Abstract

PURPOSE: Polyester fiber in which the top end is sharpened and the surface has a large nujber of linear cracks, thus having appearance quite similar to annimal hair and good touch.
CONSTITUTION: Polyester fiber preferably containing 0.1W10wt% organic sulfonate salt is treated with an alkali solution at the fiber end to sharpen it and simultaneously form linear cracks along the fiber axis on the surface at the fiber end at least, thus producing the objective fiber. In the objective fiber, more than half of the linear cracks is more than 5 micron long and the ratio of length/maximum crack width is more than 5. Further, there are more than 0.05/micron of linear cracks in parallel at an arbitrary place on the end surface preferably.
