In this paper, we reported the synthesis of TiO 2 /γ-(methacryloyloxy)propyltrimethoxysilane (KH570) hybrid nanoparticles with simple and mild condition at room temperature. The as-prepared TiO 2 /KH570 hybrid nanoparticles were characterized by FT-IR, XRD, SEM, EDS, and XPS. The hybrid nanoparticles were coated onto the surfaces of polyethylene terephthalate (PET) fabrics by pad-dry-cure (PDC) process. The morphology, structural, and chemical composition of the coated fabrics were analyzed by SEM, EDS, and XPS. The ultraviolet protection factor (UPF) was used to evaluate the UV protection property of PET fabrics. The coated PET fabric exhibited good UV resistance abilities with a UPF value of 50+. The air permeability of the coated PET fabrics decreased significantly compared with the original PET fabrics. The coated PET fabrics also showed good washing stability. The coated fabrics had an excellent protective effect against ultraviolet rays after exposure to ultraviolet light for a period of time. The PDC process only caused a small degree loss of the tensile strength of the coated PET fabrics.
