Abstract: 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.

Abstract: Process for the alkali-free dyeing and printing of cellulose fibres with reactive dyes, direct dyes, acid dyes, water-soluble sulphur dyes or sulphur vat dyes, wherein the textile material to be dyed is pretreated with a wetting agent and a reaction product of an epihalogenohydrin and ammonia or an amine of the formula where A is hydrogen, alkyl having 1 to 5 carbon atoms or hydroxyalkyl having 1 to 5 carbon atoms, R is alkyl having 1 to 5 carbon atoms, hydroxyalkyl having 1 to 5 carbon atoms, a group of the formula (n = 0 to 5), a group of the formula (X = oxygen or sulphur) (n = 0 to 5), or R and A together are then dyed with the dyes mentioned in a conventional manner but without alkali, and the dyeing is finished by rinsing, soaping and drying.
