中文摘要:
      采用乳液聚合法合成了含氟丙烯酸酯乳液(FP),并结合溶胶凝胶法制得的SiO2,通过浸渍-固化法涂覆到棉织物上,成功制备了具有超疏水性能的棉织物。利用红外光谱、扫描电镜、原子力显微镜、粒度分析、差示扫描量热分析、热重分析及接触角(CA)等测试手段研究了高聚物的结构形貌和热稳定性,讨论了摩擦及皂洗对织物疏水性的影响,随后考察了织物在整理前后的防紫外性能、白度、透气性、折皱回复角及断裂强力等性能的变化。结果表明,FP及SiO2/FP整理后的棉织物均具备超疏水能力,且SiO2/FP整理织物(CA=157°)比FP整理织物(CA=153°)的疏水性好,说明硅溶胶先对棉纤维表面进行粗糙化处理再附载FP提高了其疏水性。经多次水洗或摩擦后织物仍能保持较好的疏水效果,而且整理前后棉织物物理力学性能变化不大,不会影响棉织物的服用性能。
英文摘要:
      The fluorine-containing acrylate emulsion (FP) was synthesized by emulsion polymerization method, and SiO2 was prepared by sol-gel method. They were coated on cotton fabrics by impregnation-curing method, and cotton fabrics with superhydrophobic properties were successfully prepared. Subsequently, the structure and morphology of the polymer and thermal stability were studied by FT-IR, SEM, AFM, particle size analyzer, DSC, TG and contact angle tester. The effects of friction and soaping on the hydrophobicity of the fabric were discussed. In addition, some property changes of the fabric before and after finishing were investigated including the anti-ultraviolet performance, whiteness, permeability, wrinkle recovery angle and breaking strength. The results show that the cotton fabrics treated by FP or SiO2/FP have superhydrophobic ability, and the moisture resistance of the SiO2/FP finishing fabric (CA=157°) is better than that of the FP finishing fabric (CA=153°), indicating that the surface of cotton fiber is roughened with silica sol and then coated with the FP to improve the cotton fabric hydrophobicity. After repeated washing or friction, the fabric still maintains a good water repellent effect. The physical and mechanical properties of cotton fabrics hardly change before and after finishing, which has no influences on the clothing performances of cotton fabrics.
