Links the chromophore to the reactive system. ⚗️ The Reaction Mechanism
Generally requires salt to drive the dye into the fibre and alkali to fix it. 🌍 Environmental Impact The Chemistry of Synthetic Dyes. Reactive Dyes
The part that provides color (usually azo, anthraquinone, or phthalocyanine groups). Solubilising Group: Often sulfonic acid salts ( SO3Nacap S cap O sub 3 cap N a ) that make the dye water-soluble. Links the chromophore to the reactive system
