Description

C.I. Reactive Orange 12 is a high-purity, water-soluble reactive dye belonging to the azo dye class, specifically engineered for covalent bonding with cellulosic fibers. Its primary value lies in delivering brilliant, wash-fast orange shades with excellent reproducibility and good all-around fastness properties. This product is essential for textile manufacturers and dye houses specializing in the coloration of cotton, viscose, and other natural fibers via exhaust, pad-batch, or continuous dyeing processes.

Application

• Exhaust dyeing of cotton yarn and knitted fabrics.
• Pad-batch and continuous dyeing of woven cotton textiles.
• Coloration of viscose rayon and other regenerated cellulosic materials.
• Used in combination with other reactive dyes to produce a wide range of brown, gold, and deep orange hues.
• Suitable for garment dyeing applications.
• Applicable in the dyeing of cellulosic blends when using appropriate dyeing techniques.
