Acid Dyes

Acid Dyes provides high wash fastness as well as color quality. As water-soluble anionic dyes, these can be used from neutral to acid dye baths on fibers like nylon, modified acrylic fibers, silk, wool. The attachment to fiber is because of salt formation between anionic groups in dyes and cationic groups in fiber and is not substantive to cellulosic fibers. These can be used commercially by studio dyers for dyeing of protein/animal fibers.

Features :

• Suitable against angora, wool, silk, some nylons and synthetics
• Requiring acid like vinegar, acetic/sulphuric acid for of color
• Exists as anion in solution
• Very large class of these acid dyes comprises sodium salts of sulfonic acids/phenolic groups
• More soluble and having less tinctorial values with greater light fastness

Applications :

Acid dyes are used in dyeing:

• Leather
• Paper
• Nylon
• Modified acrylic fibers
• Silk
• Wool
