Description

Disperse Yellow 64 is a synthetic organic dye belonging to the disperse dye class, widely recognized for its bright yellow hue. It is valued for its excellent color fastness properties, particularly its lightfastness and sublimation resistance, which are critical for demanding textile applications. This dye is primarily used by manufacturers in the textile and plastics industries seeking a durable and vibrant yellow colorant for synthetic fibers.

Application

• Textile Dyeing and Printing: Primary application for dyeing hydrophobic synthetic fibers such as polyester, acetate, and nylon, especially in high-temperature dyeing processes.
• Plastics Coloring: Used as a colorant for thermoplastics, including polystyrene, polycarbonate, and certain acrylics, where good dispersion and heat stability are required.
• Ink Manufacturing: Suitable for specialty inks, including those for transfer printing and certain types of inkjet inks designed for synthetic substrates.
• Automotive Interiors: Employed in coloring synthetic fabrics and plastics used in vehicle upholstery and trim due to its durability.
• Sportswear and Outdoor Fabrics: Ideal for performance apparel made from polyester, where color vibrancy and resistance to fading from sunlight and washing are essential.
• Masterbatch Production: Supplied as a high-strength powder for incorporation into color concentrates (masterbatches) used in plastic molding and extrusion.
