This study aims to synthesis the self-cleaning fibers. The nano-titanium dioxide (TiO2) were blend with the polypropylene (grade 561R) at 1wt%, 3wt%, 5wt%, 10wt%, 15wt% and 20wt%. The TiO2-fibers were obtained from single screw extruder. The mechanical, thermal, rheology and self-cleaning properties were also investigated. The results showed that the tensile strength of the nTiO2-PP fibers decreased with increasing of the amount of TiO2. The presents of the TiO2 in the PP fibers significantly showed the improving of the self-cleaning properties under sunlight and 20 watt of UV radiation. The TiO2-PP fibers in presents of TiO2 20wt% showed the best results of self-cleaning under 5 hours of the sunlight which the similar results were found under 5 hours of 20 watts of UV radiation.
