Answer 2

Answer:

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).
