Description

Reactive Yellow 35 is a high-performance, water-soluble reactive dye belonging to the azo dye class, widely recognized for its vibrant yellow hue and excellent fastness properties. Its primary value lies in its ability to form a covalent bond with cellulose fibers, ensuring exceptional wash and light fastness in the final textile product. This dye is essential for manufacturers in the textile industry, particularly for dyeing and printing cotton, viscose, and other cellulosic materials, where consistent color yield and durability are critical.

Application

• Exhaust dyeing of cotton yarns and fabrics.
• Continuous pad-batch and pad-steam dyeing processes for cellulosic textiles.
• Textile printing applications on cotton and viscose.
• Dyeing of hemp and linen for specialty fabrics.
• Used in the production of home textiles like bed linens and curtains.
• Coloration of viscose for apparel and fashion garments.

Quality Control

Our Reactive Yellow 35 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including color strength, shade, solubility, and fixation properties. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and application performance is provided with each shipment to support your quality assurance protocols.

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 incompatible materials. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
