Document Type and Number:
WIPO Patent Application WO/2022/078422
Kind Code:
A1
Abstract:
Disclosed is a polyester composite blended fiber yarn. The polyester composite blended fiber yarn is composed of polyester filaments A and B, wherein polyester filament B forms filament circles outside polyester filament A; the length difference between polyester filament A and polyester filament B is 2-30%, and the boiling water shrinkage rate of polyester filament A is greater than that of polyester filament B by 3% or more; and after the polyester composite blended fiber yarn is treated in boiling water at 98ºC for 30 min, the length difference between polyester filament A and polyester filament B is increased by 15-200% as compared with the length difference before treatment.
