Description

Reactive Orange 29 is a high-performance, water-soluble reactive dye designed for the covalent bonding of cellulose fibers. This compound matters for its excellent color fastness, brilliant hue, and reliable batch-to-batch consistency, which are critical for industrial dyeing operations. It is primarily needed by manufacturers in the textile industry for dyeing cotton, viscose, and other cellulosic materials, as well as for applications in leather and paper coloration.

Application

• Exhaust dyeing and continuous dyeing of cotton fabrics and yarns.
• Printing applications on cellulosic textiles to achieve vibrant orange shades.
• Dyeing of viscose rayon and other regenerated cellulose fibers.
• Coloration of leather products where reactive dyes are specified.
• Specialty paper dyeing for high-value applications.
• Used in research and development of new dye formulations and processes.
