(
Explanation:
A fair amount of neutral salts, such as sodium sulfate or sodium chloride, are used to assist the dyeing process. Their function varies depending on the dye class. For example, in direct dyeing, neutral salts increase the aggregation of the dyes inside the fiber pores and render the dye less hydrophilic (Shore, 1995). In acid dyeing, salts function as retarders, giving more level dyeing results. Depending on the requirements of the specific dye, 10–20% or more salt on weight of fabric is not uncommon. However, as dyeing auxiliaries, salts are carefully washed out once the dyeing process has been completed, with the effect of added loading of the waste water. Additionally, most dyeing processes need either alkaline or acid conditions for good results and neutralization of the spent dye bath leads to further salination of the waste stream.
