Title:
METHOD FOR MANUFACTURING ESTER-BASED ELASTIC FIBERS HAVING EXCELLENT UNWINDING PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2022/102889
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing ester-based elastic fibers having excellent unwinding properties, with the objective to provide ester-based elastic fibers, having excellent unwinding properties, by melt-spinning a polyether-ester block copolymer, thereby manufacturing elastic fibers so as for the cross-section thereof to be a cross-shaped cross-section with four protrusions, and thus allowing good unwinding properties without degrading physical properties.
