Description

C.I. Reactive Violet 6 is a high-purity, reactive vinyl sulfone dye belonging to the anthraquinone chemical class, widely recognized for its brilliant violet hue and excellent fastness properties. This product is engineered for superior dyeing performance, offering exceptional color yield, reproducibility, and compatibility with modern industrial processes. It is an essential component for manufacturers in the textile industry requiring durable and vibrant coloration on cellulosic fibers such as cotton and viscose.

Application

This reactive dye is primarily utilized in industrial dyeing and printing processes where colorfastness and brilliance are critical. Key application areas include:

• Exhaust Dyeing of Cellulosic Fibers: For dyeing cotton, linen, hemp, and rayon in batch processes like jet, overflow, and beam dyeing.
• Continuous Dyeing: Applied in pad-batch, pad-steam, and pad-dry thermofix processes for high-volume fabric production.
• Textile Printing: Used in pigment printing formulations for creating sharp, wash-fast patterns on fabrics.
• Leather Coloring: For dyeing leather goods where deep, even penetration and lightfastness are required.
• Paper Dyeing: In the coloration of specialty papers, including decorative and security papers.
• Biomolecule Staining: Potential use in laboratory settings for staining biological specimens in microscopy.
