摘　　要：采用新的方法制备超疏水棉织物,突破了传统使用额外纳米粒子构造粗糙表面结构制备超疏水纺织品的局限性。首先采用有机硅树脂在织物表面形成一层疏水性薄膜,然后借助硅树脂的黏附性将十八胺牢固地固着在织物表面,以此达到构造粗糙表面结构和降低织物表面能的目的。实验结果表明,整理后的棉织物与水的接触角高达154.4°±0.6°,经、纬向强力分别下降了6.2%和8.3%,而白度增加了1.3%。棉织物表面经过30次机械摩擦后,其接触角为151.5°±0.4°。最后对改性前后棉织物的表面形貌和超疏水机理进行了深入分析。The superhydrophobic cotton fabric was successfully obtained by a novel strategy,for which the limitation of what the additional nanoparticles were used frequently to construct hierarchical rough surface for fabricating superhydrophobic textiles was broken.Firstly,a hydrophobic film was formed on the cotton fabric surface by using the resin,and then the octadecylamine was firmly fixed on fabric surface based on the adhesion property of silicone resin.Therefore,the purpose of constructing a rough surface structure and reducing the fabric surface energy was achieved.The experimental results show that the contact angle of the modified cotton fabric with water is as high as 154.4°±0.6°.In addition,the warp and weft strength are decreased by 6.2%and 8.3%,respectively.However,the whiteness is increased by 1.3%.The contact angle still reaches 151.5°±0.4°after 30 times of mechanical friction.Finally,the surface morphology and superhydrophobic mechanism of cotton fabric before and after modification were discussed in depth.
