What is "Fiber reactive dyes" - Definition & Explanation

Fiber reactive dyes are dyes used to color cellulosic and protein fibers such as cotton, rayon and soy. The dyestuff bonds to the fibers through a chemical reaction and does not require the use of mordants. Therefore, direct dyes require less salts and heavy metals to be used to achieve optimal coloration and fixation than other commodity dyestuffs. When used correctly, this can reduce not only the salt and metal content of the effluent, but also the quantity of water used to remove excess dye and the amount of dye run off.
