摘　　要：探讨纤维素酶及无氟化合物处理棉织物的润湿性。利用纤维素酶与棉织物的温和水解反应,在纤维表面刻蚀形成粗糙结构,再通过引入长链硅氧烷分子降低表面能得到超疏水棉织物,探究了低表面能处理条件对超疏水效果的影响。试验表明:引入的硅氧烷分子侧链越长则表面能越低,硅氧烷体积分数控制在5%时试验体系可最优化降低其表面能,认为通过此法制备的超疏水棉织物具有良好的长效疏水稳定性。Wettability of cotton fabric modified by cellulase and fluorine-free compound was discussed.Mild hydrolysis reaction of cellulase and cotton fabric was used to etch the fiber for a rough structure,then superhydrophobic cotton fabric was obtained by introducing long-chain siloxane molecules to reduce the surface energy.The influence of low surface energy treatment conditions on the super hydrophobic effect was explored.Experiments showed that the longer the side chain of the silane molecule was,the lower the surface energy was.When the volume concentration of silane was controlled at 5%,the experimental system could be optimized to reduce its surface energy.It is considered that the superhydrophobic cotton fabric prepared by this method has better long-term hydrophobic stability.
