Abstract
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. In a preferred embodiment, the process of the present invention is directed to treating fabrics containing cotton fibers but will work to a useful extent on wool, nylon and polyester. The process is carried out by contacting said fibers or fabric with selected amine oxide compositions. The amine oxide compositions can be padded onto the fabric or printed onto the fabric. If printed onto the fabric according to a particular design, the design then becomes visible on the fabric once dyed.
