POLYESTER GRANDRELLE YARN-LIKE BULKY PROCESSED YARN HAVING SOFT TOUCH

摘要

PROBLEM TO BE SOLVED: To provide a polyester grandrelle yarn-like bulky processed yarn which has a soft touch and gives a fabric having a soft touch and a natural clear grandrelle yarn appearance, when woven or knitted and then dyed. SOLUTION: This polyester grandrelle yarn-like bulky processed yarn having a soft touch is characterized by blending a false-twisted polyester multifilament yarn A having a single filament fineness of≤1 dtex and comprising≥70 filaments with a polyester multifilament yarn B having a larger single filament fineness than that of the above-mentioned false-twisted polyester multifilament yarn A and a birefringence of 10 to 60×10-3. The polyester multifilament yarn B is preferably a cation-dyeable polyester multifilament yarn. The birefringence of the polyester multifilament yarn B is varied in the longitudinal direction to form thick-thin unevenness. COPYRIGHT: (C)2005,JPO&NCIPI
