ABSTRACT:
Color yield of the coloration processes for textile and like materials, more especially of sublimable dyes applied by transfer printing, is enhanced by pretreatment of the material by deposition of 1 to 10% surfactant or other amphipathic substance. Preferred substances are cationic, anionic or non-ionic surfactants, which may be applied from aqueous solution at levels of 1 to 10% on the weight of the material. The material is dried before printing. The surfactants can be accompanied by swelling agents, catalysts or cross-linking agents. Preferred dyes for the printing stage are sublimable dyes containing chelatable groups, fibre-reactive groups or cross-linkable groups.
