Description

Disperse Black 1 is a synthetic anthraquinone-based dye belonging to the disperse dye class, widely recognized for its deep black shade and excellent colorfastness properties. This high-performance dye is engineered for the coloration of synthetic fibers, offering superior wash and light fastness, which is critical for durable textile applications. It is an essential component for manufacturers in the textile industry, particularly for dyeing polyester, acetate, and nylon fibers, as well as for specialized applications in plastics and inks.

Application

• Primary dyeing of polyester fabrics and yarns for apparel and home textiles.
• Coloration of acetate and triacetate fibers used in linings and specialty garments.
• Dyeing of nylon fibers for automotive textiles, sportswear, and carpets.
• Mass coloration of plastics and synthetic polymers during the manufacturing process.
• Production of inks for specialized printing applications.
• Used in laboratory research and development for dye chemistry studies and new application testing.
