Printing of cationised cotton with reactive dyes

Abstract

The printing properties of cationised cotton that had been pretreated with 2,3-epoxypropyltrimethyl-ammonium chloride were examined. Fixation (steaming) time, colour yields, colorimetric properties fastness properties, staining of the white grounds and penetration behaviour were evaluated for a number of reactive dyes with cationised cotton fabrics. The cationisation of cotton was found to be very effective in reducing steaming times and washing off processes, and in increasing colour yield Fastness and other properties of the printings are also discussed.
