The focus of this study was to characterize three industrially-prepared (via the sulphate synthesis process) nano-TiO₂ colloidal dispersions with the intention to elucidate their role on the hydrophilicity as well as UV shielding ability when applied onto polyamide fabric. Transmission electron microscopy (TEM) and UV spectrophotometry of the selected dispersions proved the presence of TiO₂ nanoparticles of different shapes and sizes, as well as its imposing absorption capability within the UV region. In addition, TiO₂ dispersions in three concentrations accompanied by selected chemicals and auxiliaries were applied on polyamide fabrics according to standard exhaustion procedure. Scanning electron microscopy (SEM) was adopted in order to analyse the morphological structure of nano-TiO₂-upgraded PA fabrics. Furthermore, the UV-protective ability and hydrophilic properties were evaluated. The gained results show excellent blocking properties against UV-rays (UPF 50+), as well as the (super)hydrophilicity of TiO₂-modified PA fabrics, regarding the type of employed TiO₂ colloidal dispersion.
