Description

Reactive Orange 70 is a high-performance, water-soluble reactive dye belonging to the azo dye class, identified by CAS No. 61969-18-4. It is valued for its excellent color fastness, bright hue, and strong covalent bonding with cellulosic fibers, ensuring vibrant and durable coloration. This dye is essential for manufacturers in the textile industry seeking reliable and efficient coloring solutions for cotton, viscose, and other natural fibers.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cellulosic fibers like cotton, linen, and viscose to achieve orange shades.
• Fabric Printing: Used in printing pastes for direct and discharge printing on natural fiber fabrics.
• Garment Dyeing: Suitable for dyeing finished knitwear and woven garments due to its good leveling and migration properties.
• Industrial Textiles: Coloration of technical textiles, including those used in home furnishings and automotive interiors where wash and light fastness are critical.
• Yarn Dyeing: Effective for package and hank dyeing of cotton and blended yarns.
• Leather Coloring: Application in dyeing leather where reactive properties can be utilized for certain pretreated substrates.
