Durability of Multifunctional Shade Textile Materials modified by TiO2 Nanoparticles

The efficiency of the untreated and TiO2 modified four gray cotton woven fabric samples and three white polyester samples, with different construction characteristics, before and after natural weathering were evaluated by measuring UV permeability trough the shade materials, tensile strength, water-repellency, oil- repellency and fabrics appearance by colour change assessment. The analysis of breaking force of the examined fabrics shows by cotton fibres no significant changes after weathering, and by polyester fabrics that TiO2 used partially decreasing the fibres photo-degradation. The results obtained indicate considerable increasing of brightness and UV protective properties of all undyed fabric samples modified with TiO2 nanoparticles and excellent fastness to weathering as well. All cotton fabrics treated with TiO2 incorporated in fluorocarbon finish have got an excellent water- and oil- repellency, which is slightly reduced after weathering.
