Process for dyeing textile material with pigment dyes, which comprises

Dyeing textile material with pigment dyes: pre-treatment with quaternary

A process for the alkali-free dyeing and printing of cellulose fibers by means of reactive dyes, direct dyes, acid dyes, water-soluble sulfur dyes or sulfur vat dyes, which comprises pretreating the textile material to be dyed with a wetting agent and a reaction product of an epihalogenohydrin with ammonia or an amine of the formula ##STR1## in which A is hydrogen, alkyl having 1 to 5 carbon atoms, hydroxyalkyl having 1 to 5 carbon atoms,

Process for the dyeing and printing of cellulose fibers in the absence

The wet-fastness properties of cellulose materials dyed with sulfur dyestuffs is improved by treating the cellulose materials, before, during or after dyeing, with a polymer which is a copolymer or homopolymer of a monomer of the formula ##STR1## wherein R.sup.1 and R.sup.2 denote, for example, hydrogen or (C.sub.1 -C.sub.22)-alkyl; R.sup.3 and R.sup.4 denote hydrogen or methyl; and Y.sup..crclbar. denotes, for example, a monovalent anion.

Wet-fastness properties of sulphur dyestuffs dyeings on cellulose

Process for alkali-free dyeing and printing with reactive dyes. Beforehand, the textile material is treated with a wetting agent and a reaction product of polyethyleneimine and a bifunctional alkylating agent. This is followed by dyeing with reactive dyes in a conventional manner but without the addition of alkali to fix the dyes.

Process for alkali-free dyeing and printing with reactive dyes

A textile auxiliary for improving the fastness of materials dyed or printed with a dyestuff is a copolymer of a diallylammonium monomer, a vinyl amide monomer and a (meth)acrylic ester monomer.

Copolymer, process for its preparation, and its use

Improvements in the fastness properties of substrates dyed with reactive dyestuffs are achieved by a dyeing after-treatment with an agent which is the reaction product polyethyleneimine and a bifunctional alkylating agent.

Process for producing dyeings with reactive dyestuffs

A padding auxiliary is used in a dyeing process using a padding liquor wherein the padding auxiliary is an aqueous solution or dispersion containing
