V. S. Dyes

V.S. Dyes are reactive dyes of Vinyl sulfone system. Since the combination of Vinylsulfone group with cellulosic fibers is stable to acid hydrolysis, the stability of the dyed substrate with the lapse of time is excellent. Also, after completion of dyeing, the substantivity of hydrolyzed dyes is considerably low, so that the washing off property of unfixed dyes is excellent. Deoton dyes have wide range of dyeing temperature and are highly reproducible in exhaust dyeing. Also, by the improvement of alkali stability in continuous and cold pad-batch dyeing, and by that of stability of printing paste, highly reproducible dyeing can be obtained in continuous dyeing as well as printing. In addition, Deoton dyes have excellent all-round wet fastness properties.
