Description

Reactive Red 222 is a high-performance, water-soluble azo dye belonging to the reactive dye class, widely recognized for its excellent color fastness and brilliant red hue. Its primary value lies in forming a strong covalent bond with cellulose fibers, ensuring exceptional wash and light fastness in the final textile product. This dye is essential for manufacturers in the textile industry, particularly for dyeing and printing cotton, viscose, and other cellulosic fabrics, where vibrant and durable coloration is a critical commercial requirement.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, linen, rayon, and other cellulosic fibers.
• Textile Printing: Used in printing pastes for creating sharp, vivid red patterns on cellulosic fabrics.
• Garment Dyeing: Suitable for dyeing finished cotton garments, offering uniform and deep shades.
• Yarn Dyeing: Employed for dyeing cotton and blended yarns intended for weaving or knitting.
• Industrial Applications: Potential use in coloring paper and leather where reactive properties are beneficial.
