Behaviour of the cationic flocculant, polyquaternary ammonium salt, in textile dye solutions containing traditional ingredients and finishing chemicals was investigated. It was shown that polyquaternary salt was prone to form complexes with anionic detergent, dispersing agent, thickeners, and some inorganic colloidal compounds. The role of such complexes in ionic or disperse dye binding processes was evaluated. The mechanism of incorporation of dyes into triple complexes leading to their precipitation, and problems of stability and cationic functionality of nonstoichiometric comlexes was discussed. New materials based on polyelectrolyte complexes were introduced.
