Description

Disperse Red 90 is a high-performance, synthetic organic dye belonging to the disperse dye class, widely recognized for its excellent color fastness and thermal stability. It is a critical component for imparting vibrant, durable red shades to hydrophobic synthetic fibers, ensuring color integrity through demanding textile processing and end-use conditions. This product is essential for manufacturers in the textile and polymer industries seeking reliable coloration for polyester, acetate, and nylon materials.

Application

• Primary dyeing and printing of polyester fibers and fabrics.
• Coloration of acetate and triacetate textiles.
• Dyeing of nylon and polyamide materials.
• Mass coloration (dope dyeing) of synthetic polymers during fiber production.
• Used in the production of transfer papers for sublimation printing.
• Potential applications in coloring plastics such as polystyrene and acrylics.
