Title Aspects of tests and assessment of filtering materials used for respiratory protection against bioaerosols. Part I: Type of active substance, contact time, microorganism species; Part II: Sweat in the environment, microorganisms in the form of a bioaerosol
Bibliographic information 2010, Vol.16, No.2, p.263-273. Illus. 23 ref. (Part I); p.275-280. Illus. 5 ref. (Part II)
Abstract 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 are presented in two articles. The first article examines how the type of active agent, the duration of the contact of microorganisms and the type of microorganisms affect the activity of nonwovens. The second article investigates whether an addition of artificial sweat to a bioactive nonwoven has a protective effect on the microbes and whether it changes their survivability. In addition, the sensitivity of bacteria deposited on a nonwoven in the form of a liquid and a bioaerosol was tested. The filtration efficiency of nonwovens against microorganisms in the form of a bioaerosol was also tested with a dynamic method. Findings are discussed.
