REQUALIFING METHOD OF SYNTHETIC FIBER

摘要

A method of modification for man-made fibers such as viscose rayon and acryl, fiber is described. The fiber is spun in the presence of surfactant(polyvinylalcohol, polyvinylacetate, Na-CMC) has less than 30% amount against weight of the coagulation bath to give the hydrophilic property before passing into the expulsion bath of the surfactants. The fiber is proved hydroscopic.
