The second part of the article presents the results of a study of antimicrobial activity of filter nonwovens with an addition of biocides, as a function of the presence of sweat in the environment and the method of microbe deposition on a nonwoven in the form of a liquid and a bioaerosol. At the same time, the filtration efficiency of nonwovens against microorganisms in the form of a bioaerosol was tested with the dynamic method. The results showed that the addition of sweat on the surface of a nonwoven resulted in an insignificant decrease of biological activity that still remained high. Moreover, an active nonwoven showed biostatic and biocidal activity only when microbes were deposited on the surface in the form of a solution. The nonwoven did not show any biological activity after deposition of microorganisms with the dynamical method in the form of a bioaerosol.
本文的第二部分介绍了添加杀生物剂的过滤无纺材料的抗菌活性研究结果，研究内容涉及环境中汗液的存在、微生物以液体和生物气溶胶形式沉积在无纺材料上的方式。同时，还采用动态法测试了无纺材料对生物气溶胶形式的微生物的过滤效率。结果表明，汗液在无纺材料表面的添加导致生物活性略有下降，但仍保持较高水平。此外，只有当微生物以溶液形式沉积在表面时，活性无纺材料才表现出抑菌和杀菌活性。而采用动力学方法以生物气溶胶形式沉积微生物后，无纺材料没有显示出任何生物活性。
