Description

Disperse Red 277 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its excellent color fastness and thermal stability. This product is essential for achieving vibrant, durable red shades on synthetic fibers, particularly polyester and its blends. It is a critical raw material for textile dyeing and printing operations, as well as for manufacturers of specialty colorants and masterbatches seeking reliable and consistent coloration.

Application

• Textile Dyeing: Primary application for dyeing polyester (PET) fibers, yarns, and fabrics to achieve a bright red hue with good wash and light fastness.
• Textile Printing: Used in the printing of polyester and acetate fabrics, offering sharp print definition and color yield.
• Plastics Coloring: Suitable for the mass coloration of engineering plastics and synthetic fibers during polymer manufacture, where high-temperature processing stability is required.
• Ink Formulation: A key component in the manufacture of specialty inks for non-paper substrates, including certain types of transfer inks.
• Automotive Interiors: Used in the coloration of polyester-based automotive textiles, such as seat covers and headliners, where color consistency and durability are paramount.
• Sportswear and Outdoor Fabrics: Ideal for high-performance apparel due to its ability to withstand repeated washing and exposure to environmental elements.
