Description

C.I. Reactive Blue 22 is a high-purity, reactive anthraquinone dye widely used in industrial coloration processes. Its primary value lies in its ability to form covalent bonds with cellulosic fibers, resulting in exceptional wash and light fastness properties. This product is essential for manufacturers in the textile industry seeking vibrant and durable blue shades on cotton, viscose, and other natural fabrics.

Application

• Primary application in the exhaust dyeing of cellulosic textiles like cotton and viscose.
• Used in continuous dyeing and printing processes for fabrics and garments.
• Suitable for dyeing leather and paper where reactive dye chemistry is applicable.
• Employed in the coloration of wood pulp for specialty paper products.
• Can be used in research and development for creating new dye formulations and color blends.
• Potential use in the dyeing of nylon under specific pH and temperature conditions.
