POLYPHENYLENE SULFIDE COMPOSITE FIBER AND NON-WOVEN FABRIC

摘要

Provided are: a composite fiber which comprises a resin containing polyphenylene sulfide as the main component and has excellent thermal adhesion properties while keeping thermal dimensional stability thereof; and a non-woven fabric. A composite fiber mainly composed of a component (A) and a component (B), wherein the component (A) is a resin containing polyphenylene sulfide as the main component and the component (B) is a resin containing polyphenylene sulfide as the main component and having a higher melt flow rate than that of the component (A), and wherein at least a part of the surface of the fiber is formed from the component (B).
