Abstract

The techniques of bleaching process of wool fibers are bleaching with reducing agents bleaching with oxidizing agents bleaching with oxidizing-reducing agents combination. In this study, different chemical bleaching methods have been developed as an alternative to the conventional bleaching method. For this purpose, peracetic acid (CH3COOOH, 30%), sodium borohydride (NaBH4), hydrogen peroxide (H2O2, 30%), potassium monopersulfate (KHSO5), sodium dichloroisocyanurate (C3Cl2N3NaO3), oxalic acid (H2C2O4), sodium perborate (NaBO3) calcium hypochlorite (Ca(ClO)2) and combination of these chemicals were performed under acidic and basic conditions. Also the environmental impacts were evaluated with measuring wastewaters COD values and surface deformations were analyzed with SEM method.
