Hygienically Processed Reactive Cold Dyes get attached themselves to their substrates by a chemical reaction that results in a covalent bond among the molecule of dye and the fibre. These Reactive Cold Dyes exhibit good reactivity and fastness in action. These Reactive Cold Dyes are hygienically processed that ensures safety of usage. Hygienically Processed Reactive Cold Dyes belong to a class of highly coloured organic substances and can function in milder alkaline conditions.
