Document Type and Number:
WIPO Patent Application WO/2020/129629
Kind Code:
A1
Abstract:
The preset invention relates to a composite fiber for obtaining a fiber that has a strength at 100% elongation of 0.04 cN/dtex or less. This composite fiber is configured from a component X that contains a polyvinyl-based thermoplastic elastomer or a thermoplastic polyurethane elastomer having a glass transition temperature of 0°C or less and a component Y that is an easily soluble thermoplastic polymer; the complex ratio (mass ratio) of the component X to the component Y, namely X:Y is from 90:10 to 50:50; and a cross-section of the fiber has a sheath-core structure wherein the component X constitutes the core part and the component Y constitutes the sheath part.
