Description

Reactive Orange 122 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, ensuring brilliant and durable orange shades that resist washing and light exposure. This product is essential for textile manufacturers and dye houses specializing in the coloration of cotton, viscose, and other natural fibers, where consistent shade reproduction and process reliability are critical.

Application

• Exhaust dyeing of cotton and viscose yarns and fabrics.
• Continuous pad-batch and pad-steam dyeing processes for cellulosic textiles.
• Used in combination with other reactive dyes to achieve a wide spectrum of orange and red-brown shades.
• Ideal for applications requiring high wash fastness and light fastness.
• Suitable for dyeing in modern, low-salt or salt-free reactive dyeing systems (where applicable based on grade).
• Potential use in the coloration of leather and paper where reactive dyes are specified.
