Description

Reactive Violet 14 is a high-purity, reactive dye belonging to the vinyl sulfone class, primarily used for coloring cellulosic fibers. Its core value proposition lies in its excellent wash and light fastness properties, providing vibrant and durable violet hues. This product is essential for manufacturers in the textile industry seeking reliable and consistent dyeing performance for cotton, viscose, and other natural fibers.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, viscose, and other cellulosic fibers.
• Fabric Printing: Used in printing pastes for creating sharp, violet-colored patterns on cellulosic fabrics.
• Leather Coloring: Suitable for dyeing leather goods where a reactive bond with the substrate is desired for improved fastness.
• Paper Staining: Employed for specialty paper coloring applications requiring high color strength.
• Research & Development: Serves as a chemical intermediate or reference standard in laboratory and analytical settings.
