Acid Dyes

Acid Dyes

Acid dyes are water-soluble anionic dyes applied primarily to protein fibers such as wool, silk, and nylon, as well as certain modified acrylics. Their dyeing mechanism relies on ionic interactions between the fiber’s cationic sites and the dye’s sulfonate groups. Acid dyes offer bright colors, excellent leveling, and good light fastness. They are widely used in fashion textiles, carpets, upholstery, leather, and inkjet printing. Their shade range spans from soft pastels to deep, vibrant tones. Depending on their structure, acid dyes are categorized into leveling, milling, and super-milling types, each tailored for specific fastness and application requirements.
