SAPONIFICATION AGENT FOR ACETATE-BASED FIBER MATERIAL, METHOD FOR SAPONIFYING ACETATE-BASED FIBER MATERIAL, AND SAPONIFIED ACETATE-BASED FIBER MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a saponification agent for an acetate-based fiber material, wherewith the acetate-based fiber material can safely and well repeatably be saponified without such a dangerous compound as a strong alkali compound such as sodium hydroxide or potassium hydroxide, to provide a method for saponifying the acetate-based fiber material with the saponification agent, and to provide a saponified acetate-based fiber material.;SOLUTION: This saponification agent uses guanidine hydrochloride and a weak acid alkali metal salt or a guanidine weak acid salt as active ingredients.;COPYRIGHT: (C)2009,JPO&INPIT
