Process for treating fibre materials

The treatment of cellulosic fibre materials before or after dyeing or printing with direct or reactive dyestuffs is carried out with aqueous liquors which contain quaternized polyethers which are obtained by condensation of N-2-hydroxyalkylamines of the formula ##STR1## in which R.sub.1 and R.sub.2, independently of each other, denote hydrogen or a C.sub.1 -C.sub.4 -alkyl radical and

Process for treating cellulosic fibre material

Surface-active esters of aliphatic polyols containing at least 3 hydroxyl groups and aliphatic, cycloaliphatic or araliphatic acylaminocarboxylic acids, which contain a total of at least 8, preferably 12-60, carbon atoms and which are acylated by aliphatic carboxylic acids with 1-4 carbon atoms, aromatic or araliphatic carboxylic acids or aliphatic, aromatic or araliphatic sulphonic, carbonic or carbamic acids, are suitable as auxiliaries in the dyeing of textile materials.
