Description

C.I. Reactive Red 48 is a reactive azo dye specifically engineered for covalent bonding with cellulosic fibers. This compound matters for its excellent color fastness, high fixation rate, and bright red hue, which are critical for producing durable and vibrant textiles. Industries such as textile manufacturing, yarn dyeing, and fabric printing rely on this dye for its reliable performance and compatibility with standard reactive dyeing processes.

Application

• Textile Dyeing: Primary application for dyeing cotton, viscose, and other cellulosic fibers in exhaust and continuous dyeing processes.
• Yarn Dyeing: Used for coloring cotton and blended yarns to achieve consistent and deep shades.
• Fabric Printing: Suitable for printing applications on cellulosic fabrics, offering sharp print definition.
• Garment Dyeing: Applied in batch dyeing of finished cotton garments for fashion and apparel.
• Industrial Textiles: Coloring of technical textiles, home textiles, and upholstery fabrics requiring wash and light fastness.
• Leather Auxiliary Dyeing: Can be used in combination with other auxiliaries for dyeing certain types of leather.
