Abstract Cotton fabric was finished in a simple one-step process to prepare superhydrophobic cotton fabric. Cetyltrimethoxysilane (HDTMS) was adop-ted to reduce surface energy of cotton fabric due to its long alkane chain, the nano-silica particles (SNP) were used to improve the surface roughness of the fabric. The ethylene diamine tetraacetic acid (EDTA) was applied to improve the treatment durability. The effects of SNP, EDTA and HDTMS concentration on the hydrophobicity of finished cotton fabric were studied. The results showed that the optimized conditions could be obtained when the concentration of SNP, EDTA and HDTMS were 1.0wt%, 1.0wt% and 4.0wt%, separately. The superhydrophobic cotton fabrics exhibited superhydrophobicity with an average water contact angle of 160.5°, and oleophobicity with an average oil contact angle of 155.5°. Furthermore, the durability efficiency of samples was quantitatively evaluated using standard washing test and the result showed the enhancement of EDTA.

Key words： superhydrophobicity silica nanoparticles ethylenediaminetetraacetic acid hexadecyltrimethoxysilane cotton
