Pretreatment of cotton with polyepichlorohydrin‐dimethylamine produces a modified cotton that can be dyed under neutral conditions with selected low‐reactivity dyes using a small amount of salt or with selected high‐reactivity dyes without salt. The dyeings of treated cotton exhibit improved colour yield and high wash fastness. The properties and the quality of the reactive dyeings are discussed.
