    Abstract: A composition suitable for use in the treatment of textiles comprises an aqueous dispersion containing (a) a polyamide which is a co-condensate of 25-40% by weight of one or more lactams having 6-12 carbon atoms in the lactam ring or of equivalent omega-aminocarboxylic acids, 25-40% by weight of one or more salts of hexamethylene diamine with linear dicarboxylic acids having 6-12 carbon atoms, 25-40% by weight of one or more salts of 4,41-diamino-dicyclohexylmethane with linear dicarboxylic acids having 6-12 carbon atoms and 0-10% by weight of one or more other polyamide-forming substances and (b) a protective colloid which is a water-soluble copolymer having a K value of at least 90 and derived from 10-35% by weight of acrylic and/or methacrylic acid, 57.5-90% by weight of a mixture consisting of acrylamide and 5-40% by weight (on the whole of the monomers) of methacrylamide and 0-7.5% by weight of one or more other monomers. Suitable other polyamide-forming substances are dicarboxylic acids, omega-aminocarboxylic acids or diamines which are branched or contain a hetero atom in the chain, and C-substituted lactams. The other monomers in the protective colloid may be a -chloro-acrylic, phenylacrylic, crotonic, maleic, fumaric, itaconic, citraconic, mesaconic or vinylsulphonic acid or an anhydride, salt or ester thereof, methyl or ethyl acrylate or methacrylate, vinyl acetamide, N-dimethylacrylamide, N-methylacrylamide, N-ethylacrylamide or a vinyl lactam.

The dispersion may contain 0.5-5% by weight of the protective colloid based on the weight of the polyamide.
