Description

Reactive Red 11 is a high-purity, reactive azo dye specifically engineered for covalent bonding with textile fibers. This compound is valued for its excellent color fastness, bright red hue, and reliable performance in demanding dyeing processes. It is primarily utilized by manufacturers in the textile industry for dyeing and printing cellulosic fibers like cotton and viscose, as well as in research and development for specialty colorant applications.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, linen, and other cellulosic fabrics.
• Textile Printing: Used in printing pastes for creating vibrant red patterns on cellulosic textiles.
• Leather Coloring: Employed in the dyeing of leather goods to achieve durable red colors.
• Paper Coloring: Suitable for tinting paper products where a reactive bond is beneficial.
• Biomolecule Staining: Potential use in laboratory research for staining proteins or other biomolecules due to its reactive group.
• Specialty Ink Formulation: A component in the development of inks for specialized printing applications.
