Abstract: Stable and homogeneous aqueous formulations of surfactants with an HLB of less than or equal to 13, which additionally contain a compound of the formula I in which R is C1-C8-alkyl, C1-C8-alkenyl, phenyl, alkylphenyl or phenalkyl with, in each case, 1 to 4 C atoms in the alkyl chain or cyclohexyl, R is hydrogen, or one of the radicals mentioned for R or R and R together with the N atom denote a heterocyclic radical, M is an alkali metal or ammonium cation or an equivalent of an alkaline earth or aluminium cation, and m and n are each, independently of one another, numbers from 6 to 8. The presence of the compounds of the formula I makes it possible to prepare stable and homogeneous aqueous formulations even of those surfactants which are otherwise only sparingly soluble or even insoluble in water.

Abstract: Cellulosic fibrous materials are treated with N-containing, basic monomers at temperatures of up to 160 DEG C in preferably aqueous medium, polymerisation of the monomer taking place with grafting of the resulting polymer onto the cellulosic fibrous material. The fibrous material modified in this way is suitable for dyeing with anionic dyestuffs, in particular those which contain a fibre-reactive group, using solely low-electrolyte and alkali-free dyeing liquors.

Abstract: Process for dyeing textile material with pigment dyes, which comprises 1. pretreating the textile material with a polymer which consists wholly or partly of monomeric units of the formula I (I) where R1 and R2 are each hydrogen, (C1-C22)alkyl which may be interrupted by -CO-NH- or -NH-CO-, or C1-C4-hydroxyalkyl, R3 and R4 are each hydrogen or methyl, and Y-is a monovalent anion or one equivalent of a polyvalent anion, 2. then dyeing with a pigment dye in the presence of a leveling or dispersing agent by the exhaust method and if necessary 3. treating the dyeing in a liquor with a pigment binder and subsequently fixing it. This process makes it possible to dye textile material, in particular ready-made jeans garments, with pigment dyes by an exhaust method.
