Description

C.I. Reactive Orange 39 is a high-performance, water-soluble reactive dye belonging to the azo chemical class. It is engineered to form a covalent bond with cellulosic fibers, delivering excellent wash and light fastness properties for durable coloration. This product is essential for textile manufacturers and dye houses specializing in the dyeing and printing of cotton, viscose, and other natural fibers. Its consistent quality ensures reliable batch-to-batch reproducibility for industrial-scale applications.

Application

• Primary application in the exhaust dyeing of cotton and viscose yarns and fabrics.
• Used in continuous dyeing processes, such as pad-batch and pad-steam, for uniform coloration.
• Employed in the printing of textiles, particularly for creating vibrant orange shades.
• Suitable for dyeing cellulosic blends with synthetic fibers like polyester under specific conditions.
• Applied in the coloration of non-woven fabrics and other cellulosic substrates.
• Can be used in research and development for creating new dye formulations and color matching.
