Abstract

PURPOSE: To obtain acrylic fibers having scaly protrusions on the surfaces, with a size≤0.5 denier, by wet spinning an acrylonitrile solution in a specific aqueous nitric acid of specific concentration into an aqueous nitric acid coagulant of specified concentration under specific conditions of orifice diameter, draft ratio, etc., followed by drawing at a specific draw ratio.
