Textiles, with appropriate light absorbers and suitable finishing methods, can be used as ultraviolet (UV) protection materials. In this study, we investigated the effects of nano‐TiO 2 particles on the UV‐protective and structural properties of polypropylene (PP) textile filaments. Master batches of PP/TiO 2 nanoparticles were prepared by melt compounding before spinning, and filaments incorporating 0.3, 1, and 3% TiO 2 nanoparticles were spun in a pilot melt‐spinning machine. The structural properties of the nanocomposite fibers were analyzed with scanning electron microscopy, X‐ray diffractometry, differential scanning calorimetry, and tensile tests. The UV‐protection factor was determined to evaluate the UV‐protective properties of the filaments. In conclusion, although the structure and mechanical properties of the nanocomposite filaments were slightly affected by the addition of nano‐TiO 2 , the UV‐protective properties of the PP filaments improved after treatment with nano‐TiO 2 , and the nanocomposite filaments exhibited excellent UV protection. © 2009 Wiley Periodicals, Inc.
