Description

C.I. Reactive Violet 13 is a high-purity, water-soluble reactive dye belonging to the vinyl sulfone class, designed for covalent bonding with cellulosic fibers. Its primary value lies in delivering excellent wash and light fastness properties, ensuring vibrant and durable violet to blue-violet shades on textiles. This product is essential for industrial dyers and textile manufacturers seeking reliable, consistent coloration for cotton, viscose, and other natural fibers.

Application

• Exhaust dyeing and continuous dyeing of cotton fabrics and yarns.
• Pad-batch and pad-steam dyeing processes for cellulosic textiles.
• Printing applications on cellulose-based materials to achieve violet hues.
• Dyeing of viscose rayon and other regenerated cellulose fibers.
• Used in combination with other reactive dyes to produce a wide range of compound shades.
• Application in the coloration of hemp and linen fabrics.
