He Brand Dyes

These HE Brand Dyes are suitable for dyeing cotton and other cellulosic materials. These dyes possess significantly higher exhaustion and fixation efficiency, which results in appreciable cost reduction, in comparison to conventional reactive dyes. The high fixation and good build up are of particular importance when dyeing polyester/cellulosic blends and wash liquor : goods ratio is quite high. 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 to everybody. This facilities quicker wash off and efficient soaping. The improved stability of HE dyes gives improved batch to batch consistency. Exhaustion of HE dyes can be controlled by salt addition and temperature to give level dyeing before alkali addition.
The other useful features of HE dyes are as under:
Excellent build-up in high as low liquor: Goods ratios.
The high fixation is of particular importance when dyeing polyester/ cellulose blend when liquor/goods ratio is quite high. Under the circumstances, conventional reactive dyes show low dyeing efficiency and poor build-up.
Excellent reproducibility.
Wide applicability on yarn, piece material, loose stock and garments.
Wide choice of equipment to suit particular application.
