Description

Reactive Yellow 105 is a high-performance, bifunctional reactive dye designed for demanding textile coloration processes. Its primary value lies in delivering brilliant, wash-fast yellow shades with excellent reproducibility and high fixation rates on cellulosic fibers. This product is essential for textile manufacturers and dye houses seeking reliable and efficient coloration for cotton, viscose, and other natural fibers. Its robust performance makes it suitable for continuous and exhaust dyeing applications where color consistency is paramount.

Application

• Exhaust dyeing of cotton yarn and knitted fabrics.
• Continuous pad-steam and pad-batch dyeing of woven cotton.
• Coloration of viscose rayon and other regenerated cellulosic materials.
• Used in combination with other reactive dyes to achieve a wide spectrum of shades.
• Suitable for garment dyeing and other piece-dyeing operations.
• Application in the printing of cellulosic textiles.

Quality Control

Our Reactive Yellow 105 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including shade, strength, solubility, and fixation properties to meet the specifications required for industrial textile applications. Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics are available upon request 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 ambient temperature (15-25°C). Keep away from strong oxidizing agents and incompatible materials. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption and caking.
