Acid Dyes are a group of water-soluble dyes that are widely used in the textile, leather, and paper industries. These dyes are typically anionic in nature, meaning they carry a negative charge, and they bond with positively charged sites in fibers, particularly protein-based fibers like silk, wool, and nylon. Acid dyes are known for their brilliant colors and good dyeing properties.
