MULTICOLORED COMPOSITE TEXTURED YARN AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a multicolored grain-like composite false-twist textured yarn excellent in soft feeling and resilience.;SOLUTION: This composite false-twist textured yarn is obtained by applying false twisting to yarn having core-sheath conjugate filament yarn (A) consisting of a polymer (Aa), composed substantially of polyester, arranged in a sheath part and a polymer (Ab), whose temperature dependence of elongation viscosity is larger than that of the above polymer (Aa), arranged in a core part. The false-twist textured yarn is characterized by continuously possessing irregular thick part and thin part in both of the above filament yarns (A) and (B) in longitudinal direction of yarn length and partially possessing hollow parts in the polymer (Ab) arranged in the core part of the above core-sheath conjugate filament yarn (A).;COPYRIGHT: (C)2001,JPO
