Description

Reactive Red 23 is a high-purity, reactive azo dye widely used in industrial textile coloration. Its primary value lies in its ability to form a covalent bond with cellulose fibers, resulting in exceptional wash and light fastness properties. This product is essential for manufacturers in the textile industry seeking vibrant, durable red shades on cotton, viscose, and other cellulosic materials. Our supply is characterized by consistent quality and batch-to-batch uniformity to meet rigorous production demands.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, rayon, and other cellulosic fibers.
• Printing Pastes: Used in the formulation of printing inks and pastes for textile printing applications.
• Leather Coloring: Employed for dyeing leather goods where good fastness properties are required.
• Paper Staining: Suitable for coloring paper and paper-based products.
• Research & Development: Serves as a reference standard or intermediate in chemical and dyestuff research.
• Specialty Applications: Potential use in the coloration of non-conventional substrates requiring reactive dye chemistry.
