Description

C.I. Reactive Blue 109 (9Cl) is a high-performance, chlorotriazine-based reactive dye renowned for its brilliant blue hue and excellent wash and light fastness properties. This dye is specifically engineered to form a covalent bond with cellulose fibers, ensuring deep, permanent coloration with minimal environmental impact due to high fixation rates. It is an essential component for textile manufacturers, dye houses, and chemical distributors serving the global market for high-quality, durable cotton and viscose fabrics. Our supply of CAS NO 61951-76-6 is backed by stringent quality control to ensure batch-to-batch consistency for industrial applications.

Application

• Exhaust Dyeing of Cellulosic Fibers: Primary application for dyeing cotton, viscose, rayon, and linen in jet, winch, and beam dyeing machines.
• Continuous Dyeing Processes: Used in pad-batch and pad-steam operations for efficient, large-scale fabric production.
• Textile Printing: Formulated for printing pastes to create sharp, vibrant patterns on cellulosic substrates.
• Leather Coloring: Employed in the dyeing of leather goods where reactive properties are beneficial.
• Technical Textiles: Suitable for dyeing industrial fabrics where colorfastness is a critical performance criterion.
• Research & Development: Serves as a reference standard and key intermediate in the development of new dye formulations and colorants.
