With tetraethylorthosilicate(TEOS) as precursor,sodium dodecyl benzene sulfonate(SDBS) as the emulsifier,hydrochloric acid as catalyst,SiO2 hydrosol was prepared.The functional sol was prepared by adding γ-methacryloxy propyl trimethoxyl silane(MPS) double bond coupling agent,dodecyl triethoxy silane(DTES) and light initiator 1173.After the cotton fabric was treated with the functional sol and cured with UV light,the fabric surface was superhydrophobic,and the contact angle reached 150°.When DTES was 8% and the light curing time was 40s,the contact angle of modified fabric surface was 150.63°,and the fabric surface was superhydrophobic.After soaping 10 times,the treated fabric surface still presented certain hydrophobic effect.The tensile breaking strength was improved,but the softness,gas permeability and water permeability were reduced.
