Dyeing of Cationised Cotton with Acid Dyes

The production of cationised cotton fabrics, via Sandene 8425, 1,1-dimethyl-3-hydroxyl azetidinium chloride and 1,1-diethyl-3-hydroxy azetidinium chloride, greatly enhances the exhaustion and fixation of acid dyes. This paper shows that these dyes can be used in the absence of salt in a neutral medium. Wash fastness, light fastness and other properties were studied
