Abstract:The aim of the presented research was to investigate the impact of different dyeing procedures (conventional two-baths and one-bath) and dye-bathsć pH (acidic and alkaline) on the exhaustion of five disperse dyestuffs, differing in colour (yellow, red, blue, violet and black). The dyeing of polyester thread was carried-out at two concentrations (1 and 3%). The concentration of dye residual in dye-bath effluents were determined by absorbance measurement, followed by colourimetrical evaluation of dyed samples, and colour differencescalculation. The obtained results indicating superior dye exhaustion throughout alkaline one-bath procedure in comparison to conventional polyester dyeing that affect also on reduction of dyeing time, amount of dye-bath wastewaters, and energy consumption.
