20.500.12556/DKUM-26219 Colour of polyester thread, in regard to different dyeing procedures and dye-bathsć ph 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. polyester sewing dyeing disperse dyestruffs colourimetry true false false Angleški jezik Angleški jezik Neznano 2012-05-31 12:14:22 2012-05-31 12:14:22 2022-04-15 03:41:08 2024-01-03 03:22:19 2008 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677 12415510 URN:SI:UM:DK:TDVLGCB9 http://www.autex2008.it/cd/files/posters/2_480f270b187a1.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=35168 Fakulteta za strojništvo 0 0 0
