METHOD OF MANUFACTURING POLYAMIDE FIBER BY HIGH-SPEED SPINNING

摘要

PURPOSE: Provided is a method of manufacturing a polyamide fiber which does not generate yarn cuttings and hairs, and involves reasonable spinning workability. CONSTITUTION: A polyamide microfiber with a fineness of 1.0 denier or less is manufactured through high-speed spinning by adding titanium oxide to polyamide during the step of polymerizing it. The bottom of the spinneret is kept to be in an atmosphere heated at 180-220 deg.C.
