Abstract

Poly(ethylene phthalate) (PET)/nano‐TiO~2~ composites prepared via in situ polymerization were spun into fiber by the melt‐spinning process. The dispersion of nanosized rutile TiO~2~ in the PET was studied using transmission electron microscopy (TEM) and scanning probe microscopy (SPM) techniques. The mechanical properties and the properties of ultraviolet (UV) protection were investigated. The results showed that rutile TiO~2~ can be dispersed uniformly by the in situ polycondensation process. The mechanical properties of PET/TiO~2~ fiber were slightly affected by adding nano‐TiO~2~. The UV‐ray transmittance of PET/nano‐TiO~2~ fabrics was below 10% in the UV‐A band and below 1% in the UV‐B band. And the ultraviolet protection factor (UPF) of PET/nano‐TiO~2~ fabrics was greater than 50. All these PET/TiO~2~ nanocomposite fabrics exhibited excellent UV‐blocking properties. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 100: 1588–1593, 2006
