Description

Disperse Blue 284 is a high-performance synthetic dye belonging to the disperse dye class, specifically engineered for hydrophobic fibers. This product is valued for its excellent color fastness, brilliant blue shade, and strong build-up properties, making it a critical component in demanding coloration processes. It is primarily used by manufacturers in the textile and polymer industries for dyeing polyester, acetate, and nylon fibers, as well as for mass coloration of plastics.

Application

• Primary dyeing of polyester fabrics and yarns for apparel and home textiles.
• Dyeing of cellulose acetate and triacetate fibers.
• Coloration of nylon and polyamide-based textiles.
• Mass coloration (spin dyeing) of polyester and other synthetic polymers.
• Printing applications on synthetic fiber fabrics.
• Used in combination with other disperse dyes to achieve a wide range of navy, black, and blue shades.
