Description

Disperse Violet 77 is a synthetic anthraquinone-based dye belonging to the disperse dye class, known for its vibrant violet hue. Its primary value lies in its excellent sublimation fastness and wash fastness properties, making it a critical component for achieving durable coloration on synthetic fibers. This product is essential for manufacturers in the textile industry, particularly for dyeing and printing polyester and its blends, as well as for niche applications in plastics and specialty inks.

Application

• Primary dyeing of polyester fibers and yarns.
• Printing applications on polyester fabrics.
• Coloration of polyester-cotton and other synthetic fiber blends.
• Mass coloration (dope dyeing) of synthetic polymers.
• Specialized applications in the coloration of plastics (e.g., polycarbonate, polystyrene).
• Manufacture of color filters and inks for specialized printing.
