Description

Disperse Red 274 is a high-performance synthetic dye belonging to the disperse dye class, widely recognized for its vibrant red color and excellent fastness properties. Its primary value lies in its exceptional affinity for synthetic hydrophobic fibers, providing deep, uniform, and durable coloration. This product is essential for manufacturers in the textile industry, particularly for dyeing and printing polyester and its blends, as well as for specialized applications in plastics and inks where color stability is critical.

Application

• Primary dyeing of polyester fibers and fabrics.
• Printing applications on polyester textiles.
• Coloration of polyester-cotton and other synthetic fiber blends.
• Mass coloration (spin dyeing) of synthetic polymers.
• Specialized applications in non-textile areas such as plastics and inks.
• Used in the production of colored films and sheets.
