Monofluorotriazine/sulphatoelrylsulphone dyes:
With the combination of monofluorotriazine and vinylsulphone systems, e.g. Cibacron C dyes, both groups contribute to effective fixation under virtually the same conditions. The reactivity of the fluorotriazine group matches more closely that of the vinylsulphone group and makes a larger contribution to fixation than the less reactive chloro analogues . The fluorotriazine-fiber bonds are stable to an alkaline medium while the vinylsulphone-fiber bonds qare stable to an acidic medium. These dyes also provide an environmental advantage since they give very high fixation, minimizing effluent color. They are generally designed for pad application. Their excellent bath statility, high fixation and easy wash off properties make them especially suitable for pad-batch dyeing
