Abstract: A mixture of a textile auxiliary (T) obtained by reacting epichlorohydrin and ammonia in defined mole ratio, and a polymeric compound (P) which is a water-soluble homopolymer of a mono- or di-allylamine, or a water-soluble copolymer consisting of mono-, di- or tri-allylamine units may be used as an aftertreatment agent for fixation of anionic and sulphur dyeings on cellulosic fibres. The treated dyeings have better fastness properties than dyeings treated with either (T) or (P) alone.

Abstract: Cationic fixing agents based on the reaction products of(a) a monofunctional or polyfunctional amine having one or more primary and/or secondary and/or tertiary amino groups and(b) cyanamide, dicyandiamide, guanidine or bisguanidinegive improved results when the reaction takes place in the presence of a catalyst (K) selected from metals, metal salts and heterocyclic nitrogen-containing organic bases, particularly zinc chloride.

Abstract: Polymeric compounds (A) obtained by the reaction of epihalo-hydrin with a polyalkylene polyamine are useful as textile treatment agents. As pretreatment agents they improve the color yield of the subsequent dyeing, as aftertreatment agents they improve fastness properties. Certain of the products (A) are novel.

Abstract: Aftertreatment of textile fibres which have been optically brightened or dyed or printed with certain direct dyes, or with basic or sulphur dyes, increases wet-fastness properties. The aftertreatment agent is a polymeric, polybasic amino compound, which is applied under alkaline conditions.

Abstract: Dyeings on hydroxy group- or nitrogen-containing fibres are improved by aftertreatment, simultaneously or sequentially, with (A) a polymeric reaction product of an amine with cyanamide, dicyandiamide, quanidine or bisguanidine and (B) a quaternary polyalkylene polyamine. A synergistic effect between (A) and (B) is observed.

Abstract: Aftertreatment of dyeings on cotton or nylon with (A) a polybasic compound which is the product of reacting a primary or secondary amine with cyanamide, dicyandiamide, guanidine or biguanidine and, sequentially or simultaneously (B) a precondensate formed by reacting a compound of type (A) with an N-methylol derivative gives wet fastness properties superior to those given by either (A) or (B) used alone.

Abstract: The fastness of direct dyes on cellulose substrates is improved by after-treatment with the reaction product of a quaternary polyalkylene polyamine with an N-methylol resin precursor, and heat curing in the presence of a catalyst. The unfixed portion of reactive dyes substantive to cellulose may also be given improved wet and light fastness by this treatment.

Abstract: The wet fastness of direct dyes on cellulose substrates is improved by after-treatment with the reaction product of an amine with cyanamide, dicyanodiamide, guanidine or biguanidine which is further reacted with an N-methylol resin precursor, and heat curing in the presence of a catalyst. The unfixed portion of reactive dyes substantive to cellulose may also be given improved wet fastness by this treatment, so that washing to remove unfixed reactive dye may not be necessary.

Abstract: The present invention provides a textile finishing process comprising applying to a substrate containing cellulose fibres an aqueous medium comprisingA. a water-soluble, monomeric, resin-forming precondensate consisting of one or more N-methylol derivates of melamine, urea, substituted ureas, triazones, carbamates and urones, or mixtures thereof, said derivative containing at least 3 N-methylol groups or their lower alkyl ethers,B. one or more compounds having solvent properties for disperse dyes, which also increase their substantivity to cellulose, and at the same time have affinity for polyester fibres.C. One or more reactive softeners which are capable of chemical reaction with the --OH groups of cellulose, thereby reducing their hydrophilic properties, andD. a catalyst system for the simultaneous cross-linking of components A, B and C which causes neglible yellowing of cellulose fibres up to a temperature of 220.degree.
