Description

Reactive Orange 13 is a high-purity, reactive dye belonging to the azo dye class, identified by CAS No. 12225-85-3. It is engineered for covalent bonding with cellulosic fibers, providing exceptional color fastness and wash resistance. This product is essential for textile manufacturers and dye houses seeking vibrant, durable orange hues on cotton, viscose, and other natural fabrics.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cellulosic fibers like cotton, linen, and rayon.
• Fabric Printing: Used in printing pastes for creating sharp, colorfast patterns on natural fiber textiles.
• Leather Coloring: Imparts durable orange shades to leather goods in tanneries.
• Paper Staining: Employed for coloring specialty papers and paper products where high wet fastness is required.
• Research & Development: Serves as a standard or intermediate in chemical research and dye synthesis studies.

Quality Control

Our Reactive Orange 13 is manufactured under a stringent quality management system. Every batch is tested to ensure consistent strength, shade, and reactivity. Key parameters such as dye content, solubility, and fixation rate are verified. A Certificate of Analysis (COA) detailing purity and performance specifications is provided with each shipment to guarantee it meets the demands of industrial dyeing processes.

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. The product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture absorption, which can affect performance.
