SPECTRA “VS” COLOR (VINYL SULPHONE TYPE DYES)

These are vinyl sulphone-based reactive dyes widely used for dianisidine, ortho-dianisidine dyeing, and printing of cellulose fibres due to their very good fastness properties. Ortho-dianisidine dyes have good features such as good solubility even in the presence of alkali, very good fastness properties, and the ability to be applied both by exhaust and padding methods. They possess less affinity, hence providing very good leveling properties, and are suitable for resist and discharge dianisidine printing very effectively. These dyes are applied by the exhaust method at the optimum temperature of 60-65^°C.
