Acid dyes are water-soluble dyes primarily used for protein fibers such as wool, silk, and nylon, offering bright and vibrant colors with excellent light and wash fastness. These dyes bond chemically with fibers, ensuring deep penetration and durable shades suitable for apparel, home textiles, and technical applications.
