Description

C.I. Reactive Orange 107 is a high-performance, water-soluble reactive dye belonging to the azo chemical class, designed for covalent bonding with cellulosic fibers. This compound matters for its excellent color fastness, brilliant orange hue, and efficient application in modern exhaust and continuous dyeing processes. It is primarily needed by textile manufacturers and dye houses specializing in cotton, viscose, and other natural fiber blends, where consistent shade and wash durability are critical.

Application

• Exhaust dyeing of cotton and regenerated cellulose fibers (e.g., viscose, lyocell).
• Continuous pad-dry and pad-batch dyeing processes for woven fabrics.
• Dyeing of cotton yarns and knitwear for apparel and home textiles.
• Printing applications on cellulosic substrates to achieve vibrant orange shades.
• Used in combination with other reactive dyes to produce a wide range of compound shades.
• Suitable for industrial dyeing where high fixation yield and reproducibility are required.
