Both 2% and 5% omf dyeings of polycotton fabric which had been produced using commercial grade disperse dyes and reactive dyes can be washed-off using two, novel processes that utilise polyamide beads. The bead wash-off processes provided dyeings that were of similar colour, depth of shade and fastness compared to those which had been subjected to a conventional reduction clearing process in the case of the disperse dyes and a conventional wash-off in the case of the reactive dyes. The wastewater obtained from the bead wash-off of disperse dyes contained considerably lower concentrations of chloride ion as well as lower TDS compared to that secured using a conventional reduction clearing process, which was attributed to the beads having adsorbed vagrant chloride ions. In contrast, bead wash-off of reactive dyes did not reduce either the chloride ion concentration nor TDS content of the wastewater produced, because of the swamping effect of the very high chloride ion concentration. Bead wash-off also enabled significant reductions in both heat energy and water consumption to be achieved.

使用商业级分散染料和活性染料生产的涤棉织物的2％和5％omf染色都可以使用两种利用聚酰胺珠粒的新颖方法洗掉。与在分散染料的情况下进行常规还原清除工艺的染料相比，在分散染料的情况下进行常规还原清除工艺的珠子冲洗工艺所提供的染料具有相似的颜色，色泽深度和牢度。活性染料。与使用常规还原清除工艺所确保的废水相比，从珠粒洗去分散染料获得的废水中所含氯离子的浓度要低得多，而TDS则要低得多，这归因于珠粒已吸附了流离失所的氯离子。相比之下，由于非常高的氯离子浓度会产生沼泽效应，因此洗掉活性染料的珠粒不会降低所产生废水中的氯离子浓度或TDS含量。珠粒的冲洗还可以显着减少热能和水的消耗。
