Cotton fibres were treated with polyepichlorohydrin—dimethylamine and dyed with a selection of direct dyes. The pretreatment was found to reduce the amount of sodium chloride needed, and to increase exhaustion efficiency and perspiration fastness. The preparation and chemical characteristics of polyepichlorohydrin‐dimetnylamine, the dyeing of the modified cotton and the quality of the direct dyeings are also discussed.
