Abstract: The wet fastness properties of direct or reactive dyeings on cellulosic substrates are improved by aftertreatment with a precondensate of(A) the product of reacting a mono- or polyfunctional primary or secondary amine with cyanamide, dicyandiamide (DCDA), guanidine or biguanidine; or ammonia with cyanamide or DCDA; whereby up to 50 mole % of the cyanamide, DCDA, guanidine or biguanide may be replaced with a dicarboxylic acid or a mono- or di-ester thereof, said product (A) containing reactive hydrogen atoms bound to nitrogen, and either(B) an epihalohydrin or a precursor thereof, or(C) formaldehyde or a formaldehyde precursor, or(D) a dihydroxyalkyleneurea or a methyl ether thereof,followed by formaldehyde or a formaldehyde precursor optionally together with(E) an N-methylol derivative of a urea, melamine, guanamine, triazinone, urone, carbamate or acid amideand, if (A) is used with (C) or (D), or if (E) is present, together with(F) a catalyst for the cross-linking of N-methylol compounds of the type (E) abov

Abstract: The invention concerns polymeric basic amides produced by reacting a polymer containing carboxyl groups and a polyamine which contains an alkyl or alkenyl radical of 11 to 22 carbon atoms, at least one ethylene or propylene radical and at least two nitrogen atoms, of which at least one forms a primary or secondary amino group, at a temperature over 100.degree. C., which in the form of their acid salts are water-dispersible and useful textile softeners.
