Beschreibung
Zusammenfassung:	The present invention relates to a composite fiber for obtaining a fiber having a strength at 100% elongation of 0.04 cN/dtex or less,wherein the composite fiber is composed of component X comprising a polyvinyl-based thermoplastic elastomer, or a thermoplastic polyurethane elastomer having a glass transition temperature of 0° C. or lower, and component Y which is an easily soluble thermoplastic polymer,wherein the composite ratio (mass ratio) X:Y of the component X and the component Y is within the range of from 90:10 to 50:50, andwherein the composite fiber has a core-sheath structure in which the component X constitutes the core component, and the component Y constitutes the sheath component, in a cross section of the fiber.
