A single-stage preparatory process for cotton fabrics, based on a self emulsifiable solvent-assisted system using sodium hypochlorite has been investigated using a second- order response surface design. The proposed process works at a low temperature (40°C) and thus leads to a considerable energy savings. The properties of single-stage bleached fabrics are comparable with those of conventionally bleached fabrics.
