Description

Reactive Red 106 is a high-performance, water-soluble azo dye belonging to the reactive dye class, specifically engineered for covalent bonding with cellulosic fibers. Its primary value lies in delivering brilliant, durable red shades with excellent wash and light fastness properties, ensuring long-lasting color integrity in demanding applications. This dye is essential for textile manufacturers, particularly in the dyeing and printing of cotton, viscose, and other natural fibers, where consistent color yield and process reliability are critical for quality and efficiency.

Application

• Exhaust Dyeing of Cotton: For batch dyeing processes of yarn, knitwear, and woven fabrics, offering high fixation and reproducibility.
• Continuous Dyeing of Cellulosics: Applied in pad-batch, pad-steam, and pad-dry thermofix processes for uniform coloration.
• Textile Printing: Used in pigment printing formulations for sharp, vibrant prints on cotton and viscose substrates.
• Leather Coloring: Imparts rich, stable red hues to finished leather goods.
• Paper Dyeing: Provides coloration for specialty papers requiring good wet fastness.
• Biomaterial Staining: Potential use in laboratory settings for histological staining due to its reactive nature with specific substrates.

Quality Control

Our production of Reactive Red 106 adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including color strength, shade, solubility, and fixation rate. Certificates of Analysis (COA) detailing purity, impurity profiles, and physical specifications are provided and can be tailored to meet specific customer or regulatory requirements.

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 packaging is sealed after use to prevent moisture absorption and caking.
