  Abstract

A new dye intermediate and novel reactive dyes containing both azo and benzsulfonamide auxochromic groups were synthesized. Their structures were characterized by 1H-NMR, 13C-NMR, MS, IR, and UV-Vis spectral analysis. The synthesized dyes were applied to dyeing of cotton fabrics and their dyeing parameters were assessed. The new dyes exhibited improved substantivity and fixation property on cotton fabrics compared with the dye C.I. Reactive Black 5 (RB5). The maximum exhaustion and total fixation values of the reactive dyes appeared when 2 % owf of the dye concentration was used. The wash fastness and rub fastness of the new dyes reached up to 4 grade and 4-5 grade, respectively. In addition, they showed excellent fastness to light. These new dyes seem to be promising candidates for application to dyeing of cotton fibers.
