METHOD FOR PROCESSING REGENERATED CELLULOSE FIBER

摘要

PROBLEM TO BE SOLVED: To provide a processing method, not impairing the appearance even when washing is repeated without impairing the strength and the touch feeling by controlling fibrillation which is a defect of a polynosic fiber or a regenerated cellulose fiber produced by a solvent-spinning method. SOLUTION: A regenerated cellulose fiber is treated with an aqueous solution containing three components composed of an acid, hydrogen peroxide and a metal compound having decomposition activity to hydrogen peroxide and then heat-treated to suppress fibrillation of the polynosic fiber or the regenerated cellulose fiber produced by the solvent-spinning method.
