Superhydrophobic finishing of cotton fabric based on cellulose derivatives
In order to endow cotton fabrics with superhydrophobic properties,the synergistic effect of cel-lulose acetylacetate film forming agent with octadecylamine,3-aminopropyltriethoxysilane,and nano silica on the hydrophobic properties of cotton fabrics was studied.The results showed that when the rolling rate of cel-lulose acetoacetate aqueous solution was 80%,the rolling rate of hydrophobic finishing agent was 70%,among them,the dosage of octadecylamine was 7%,the dosage of 3-aminopropyltriethoxysilane was 1%,and the dosage of nano silica AEROSIL®R812 was 1.5%,the dosage of nano silica AEROSIL®R8200 was 0.5%,the pre-drying temperature was 80℃,and the baking temperature was 120℃,the static contact angle of treated cot-ton could reach up to 154°,while its sliding angle could be low to 10° illustrating the treated cotton was super-hydrophobic.
