Abstract:
1. An aqueous or aqueous-alcoholic crease-resistant formulation comprising at least one cationic surfactant (CSA), for the treatment after washing in aqueous or aqueous-alcoholic medium of articles made of textile fibers, at least one copolymer of controlled architecture (C) that is soluble or dispersible in aqueous or aqueous-alcoholic medium, compatible with the surfactant (CSA) at pH of said formulation and at pH of use of said formulation, and comprising: at least one hydrophobic organic polymer block B, which is essentially nonionic, and at least one ionic or ionizable organic polymer block A, wherein a weight ratio of blocks B/blocks A ranges from 0.01 to 1, said copolymer of controlled architecture (C) being present in the formulation in an amount that can give said articles properties of crease resistance and/or ease of ironing.
