Structure of reactive dyes:
The four characteristics feature of a typical reactive dyes are:
- The chromophoric grouping, contributing the color and much of the substantivity for cellulose;
- The reactive system, enabling the dye to react with the hydroxy group with water and cellulose;
- A bridge group that links the reactive system to the chromophore;
- One or more solubilizing groups, usually sulphonic acid substituents attached to the chromophoric grouping.
