Dye - Wikipedia

Dyes are classified according to their solubility and ,chemical, properties. ,Acid, dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to ,acid dye, baths. Attachment to the ,fiber, is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the ,fiber,.
