Description

C.I. Disperse Blue 125 is a high-performance, anthraquinone-based disperse dye widely recognized for its excellent color fastness and thermal stability. This product is essential for achieving deep, vibrant blue shades with superior wash and sublimation fastness on synthetic fibers. It is primarily used by manufacturers in the textile and plastics industries for dyeing polyester, acetate, and nylon fibers, as well as for mass coloration of polymers.

Application

• Primary dyeing of polyester fibers and fabrics for apparel and home textiles.
• Dyeing of cellulose acetate and triacetate fibers.
• Coloration of nylon and other synthetic fibers.
• Mass coloration (spin dyeing) of polyester and polyamide plastics and resins.
• Printing applications on synthetic fabrics.
• Production of colored masterbatches for the plastics industry.
