This paper presents the results of a study on antimicrobial activity of polymer filter nonwovens produced by needle-punching or melt-blowing with an addition of disinfecting agents. The first part of the paper discusses how the biocidal activity of nonwovens is a function of the active agent added to the nonwovens, the duration of the contact of microorganisms with nonwovens and the type of microorganisms. The types of fibres and disinfecting agents had a considerable effect on the biocidal activity of nonwovens. The biocidal effect of nonwovens increased with the duration of their contact with microorganisms. Fibre activity differed considerably depending on the species of the microorganism. The microorganisms most sensitive to biocidal activity of the active filter nonwoven were S. aureus, M. flavus and E. coli. There were no biocidal effects on spore-forming bacterium B. subtilis.
本文介绍了通过针刺或熔喷工艺生产的添加了消毒剂的聚合物过滤非织造布的抗菌活性研究结果。本文的第一部分讨论了非织造布的杀菌活性如何取决于添加到非织造布中的活性剂、微生物与非织造布接触的持续时间以及微生物的类型。纤维和消毒剂的类型对非织造布的杀菌活性有很大的影响。非织造布的杀菌效果随着与微生物接触时间的延长而增加。纤维的活性因微生物的种类而异。对活性过滤非织造布的杀菌活性最敏感的微生物是金黄色葡萄球菌、黄曲霉和大肠杆菌。对芽孢形成菌枯草芽孢杆菌没有杀菌作用。
