A method for the effective bleaching of textile goods at temperatures in the range of 100°to 140°F. which consists essentially in exposing the same to an aqueous solution, at said temperatures, containing a mixture consisting essentially of 25 to 75 parts by weight of N,N-dichloro-5,5-dilower alkyl

A method for the effective bleaching of textile goods at temperatures in the range of 100°to 140°F. which consists essentially in exposing the same to an aqueous solution, at said temperatures, containing a mixture consisting essentially of 25 to 75 parts by weight of N,N-dichloro-5,5-dilower alkyl hydantoin and from 75 to 25 parts by weight of an alkali metal, alkaline earth metal or ammonium bromide salt, said dilower alkyl containing up to 8 carbons.
