May you kindly clarify on what you mean. Do u mean using nanotechnology to reduce the amount of dyes used during the dyeing process or you mean using nanotechnology to remove dyes from textile wastewater after the dyeing process?

I agree with M. Lloyd Ndlovu, I agree with Monsieur. It should be specified if we want to optimize the exhaustion of the dye bath or to remove dyes from textile wastewater .

Thanks dear Dr. Lloyd Ndlovu and dr. Neji Ladhari , I worked in removed textile dye, but know i need to decrease the used dye as economic method with addition nano material to increase the fixation of dye in less amount of dye
