Pigmenting of cellulose textiles: treatment with cationic compound and immersion in aqueous pigment dispersion

Pigmenting method comprising the steps of:

• treating a cellulose fiber textile product with a nitrogenous cationic compound selected from the group consisting of quaternary ammonium salts, pyridinium salts, dicyandiamides, polyamines and poly-4-vinylpyridine hydrochloride, tertiary amine polymers, polymers of quaternary ammonium salts and copolymers of quaternary ammonium salts and vinyl monomers, in an aqueous treatment liquid for cationically treating the textile product, the cationic compound being capable of cationizing the cellulose fiber of the textile product and the treating being effected so that the cationic compound permeates the textile product and cationizes the cellulose fiber, and
• treating the thus-treated textile product by immersing it in an aqueous dispersion liquid containing fine particles of a pigment and an anionic compound selected from the group consisting of anionic surfactants and anionic polymer compounds, the anionic compound being capable of dispersing and anionizing the fine particles of the pigment so that the fine particles of the pigment are taken up essentially completely into the cationically treated textile product and bind thereto, thus pigmenting the textile product therewith, the textile product being cationically modified by the cationic compound to render the surface of the textile product receptive to adsorption and adherence of the fine particles of the pigment in the presence of the anionic compound.
