TANACTIVE 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.
