Description

Reactive Red 45 is a high-purity, reactive azo dye specifically engineered for demanding coloration processes. Its primary value lies in its excellent reactivity and colorfastness, providing vibrant and durable red shades on cellulosic fibers. This product is essential for manufacturers in the textile industry seeking reliable and consistent dyeing performance for cotton, viscose, and other natural fabrics.

Application

• Primary dyeing of cotton and viscose fibers and fabrics.
• Coloration of cellulosic textiles in exhaust and continuous dyeing processes.
• Used in the production of dyed yarns for weaving and knitting applications.
• Formulation of specialty dye liquors for consistent batch-to-batch results.
• Potential use in the coloration of paper and leather, subject to specific grade suitability.

Quality Control

Our Reactive Red 45 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against stringent in-house specifications for critical parameters such as color strength, solubility, and reactive group content. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance characteristics is provided with every shipment.

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 original container is properly sealed after use to prevent moisture absorption and caking.
