Method for after-cleaning dyed textiles, i.e. to remove unfixed dye, involves using copolymers of at least two mono-unsaturated monomers containing nitrogen heterocycles, e.g. N-vinylpyrrolidone and N-vinylimidazole

摘要

A method for after-cleaning dyed textiles involves using copolymer(s) (I) of at least two mono-unsaturated monomers (B1) and (B2), each containing at least one nitrogen-containing heterocycle. Independent claims are also included for (1) an after-soaping agent (II) containing (I) (2) aqueous formulations of (II)
