Abstract

PURPOSE: To produce a sharpened fiber with a small difference in shape in good processing yield by carrying out a sharpening treatment of a synthetic fiber bundlelike aggregate in a treating liquid comprising a solvent or a hydrolyzing agent for the fibers and a thickener. CONSTITUTION: Bundles of synthetic fibers are wound in a paper to form fibrous bundles, which are then transversely arranged in a cage made of stainless steel. The resultant cage is subsequently dipped in a treating liquid comprising a solvent or a hydrolytic agent for the synthetic fibers and a thickener to carry out the tip sharpening treatment. Thereby, sharpened fibers having a small difference in sharpened shape at both ends of the fibrous bundles are produced in high processing yield.
