Description

Reactive Red 174 is a high-performance, water-soluble azo dye belonging to the reactive dye class, designed for covalent bonding with textile fibers. This compound is valued for its excellent color fastness, brilliant red hue, and efficient fixation properties under standard dyeing conditions. It is primarily used by manufacturers in the textile industry for dyeing and printing cellulosic fibers such as cotton, viscose, and linen.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton 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 where good wash and light fastness are required.
• Paper Staining: Suitable for coloring paper products where a strong, reactive red color is needed.
• Research & Development: Serves as a chemical intermediate or reference standard in dye chemistry research.
