The Chemistry Of Synthetic Dyes. Reactive Dyes →

Known for incredibly vivid and brilliant shades.

The chemistry of reactive dyes centers on their unique ability to form a permanent covalent bond with the substrate, typically cellulose (cotton) or protein fibres (wool/silk). Unlike other dyes that simply "sit" on or inside the fibre, reactive dyes become a chemical part of the fibre itself. 🧪 Chemical Structure Reactive dyes consist of four primary components: The Chemistry of Synthetic Dyes. Reactive Dyes

Excellent, because the dye is chemically locked to the fibre. Known for incredibly vivid and brilliant shades

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. 🧪 Chemical Structure Reactive dyes consist of four

Links the chromophore to the reactive system. ⚗️ The Reaction Mechanism

A major challenge where the dye reacts with water instead of the fibre, creating "spent" dye that must be washed away.
