Abstract

PURPOSE: To titled fibers, consisting of sheath and core type polyester composite fibers, having one tip thereof in the long direction in a specific shape, resembling the natural animal hair used for a high-class fur, etc., and having improved color appearance.
CONSTITUTION: Sheath and core type composite fibers having sheath and core components consisting of a polyester polymer, preferably a polyester copolymer having dyeable sites, and a polyester polymeric composition capable of exhibiting different coloring properties are formed into a bundle-like aggregate. One end of the aggregate is then dipped in a solution containing a hydrolyzing agent, e.g. an alkali, and the dipped parts are totally hydrolyzed and removed to give aimed fibers, in which at least one end thereof is tapered in the long direction gradually toward the tip, and the tip has a tapered shape forming an acute angle such as that made by intersecting two straight lines with the core component exposed to the tip part to form a sharp end only by the core component.
