Abstract

PURPOSE: To obtain collagenic fibers of high purity easily at a low cost, by dipping a pretreated raw split in a deflocculating solution consisting of an alkali (earth) metallic salt, (hypo)chlorite, a polyhydric alcohol and an acid, and disaggregating or opening the resultant fibers.
CONSTITUTION: A raw split which is dipped in water, fleshed, unhaired and limed is dipped in a deflocculating solution consisting of (A) 0.01W1wt%, based on the dry weight of the raw split carbonate of an alkali (earth) metal, e.g. sodium carbonate, (B) 3W15wt% (hypo)chlorite of an alkali (earth) metal, e.g. calcium hypochlorite, (C) 10W30wt% polyhydric alcohol, e.g. polyethylene glycol, (D) 0.01W0.5wt% acid, e.g. hydrochloric acid, and (E) 15W30wt% water, at ordinary temperature for 20hr or longer, and then disaggregated by the wet method or opened by the dry method.
