摘要
抗菌加工已广泛用于提高纺织品的性能和卫生条件。本研究以壳聚糖（ＣＳ）为抗菌成份，采用戊二醛（ＧＡ）为交联剂，对棉织物进行抗菌处理，并对加工后织物的抗菌性、耐水洗性及强力、透气、透湿性能进行测试。结果表明：壳聚糖整理的棉织物对大肠杆菌、金黄色葡萄球菌、白色念珠菌的抗菌率为１００％，对枯草杆菌的抗菌率大于７５％，皂洗５０次后抗菌率为７５％；经处理后的织物具有良好的透气、透湿、吸湿和抗弯刚度。
Antibacterial antifungal finishing is widely carried out for improving textile properties and sanitary conditions especially preventing bacteria or fungus's infection mold from ravaging textiles.Cotton cloth is finished by cross-linking of chitosan (CS) as antibacterial affective components with glutaraldehyde (GA).Moreover, the antibacterial activity, wash fastness,strength, air permeability, water vapor permeability and stiffness of finished fabrics arc tested. The result is achieved that antibacterial index of fabric finished by chitosan is almost 100% to Escherichia coli, Staphylococcus aureus, Candida albicans. It concludes that the chitosan finished fabrics has excellent antibacterial activity, better water adsorption isotherm,pervousness and bending rigidity.
