Description

Reactive Orange 24 is a synthetic, water-soluble reactive dye belonging to the azo dye class, identified by CAS No. 12236-98-5. It is engineered to form a covalent bond with cellulosic fibers, providing 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 natural fibers.

Application

• Exhaust Dyeing of Cellulosic Fibers: Primary application for dyeing cotton, rayon, linen, and hemp in batch processes.
• Continuous Dyeing Processes: Used in pad-batch and pad-steam operations for uniform coloration of fabrics.
• Yarn Dyeing: Effective for coloring cotton and viscose yarns for weaving and knitting.
• Garment Dyeing: Suitable for dyeing finished apparel items to achieve consistent color.
• Union Dyeing: Can be applied in mixtures with other dyes for coloring blended fabrics.
• Technical Textiles: Used for coloring industrial textiles where colorfastness is a critical requirement.

Quality Control

Our Reactive Orange 24 is manufactured under a strict quality management system. Every batch is tested to ensure consistent strength, shade, and reactivity. Key parameters including color strength, solubility, fixation rate, and fastness properties are verified. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment to guarantee it meets the required industrial standards.

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). Keep away from strong oxidizing agents and excessive heat. The product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent caking.
