Document Type and Number:
WIPO Patent Application WO/2017/190647
Kind Code:
A1
Abstract:
Disclosed is a core-sheath complex fibre, wherein the sheath component is polyamide, and the core component is an easily dissolvable polyester, and the tensile viscosity M of the polyamide and the tensile viscosity N of the easily dissolvable polyester in the fibre meet the following conditions: M - N ≥ 0 Pa·s at the same temperature of 255ºC or greater. The fibre can have an excellent light weight after being subjected to a weight reduction post-treatment, and has an excellent washing fastness after being dyed.
