reactive dyes

Dyes which are bonded to fibers by irreversible, covalent bonds, rather than by the usual hydrogen bonding, electrovalent bonding, or solvation effects, all of which are reversible. Most reactive dyes may be used to color fibers other than cellulose, the only criterion being the presence in the substrate of a reactive hydrogen atom, which is present in wool, nylon, and cellulose acetate.
