A method for the effective bleaching of textile goods at temperatures at or below about 140`F which consists essentially in exposing same to an aqueous solution, at said temperatures, containing an amount effective for bleaching of a material capable of generating positive bromine ions (Br<s+>s) during the bleaching of said textile goods. The material may be available from a wide variety of sources, including alkali metal hypobromites or alkali metal hypochlorites with a source of bromide ion or a material being selected from the group consisting of: a) an organo-N-bromo compound selected from the group consisting of N-brominated-hydantoins; N-brominated isocyanurates; N-brominated melamines and N-brominated glycolurils; b) an organo-N-chloro-N-bromo compound selected from the group consisting of N-chlorinated-N-brominated-5,5-dialkylhydantoins; N-chlorinated-N-brominated isocyanurates; N-chlorinated-N-brominated melamines and N-chlorinated-N-brominated glycolurils; and c) an organo-N-chloro compound selected from the group consisting of N-chlorinated-5,5-dialkylhydantoins; N-chlorinated isocyanurates, N-chlorinated melamines and N-chlorinated glycolurils, in combination with an alkali metal or alkaline earth metal bromide salt, said alkyl containing up to 8 carbons. |
