Abstract

PURPOSE:To obtain the titled, yarn, capable of satisfying specific physical properties, having excellent dyeability, heat-setting property and pleat recoverability and providing woven and knitted fabrics with soft feeling, by spinning polyethylene terephthalate and heat-treating the resultant yarn at a specific temperature while applying a stretch ratio. CONSTITUTION:The aimed filament yarn, obtained by spinning a fiber-forming polyester containing ethylene terephthalate units as main recurring units at a high speed to provide a raw yarn having micoorientation of 0.025-0.06DELTAn birefringence rate, heat-treating the resultant raw yarn under heating condition of 140-220 deg.C in dry heat or 100-180 deg.C in wet heat while applying 1-12% stretch ratio and satisfying 25-60g/d initial tensile resistance, 45-140% elongation, 1.36-1.40g/cm<3> density, 0.07-0.12 birefringence rate (DELTAn), -2-+5% shrinkage in boiling water.
