Document Type and Number:
WIPO Patent Application WO/2019/142718
Kind Code:
A1
Abstract:
A dyeable polyolefin fiber which is a polymer alloy fiber having a sea-island structure in which the sea ingredient comprises a polyolefin (A) and the island ingredient comprises a polyester (B), the fiber having a degree of elongation of 10-80%. The polyester (B) in the dyeable polyolefin fiber has an orientation parameter, as determined by Raman spectroscopy, of 1.1-10.0. The dyeable polyolefin fiber is a highly lightweight polyolefin fiber capable of being brightly and deeply colored, is excellent in terms of color fastness and evenness in dyeing, and is suitable for use as a fibrous structure.
