STRAPCH WOVEN FABRICS COMPRISING POLYESTER BICOMPONENT FILAMENTS <br> <br> <br> Patents - stay tuned to the technology WARP-STRETCH WOVEN FABRICS COMPRISING POLYESTER BICOMPONENT FILAMENTS WIPO Patent Application WO /

The present invention relates to a woven fabric comprising polyester bicomponent filaments of a woven fabric, in particular of poly (ethylene terephthalate) and poly (trimethylene terephthalate) oriented in the oblique direction of the fabric.

Generally, polyester bicomponent fibers comprising poly (ethylene terephthalate) and poly (trimethylene terephthalate) are known. Such fibers are disclosed, for example, in U.S. Patent Application Publication No. US2001 / 0055683. Such fibers are disclosed in U.S. Patent Application Publication No. 2003/0092339 and Japanese Patent Application Laid-Open Nos. JP2002-004145, JP2001-303394, JP11-172545, JP2001-316923, JP2002-180354 And JP2002-1555449 (JP2002-1555449).

However, such fabrics may have a high proportion of polyester bicomponent fibers unnecessarily, and a fabric that makes more efficient use of such fibers is sought.

The present invention relates to a warp-woven, stretch-woven or stretch-woven warp-stretch fabric. The fabric is a polyester bicontinuous filament that has a weft and a warp, and about 15 to about 55 weight percent of the warp comprises poly (ethylene terephthalate) and poly (trimethylene terephthalate). The polyester bicomponent gradient preferably has a crimp shrinkage value after heat curing of from about 20% to about 80%.

It has now been found in the present invention that an incline-stretch fabric having unexpectedly high elongation and resilience can be produced despite the fact that it contains a relatively low concentration of the particular polyester heterogeneous jet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [

As used herein, "polyester bicomponent filaments" include a pair of polyesters that are intimately bonded to one another along the length of the filaments so that the filament cross-section can be formed, for example, , Eccentric sheath-core, or other suitable cross-section. "Yarn" means a number of continuous filaments. "Pick-and-pick" means a weaving structure in which polyester bicomponent filament wefts ("first yarn ") and (" second ") weft yarns are alternate picks of the fabric. By "co-inserting" is meant a weave structure in which polyester bicomponent filament yarns ("first yarn") and ("second") weft yarns are woven together in the same pick. "Separably woven" means that the yarns are separated from each other in the final fabric without being twisted or tangled together before they are woven; "Separably woven " herein does not exclude the weaving of a collection of substantially similar filaments (optionally intertwined with each other) or weaving into a co-inserted structure.

The fabric of the present invention is a warp direction-stretch fabric selected from the group consisting of plain, twilled, and junior. The slanting-extensible fabric has a weft and warp, wherein about 15 to about 55 weight percent (preferably about 22 to about 33 weight percent) of the warp is poly (ethylene terephthalate) and poly (trimethylene terephthalate) ). &Lt; / RTI &gt; Other warp yarns may be, for example, spun staple yarns, such as cotton, wool or linen; They may also include one or more of poly (ethylene terephthalate) fibers, monocomponent poly (trimethylene terephthalate) fibers, polycaprolactam fibers, poly (hexamethylene adipamide) fibers, acrylic fibers, modacrylic fibers, And combinations thereof.

The scissors can be the same as or different from the slope. The fabric may be merely slanted-extensible, or the useful extensibility and resilience may be anisotropic-extensible which occurs in both the slope and weft direction; Such weft direction-extensibility may be provided by polyester bicomponent filament yarns, spandex, melt-spun elastomers, and the like. If the weft comprises polyester bicomponent filaments ("first") yarns, they may be present in a second yarn (optionally spun staple yarn), for example in a pick-and-pick or cavity insert structure.

The bicomponent filament yarn may be present in an amount of from about 13 to about 28 weight percent based on the total fabric weight (when the polyester bicomponent filament is present in the warp yarn only) 13 to about 19% by weight).

The polyester bicomponent filaments include poly (ethylene terephthalate) and poly (trimethylene terephthalate) in a weight ratio of about 30/70 to about 70/30 and have a crimp shrinkage value after heat curing of about 20% to about 80% Preferably from about 30% to about 60%. If the comonomer does not adversely affect the amount of fiber crimp and the benefits of the present invention are not adversely affected, various comonomers may be incorporated into the polyester of the bicomponent filaments in small amounts. Examples include linear, cyclic and branched aliphatic dicarboxylic acids having 4 to 12 carbon atoms (and their diesters); Aromatic dicarboxylic acids having 8 to 12 carbon atoms (and esters thereof) (e.g., isophthalic acid, 2,6-naphthalene dicarboxylic acid and 5-sodium-sulfoisophthalic acid); And linear, cyclic and branched aliphatic diols having from 3 to 8 carbon atoms (e.g., 1,3-propanediol, 1,2-propanediol, 1,4-butanediol, 5-pentanediol, 2,2-dimethyl-1,3-propanediol, 2-methyl-1,3-propanediol and 1,4-cyclohexanediol). Isophthalic acid, pentane diacid, 5-sodium-sulfoisophthalic acid, hexane diacid, 1,3-propanediol and 1,4-butanediol are preferable. Additives such as titanium dioxide may also be incorporated into the polyester.

The linear density of the polyester bicomponent filament yarn included in the fabric of the present invention may range from about 70 denier to about 900 denier (about 78 dtex to about 1000 dtex).

It is preferred that the polyester bicomponent filament yarn is not a twisted or tangled combination with another, for example, one component or staple fiber. That is, it is preferred that the bicomponent filament yarn be woven separately from the other yarns in the fabric, in order to eliminate the cost of the additional step, obtain high stretchability and recoverability, and also provide high smoothness of the fabric surface.

It is further preferred that less than about 3% by weight of a resin or similar material is present in the fabric or attached to the fabric because this resin treatment can add cost and the benefits of the present invention are achieved without such costs . A further advantage of the present invention is that the polyester in the bicomponent filaments need not be partially removed from the fabric by chemical means, for example by the application of a chemical treatment such as a highly alkaline solution. While such resins and chemical treatments may be used with the present invention, we believe that the extensibility and recoverability of the fabric may be compromised and it is therefore desirable to eliminate this additional step.

The fabric of the present invention may have a plain, twill, or main structure. Examples of useful twill structures include, but are not limited to, regular twill (e.g., 2/1, 1/2, 1/3 and 2/2 twill), modified twill (here added additional lift to the weaving method) , Herringbone, and pointed twill. Examples of useful runner structures include 5-end (e.g., 1/5 and 2/5) and 8-end (e.g., 3/8) weaving.

Loom types that can be used to make the fabric of the present invention include air-jet looms, shuttle looms, water-jet looms, rapier looms, and gripper (projectile) looms.

Prior to testing, the fabrics and fibers were conditioned for 16 hours at 21 占 폚 +/- 1 占 폚 and 65% +/- 2% relative humidity.

The shrinkage values after thermal curing were measured as follows. Samples of the bicomponent polyester filaments used were formed with a scale of about 5000 g / dt (5,050 dtex) using Schenin with a tension of about 0.1 gpd (0.09 dN / tex). The scine was conditioned for at least 16 hours at 70 +/- 2 DEG F (21 +/- 1 DEG C) and 65 +/- 2% relative humidity. The skins were suspended from the stand substantially vertically and suspended at the bottom of the scale with a weight of 1.5 mg / dL (1.35 mg / dtex) (e.g., 7.5 g for 5550 dtex skins) And the length of the skew was measured within 1 mm and recorded as "C b ". During the test period, a weight of 1.35 mg / dtex remained on the scale. Then, a weight of 500 g (100 mg / d; 90 mg / dtex) was suspended from the bottom of the scale and the length of the scale was measured within 1 mm and recorded as "L b ". Crimp shrinkage value (%) (before thermal curing, as described for this test) "CC b "

CC b = 100 X (L b - C b ) / L b

500 g weight was removed and then the scale was hanged on the shelf and heat cured in an oven at about 225 ((107 캜) for 5 minutes with the 1.35 mg / dtex weight still in place, Phosphorus was removed from the oven and conditioned for 2 hours as described above. This step is designed to simulate commercial dry heat curing, one method of forming the final crimp in bicomponent fibers. The length of the skew was measured as described above and its length was recorded as "C a & quot ;. The 500 g weight was suspended again from the scale and the scale length was measured as above and reported as "L a & quot ;. Crimp shrinkage value (%) after heat curing "CC a " was calculated according to the following formula.

CC a = 100 X (L a - C a) / L a

In the examples, plain weave having 55 picks per inch (22 picks / cm) and 62 picks per inch (500 picks per inch) were used in a loom condition using a Dornier rapier loom at 500 picks per minute 24 picks / cm &lt; 3 &gt;). The yarns of poly (ethylene terephthalate) and poly (trimethylene terephthalate) ("Binary Polyester Yarn") are available from the DuPont Textiles and Interiors Company at 150 denier (167 dtex) T-400 Elasterelle; It consists of 40% by weight of poly (ethylene terephthalate) and 60% by weight of poly (trimethylene terephthalate) and has a crimp shrinkage value of 47% after thermal curing. Prior to beaming, the bicomponent fiber yarn used in the warp was weighed at 300 yards in poly (vinyl alcohol) size using a Suziki single-end sizing machine with a temperature in the sizing bath set at 107 ℉ (42 캜) / Min (274 m / min). The sized yarn was dried at 190 DEG F (88 DEG C) for about 5 minutes. The company was a ring-spun cotton yarn with 30 yarn counts. Poly (ethylene terephthalate) yarns ("monocomponent polyester yarns") in use were 50 filament yarns of 150 denier (167 dtex) woven and tangled made by Unifi, Inc.

Finishing each greige fabric by passing it under low tension through hot water three times at 160 DEG F, 180 DEG F and 202 DEG F (71 DEG C, 82 DEG C and 94 DEG C respectively); This was then mixed with 6 wt% Synthazyme TM (starch-hydrolytic enzyme from Dooley Chemicals LLC) at 160 ℉ (71 캜) for 30 min, 1 wt% Lubit TM 64 (a non-ionic lubricant from Sybron, Inc.) and 0.5 wt% Merpol LFH (surfactant, available from EI DuPont de Nemours & After a de-sizing / pre-scouring with a mixture of tribasic sodium phosphate (a registered trademark of EI du Pont de Nemours and Company), 0.5% by weight of trisodium phosphate was added. The fabric was then refined with 1 wt% of Rubit (R) 64 and 1 wt% of Merpol (R) LFH at 110 5 (43 캜) for 5 minutes, and the yellow disperse dye (Yellow reactive dye, if present) at pH 5.2 to 230 ((110 캜) for 30 minutes and then thermally cured on the tenter frame for 40 seconds at 340 ((171 캜) with downward feed in the oblique direction . (The weight percentage of the finishing component is based on the fabric weight.)

The possible elongation (%) of the fabric in the examples was determined as follows. Three 60 x 6.5 cm sample specimens were cut from each fabric. The long dimension corresponds to the oblique direction. Each specimen was unrolled equally on each side until it was 5 cm wide. One end of the fabric was folded to form a loop, and the seam was sutured across the width to secure the loop. The first line was drawn at 6.5 cm from the non-looped end of the fabric, and the second line was drawn 50 cm away from the first line ("GL"). Samples were conditioned at 20 +/- 2 DEG C and 65 +/- 2% relative humidity for at least 16 hours. The sample was then clamped in the first line and suspended vertically. 30 Newton weights were suspended from the loop, the samples were allowed to stretch by weight for 3 seconds, and then the weight was removed to remove the load from the fabric. The weight was again applied and the distance between the lines ("ML") was recorded in the nearest millimeter. The possible elongation (%) was calculated from the following equation (1) and the results from the three specimens were averaged.

&Quot; (1) &quot;

Possible elongation (%) = 100 x (ML-GL) / GL

The recovery rate (%) of the fabric in the examples was calculated as 100% minus fabric growth rate (%) (% fabric growth rate), which was measured as follows. Three new specimens were prepared as described for the possible elongation tests, extended to 80% of the previously measured elongation as previously measured, and held for 30 minutes under extended conditions. It was then relaxed without binding them for 60 minutes, followed by measuring the distance ( "L 2") between the lines again. The fabric growth rate (%) was calculated from the following equation (2), and the results from three specimens were averaged.

&Quot; (2) &quot;

Fabric growth rate (%) = 100 x (L 2 - GL) / GL

In describing an oblique repeating pattern in the fabric structure of an embodiment, " bi "means a bicomponent and" mono "means a component. The repeat pattern used was the most uniform for the weight percent of the bicomponent filament slopes present. For example, when the bicomponent filament yarn is present at a concentration of 50 wt%, the repeating pattern is "y / day / day / day" rather than "y / day / / Day / day / day / day "rather than " this / day / day / day / day / day" The most uniform repeating pattern is used to achieve high fabric uniformity in surface appearance, stretchability, and resilience, but this pattern is not required.

The possible elongation ("elongation") and "recovery rate" properties of the fabric produced in the examples are shown in Table 1 (plain weave) and Table 2 (twill weave). For clarity, the yarn used in the examples had the same linear density such that the sloped end percentage was equal to the slope weight percent. In the table, "Binary% by weight" is based on the total tilt weight. The "elongation per two percent by weight" and "percent recovery by two percent by weight" indicate the relative amounts of two-component polyester yarns in only the oblique direction.
