Description

Disperse Red 278 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 strong build-up properties on synthetic fibers. This product is essential for manufacturers in the textile industry seeking vibrant and durable coloration for polyester and its blends. The compound is also identified by the CAS registry number 68248-10-2.

Application

• Textile Dyeing: Primary application for dyeing polyester (PET) fibers, yarns, and fabrics to achieve a bright red shade.
• Plastic Coloring: Used as a colorant for mass coloration of hydrophobic plastics, including polycarbonate (PC) and polystyrene (PS).
• Ink Formulation: A key pigment for specialty inks used in transfer printing and inkjet applications on synthetic materials.
• Automotive Interiors: Suitable for dyeing synthetic textiles used in vehicle upholstery and interior trim due to its light and wash fastness.
• Sportswear and Outdoor Gear: Ideal for high-performance athletic apparel and outdoor fabrics requiring color durability.
• Acetate and Nylon Dyeing: Can be applied for dyeing secondary synthetic fibers like acetate and nylon under specific conditions.
