Description

Disperse Red 73 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 consistent performance in demanding dyeing processes. This product is essential for manufacturers in the textile and polymer industries who require reliable and vibrant red coloration for synthetic fibers.

Application

• Textile Dyeing: Primary application for dyeing hydrophobic fibers such as polyester, acetate, and nylon, offering excellent wash and light fastness.
• Plastics and Polymer Coloring: Used as a colorant for mass-coloration of plastics like polystyrene, polycarbonate, and acrylic resins.
• Ink Formulation: A key pigment for specialty inks, including those used in ink-jet printing and textile printing pastes.
• Automotive Interiors: Employed in dyeing synthetic fabrics and plastics used for car seats, carpets, and interior trim.
• Sportswear and Outdoor Gear: Ideal for synthetic fabrics requiring durable, fade-resistant colors under UV exposure and frequent washing.
• Transfer Printing: Used in the manufacture of dyes for heat-transfer paper to print designs onto polyester fabrics.
