DEEPLY DYEABLE ULTRA-FINE CELLULOSE ACETATE FIBER HAVING SOFT TOUCH

摘要

PURPOSE:To provide the fiber exhibiting soft touch and deep dyeability by eluting polyethylene glycol(PEG) from a dry-spun PEG-containing cellulose acetate fiber to form ultra-fine fibers. CONSTITUTION:PEG is eluted with a solvent from a dry-spun cellulose acetate fiber containing 5-50wt.% of the PEG to provide the objective fibers comprising ultra-fine fibers.
