Description

Disperse Blue 143 is a high-performance, anthraquinone-based disperse dye widely recognized for its excellent color fastness and thermal stability. It is a critical component for achieving deep, vibrant blue shades with superior wash and light resistance in synthetic textiles. This product is essential for manufacturers in the polyester and acetate fiber dyeing industries, as well as for the coloration of various plastic materials.

Application

• Primary dyeing of polyester fibers and fabrics for apparel and home textiles.
• Dyeing of cellulose acetate and triacetate fibers.
• Mass coloration of plastics, including polyesters and polyamides (nylon).
• Printing applications on synthetic fabrics.
• Used in the production of colored masterbatches for synthetic fibers and plastics.
• Potential applications in specialty inks and coatings for synthetic materials.
