Abstract:
A process for printing hydrophobic fibre materials with disperse dyes, which comprises1) dyeing or printing the fibre materials overall with a disperse dye, and 2) printing the fibre materials in areas with a printing paste, which comprises as component (A), at least one cationic assistant selected from the group consisting of organic polymer compounds containing quaternized amines; salts of nitrogen-containing organic polymer compounds and amine oxides of formula â€ƒwherein R is an aliphatic radical containing 8 to 24 carbon atoms, and R1 and R2 are each independently of the other an aliphatic radical which is unsubstituted or substituted by hydroxy, C1-C4 alkoxy, halogen, sulfo or acyl containing 1 to 24 carbon atoms, or a radical â€”(CH2CH2O)kW, wherein k is a number from 2 to 80, and W is C1-C4 alkyl, acyl, phenyl, naphthyl, benzyl or hydrogen, as component (B), at least one polyethylene glycol, as component (C), at least one nonionogenic detergent selected from the group consisting of fatty acid polyglycol esters which are optionally end-capped, fatty acid esters of polyvalent alcohols, naturally occurring and optionally partially saponified neutral fats and those compounds which are obtained by adding 4 to 80 ethylene oxide units and/or propylene oxide units to fatty alcohols, fatty amines, fatty acids or alkylaryls, and as component (D) a polypropylene glycol having a molecular weight in the range from 100 to 2000 and, optionally, as component (E), at least one disperse dye, it being possible for steps 1) and 2) to be carried out in any sequence and for step 2) to be carried out repeatedly without using any dye, or using different dyes, and, if necessary, drying the fibre material thus treated and then fixing the dye on the fibre material by heat treatment.
