Abstract: PURPOSE:To stably produce high-quality crimped woven fabric having uniform properties and soft drape properties. CONSTITUTION:Polyester multifilament yarn having >=40 single yarns, 0.5-1.5d single yarn denier, 23-35% elongation, 6-9% boiling water shrinkage, 5-80 coefficient of interlacement and 0.32+5/d -30 +30 (yarns/inch) as weft of weaving. The woven fabric is immersed in hot water at 10 deg.C or more higher than twisting stop temperature, crimped and then processed in weight loss by 10-40%.

Abstract: PURPOSE:To enable stable and high-speed production of the subject yarn free from uneven drawing and sag and capable of giving a high-quality grain- patterned woven fabric having excellent feeling by successively preheating and heat-drawing an undrawn polyester yarn using a specific method and subjecting the product to entanglement treatment under specific condition. CONSTITUTION:An undrawn polyester yarn composed of >=40 filaments is preheated by winding on a roller heated at 85-95 deg.C. The preheated yarn is drawn at a speed of 800-1,500m/min at a draw ratio satisfying the formula I [V1 is spinning speed (m/min) of the undrawn yarn; R is draw ratio] and, at the same time, heated by transferring in contact with a heater heated at 140-180 deg.C under the condition satisfying the formulas II and III [V2 is drawing speed (m/min); T is heat-treatment period (sec); D is denier of drawn yarn; F is tension (g) in heat-treatment] to effect the heat-treatment of the yarn. Finally, the drawn yarn is subjected to entanglement with a fluid treating nozzle to an entanglement coefficient K of 5-100 to obtain the objective fiber having a single fiber fineness of

Abstract: PURPOSE:To obtain separated single filament yarns at a low cost with reduced separation breakage near a separating guide, by drawing partially drawn polyester multifilament yarns having a specific birefringence, and by separating and winding the drawn yarns continuously. CONSTITUTION:The multifilament yarn 3 taken out of the zero-twist partially drawn multifilament yarn 2', e.g. polyester or polyamide having a birefringence of 15X10 -45X10 placed on the rotating creel 1 is passed around the rolls 9 and the pin 10 via the tension compensating guide 4 with the brake 19, then brought into contact with the hot plate 11, and passed through the rolls 12, guide 5, and separating guide 6 to separate into monofilaments or two or more subdivided multifilament groups, which are wound onto the bobbins 7. The yarn 3 is drawn by the rolls 9 and 12 due to the peripheral speed difference, and will not easily cause entanglements between filaments up to the separating guide 6.
