FLAME-RESISTANT PROCESSING OF CELLULOSIC FIBER WEB

摘要

PURPOSE:To perform a flame-resistant processing having excellent washing resistance without lowering the strength of a cellulosic fiber web by treating the cellulosic fiber web with an amidophosphazene compound containing by- produced ammonium chloride capable of being not separated therefrom. CONSTITUTION:A cellulosic fiber web is treated with a solution containing an amidophosphazene compound of the formula (m is >=3), massively by- produced ammonium chloride capable of being economically not separated from the compound of formula, and sodium trichloroacetate as an alkaline substance to provide the flame-resistant cellulosic fiber web having good washing resistance and exhibiting good flame resistance at an extremely low cost.
