The dyeing efficiency of these systems were compared with those of the conventional system using sodium hydrosulphite. Results of the color strength of the obtained dyeings are higher than those for hydrosulphite. Furthermore, dyeings obtained with the new reducing systems exhibit very good fastness properties. Rubbing fastness on polyester dyed with indigo is superior to that on cotton. %U https://absb.journals.ekb.eg/article_11645_299942d2a366286f2e4be2fddc78dc09.pdf
