Description

Reactive Blue 182 is a high-performance, fiber-reactive dye belonging to the anthraquinone class, specifically engineered for covalent bonding with cellulosic fibers. Its primary value lies in delivering brilliant, wash-fast blue shades with excellent reproducibility and good all-around fastness properties. This dye is essential for textile manufacturers and dye houses specializing in the coloration of cotton, viscose, and other cellulose-based materials, where consistent color yield and process reliability are critical.

Application

• Exhaust dyeing of cotton yarns and fabrics for apparel and home textiles.
• Continuous pad-dyeing and pad-steam processes for woven and knitted cellulosic goods.
• Dyeing of viscose rayon and lyocell fibers to achieve vibrant blue hues.
• Used in combination with other reactive dyes to produce a wide spectrum of compound shades, including greens and navies.
• Suitable for application in modern, low-salt or salt-free reactive dyeing processes to meet environmental standards.
• Formulation of liquid or powder dye preparations for automated dosing systems in large-scale production.

Quality Control

Every batch of Reactive Blue 182 is subjected to a comprehensive suite of analytical tests to ensure it meets stringent quality and performance benchmarks for the textile industry. Our quality assurance protocol includes verification of color strength, shade, solubility, and fixation properties against established standards. Certificates of Analysis (COA) detailing purity, physical properties, and application performance are available upon request to support your quality management systems.

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 each use to prevent moisture absorption and caking.
