Description

Disperse Red 118 is a high-performance synthetic dye belonging to the disperse dye class, widely recognized for its vibrant red hue and excellent fastness properties. This compound is essential for achieving durable and colorfast coloration on synthetic hydrophobic 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 quality for demanding applications.

Application

• Primary dyeing of polyester fibers and yarns for apparel and home textiles.
• Printing of polyester fabrics, offering sharp and brilliant print designs.
• Coloration of polyester-cotton and other synthetic fiber blends.
• Manufacturing of color concentrates and masterbatches for plastics.
• Industrial applications requiring a stable red colorant for specific polymers.
• Research and development of new dye formulations and color systems.
