Description

Disperse Orange 118 is a high-performance synthetic dye belonging to the disperse dye class, widely recognized for its vibrant and durable orange coloration. Its primary value lies in its excellent sublimation fastness, wash fastness, and compatibility with hydrophobic synthetic fibers, ensuring long-lasting color integrity in demanding applications. This product is essential for manufacturers in the textile industry, particularly for dyeing and printing polyester, acetate, and nylon fabrics, as well as for specialized applications in plastics coloration.

Application

• Polyester Fabric Dyeing: Primary application for achieving bright, fast orange shades on polyester textiles via high-temperature dyeing methods.
• Textile Printing: Used in printing inks for synthetic fabrics to create sharp, durable patterns and designs.
• Nylon and Acetate Coloration: Effective for dyeing other synthetic fibers like nylon and acetate, offering good color yield and fastness properties.
• Plastics and Polymers: Employed as a colorant for mass-coloration of hydrophobic plastics such as polystyrene, polycarbonate, and certain engineering plastics.
• Transfer Printing: Suitable for use in the manufacture of transfer papers for the sublimation printing process on synthetic garments and promotional items.
