Highly dispersed silica nanoparticles used for fabric coating were synthesized via nonsurfactant template sol–gel reaction with tetraethoxysilane (TEOS) and γ-glycidyloxypropyltrimethoxysilane (GPTMS) in the presence of dodecanol, alkaline catalyzer, and ethanol. With the optimum conditions of 4 g of dodecanol, 3 mL of alkaline catalyzer, and 30 wt% GPTMS, the silica particle size was 305 nm and the polydispersity index was 0.022. FT-IR spectra confirmed that the alkyl chain and epoxy group of GPTMS had been bonded onto the surface of silica nanoparticles due to the characteristic peaks at 2980 and 910 cm−1. The GPTMS-modified silica nanoparticles presented higher dispersion compared with the unmodified particles from SEM micrographs. The anti-ultraviolet property and rubbing fastness of the coated fabrics were enhanced as the doped amount of modified silica nanoparticles were increased to 5 wt%. The nonsurfactant template sol–gel method presents simple, facile, and cost-effective potential on the promising application of preparing highly dispersed silica nanoparticles.
