Traditional anionic dyeing of cotton requires large amounts of salt to assist dye sorption. This paper reports a method of using trimethylolmelamine (TMM), a com mon durable press finish, to treat cotton for dyeing. TMM pretreated cotton has re markably improved affinity for anionic dyes and no longer needs the assistance of salt in the dyebath. Furthermore, effluents from such processes contain much less dye than effluents from ordinary salt-assisted dyeings. This technology not only increases the efficiency of dyeing without salt, it also considerably decreases the burden of effluent treatment. By this method, cotton can also be dyed with acid dyes.
