Description

Disperse Yellow 232 is a high-performance synthetic organic dye belonging to the disperse dye class, specifically engineered for hydrophobic substrates. Its primary value lies in providing excellent color fastness, brilliant shade, and superior dispersion properties, which are critical for consistent dyeing results. This product is essential for manufacturers in the textile and polymer industries who require reliable and vibrant yellow coloration for synthetic fibers, particularly polyester and its blends.

Application

• Primary dyeing and printing of polyester fibers and filaments.
• Coloration of polyester-cotton and other synthetic fiber blends.
• Mass coloration (dope dyeing) of polyester resins and plastics.
• Industrial applications requiring a lightfast yellow pigment for specific polymers.
• Used in the production of colored masterbatches for synthetic fabrics.
• Potential use in specialty inks for transfer printing on synthetic textiles.
