Car covers have continuous development in recent years. It is one of the most important car accessories that can help maintain the car's appearance, and are considered one of the necessary things due to their effective role in protecting the car from all climatic fluctuations that negatively affect the car's appearance (dust and dirt, acid rain, ultraviolet sunlight). Therefore, this research aims to achieve the best functional properties of the car cover, so that it has the following properties (high tensile strength - lightweight - resistance to dirt). To achieve this goal, nine woven samples were produced with different variables (textile structure and weft density per units of measurement) and treated with nano titanium dioxide) TiO2(and Honey bee propolis. It was evaluated by conducting various tests on it to determine the best functional properties, our results showed the extent of the effect of the density of the weft in cm on the fabrics, becomes clear, as the higher the density of the weft threads in cm, the higher the rate of saturation of the material with the treated substance, which increases its effectiveness, and thus increases the fabric's resistance to water and increases its self-cleaning rate. The length of the fabric float in weave structure is considered one of the most important elements that directly affects the fabric's resistance to water and increases its self-cleaning rate. The best sample performance evaluated by radar chart is sample (S12) manufactured with cotton in warp and Microfiber polyester in weft material for 40 wefts with double weave structure (Face: matt rib 2/2 Back: matt rib 2/2).
