Abstract

The present invention provides a conjugate fiber containing a polyolefin and a polyamide selected from polycaprolactam, copolymers of caprolactam and hexamethylene adipamide, hydrophilic copolymers of caprolactam and ethylene oxide diamine, and blends thereof, wherein the polyamide has a number average molecular weight up to about 16,500. Further provided are a nonwoven fabric produced from the conjugate fiber and the process of producing the nonwoven fabric.
