The polyester with nanometer Ag-TiO2 has excellent antibacterial. In the experiment, it use two composite nanometer antibacterial to change nanometer Ag-TiO2 proportion and consistency. Then the finishing of polyester with different proportion oil & water repellent. The study on the effect of antibacterial and finishing efficient staphylococcus after the finishing textile of oil & water repellent. As a result, the polyester with nanometer Ag-TiO2 and oil & water repellent is that the antibacterial has decline while the proportion of oil & water repellent increase and the consistency of nanometer Ag-TiO2 and UV light grow up while antibacterial will rise.
