TEMPERATURE ADJUSTMENT FIBER

摘要

PROBLEM TO BE SOLVED: To provide a temperature adjustment fiber for preventing sudden temperature change of fiber structure due to environment temperature change.SOLUTION: The composite fiber is characterized in that a core 2 component is formed of crystallineα-olefin having a melting point of 20-50°C and a thermoplastic copolymer, theα-olefin is contained by 1.0-30.0 wt.%, the thermoplastic copolymer is contained by 99.0-70.0 wt.%, and the composite fiber is a core-sheath composite fiber. In addition, projections are formed on an interface 4 of the core 2 component and a sheath 1 component, and the number of the projections is four or more.
