Description

Reactive Orange 84 is a high-performance, water-soluble reactive dye designed for covalent bonding with cellulosic fibers. This product matters for its excellent color fastness, brilliant hue, and efficient fixation properties, ensuring vibrant and durable coloration. It is primarily needed by textile manufacturers and dye houses specializing in cotton, viscose, and other cellulose-based fabrics, where consistent quality and reliable performance are critical for commercial production.

Application

• Exhaust dyeing of cotton yarn and knitted fabrics.
• Continuous pad-dyeing and pad-batch processes for woven cotton textiles.
• Dyeing of viscose (rayon) and other regenerated cellulose fibers.
• Used in the coloration of cellulosic blends where a uniform shade is required.
• Suitable for applications demanding high wet fastness and light fastness properties.
• Employed in the production of home textiles, apparel, and industrial fabrics.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
