Reactive He Beand Dyes

These dyes are high exhaust type based on mono-chlorotriazene and are especially suitable for exhaust dyeing. They are characterized by excellent yield at low as well as high liquor ratio and are of special importance for cotton yarn, knits and fabrics. They are widely used for dyeing cellulosic component in the polyester - cellulosic blends. These dyes possess significantly higher exhaustion and fixation efficiency, which results in appreciable cost reduction, in comparison to conventional reactive dyes. Due to higher fixation of HE dyes, the drained and wash liquors after dyeing contain much less quantity of unfixed dyes, in comparison to conventional reactive dyes, which is of interest when pollution control is a major concern today.
