Description

Reactive Red 80 is a high-performance, vinyl sulfone-based reactive dye designed for the coloration of cellulosic fibers. Its primary value lies in its excellent wash and light fastness properties, ensuring vibrant and durable shades in demanding applications. This product is essential for textile manufacturers, particularly those specializing in cotton, viscose, and other cellulose-based fabrics, seeking reliable and consistent dyeing results.

Application

Reactive Red 80 is engineered for a range of textile dyeing and printing processes. Its key applications include:

• Exhaust Dyeing of Cotton: For batch dyeing processes to achieve deep, uniform red shades.
• Continuous Dyeing (Pad-Batch, Pad-Steam): Ideal for high-volume, efficient coloration of woven and knitted fabrics.
• Textile Printing: Used in pigment printing formulations for cellulosic textiles.
• Dyeing of Viscose/Rayon: Provides bright and clear shades on regenerated cellulose fibers.
• Dyeing of Blends: Suitable for cotton/polyester blends when used in appropriate combination dyeing processes.
• Industrial Textiles: For coloring textiles where good fastness to washing and light is required.
