Abstract

PURPOSE: A drawn yarn having undrawn parts is heat treated and thinning treated to produce inexpensively the titled fiber suitably used for woven and knitted fabrics with cut-fluff touch because the ends of fibers are sharply pointed and deeply dyed by dyeing operation and the yarn has a touch close to natural animal hair.
CONSTITUTION: Polyester fibers such as polyethylene terephthalate fibers consisting of drawn parts 1 and undrawn parts 2 is heat treated at a temperature higher than 100°C, preferably higher 150°C and then treated with e.g., aqueous sodium hydroxide to reduce the weight so that the weight-loss degree becomes higher than 35wt% to form pointed parts 3 on the fiber ends.
