Description

Disperse Red 135 is a high-performance, monoazo-based disperse dye renowned for its excellent color fastness and brilliant red hue. It is a critical component for achieving deep, vibrant shades with superior wash and light fastness on synthetic fibers. This product is essential for manufacturers in the textile and specialty plastics industries seeking reliable and consistent coloration. Its specific properties make it a preferred choice for demanding dyeing applications where color integrity is paramount.

Application

• Primary dye for polyester fibers and fabrics, including textured yarns and microfibers.
• Dyeing of polyamide (nylon) textiles for apparel and home furnishings.
• Coloration of acetate and triacetate fibers used in linings and specialty garments.
• Batch and continuous dyeing processes in high-temperature dyeing machines.
• Printing pastes for textile transfer printing applications.
• As a colorant for select engineering plastics, such as polystyrene and ABS, where thermal stability is required.
• Used in the manufacture of filter materials and non-woven synthetic products.
