    • Textile cellulose material is printed or dyed with reactive dyes with the aid of foam. The foam is applied by applying to the cellulose material a foamed, aqueous prepartion which contains in addition to dye and fixing alkalis(1) a foam-forming agent(2) a homopolymer or copolymer of acrylamide or methacrylamide or preferably a graft polymer which is obtained from an addition product of an alkylene oxide, preferably propylene oxide, on an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide, and(3) the acid ester of a homopolymer of an ethylenically unsaturated aliphatic monocarboxylic or dicarboxylic acid and a polyethylene glycol, a terminal hydroxyl group of the diol having been etherified with an aliphatic monoalcohol having at least 4 carbon atoms, preferably stearyl alcohol, and the homopolymer having a molecular weight of 300 to 3,500.The cellulose material thus treated is then subjected to a heat treatment, for example steaming, to fix the dye.This very stable preparation produces without the use of thickenings, in particular alginates, a strong, level and crisp print which at the same time has an excellent handle.
    • 纺织纤维素材料借助泡沫印刷或染色活性染料。 通过向纤维素材料施加发泡的水性预制物,其中除了染料和固定碱之外还包含发泡剂(2),丙烯酰胺或甲基丙烯酰胺或优选接枝聚合物的均聚物或共聚物, 由至少三元脂肪醇的环氧烷,优选环氧丙烷的加成产物获得,例如 甘油和丙烯酰胺或甲基丙烯酰胺,和(3)烯属不饱和脂族单羧酸或二羧酸的均聚物和聚乙二醇的酸酯,二醇的末端羟基与具有至少4个碳原子的脂族一元醇醚化 原子,优选硬脂醇,分子量为300〜3,500的均聚物。 然后将如此处理的纤维素材料进行热处理,例如蒸煮以固定染料。 这种非常稳定的制剂在不使用增稠剂的情况下产生,特别是藻酸盐,强力,水平和清爽的印刷品,同时具有优异的手感。
