Description

C.I. Disperse Yellow 122 is a high-performance, monoazo-based disperse dye essential for achieving vibrant and durable yellow shades on synthetic fibers. Its primary value lies in its excellent fastness properties, including lightfastness and sublimation fastness, which are critical for demanding textile applications. This dye is specifically engineered for the coloration of polyester and its blends, meeting the stringent quality and consistency requirements of the global textile manufacturing and dyeing industries.

Application

• Primary dyeing and printing of polyester (PET) fibers and filaments.
• Coloration of polyester-cotton and polyester-wool blended fabrics.
• Used in high-temperature dyeing processes, including carrier dyeing and high-temperature pressure dyeing.
• Application in transfer printing inks for synthetic textiles.
• Manufacture of masterbatches for mass coloration of plastics and synthetic fibers.
• Suitable for automotive textiles requiring high lightfastness and washfastness.
• Used in the production of colored polyester sewing threads.
