Acid dyes are anionic, soluble in water and are essentially applied from acidic bath. These dyes possess acidic groups, such as SO3H and COOH and are applied on wool, silk and nylon when ionic bond is established between protonated –NH2 group of fibre and acid group of dye. Overall wash fastness is poor although light fastness is quite good. As dye and fibre contain opposite electrical nature, strike rate and uptake of acid dye on these fibres is faster; electrolyte at higher concentration is added to retard dye uptake and to form levelled shades. Acid generates cation on fibre and temperature helps to substitute negative part of acid with anionic dye molecules.
An acid dye is a dye that is typically applied to a textile at low pH. They are mainly used to dye wool, not cotton fabrics. Some acid dyes are used as food colorants, and some can also be used to stain organelles in the medical field.
Acid Dye for Wool, Silk , Feathers, Nylon, and Other Protein Fibers Acid Dyes are bright, light fast and color fast. These are the dyes we use on our Hand Dyed, Silk Caps, and Sheep Tails. These dyes can be used on any protein based fiber or textile ( produced by animals) and nylon. The directions for dyeing in the washing machine (not recommended for wool because of felting) or on the stove top are on each bottle. Colors may appear different on other monitors or computers. We also stock other colors for Acid Dyes, please check other listings in our store for those colors that are available.
