Organic Colourful Reactive Dyes attach themselves to their substrates by a chemical reaction that forms a covalent bond between the molecule of dye and that of the fibre. The Reactive Dyes becomes a part of the fibre and is much less likely to be removed by washing than are dyestuffs that adhere by adsorption. The Reactive Dyes are of different groups which are available for dyeing/printing purposes with varying dyeing parameters and fastness properties. Organic Colourful Reactive Dyes finds a large scale application in the tinting textiles.
