Document Type and Number:
WIPO Patent Application WO/2022/194116
Kind Code:
A1
Abstract:
A composite fiber and a preparation method therefor. The composite fiber is formed by composite spinning of a polymer A and a polymer B; the composite fiber contains 5-50 wt% of a polyether structural unit; a crimp number A of the composite fiber after being treated in boiling water for 30 minutes and dried is 10-30 crimp/2.5 cm; and a crimp number B of the dried composite fiber after being immersed in softened water at 20°C for one minute and then wiping the surface moisture is 0-50% of the crimp number A. The composite fiber has good crimp performance and moisture absorption/desorption automatic stretching/shrinking characteristics, so that a fabric prepared from the fiber has good breathability.
