Description

C.I. Reactive Red 3 is a high-performance, water-soluble reactive dye belonging to the azo chemical class, widely recognized for its bright red hue and excellent colorfastness properties. This dye is engineered to form a covalent bond with cellulosic fibers, ensuring superior wash and light fastness in the final textile product. It is an essential component for dyeing and printing cotton, viscose, and other natural fibers, serving the needs of the global textile, garment, and technical fabric industries.

Application

• Primary exhaust dyeing and continuous dyeing of cotton and viscose fabrics.
• Textile printing applications, including screen and rotary printing.
• Coloration of cellulosic yarns and threads for the garment industry.
• Used in the production of home textiles such as bed linens, towels, and curtains.
• Potential application in the dyeing of leather and paper, depending on formulation.
• Manufacture of colored non-woven and technical textiles.
