Nanograde titanium dioxide (TiO2) and Zinc oxide (ZnO) are the photo-semiconductor most discussed in the relevant literature. The present studies report on the results from the antiageing effects and fading degrees of dyed Nylon fabrics, using aqueous suspensions of Nanograde titanium dioxide and zinc oxide under UV light as a function of irradiation time at a variety of conditions .The photo-degradation kinetics, thermal properties (Tg、Tm), dyeing fastness and physical properties were studied under different conditions such as nanograde particles concentration and types, the irradiation time of UV light. It was found that the photo-degradation rates and fading degrees decreasing with nanograde particle concentration. Another, The dyed Nylon fabrics after finishing still remain to be good strength and softness. The Nanograde particle ZnO was found to be more efficient compared with TiO2, and both ZnO and TiO2 had the outstanding anti-ageing properties for dyed Nylon fabrics.
