Description

C.I. Reactive Orange 86 is a high-performance, water-soluble reactive dye belonging to the azo chemical class, designed for covalent bonding with cellulosic fibers. This product matters for its excellent color fastness, brilliant orange hue, and high fixation rate, which are critical for achieving durable and vibrant coloration in demanding textile applications. It is primarily needed by textile manufacturers and dye houses specializing in the dyeing and printing of cotton, viscose, and other natural fibers, where wash and light fastness are paramount.

Application

• Exhaust dyeing of cotton and regenerated cellulosic fibers (e.g., viscose, lyocell).
• Continuous pad-batch and pad-steam dyeing processes for woven and knitted fabrics.
• Textile printing applications for creating sharp, defined orange patterns.
• Dyeing of cotton yarns and garments, including knitwear.
• Used in combination with other reactive dyes to produce a wide range of brown and black shades.
• Suitable for use in effluent-conscious processes due to its good solubility and fixation properties.
