Patent number: 6500215Abstract: A process is disclosed for treating textile materials with selected amine oxides in order to change the aesthetics and/or make the materials more receptive to dyes. In particular, the treatment causes cellulosic materials to become more cationic and thus more receptive to anionic dyes with or without stiffening.
