The aim of this research was to obtain self-cleaning properties of PES surfaces by nano-modification with TiO2 coatings. The sol-gel process was used to prepare TiO2 nanoparticles and the influence of process conditions on the formation of nano-coatings was studied. Acid and alkaline catalysts were used in the polycondensation process of TiO2. The heat treatment of nanoparticles on the polyester substrate caused the formation of a polymorphic form of TiO2 anatase which has a wider band gap than the crystal structure rutile. To determine the efficiency of the fibre nano-modification and influence of the treatment on the fibre properties, the photocatalytic activity was observed by Foron Brill. Violett EBIN degradation and the mechanical properties were determined. The results show that the photocatalytic properties of TiO2 coatings obtained from acid sol are higher than those obtained from alkaline sol. However, the influence on mechanical properties of PES knitted fabrics was insignificant irrespective of the treatment conditions used in the process.
