Description

Reactive Blue 160 is a high-performance, vinyl sulfone-based reactive dye designed for the coloration of cellulosic fibers. Its primary value lies in its excellent wash and light fastness properties, ensuring vibrant and durable color in demanding applications. This product is essential for textile manufacturers, particularly those specializing in cotton and viscose, who require reliable and consistent dyeing results for apparel, home textiles, and industrial fabrics. Reactive Blue 160 CAS NO 71872-76-9 is a key component for achieving a wide range of blue to turquoise shades in exhaust, pad-batch, and continuous dyeing processes.

Application

• Exhaust dyeing of cotton yarn and knitted fabrics.
• Pad-batch and continuous dyeing of woven cotton and viscose fabrics.
• Coloration of cellulosic fibers for apparel such as denim, t-shirts, and shirts.
• Dyeing of home textiles including towels, bed linens, and curtains.
• Used in the production of industrial textiles requiring color fastness.
• Can be applied in combination with other reactive dyes to produce compound shades.
• Suitable for dyeing in modern, low-liquor-ratio machinery.
