Description

C.I. Reactive Blue 168 is a high-performance, water-soluble reactive dye belonging to the vinyl sulfone class, known for its bright blue hue and excellent fastness properties. Its primary value lies in its ability to form a strong covalent bond with cellulosic fibers, ensuring superior wash and light fastness in the final textile product. This dye is essential for manufacturers in the textile industry requiring consistent, vibrant coloration for cotton, viscose, and other natural fibers.

Application

• Exhaust dyeing and continuous dyeing of cotton and viscose fibers.
• Printing applications on cellulosic fabrics to achieve sharp, bright blue prints.
• Used in the dyeing of hemp, linen, and other natural cellulosic materials.
• Formulation of dye mixtures for producing a range of green and navy shades.
• Application in the dyeing of cotton yarn for subsequent weaving or knitting.
• Suitable for use in modern, low-salt or salt-free reactive dyeing processes to reduce environmental impact.
