Description

Benzenesulfonic acid, 5-[[4-[bis(2-hydroxyethyl)amino]-6-methoxy-1,3,5-triazin-2-yl]amino]-2-[2-[4-[[4-methoxy-6-[(2-sulfoethyl)amino]-1,3,5-triazin-2-yl]amino]-2-sulfophenyl]ethenyl]-, sodium salt, compd. with 2-aminoethanesulfonic acid mo is a high-performance, water-soluble anionic dye belonging to the reactive dye class, specifically engineered for demanding coloration applications. Its complex molecular structure, featuring multiple sulfonic acid groups and reactive triazine moieties, provides exceptional substantivity, brilliant color yield, and excellent fastness properties on cellulosic fibers. This product is essential for manufacturers in the textile industry seeking vibrant, wash-fast, and lightfast dyes for cotton, viscose, and other natural fibers.

Application

• Textile Dyeing: Primary application for the exhaust and continuous dyeing of cotton, linen, viscose, and other cellulosic fabrics.
• Reactive Dye Formulation: A key component in the production of high-quality liquid or powder reactive dye formulations for industrial use.
• Garment and Yarn Dyeing: Used for achieving deep, uniform, and fast colors in yarn dyeing and garment dyeing processes.
• Printing Pastes: Suitable for use in textile printing pastes, offering sharp print definition and excellent fixation.
• Technical Textiles: Applied in the coloration of technical textiles where color consistency and durability are critical.
• Research & Development: Serves as a reference standard or intermediate for R&D in novel dye synthesis and performance testing.
