one. Acid dyes with Superior leveling traits: Such a acid dye is accountable for their very good leveling properties. Since the dye molecules have fewer attraction for your fiber they may migrate only slowly to the polymer devices of wool or nylon fibers.
These dyes are also insoluble in h2o and so are identified as specialized common Sulphur dyes. Its software method is as underneath:-
The anionic dye element (R–SO₃⁻) is the sole coloured species; the sodium cation performs no part during the coloration procedure.
The sulfur dyeing procedure for cotton fabric is an economical process. It can help to provide deep, durable shades on cloth.
