Description

Disperse Red 137 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its excellent color fastness and thermal stability. This product is essential for achieving vibrant and durable red shades on synthetic fibers, particularly polyester and its blends. It is a critical raw material for textile manufacturers, dye producers, and industrial colorant formulators seeking reliable and consistent coloration for high-quality fabrics and specialty materials.

Application

• Primary dyeing and printing of polyester (PET) fibers and yarns.
• Coloration of polyester-cotton and other synthetic fiber blends.
• Manufacture of dye concentrates and masterbatches for mass coloration.
• Used in the high-temperature dyeing processes typical for synthetic textiles.
• Potential application in the coloration of acetate and nylon fibers.
• Supplied as an intermediate for specialty ink and pigment formulations.
• Suitable for automotive, upholstery, and other textiles requiring excellent wash and light fastness.
