Description

C.I. Reactive Orange 62 is a high-performance, water-soluble reactive dye belonging to the azo chemical class. It is engineered to provide excellent color yield and wash-fastness on cellulosic fibers like cotton and viscose, forming a covalent bond with the fabric for superior durability. This dye is essential for textile manufacturers and dye houses seeking vibrant, long-lasting orange hues in applications ranging from apparel to home textiles. Its consistent quality ensures reliable batch-to-batch reproducibility for industrial-scale production.

Application

• Exhaust dyeing of cotton yarns and fabrics.
• Continuous pad-batch and pad-steam dyeing processes for cellulosic materials.
• Printing of textiles, including cotton and viscose, to create sharp, vivid patterns.
• Dyeing of blended fabrics where the cellulosic component requires coloration.
• Used in the production of dyed garments and home textiles like towels and bed linens.
• Suitable for applications requiring high wet-fastness and light-fastness properties.
