Description

Procion Blue H-5R is a reactive dye belonging to the monochlorotriazine class, widely recognized for its vibrant blue color and excellent wash-fastness properties. Its primary value lies in its ability to form covalent bonds with cellulosic fibers, ensuring durable and brilliant coloration that resists fading. This dye is essential for manufacturers in the textile industry, particularly for dyeing and printing cotton, viscose, and other natural fibers, as well as for research and development in color chemistry.

Application

• Exhaust dyeing of cotton and other cellulosic fabrics.
• Continuous dyeing and pad-batch processes for textiles.
• Textile printing applications for sharp, defined patterns.
• Coloration of viscose rayon and linen.
• Research and development of new dye formulations and processes.
• Educational purposes in textile chemistry and dye application labs.
