Excellent, because the dye is chemically locked to the fibre.
Known for incredibly vivid and brilliant shades. The Chemistry of Synthetic Dyes. Reactive Dyes
While reactive dyes are safer than many older synthetics (like those using heavy metals), they require large amounts of salt and water for the fixation and rinsing processes. Modern research focuses on "low-salt" dyes and increasing the to reduce chemical waste. Excellent, because the dye is chemically locked to the fibre
The "business end" that reacts with the fibre (e.g., vinyl sulfone or cyanuric chloride). Modern research focuses on "low-salt" dyes and increasing
Generally requires salt to drive the dye into the fibre and alkali to fix it. 🌍 Environmental Impact
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
