Description

Disperse Red 302 is a high-performance, anthraquinone-based disperse dye renowned for its excellent color fastness and thermal stability. This product is critical for achieving vibrant and durable red shades on synthetic fibers, particularly in demanding high-temperature dyeing processes. It is an essential raw material for manufacturers in the textile and plastics industries seeking reliable coloration solutions.

Application

• Primary dye for polyester (PET) fibers and fabrics, offering excellent wash and light fastness.
• Dyeing of polyamide (nylon) fibers, providing bright red hues with good leveling properties.
• Coloration of acetate and triacetate fibers for apparel and home furnishings.
• Mass coloration of plastics, such as polystyrene and polycarbonate, for consistent batch-to-batch color.
• Used in the production of color filters and other optical components.
• Potential application in the dyeing of hydrophobic synthetic blends.
