Acid dyes are generally aromatic sulfonic acid sodium salt, containing sulfonic acid group, hydroxyl group and other groups. A few of them are carboxylic acid sodium salt, which can ionize into pigment acid anion in water and combine with amino or amide group on fiber. Therefore, acid dyes can be used for dyeing and printing of wool, silk and other protein fibers and polyamide synthetic fibers. Acid dyes have bright color and good color fastness. Most of these dyes are dyed in acid solution, so they are called acid dye dyeing.
