Description

C.I. Reactive Blue 116 is a high-performance, vinyl sulfone-based reactive dye used for coloring cellulosic fibers. Its primary value lies in its excellent wash and light fastness properties, providing durable and vibrant blue shades on textiles. This product is essential for manufacturers in the textile dyeing and printing industries, particularly for cotton, viscose, and other natural fiber applications where a strong covalent bond with the fiber is required for long-lasting color.

Application

• Exhaust dyeing of cotton yarn and knitted fabrics.
• Continuous pad-steam and pad-batch dyeing of woven cotton fabrics.
• Printing applications on cellulosic textiles.
• Dyeing of viscose rayon and other regenerated cellulose fibers.
• Used in combination with other reactive dyes to achieve a wide range of blue and compound shades.
• Suitable for industrial dyeing processes requiring high fixation and reproducibility.
