The Chemistry Of Synthetic Dyes. Reactive Dyes • Deluxe
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
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. Typical of dyes (like Remazol)
Excellent, because the dye is chemically locked to the fibre. vinyl sulfone or cyanuric chloride).
Known for incredibly vivid and brilliant shades.
The "business end" that reacts with the fibre (e.g., vinyl sulfone or cyanuric chloride).
