of polyester composite fibers and there is a need for fabrics that utilize such fibers more efficiently.

US Patent Application Publication No. 2001/0055683 US Pat. No. 6,803,000 B2 US Patent Application Publication No. 2003/0092339 JP 2002-004145 A JP 2001-303394 A JP 11-172545 A JP 2001-316923 A JP 2002-180354 A JP 2002-1555449 A

  The present invention relates to warp stretch woven fabrics of plain weave, twill weave or satin weave structures. The woven fabric has weft and warp, and about 15 to about 55 weight percent of the warp is a polyester composite continuous filament containing poly (ethylene terephthalate) and poly (trimethylene terephthalate). The polyester composite warp yarn preferably has a crimp shrinkage value after heat setting of about 20% to about 80%.

  It has now been found that warp-stretched woven fabrics can be made with surprisingly high extensibility and recoverability despite the inclusion of a relatively low level of certain polyester composite yarns.

(Definition)
As used herein, a “polyester composite filament” is a filament cross-section such that the filament cross-section is, for example, side-by-side, eccentric sheath-core, or other suitable cross-section from which useful crimps can grow. By means of a continuous filament comprising two different polyesters closely bonded together along their length. “Yarn” means a plurality of continuous filaments. “Pick-and-pick” means a woven structure in which polyester composite filament weft yarns (“first yarn”) and (“second”) weft yarns are in alternating picks of fabric. “Co-insertion” means a woven structure in which polyester composite filament yarns (“first yarn”) and (“second”) weft yarns are woven together as one on the same pick. “Separately woven” means that the yarns are separated from each other within the finished fabric without being twisted or entangled before being woven, and as used herein “separately woven” Does not exclude the weaving into a weaving collection or co-insert structure of substantially similar filaments (optionally interlaced with each other).

  As used herein, “spandex” means an artificial filament in which the filament forming material is a long chain synthetic polymer comprising at least 85% by weight segmented polyurethaneurea.

  As used herein, “elastoester” means an artificial filament whose fiber-forming material is a long-chain synthetic polymer consisting of at least 50% by weight aliphatic polyether and at least 35% by weight polyester.

  As used herein, “lastol” is a low but significant degree of crystallinity crosslinked synthetic polymer fiber. The polymer is a metallocene-based polyolefin containing at least 95% by weight ethylene and at least one other olefin unit. This fiber is elastic and substantially heat resistant.

  The fabric of some embodiments is a warp stretch woven fabric selected from the group consisting of plain weave, twill, and satin weave structures. The warp stretch fabric has weft and warp. The warp yarn is about 10 to about 60 weight percent poly (ethylene terephthalate) and poly (trimethylene terephthalate), and about 5 to about 60 weight percent, including about 15 to about 55 weight percent and about 22 to about 33 weight percent. Polyester composite continuous filaments may be included, including in percent amounts. Other warp yarns can be, for example, spun staple yarns such as cotton, wool, or linen, which are also monocomponent poly (ethylene terephthalate) fibers, monocomponent poly (trimethylene terephthalate) fibers, polycaprolactam fibers, It can also be of poly (hexamethylene adipamide) fiber, acrylic fiber, modacrylic fiber, acetate fiber, rayon fiber, and combinations thereof.

  The weft thread can be the same as or different from the warp thread. The fabric can only be warp stretch, or it can be both stretchable with useful stretchability and recovery shown in both the warp and weft directions, such weft stretch is a polyester composite filament yarn , Spandex, melt spun elastomers and the like. When the weft yarn comprises a polyester composite filament ("first") yarn, they are present together with a second yarn (optionally spun staple yarn), for example, in a pick-and-pick or co-insertion structure Can do.

  The composite filament yarn may be in any desired amount, eg, about 13 to about 70% when the polyester composite filament is not present in the weft yarn (ie, when the polyester composite filament is only present in the warp yarn), based on the total fabric weight. About 10 to about 30 weight percent can be present, including about 28 weight percent and about 13 to about 19 weight percent. When composite filaments are present in both warp and weft yarns, the composite filament yarns may be present in higher amounts, for example from about 10 to about 60 weight percent, including from about 20 to about 40 weight percent.

  The polyester composite filament comprises poly (ethylene terephthalate) and poly (trimethylene terephthalate) in a weight ratio of about 30/70 to about 70/30, about 20% to about 80%, preferably about 30% to about 60%. It has a crimp shrinkage value after heat setting. Various comonomers can be incorporated into the polyester of the composite filament in small amounts, provided that such comonomers do not adversely affect the amount of fiber crimp and if the benefits of the present invention are not adversely affected. Examples include linear, cyclic, and branched aliphatic dicarboxylic acids (and their diesters) having 4 to 12 carbon atoms; aromatic dicarboxylic acids (and their diesters) having 8 to 12 carbon atoms ) (Eg, isophthalic acid, 2,6-naphthalenedicarboxylic acid, and sodium 5-sulfoisophthalate); and linear, cyclic, and branched aliphatic diols having 3-8 carbon atoms (eg, 1,3- Propanediol, 1,2-propanediol, 1,4-butanediol, 3-methyl-1,5-pentanediol, 2,2-dimethyl-1,3-propanediol, 2-methyl-1,3-propane Diol, and 1,4-cyclohexanediol). Isophthalic acid, pentanedioic acid, sodium 5-sulfoisophthalate, hexanedioic acid, 1,3-propanediol, and 1,4-butanediol are preferred. Polyesters can also incorporate additives such as titanium dioxide therein.

  The linear density of the polyester composite filament yarn from which some embodiments of fabrics are made includes about 10 denier to about 900 denier (including 78 decitex to about 500 decitex, including about 70 denier to about 450 denier). Range from 11 dtex to about 1000 dtex).

  In some embodiments, the polyester composite filament yarn is not a twisted or intertwined combination of the composite filament and other, eg, monocomponent or staple fibers. In other words, in these embodiments, the composite filament yarn has high extensibility and resiliency, and provides high fabric surface smoothness, so as to avoid the cost of additional steps and other yarns in the fabric. May be woven separately.

  In other embodiments, the polyester composite filaments may be twisted, entangled, or core-spun with other fibers or filaments to provide additional beneficial properties. These properties include reducing the exposure of the composite filament and providing a different look to the fabric. In these embodiments, multicomponent yarns may be produced that comprise polyester composite filaments in addition to staples, continuous filaments, and optionally other fibers or filaments that may be textured fibers. These other fibers or filaments include relatively inelastic yarns and optionally cotton, polyester, nylon, rayon and wool as well as elastic yarns such as rubber filaments, composites and elastomeric esters, lasttle and spandex It is also called a hard thread.

  Multicomponent yarns may also include coated yarns in which one fiber is surrounded, twisted or mixed with another fiber or yarn. Coated yarn comprising elastic fibers and hard yarn is also referred to as “composite yarn”. When elastic fibers are used, a hard yarn coating helps to protect the elastic fibers from abrasion during the weaving process. Such wear can result in breakage of the elastic fibers with consequent process interruptions and undesirable fabric non-uniformities. Furthermore, the coating helps to stabilize the elastic fiber elastic behavior, so that the composite yarn elongation can be controlled throughout the weaving process more uniformly than would be possible with bare elastic fibers.

  (A) Single wrapping of one fiber with different fibers, (b) Double wrapping of one fiber with another fiber, (c) Continuous coating of one fiber with staple fibers (ie, core spinning), and subsequent winding Various types of composite yarns, including: (d) mixing and entanglement of two or more fibers with an air jet, and (e) twisting together two or more different fibers or yarns There is. An example of a composite yarn is a core span yarn. “Core spun yarn” consists of a separable core surrounded by a spun fiber sheath. The elastic core spun yarn is produced by introducing an elastic filament into the spinning machine's front draw roller, where it is coated with staple fibers.

  Many combinations of composite polyesters with elastic and / or hard yarns may be included. For example, composite polyester filaments may be combined with one or more hard yarns without additional elastic fibers. Alternatively, the composite polyester may be combined with one or more elastic fibers, and optionally also with one or more hard yarns. The elastic filaments may be present in an amount of zero to about 50% by weight, either warp or weft, including about 1% to about 10% by weight.

  In embodiments that include additional elastic fibers, a lower weight percentage of the composite polyester may be necessary to achieve the desired stretch recovery for fabrics containing these multicomponent yarns. Suitable fabrics may include multicomponent yarns having composite filaments and one or more elastic filaments. In these multicomponent yarn-containing fabrics, the polyester composite filaments are from about 3% to about 55%, from about 5% to about 33%, from about 5% to about 25%, based on the weight of the warp. It may be present from about 1% to about 60% by weight, including weight percent, and from about 10% to about 25% by weight. For fabrics containing multicomponent yarns containing polyester composites, the polyester composite filaments are about 1 based on the total fabric weight (including when the composite polyester filament is present only in the warp or in the warp and weft). Weight percent to about 35 weight percent, about 5 weight percent to about 28 weight percent, about 13 weight percent to about 28 weight percent, about 13 weight percent to about 19 weight percent, and about 8 weight percent to about 20 weight percent. And may be present in an amount of from about 0.5% to about 50% by weight.

  In some embodiments, up to about 3% by weight of resin or similar material is present in or added to the fabric. This is because such resin treatment can add cost and the benefits of the present invention are achieved without incurring this cost. Another benefit of the present invention is that the polyester in the composite filament does not need to be partially removed from the fabric by chemical means, for example by application of a chemical treatment such as a highly alkaline solution. Although such resins and chemical treatments may still be used in connection with the present invention, the inventors may impair the extensibility and recoverability of the woven fabric and are therefore preferred to eliminate such additional steps. I think. However, additional materials such as resins may be added in any desired amount to achieve additional benefits.

  The fabric of some embodiments can be of a plain weave, twill or satin weave structure. Examples of useful twill structures include regular twills (eg, 2/1, 1/2, 1/3, and 2/2 twills), modified twills (to which additional lifts have been added to the weaving plan), Examples include herringbone and Yamagata syllabary. Examples of useful satin weave structures include 5 end (eg 1/5 and 2/5) and 8 end (eg 3/8) weaves.

  Some embodiments of the fabric are useful for a variety of end uses. These include clothes and clothing such as pants, shirts, and jackets, including denim pants or jeans and jackets as well as for furniture.

  Loom types that can be used to produce woven fabrics include air jet looms, shuttle looms, water jet looms, rapier looms, and gripper (projectile) looms.

  Prior to testing, fabrics and fibers were acclimated for 16 hours at 21 ° C. ± 1 ° C. and 65% ± 2% relative humidity.

The shrinkage value after heat setting was measured as follows. A sample of composite polyester filaments to be used was skeined with 5000 ± 5 total denier (5550 dtex) on a skein reel at a tension of about 0.1 gpd (0.09 dN / tex). The skeins were acclimated for a minimum of 16 hours at 70 ± 2 ° F. (21 ± 1 ° C.) and 65 ± 2% relative humidity. The skein is suspended substantially vertically from the stand, and a 1.5 mg / denier (1.35 mg / dtex) weight (eg, 7.5 grams for 5550 dtex skein) is hung on the bottom of the skein and the weight is attached Was allowed to reach an equilibrium length and the skein length was measured to within 1 mm and recorded as “Cb”. The 1.35 mg / decitex weight was left on the skein for the duration of the test. A 500 gram weight (100 mg / d; 90 mg / dtex) was then hung from the bottom of the skein and the skein length was measured to within 1 mm and recorded as “Lb”. Crimp shrinkage value (percent) (before heat setting, as described below for this test), “CCb” is the formula:
CCb = 100 × (Lb−Cb) / Lb
Calculated according to

The 500 g weight is removed and the skein is then hung in the rack in an oven for 5 minutes at about 225 ° F. (107 ° C.) with the 1.35 mg / dtex weight still in place, heat set, then the rack and The skein was removed from the oven and allowed to acclimate for 2 hours as described above. This process is designed to simulate a commercial dry heat setting, which is one method for growing the final crimp in a composite fiber. The length of the skein was measured as described above and the length was recorded as “Ca”. A 500 gram weight was again suspended from the skein and the skein length was measured as described above and recorded as “La”. Crimp shrinkage value (%) after heat setting, “CCa” is the formula:
CCa = 100 × (La−Ca) / La
Calculated according to

In the examples, the Dornier rapier weaving machine is in the state of a loom with 55 picks per inch (22 picks / cm) plain weave and 62 picks per inch (24 picks / cm) 1/3 twill unless otherwise stated. Used at 500 picks per minute to make the fabric. Poly (ethylene terephthalate) and poly (trimethylene terephthalate) yarns (“composite polyester yarns”) are 150 denier (167 dtex), 34 filament T-400 ^™ Elasterell— p. The polyester composite filaments were 40 wt% poly (ethylene terephthalate) and 60 wt% poly (trimethylene terephthalate) and had a crimp shrinkage value after heat setting of 47%. Prior to rewinding, the composite fiber yarn to be used for warp yarn is made of poly (vinyl alcohol) using a Suzuki single-end sizing machine with a sizing treatment bath temperature set at 107 ° F (42 ° C). ) The sizing treatment was performed at 300 yards / minute (274 m / minute). The sized yarn was dried at 190 ° F. (88 ° C.) for about 5 minutes. The weft was 30 cotton count ring spun cotton. Poly (ethylene terephthalate) yarn ("one-component polyester yarn"), when used, is a textured and combined 150 denier (167 dtex), 50 filament yarn manufactured by Unifi, Inc. Met.

  Each fabric cloth is passed through hot water under low tension three times at 160 ° F., 180 ° F. and 202 ° F. (71 ° C., 82 ° C., and 94 ° C., respectively), then it is passed through 6 % By weight Synthazime® (starch hydrolase from Dooley Chemicals LLC), 1% by weight Lubit® 64 (manufactured by Sybron Inc.) Nonionic lubricants), and 0.5 wt% Merpol® LFH (surfactant and EI du Pont de Nemours and Company) Sizing) at 160 ° F. (71 ° C.) for 30 minutes. And rubbing washing, it was finished by subsequent addition of 0.5 wt% trisodium phosphate. The fabric is then scrubbed for 5 minutes at 110 ° F. (43 ° C.) with 1 wt% Rubit® 64 and 1 wt% Marpol® LFH, and yellow disperse dye (and cotton is present in the fabric) Sometimes with yellow reactive dyes), jet dyed at 230 ° F (110 ° C) for 30 minutes at pH 5.2, then at 340 ° F (171 ° C) while underfeeding in the warp direction with a tenter. Heat set for 40 seconds. (Weight percent for finishing ingredients is based on fabric weight.)

The percent available stretch of the fabric in the examples was measured as follows. Three 60 × 6.5 cm sample specimens were cut from each fabric. The long dimension corresponded to the warp direction. Each specimen was unwound equally on each side until it was 5 cm wide. One end of the fabric was folded to form a loop, and seams were sewn across the width to secure the loop. A first line was drawn 6.5 cm from the non-looped end of the fabric, and 50 cm away from the first line (“GL”), a second line was drawn. Samples were acclimated for at least 16 hours at 20 ± 2 ° C. and 65 ± 2% relative humidity. The sample was then secured at the first line and suspended vertically. A 30 Newton weight was hung from the loop, and the sample was alternately moved 3 times by it being stretched by the weight for 3 seconds and then supporting the weight so that the fabric was unloaded. The weight was reapplied and the distance between lines (“ML”) was recorded to the nearest millimeter. Percent available elongation is formula I,
% Available extension = 100 × (ML-GL) / GL (I)
And the results from 3 specimens were averaged.

The percent recovery of fabric in the examples was calculated as 100% minus percent fabric growth (% fabric elongation) measured as follows. Three new specimens were prepared as described for the available extension test, stretched to 80% of the previously measured available extension, and held in the stretched state for 30 minutes. They were then allowed to relax for 60 minutes without restriction, and the length between lines (“L2”) was measured again. The percent fabric elongation is formula II,
% Fabric elongation = 100 × (L2-GL) / GL (II)
And the results from 3 specimens were averaged.

  In describing the warp repeating pattern in the fabric structure of the example, “bi” means composite and “mono” means one component. The repeating pattern used was the most uniform for the weight percentage of composite filament warp present. For example, when the composite filament yarn is at the 50 weight percent level, the repeating pattern is bi / mono / bi / mono rather than bi / bi / mono / mono, and the composite filament is present at the 33 weight percent level in the warp yarn. In this case, the repetitive pattern was bi / mono / mono / bi / mono / mono rather than bi / bi / mono / mono / mono / mono. Although the most uniform repeating pattern is used to obtain high fabric uniformity in terms of surface appearance, elongation, and recovery, such a pattern is not essential.

  The available stretch (“stretch”) and “recovery” properties of the fabrics produced in the examples are presented in Tables I (plain fabric) and II (twill fabric). For clarity, the yarns used in the examples had the same linear density so that the warp end percent was equal to the warp weight percent. In the table, “composite weight percent” is based on the total warp weight. “Elongation per composite weight percent” and “Recovery per composite weight percent” relate to the relative amount of composite polyester yarn in the warp yarn alone.

The fabric was 80 inches (203 cm) wide on the loom and 75 inches (190 cm) wide on the dough. After dyeing and finishing, the fabric has 31% and 18% available elongation, 94 end / inch (37 end / cm) and 102 pick / inch (40 pick / cm) yarn density, respectively, in the warp and weft direction. Had. The fabric weighed 5.64 ounces per square yard (191 g / m ² ) and contained 50% by weight composite polyester yarn based on the total fabric weight.

( Comparative Example 12 )
A plain woven fabric was produced in which the warp yarns were entirely composite polyester yarns, ie, the end ratio was 1: 0. The weft was 30cc ring spun cotton. A Ruti air jet loom was used at 500 picks per minute. On the loom, the yarn counts were 70 ends / inch (28 ends / cm) and 50 picks / inch (20 picks / cm). The fabric was 67 inches (170 cm) wide on the loom and 65 inches (165 cm) in the dough state. After dyeing and finishing, the fabric has a weight of 3.47 ounces / square yard (118 g / m ² ) and yarn densities of 74 ends / inch (29 ends / cm) and 72 picks / inch (28 picks / cm). It contained 54% by weight composite polyester yarn, based on the total fabric weight.
