Description

Reactive Blue 52 is a high-purity, reactive anthraquinone dye used for the covalent coloration of cellulosic fibers. This product is essential for achieving brilliant, wash-fast blue shades in textile manufacturing. It is primarily needed by dye houses and textile chemical suppliers for dyeing and printing cotton, viscose, and other cellulose-based materials.

Application

• Exhaust dyeing of cotton yarns and fabrics.
• Continuous pad-steam dyeing processes for cellulosic textiles.
• Textile printing applications for sharp, defined blue patterns.
• Coloration of viscose rayon and other regenerated cellulose fibers.
• Used in formulations for producing specific navy and royal blue shades.
• Potential use in research and development of new dye formulations.
