Document Type and Number:
WIPO Patent Application WO/2017/098861
Kind Code:
A1
Abstract:
A moisture-absorbing core-sheath composite yarn is provided in which the sheath polymer is a polyamide, the core polymer is a polyetheresteramide copolymer, and the strength retention after a 150°C 1-hour dry heat treatment is 50% or higher. The core-sheath composite yarn has high moisture-absorbing performance, is more comfortable than natural fibers, and can retain the soft texture, durability, and moisture-absorbing/releasing performance even when laundered and dried repeatedly.
