摘　　要：为提高棉织物的抗菌性能,将聚乙烯醇与壳聚糖溶液共混,以戊二醛为交联剂,制备抗菌水凝胶预聚液,通过浸渍整理制备了水凝胶复合织物。采用扫描电子显微镜、傅里叶红外光谱仪、热失重分析仪、万能材料拉力机等对整理前后棉织物进行测试与表征。结果表明:聚乙烯醇/壳聚糖水凝胶在棉织物表面形成一层均匀的水凝胶膜;改性棉织物的断裂强度和断裂伸长率略有提高,热稳定性降低,抗菌性能显著提高,对大肠埃希菌和金黄葡萄球菌的抑菌率高达99.9%。In order to improve the antibacterial property of cotton fabric,the hydrogel composite fabric is pre⁃pared by blending polyvinyl alcohol with chitosan solution and using glutaraldehyde as a crosslinking agent.Scanning electron microscopy,Fourier transform infrared spectroscopy,thermogravimetric analyzer and univer⁃sal material tensile machine are used to analyze cotton fabrics before and after finishing.The results show that PVA/chitosan hydrogel forms a uniform hydrogel film on the surface of cotton fabric.The breaking strength and elongation of modified cotton fabric are slightly increased,thermal stability is decreased,and antibacterial prop⁃erty is significantly improved with 99.9%of antibacterial rate against Escherichia coli and Staphylococcus aure⁃us.
