Description

Reactive Violet 22 is a high-performance, water-soluble reactive dye belonging to the vinyl sulfone class, designed for covalent bonding with cellulosic fibers. Its primary value lies in producing vibrant, wash-fast violet to blue-violet shades with excellent reproducibility and good all-around fastness properties. This dye is essential for textile manufacturers and dye houses specializing in the exhaust and continuous dyeing of cotton, viscose, and other cellulose-based fabrics, as well as for printing applications.

Application

• Exhaust dyeing of cotton yarn and knitted fabrics.
• Pad-batch and pad-steam continuous dyeing of woven cellulose fabrics.
• Textile printing on cotton and viscose substrates.
• Dyeing of regenerated cellulose fibers like lyocell and modal.
• Used in combination with other reactive dyes to achieve a broad spectrum of shades.
• Applicable in garment dyeing processes for consistent coloration.
