Abstract (en)
[origin: US4613335A] Textile cellulose material is dyed or in particular printed with vat dyes by applying to the cellulose material in the absence of air a foamed aqueous preparation which, in addition to the dye, alkalis, reducing agent, foam-forming agent, preferably also contains a homopolymer or copolymer of acrylamide or methacrylamide or in particular a graft polymer which is obtained from an adduct of an alkylene oxide, preferably propylene oxide, on an at least trihydric aliphatic alcohol, for example glycerol, and acrylamide or methacrylamide. The dyed or printed cellulose material is if desired subjected to a heat treatment, for example steaming, and is then oxidized to develop the color. The use of the foamed preparations makes it possible to obtain deep level dyeings and crisp prints without the use of thickeners; at the same time the textile materials thus obtained have excellent handle.
