Description

Disperse Red 1 is a synthetic anthraquinone derivative belonging to the class of disperse dyes. This compound is valued for its ability to impart a bright red color to hydrophobic synthetic fibers with excellent fastness properties. It is primarily utilized by manufacturers in the textile industry for dyeing polyester, acetate, and nylon fabrics. The product is supplied as a high-purity powder, ensuring consistent color strength and batch-to-batch reliability for industrial applications.

Application

• Primary dyeing of polyester fibers and fabrics.
• Coloration of secondary acetate and triacetate textiles.
• Dyeing of nylon and polyamide-based materials.
• Mass coloration of synthetic polymers during fiber production.
• Used in the formulation of specialty inks for synthetic substrates.
• Employed in research and development for new dye formulations and color matching.
