Abstract: The invention relates to a process for after-treatment of anionically dyed natural and synthetic polyamide textile materials by means of polyurethanes containing quaternary ammonium groups.

Abstract: Condensation products of alkylenediamines of the formulaH.sub.2 N--C.sub.n H.sub.2n --NH.sub.2 I,in whichn represents 4-10,and an epihalogenohydrin or 1,3-dihalogeno-2-hydroxypropane are used for the after-treatment of natural and synthentic fibre materials which are dyed with anionic dyestuffs and contain polyamide groups.

Abstract: A polymeric compound obtainable by reactingA. a reaction product1. of a dihalogenohydrocarbon and/or dihalogenoalkyl ether and2. of a polyamine which contains primary and/or secondary amino groups and optionally tertiary amino groups, amide groups, urethane and/or urea groups and also ether groups in a molar ratio of 0.1 to 1.8:1 withB. an epihalogenohydrin or a 1,3-dihalogeno-2-hydroxypropanein a molar ratio of 0.2 mole to 5.0 moles of epihalogenohydrin per mole of base nitrogen or component A is used for treating fibre materials which contain hydroxyl or amide groups before or after dyeing or printing.

Abstract: 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 andR denotes a C.sub.1 -C.sub.18 -alkyl, cycloalkyl, aralkyl or aryl radical or one of the hydroxyalkyl groups ##STR2## with the proviso that the amount of N-2-hydroxyalkylamines in which R stands for a hydroxyalkyl group accounts for no more than 20 percent by weight of the hydroxyalkylamines used,if desired by co-condensation with polyols of the formulaA(OH).sub.n IIin whichA denotes a 2-, 3- or 4-valent aliphatic, cycloaliphatic, araliphatic or aromatic radical andn is a number from 2 to 4,and subsequent quaternization.

Abstract: 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.
