摘　　要：以正硅酸四乙酯(TEOS)为硅源,γ-氨基丙基三甲氧基硅烷(APTMS)为改性剂,制备氨基改性纳米二氧化硅(A-Si O2)溶胶,利用红外光谱仪对其进行表征,并用于棉织物整理。处理后的棉织物再浸轧低表面能聚二甲基硅氧烷(PDMS),测试其超疏水性。结果表明,处理后的棉织物与水的接触角为153.35°,滚动角为9°;经柠檬酸预处理的棉织物,其耐洗性较好,20次皂洗后与水的接触角仍可达138.25°,滚动角为20°。A novel amino-modified nano SiO2 sol（A-SiO2） is prepared via sol-gel method using tetraeth- oxysilane （TEOS） and γ-amino propyl trimethoxysilane （APTMS） as raw materials, and then is applied to superhydrophobic finishing of cotton fabrics. The chemical structure of A-SiO2 is investigated by FTIR. The treated cotton fabrics are then coated with polydimethylsiloxane （PDMS）. The superhydrophobic performance of treated cotton fabric is analyzed. The results indicate that, contact angle and rolling angle of the treated cotton fabric are 153.35° and 9° respectively. Cotton fabric pretreated with citric acid has good washing fastness. The contact angle and rolling angle of treated fabric are 138.25° and 20° respectively after 20 washing cycles.
