摘要
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,PPR is alkyl having 1 to 5 carbon atoms, hydroxyalkyl having 1 to 5 carbon atoms,PPa group of the formula ##STR2## (n=0 to 5), a group of the formula ##STR3## (X=oxygen or sulfur) (n=0 to 5), or R and A together are ##STR4## subsequently dyeing them by conventional methods, but without alkali, by means of the dyes mentioned, and completing the dyeing by rinsing, soaping and drying.
