摘要:国内外对纺织品抗菌性能的评价各不相同,对不同类别的纺织品也没有公认和统一的测试标准,因此采用恰当的实验方法对镁基抗菌织物进行测试,能够保证测试结果的准确性。采用改良AATCC100法和改良振荡法对镁基抗菌织物的大肠杆菌和金黄色葡萄球菌抗菌性能进行测试。结果表明:镁基抗菌织物对大肠杆菌和金黄色葡萄球菌的抑菌率均在90%以上,且两种方法所得结果接近、结论相同。镁基抗菌织物对大腸杆菌和金黄色葡萄球菌具有良好的抑菌效果。

There are no recognized and unified testing standards for different textiles. In order to ensure the accuracy of test results, appropriate test methods should be chosen to test magnesiumbased antibacterial fabric. Improved AATCC100 and improved oscillation method were applied to test antibacterium capability of magnesiumbased antibacterial fabrics for E.coli and Staphylococcus aureus. The results show that the bacteriostatic rate of the magnesiumbased antibacterial fabrics for the two kinds of bacteria is above 90%. And the results and conclusions gained by both methods are similar. The magnesiumbased antibacterial fabrics have obvious antibacterial effect on E.coli and Staphylococcus aureus.
Key words:magnesiumbased antibacterial fabrics; test criteria; improved AATCC100; improved oscillation method; bacteriostatic rate

近几年国内外市场研制并生产了大量的抗菌织物产品,然而产品质量良莠不齐,因此如何正确的检测并评价出这些产品的抗菌性能,促进功能性纺织品市场良好的发展和保障消费者权益就显得尤为重要。……
