    • 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 preparation which contains in addition to dyes 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) an anionic graft polymer which has as grafting base a copolymerization product from (A) an alkyl acrylate or methacrylate, the alkyl radical having at least 8 carbon atoms, with (B) a dicarboxylic acid diester of an ethylenically unsaturated aliphatic dicarboxylic acid and a polyethylene glycol, a terminal hydroxyl group of the diol having been etherified with a C.sub.1 -C.sub.4 -alkyl radical, and contains as graft constituent side chains which stem from grafted-on polymerizable monomers which contain hydrophilic groups.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 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含水制剂,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)具有作为接枝碱的阴离子接枝聚合物,其由(A)丙烯酸烷基酯或甲基丙烯酸烷基酯,具有至少8个碳原子的烷基与(B)二羧酸 烯键式不饱和脂族二羧酸和聚乙二醇的二酯,二醇的末端羟基与C1-C4-烷基醚化,并且含有作为接枝的侧链,其由含有亲水性的接枝聚合单体 团体 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强烈的水平和清晰的印刷品,同时具有优异的手感。

    • A process for dyeing or printing organic fibrous material made e.g. of polyamide, polyester or polyacrylonitrile, and also of cellulose, said process comprising the use of a dyeing or printing assistant which contains a quaternary ammonium salt. The salt is a reaction product of a copolymer of maleic anhydride and ethylene, propylene or styrene, with a N,N-disubstituted n-alkylenediamine, a homopolymer of a vinylpyridine, or a quaternized copolymer of a vinylpyridine and styrene. The reaction product, the homopolymer, and the copolymer are quaternized with e.g. benzyl chloride. The ammonium salt can also be a homopolymer of a vinylbenzyl chloride which is quaternized with a tertiary monoamine. The fibrous material dyed or printed with e.g. direct or disperse dyes or with cationic dyes has excellent levelness, good penetration of the dye, and good wetfastness properties. It is also possible to obtain multi-shade effects by printing the material patchwise with a reserve paste and then dyeing it.
    • 用于染色或印刷有机纤维材料的方法, 的聚酰胺,聚酯或聚丙烯腈,以及纤维素,所述方法包括使用含有季铵盐的染色或印刷助剂。 该盐是马来酸酐与乙烯,丙烯或苯乙烯的共聚物与N,N-二取代的正构烷基二胺,乙烯基吡啶的均聚物或乙烯基吡啶和苯乙烯的季铵化共聚物的反应产物。 反应产物,均聚物和共聚物用例如季铵化。 苄基氯。 铵盐也可以是乙烯基苄基氯的均聚物,其与叔单胺季铵化。 用例如染色或印刷的纤维材料。 直接或分散染料或阳离子染料具有优异的水平度,良好的染料渗透性和良好的耐湿性能。 也可以通过用保留的糊剂贴片印刷材料然后染色来获得多色效果。
