Acid dyes are anionic water-soluble dyes that are used to alter the colour of fibres like silk, wool, nylon, and modified acrylic fibres from neutral to acid. The salt formation between anionic groups in the dyes and cationic groups in the fibre is credited with at least part of the attachment of the dye to the fibre. Water-soluble acid dyes do not affect cellulose fibres. Acid dyes are used to dye protein/animal fibres such as wool, silk, mohair, angora, alpaca, and some nylons and synthetics.
