Description

Reactive Blue 214 is a high-performance, fiber-reactive dye belonging to the anthraquinone class, known for its brilliant blue hue and excellent wash and light fastness properties. Its primary value lies in forming a covalent bond with cellulosic fibers, ensuring deep, permanent coloration with minimal environmental impact due to high fixation rates. This dye is essential for textile manufacturers, particularly those specializing in cotton, viscose, and other natural fibers, seeking vibrant and durable shades for apparel, home textiles, and industrial fabrics. Reactive Blue 214 CAS NO 141255-32-5 is a key component in modern, eco-conscious dyeing processes.

Application

• Exhaust and continuous dyeing of cotton and cotton-blended fabrics.
• Pad-batch and pad-steam dyeing processes for viscose and rayon.
• Production of home textiles such as bed linens, towels, and curtains requiring high colorfastness.
• Dyeing of apparel fabrics for fashion and workwear where color consistency is critical.
• Coloration of industrial textiles and non-wovens.
• Used in combination with other reactive dyes to achieve a wide spectrum of navy, royal blue, and black shades.
