Description

Trisodium 2-[[6-[[4-Fluoro-6-(Methylphenylamino)-1,3,5-Triazin-2-Yl]Amino]-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo]Naphthalene-1,5-Disulphonate is a high-performance, water-soluble anionic dye belonging to the reactive dye class. It matters for its excellent color fastness, particularly to washing and light, and its ability to form covalent bonds with cellulosic fibers. This product is essential for industrial manufacturers seeking vibrant and durable coloration in textiles. Its specific structure is engineered for high fixation rates and brilliant shades.

Application

• Reactive Dyeing of Cellulosic Fibers: Primary application for dyeing cotton, viscose, rayon, and linen in exhaust, pad-batch, and continuous dyeing processes.
• Textile Printing: Used in the formulation of printing pastes for high-definition, wash-fast prints on natural fiber fabrics.
• Leather Coloring: Employed for dyeing leather goods where deep penetration and good fastness properties are required.
• Paper Dyeing: Suitable for coloring paper products, providing strong, bleed-resistant coloration.
• Ink Formulation: A key component in the manufacture of specialty inks for non-impact printing and other applications requiring water-soluble dyes.
• Research & Development: Serves as a chemical intermediate or reference standard in R&D laboratories for developing new colorants and studying dyeing mechanisms.
