Description

C.I.Reactive Orange 41 is a high-performance, water-soluble reactive dye belonging to the azo chemical class. It is engineered to form a strong covalent bond with cellulosic fibers, delivering excellent wash and light fastness properties. This dye is essential for textile manufacturers and dye houses seeking vibrant, durable orange to red-orange shades on cotton, viscose, and other natural fabrics.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cellulosic fibers like cotton, linen, and rayon.
• Fabric Printing: Used in printing pastes for creating sharp, colorfast patterns on natural fiber textiles.
• Garment Dyeing: Suitable for dyeing finished apparel and knitwear, ensuring uniform and deep coloration.
• Industrial Yarn Coloring: Applied in the coloration of sewing threads, cords, and other industrial yarns requiring high durability.
• Leather Coloring: Used for dyeing leather goods where a reactive bond with protein fibers is beneficial.
• Paper Staining: Employed in specialty paper production for achieving colored paper stock.
