Description

C.I. Disperse Red 103 is a high-performance, anthraquinone-based disperse dye widely used for its excellent color fastness and thermal stability. This product is essential for achieving vibrant and durable red shades on synthetic fibers, particularly in demanding high-temperature dyeing processes. It is a critical raw material for textile manufacturers, masterbatch producers, and industrial colorant formulators serving the polyester, acetate, and nylon markets globally.

Application

• Primary dyeing of polyester fibers and fabrics, including textured yarns (POY, DTY, FDY).
• Coloration of cellulose acetate and triacetate fibers.
• Dyeing of nylon and polyamide-based textiles.
• Manufacture of color concentrates and masterbatches for plastic resins.
• Transfer printing and sublimation printing applications.
• Industrial applications requiring a stable red colorant for specialty polymers.
