Application
Acid dyes are highly soluble in water and have good light fastness compared to simple basic dyes. The acid used in the dye bath is usually vinegar or citric acid. The dye absorption rate is controlled by using sodium chloride. In textiles dyeing, acid dyes are effective for dyeing protein fibers, for example, animal hair fibers such as wool, alpaca, and mohair. They are also effective for silk and nylon dyeing but have minimum interest in dyeing any other synthetic fibers.
 

• It is useful in textiles, fertilizers and leather.
• Acid dyes are also used in detergents and metal anodization.
• It acts like the coolants for engines.
• It is used in wool for resulting in the ionic or salt link between the dye molecule and fiber polymer.
• It is also useful in silk with various colors. Silk exerts affinity for acid dyes at low temperature and dyeing is commenced at 40 degree celsius.
