Description

Acid Violet 109 is a synthetic anthraquinone-based acid dye known for its vibrant violet hue and excellent color fastness properties. This high-performance dye is engineered to deliver superior wash and light fastness, making it a critical component for achieving durable and consistent coloration. It is primarily utilized by manufacturers in the textile and leather industries for dyeing polyamide fibers, silk, and wool, where quality and color retention are paramount.

Application

• Dyeing of polyamide (nylon) fibers for apparel, sportswear, and automotive textiles.
• Coloration of wool and silk fabrics and yarns.
• Leather dyeing for footwear, upholstery, and fashion accessories.
• Used in the production of inks and pigments for specialized printing applications.
• Potential use in the coloration of paper and other specialty materials.
