Description

C.I. Reactive Blue 162 is a high-performance, water-soluble reactive dye belonging to the vinyl sulfone class, known for its bright blue shade and excellent wet fastness properties. Its primary value lies in its ability to form a strong covalent bond with cellulosic fibers, ensuring vibrant, durable coloration that resists washing and light. This dye is essential for textile manufacturers and dye houses specializing in the continuous and exhaust dyeing of cotton, viscose, and other natural fibers, as well as for printing applications.

Application

• Exhaust Dyeing of Cotton: For batch dyeing processes in jiggers, winches, and jet dyeing machines, offering good levelness and reproducibility.
• Continuous Dyeing of Cellulosics: Applied in pad-steam and pad-dry-chemical pad-steam processes for high-volume, uniform fabric coloration.
• Textile Printing: Used in reactive printing pastes for sharp, bright designs on cotton and viscose fabrics.
• Dyeing of Viscose/Rayon: Provides excellent build-up and shade consistency on regenerated cellulose fibers.
• Union Dyeing: Suitable for dyeing cotton in blends with polyester or other synthetic fibers using appropriate dye combinations.
• Garment Dyeing: Effective for dyeing finished cotton garments, offering good penetration and fastness.

Quality Control

Our production of C.I. Reactive Blue 162 adheres to stringent quality management protocols to ensure batch-to-batch consistency in shade, strength, and solubility. Every lot is tested against key parameters including color strength, hue, fixation rate, and fastness properties. Certificates of Analysis (COA) detailing purity, physical properties, and performance characteristics are available upon request to support your quality assurance and production planning.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent caking or quality degradation.
