Abstract

Abstract Animal hair-like synthetic fiber which comprises thermoplastic synthetic fiber having one or more narrow parts in middle part thereof and one or both sharpened end parts, and satisfying the following relationship: L/D>30, L1/D>30, d<0.7D and d1<0.7D wherein D is a diameter of the biggest part of the fiber, d is an average relative diameter of the narrow part, d1 is an average relative diameter of the sharpened end part, L is a length of the narrow part and L1 is a length of the tapered part of the sharpened end part. The animal hair-like synthetic fiber is employed for producing a pile fabric which has the hand touchness and appearance closely similar to those of natural furs.
