为制备具有耐洗涤性能的抗菌棉织物，利用环氧基团与棉织物的羟基形成共价键，通过自由基聚合法制备了有机-无机P（DMDAAC-AGE）/Ag/ZnO复合抗菌棉织物。采用XRD、FT-IR、TEM等测试手段对P（DMDAAC-AGE）/Ag/ZnO复合材料的表面形貌、晶相和化学结构进行了表征。所得P（DMDAAC-AGE）/Ag/ZnO复合功能化棉织物具有优异的抗菌活性和耐洗性。在抗菌测试中，抑菌减少率大于99.75%，并且即使在11次洗涤循环（相当于55次商业或家庭洗涤循环）后仍保持在99.00%以上。对抗菌机理进行了初步探讨，包括离子释放和抗菌作用。该整理剂在保持棉织物基本性能的同时，还具有优异的防霉性能。这些结果表明，改性棉织物在运动服装、袜子和医用纺织品等领域有潜在的应用前景。
To prepare antibacterial cotton fabrics with laundering durability, an organic-inorganic P(DMDAAC-AGE)/Ag/ZnO composite was synthesized by free radical polymerization where the epoxy groups were utilized to form covalent bonds with the hydroxyl groups of cotton fabrics. The surface morphology, crystal phase and chemical structure of the obtained P(DMDAAC-AGE)/Ag/ZnO composite were characterized by XRD, FT-IR and TEM measurements. The resulting P(DMDAAC-AGE)/Ag/ZnO composite-functionalized cotton fabrics exhibited outstanding antibacterial activity and excellent laundering durability. In the antibacterial tests, the bacteriostatic reduction rate was greater than 99.75%, and remained over 99.00% even after 11 washing cycles (equivalent to 55 commercial or domestic laundering cycles). The antibacterial mechanism was also investigated, partly including release of ions and photocatalysis. Moreover, the coated cotton fabric possessed excellent anti-mildew performance and also maintained the basic properties of cotton fabric. These results suggest that the modified cotton fabrics may find potential applications in a wide variety of areas such as sportswears, socks, and medical textiles.
