Description

Procion Red Mx-5B is a highly reactive, dichlorotriazine-based fiber-reactive dye renowned for its brilliant red color and excellent wash-fastness properties. This product is essential for achieving vibrant, durable coloration on cellulosic fibers such as cotton, viscose, and linen. It is a critical component for textile manufacturers, dye houses, and research laboratories focused on developing high-quality, colorfast fabrics and materials.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, rayon, and other cellulosic fabrics.
• Printing: Used in textile printing pastes for creating sharp, bright red patterns with good fixation.
• Research & Development: Serves as a key intermediate or reference standard in the development of new dye formulations and coloration processes.
• Leather Coloring: Applied for dyeing leather goods where a strong, reactive red shade is required.
• Paper Staining: Employed in specialty paper production for tinting and coloration.
• Educational Use: Utilized in academic and industrial training for demonstrations of reactive dye chemistry and application techniques.
