Classification: Milling Acid, Fast Acid, Equalising, Super-Milling Acid
Packaging type: Bag
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.
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
Pigments are the solid colored powder available in both organic as well as inorganic form and mainly find usage in changing of color. As these are unaffected physically/chemically by substrate in which these are mixed, some industry sectors these find use in include chemical compounding industries, ink, plastics, textile, agriculture and other areas.
