Description

C.I. Reactive Blue 39 is a high-performance, water-soluble reactive dye belonging to the anthraquinone class, identified by CAS NO 12225-53-5. It is engineered to form strong covalent bonds with cellulosic fibers, delivering exceptional wash and light fastness properties. This dye is essential for manufacturers in the textile industry seeking brilliant and durable blue shades on cotton, viscose, and other natural fibers.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, linen, and regenerated cellulose fibers.
• Textile Printing: Used in printing pastes for creating sharp, vibrant blue patterns on cellulosic fabrics.
• Leather Coloring: Imparts color to leather goods where reactive dye properties are beneficial.
• Paper Staining: Employed for coloring paper pulp to achieve specific blue hues.
• Research & Development: Serves as a standard or intermediate in chemical research and dye synthesis studies.
• Industrial Colorant: Potential use in coloring non-textile materials where fiber reactivity is required.
