Abstract
A series bifunctional azo reactive dyes containing two anionic sulphatoethylsulphone (SES) derived from 1,4’-benzenediamine as a tetrazotised solution were prepared by coupling to 4-nitroanilino cyanurated acids (H-acid, J-acid, Laurent acid, Tobias acid and Gamma acid).The synthesised dyes were applied on nylon 6 fabric under typical exhaustion process and their dyeing properties were evaluated. The structures of the synthesised dyes were characterised and confirmed by melting point, UV-visible spectroscopy, FT-IR spectroscopy, 1HNMR, and MS. The percentage exhaustion and percentage fixation of the synthesised dyes on nylon 6 fabric was very good. All the synthesised dyes gave well to excellent properties to washing, light and perspiration respectively
