Description

Disperse Yellow 83 is a high-performance, synthetic organic dye belonging to the disperse dye class, identified by CAS NO 12270-47-2. It is valued for its excellent color fastness, thermal stability, and bright, consistent yellow hue, which is critical for achieving durable coloration in synthetic fibers. This product is essential for manufacturers in the textile industry who require reliable and vibrant dyes for polyester and its blends, as well as for specialty applications in plastics and inks where color integrity under processing conditions is paramount.

Application

• Textile Dyeing: Primary application for dyeing polyester (PET) fibers, yarns, and fabrics, including high-temperature exhaust and continuous thermosol processes.
• Synthetic Fiber Blends: Effective for coloring polyester/cotton and polyester/wool blends, providing good reserve on the cellulosic or wool components.
• Plastics Coloring: Used as a colorant for mass coloration of thermoplastic polymers like polystyrene, ABS, and polycarbonate where heat resistance is required.
• Ink Formulation: Suitable for specialty inks, including transfer printing inks for textiles and some solvent-based ink systems.
• Automotive Interiors: Employed in dyeing polyester fabrics used for automotive upholstery due to its good light and sublimation fastness.
• Sportswear and Outdoor Gear: Ideal for synthetic athletic apparel and outdoor fabrics demanding wash and perspiration fastness.
