Description

C.I. Disperse Green 7 is a high-performance, synthetic organic dye belonging to the disperse dye class, widely recognized for its vibrant green hue. This product is essential for achieving durable and colorfast coloration on synthetic hydrophobic fibers, particularly polyester and its blends. It is a critical component for textile manufacturers, dye houses, and industrial colorant producers seeking reliable and consistent green shades for apparel, home furnishings, and technical textiles.

Application

• Polyester Fabric Dyeing: Primary application for dyeing 100% polyester textiles, including filament and spun yarns, in high-temperature (HT) or carrier dyeing processes.
• Polyester Blends: Effective for dyeing polyester/cotton and polyester/wool blends, where it selectively colors the polyester component.
• Automotive Textiles: Used for coloring polyester-based fabrics used in car interiors, requiring excellent light and sublimation fastness.
• Sportswear and Activewear: Ideal for synthetic athletic apparel due to its good wash and perspiration fastness properties.
• Home Furnishings: Applied in the dyeing of curtains, upholstery, and other decorative polyester fabrics.
• Transfer Printing: Suitable for use in the manufacture of dyes for sublimation transfer paper, used for printing on polyester substrates.
