Description

Reactive Red 226 is a high-performance, bifunctional reactive dye belonging to the azo chemical class, designed for exceptional color fastness and dye yield. Its primary value lies in forming strong covalent bonds with cellulosic fibers, resulting in brilliant, wash-fast red shades that are critical for textile quality and durability. This dye is essential for manufacturers in the textile industry requiring reliable and vibrant coloration for cotton, viscose, and other cellulose-based fabrics.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing yarns, knits, and woven fabrics in jet, overflow, and beam dyeing machines.
• Continuous Dyeing Processes: Used in pad-batch and pad-steam ranges for efficient, large-scale fabric coloration.
• Viscose and Rayon Dyeing: Provides excellent penetration and levelness on regenerated cellulose fibers.
• Blend Dyeing: Suitable for dyeing cotton-rich blends with polyester or other synthetic fibers.
• Garment Dyeing: Applied for achieving consistent and fashionable red shades in finished apparel.
