The Chemistry Of Synthetic Dyes. Reactive Dyes [RECOMMENDED]

Typical of dyes (like Remazol). In an alkaline bath, the dye undergoes an elimination reaction to form a vinyl sulfone group, which then adds across the fiber's functional groups. Result: A highly durable covalent linkage. ⚡ Key Properties

Known for incredibly vivid and brilliant shades. The Chemistry of Synthetic Dyes. Reactive Dyes

A major challenge where the dye reacts with water instead of the fibre, creating "spent" dye that must be washed away. Typical of dyes (like Remazol)

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. The Chemistry of Synthetic Dyes. Reactive Dyes
