标准FZ/T73023——2006应用于竹原纤维织物抗菌性的研究 总被引:4,自引:0,他引:4
采用最新标准对竹原纤维织物及毛竹竹粉的抑菌率进行了测定.在奎因法和振荡法中,竹原纤维织物对金黄色葡萄球菌(ATCC 6538)的抑菌率分别为50.1%和9.0%,时大肠杆菌(8099)的枊菌率分别为75.1%和26.5%,毛竹竹粉的抑菌率均为0.根据新标准评价竹原纤维织物虽有一定的抑茵性,但无抗菌效果,并且毛竹竹粉无抗菌效果.分析认为竹原纤堆自身不舍有抗菌化学物质,其抑菌性能来源于天然、独特的纤雏结构,属于物理抑菌. 相似文献

The technique of atmospheric pressure plasma is of value in textile industry. In this paper, argon (Ar) and argon/oxygen (Ar/O2) atmospheric pressure plasma were used to treat wool and ramie fibers. The structures and properties of treated fibers were investigated by means of SEM, XPS, single fiber tensile tester and so on.The results proved that the effects of plasma treatments depended on structural characteristics of fibers to a great extent, besides conditions of plasma treatment. By atmospheric pressure plasma treatment, wool fiber had significant changes in morphology structure, surface chemical component, mechanic properties and dyeability, while ramie fiber just showed a little change. In additional, Ar/Q2 plasma showed more effective action than argon. And at the beginning of treatment, plasma brought about remarkable effects, which did not increase with prolonging of treat time. 相似文献
