Investigation of the wettability and washing,perspiration and rubbing fastness of denim fabric in the presence of some nano-metal oxides and nano-Ag

In this study, we analysed finished denim fabric for hydrophobic wettability, washing, perspiration and rubbing fastness of TiO₂ (anatase), CuO, ZnO and Ag nanomaterials. The presence of nanoparticles on dyed denim fabric surfaces was confirmed by Scanning Electron Microscope and EDAX. According to the contact angle, washing, perspiration and rubbing fastness measurements, these nanomaterials were improved surface properties of denim fabric. The coatings made by these nanomaterials increased hydrophilic or hydrophobic properties by changing wetting capability of denim fabric surface. Additionally, nano-metal oxide particles were improved fastness values. The highest contact angle and fastness values were found on denim fabric treated with nano-TiO₂ (anatase) and the lowest contact angle and fastness values were found for denim fabric plated with nano-Ag.
