Description

Reactive Violet 17 is a high-purity, reactive dye belonging to the vinyl sulfone class, widely recognized for its brilliant violet hue and excellent fastness properties. This product is engineered to deliver consistent color strength and reliable performance in demanding industrial dyeing processes. It is primarily utilized by textile manufacturers and dye houses for the coloration of cellulosic fibers like cotton and viscose, offering superior wash and light fastness.

Application

• Exhaust dyeing of cotton yarn and knitted fabrics.
• Continuous pad-dyeing and pad-steam processes for woven cellulosic textiles.
• Printing applications on cotton and viscose substrates.
• Dyeing of regenerated cellulose fibers, including lyocell and modal.
• Used in combination with other reactive dyes to achieve a wide spectrum of deep and bright shades.
• Application in the production of home textiles, such as bed linens and towels, requiring high colorfastness.
