Description

Reactive Yellow 84 is a high-performance, water-soluble reactive dye designed for demanding coloration processes. Its primary value lies in its excellent fixation properties and bright, consistent yellow hue, which is crucial for achieving high-quality, reproducible results in industrial applications. This product is essential for manufacturers in the textile and leather industries who require durable, wash-fast, and light-fast coloring for cellulosic fibers such as cotton, viscose, and linen.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cellulosic fibers like cotton, viscose, and linen, providing excellent wash and light fastness.
• Leather Coloring: Used for dyeing leather goods, offering vibrant and durable color penetration.
• Pad-Batch Dyeing: Suitable for cold pad-batch dyeing processes, valued for its high reactivity and fixation yield at low temperatures.
• Printing Pastes: A key component in the formulation of printing pastes for textile printing, ensuring sharp definition and color consistency.
• Industrial Fabric Production: Employed in dyeing fabrics for workwear, home textiles, and other industrial fabrics where color durability is critical.
• Yarn Dyeing: Effective for package and beam dyeing processes for cellulosic yarns.

Quality Control

Our Reactive Yellow 84 is manufactured under a stringent quality management system. Every batch undergoes rigorous testing for critical parameters including color strength, shade, solubility, and fixation properties to ensure consistency and performance. A Certificate of Analysis (COA) detailing purity, physical properties, and application test results is provided with each shipment to guarantee it meets your specific technical 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). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials.
