Abstract

PURPOSE: A thermoplastic polymer is melt-spun through a special spinneret so that a plurality of polymer phases form a plurality of irregular blocks, solidified by cooling and split to produce the titled fiber having irregularity similar to natural fiber and its bundles.
CONSTITUTION: The melt spinning is conducted by using a spinneret in which each of adjacent nozzles has intermittent cuts so that the melted polymer extruded from a nozzle comes into intermittent contact with the polymer extruded from the adjacent nozzles at positions where nozzles between cut parts or narrowed parts. Thus, the melted polymer forms a plurality of different polymer phases on the spinneret surface, which form a plurality of different blocks. After solidifie and split, the fiber includes the parts A, B consisting of one section and the other parts C, D consisting of a plurality of sections at irregular intervals. The total cross section variation coefficient[CV(F)]ranges from 0.05 to 1.0
