Description

Disperse Violet 28 is a high-performance synthetic dye belonging to the anthraquinone chemical class, valued for its excellent color fastness and thermal stability. This compound is a critical component for achieving deep, vibrant violet and purple shades in synthetic textiles. It is primarily used by manufacturers in the textile and plastics industries seeking reliable and consistent coloration for polyester, nylon, and acetate fibers.

Application

• Polyester Fabric Dyeing: The primary application for high-temperature exhaust and continuous thermosol dyeing processes.
• Nylon and Acetate Coloration: Used for dyeing synthetic fibers where good wash and light fastness are required.
• Plastics and Resins: Imparts color to engineering plastics, acrylics, and other polymer matrices during mass coloration.
• Ink Formulation: Serves as a colorant for specialty inks used in various industrial printing applications.
• Automotive Interiors: Used for coloring synthetic fabrics and plastics within vehicle cabins.
• Sportswear and Outdoor Gear: Provides durable coloration for performance fabrics that require resistance to sweat and UV exposure.
