Description

Reactive Blue 222 is a high-performance, fiber-reactive dye belonging to the anthraquinone class, known for its brilliant blue hue and excellent fastness properties. Its primary value lies in providing vibrant, wash-fast, and light-fast coloration for cellulosic fibers like cotton and viscose, making it a cornerstone for textile manufacturers. This dye is essential for industries requiring durable and consistent blue shades, particularly in textile dyeing and printing operations for apparel, home furnishings, and industrial fabrics. Reactive Blue 222 CAS NO 93051-44-6 offers reliable performance in exhaust and continuous dyeing processes, ensuring high fixation rates and minimal effluent.

Application

• Textile Dyeing: Primary application for exhaust and pad-batch dyeing of cotton, linen, rayon, and other cellulosic fabrics to achieve brilliant blue shades.
• Textile Printing: Used in printing pastes for creating sharp, defined blue patterns on garments and home textiles with excellent wash fastness.
• Garment Manufacturing: Ideal for dyeing finished knitwear, t-shirts, denim, and other apparel items requiring consistent color depth and durability.
• Home Furnishings: Applied in the coloration of bed linens, towels, curtains, and upholstery fabrics where colorfastness to light and washing is critical.
• Industrial Textiles: Suitable for dyeing technical textiles, canvas, and webbing where functional performance and color retention are important.
• Yarn Dyeing: Used for package and hank dyeing of cotton and blended yarns intended for weaving and knitting.
