Description

Disperse Blue 166 is a high-performance synthetic dye belonging to the anthraquinone chemical class, widely recognized for its excellent color fastness and dispersion properties. This product is essential for achieving deep, vibrant blue shades with superior wash and light resistance in synthetic textiles. It is primarily required by manufacturers in the textile and polymer industries for dyeing polyester, acetate, and nylon fibers. The compound is supplied as a fine powder, ensuring optimal solubility and dispersion in dye baths for consistent, high-quality coloration.

Application

• Primary dyeing of polyester fibers and fabrics.
• Dyeing of secondary acetate and triacetate textiles.
• Coloration of nylon and polyamide-based materials.
• Mass coloration (spin dyeing) of synthetic polymers and plastics.
• Printing inks for synthetic textiles.
• Specialized applications in non-woven fabrics and technical textiles.
