ABSTRACT:
Textile cellulose material is printed with a reactive dye by applying to the cellulose material a foamed aqueous preparation which, in addition to the dye, contains foaming agent and a homopolymer or copolymer of acrylamide or methacrylamide or preferably a graft polymer 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 printed cellulose material is then subjected to a heat treatment, for example steaming, to fix the dye.
This foamed printing color produces without the use of thickenings a deep, level and crisp print which also has excellent handle.
