What is "Reactive dyes" - Definition & Explanation

Dyes for cotton and other cellulosic fibres that actually react to form covalent bonds with cotton to produce a new chemical (e.g. Red cotton). They require large amounts of chemicals (salt and alkali) to fix the dyes and lots of water to wash off unfixed dye.
