Description

Reactive Red 89 is a high-purity, reactive azo dye used for coloring cellulosic fibers. This compound is valued for its excellent color fastness, bright red hue, and strong covalent bond formation with textile substrates, ensuring wash and light resistance. It is primarily required by manufacturers in the textile dyeing and printing industries for applications on cotton, viscose, and other natural fibers.

Application

• Primary dyeing of cotton and other cellulosic fibers in exhaust and continuous processes.
• Textile printing applications for producing vivid red shades on fabrics.
• Used in the coloration of viscose rayon and blended fabrics.
• Potential application in the dyeing of leather and paper where reactive dyes are specified.
• Employed in research and development for creating new dye formulations and color blends.
