Description

Reactive Violet 2 is a synthetic anthraquinone-based reactive dye designed for covalent bonding with textile fibers. This compound is valued for its ability to produce vibrant violet hues with excellent wash and light fastness properties on cellulosic materials. It is primarily utilized by manufacturers in the textile dyeing and printing industries seeking consistent, high-quality coloration for cotton, viscose, and other natural fibers.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, rayon, and other cellulosic fabrics.
• Textile Printing: Used in printing pastes for creating sharp, durable violet patterns on garments and home textiles.
• Leather Coloring: Employed in the dyeing of leather goods to achieve uniform and fast violet colors.
• Paper Staining: Suitable for specialty paper coloring where a reactive bond with cellulose fibers is desired.
• Research & Development: Serves as a reference standard or intermediate in chemical research and dye synthesis laboratories.
