Description

Reactive Orange 44 is a high-performance, fiber-reactive dye belonging to the azo dye class, identified by CAS No. 61969-13-9. It is valued for its ability to form covalent bonds with cellulose fibers, resulting in excellent wash and light fastness properties. This dye is essential for manufacturers in the textile industry seeking vibrant and durable orange to red-orange shades on cotton, viscose, and other cellulosic materials.

Application

• Primary dyeing and printing of cotton fabrics for apparel and home textiles.
• Coloration of viscose (rayon) and other regenerated cellulose fibers.
• Used in the exhaust dyeing process for yarns and knitted goods.
• Application in continuous dyeing ranges for large-volume fabric production.
• Suitable for use in textile printing pastes to create patterned designs.
• May be used for dyeing blends of cellulose with synthetic fibers under appropriate conditions.
