Description

Reactive Red 84 is a high-purity, reactive azo dye belonging to the vinyl sulfone class, known for its bright red color 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 dyed textiles. This product is essential for manufacturers in the textile industry seeking reliable and vibrant coloration for cotton, viscose, and other natural fibers.

Application

• Textile Dyeing: Primary application for the exhaust and continuous dyeing of cotton, viscose, and other cellulosic fibers.
• Printing Pastes: Used in the formulation of printing inks and pastes for textile printing applications.
• Leather Coloring: Employed in the dyeing of leather goods to achieve durable and vibrant red shades.
• Paper Staining: Suitable for the coloration of specialty papers where high color strength is required.
• Research & Development: Serves as a reference standard or intermediate in chemical synthesis and dye research laboratories.
