Monochlorotriazine / sulphatoethylsulphone dyes :
The presence of monochlorotriazine and sulphatoethylsulphone groups within the same dye molecule leads to higher fixation values. At low dyeing temperatures, the reaction between the vinylsulphone group and fiber is preferred. Also fixation via chlorotriazine our preferred . Both reactive groups can contribute the fixation process but the relatively higher reactivity of the vinylsulphone group ensures that most of the fixation this functional group. Further benfits of this system are attributed to the triazine ring that is capable of linking with a wide range of chromophores. Although these dyes give a high degree of exhaustion, they also have good wash off properties. A typical example of these dyes is C.I. Reactive Red 194.
