Abstract

Indigo, one of the oldest dyes, has a very important role for the textile sector. It is primarily used to dye cotton clothes, and blue jeans and over one billion pairs of jeans around the world are dyed blue with indigo. Although Sodium Hydrosulfite (Na2S2O4) is used as a reducing agent in most indigo dyeing processes, it is environmentally unfavorable because of the resultant contaminated toxic wastewater. In addition, the color fastnesses of dyed samples using Na2S2O4 as reducing agent are not good enough.
