Description

Disperse Yellow 93 is a high-performance synthetic organic dye belonging to the disperse dye class, identified by CAS No. 56509-56-9. It is valued for its excellent color fastness, thermal stability, and bright, consistent yellow hue, making it a critical component for achieving vibrant and durable coloration. This dye is primarily needed by manufacturers in the textile and polymer industries seeking reliable and efficient coloring solutions for synthetic fibers.

Application

Disperse Yellow 93 is engineered for dyeing and printing synthetic fibers where high wash and light fastness are required. Its key applications include:

• Textile Dyeing: Primary application for coloring polyester (PET), acetate, and triacetate fibers.
• Textile Printing: Used in printing pastes for creating patterns on polyester fabrics.
• Plastics Coloring: Imparting a stable yellow color to engineering plastics like polystyrene, ABS, and polycarbonate.
• Ink Formulation: A pigment source for specialty inks where solvent resistance is needed.
• Automotive Interiors: Coloring synthetic fabrics and plastics used in vehicle upholstery and trim.
• Sportswear Fabric: Providing fade-resistant color for high-performance athletic apparel made from polyester.
