Water Soluble Acid Dyes are anionic dyes that are applied to fibres from neutral to acid dye baths. The Acid Dyes are partly attached to the fibre to form salt between anionic groups and cationic groups in the fibre. Acid dyes are used both commercially and by the studio dyer to dye protein/animal fibres that requires the use of an acid such as vinegar, acetic or sulphuric acid to set the colour. Water Soluble Acid Dyes are not substantive to cellulosic fibres.
