Applications of TiO2, ZnO and Ag Nanomaterials to Denim Fabric

In previous studies much research has reported the determination of applications of TiO2 (rutile and anatase), ZnO and Ag nanomaterials onto various textile surfaces, but in this study for the first time application to denim fabric and testing of the finished fabric for antimicrobial activities of these nanomaterials was investigated. The presence of nanoparticles on dyed denim fabric surfaces was confirmed by Scanning Electron Microscope (SEM). The nanomaterial-impregnated denim fabric (100% cotton) showed significant antibacterial activity against Staphylococcus aureus, Escherichia coli and Escherichia coli isolated from pasta. Additionally, the UV tests indicated excellent improvement in the UV absorbing activity of the TiO2 (rutile and anatase), ZnO and Ag nanomaterial-treated fabrics.
