Description

Reactive Yellow 53 is a high-performance, water-soluble reactive dye belonging to the azo dye class. It is engineered for exceptional color yield and wash-fastness on cellulosic fibers like cotton and viscose, making it a critical component for achieving vibrant, durable yellow shades. This product is essential for textile manufacturers, dye houses, and industrial colorant producers seeking reliable and efficient dyeing solutions for apparel, home textiles, and technical fabrics.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing yarns, knits, and woven fabrics in batch processes.
• Continuous Dyeing (Pad-Batch/Pad-Steam): Used in high-volume production for uniform coloration of cotton fabrics.
• Viscose/Rayon Dyeing: Effective for dyeing regenerated cellulosic fibers to achieve bright yellow hues.
• Textile Printing: Formulated for use in printing pastes to create sharp, wash-fast patterns on cellulose-based textiles.
• Blend Dyeing (Cotton/Polyester): Can be used in combination with disperse dyes for polyester/cellulose blends.
• Leather Coloring: Applied in the dyeing of leather goods where reactive properties are beneficial.
• Paper Dyeing: Suitable for specialty paper products requiring colorfastness.

Quality Control

Our Reactive Yellow 53 is manufactured under a stringent quality management system. Every batch is tested to ensure consistent strength, shade, and reactivity, meeting the high standards required for industrial textile applications. Certificates of Analysis (COA) detailing purity, dye content, and key physical-chemical parameters are available upon request.

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 and caking.
