Title:
PARALLEL COMPOSITE FIBRE
Document Type and Number:
WIPO Patent Application WO/2017/202262
Kind Code:
A1
Abstract:
Disclosed is a parallel composite fibre, prepared by parallel composite spinning and then false twisting processing of polybutylene terephthalate with an intrinsic viscosity of 1.00-2.00 dl/g and a polyester with an intrinsic viscosity of 0.45-0.65 dl/g in a weight ratio of 70:30 - 30:70, wherein the difference between the intrinsic viscosity of polybutylene terephthalate and the polyester is 0.35-1.55 dl/g, the elastic elongation of the fibre is 20%-129%, and the elastic recovery rate of the fibre is 65% or more.
