Woven Military Fabrics from the Aspect of the Microbial Barrier Permeability

Functionality is of utmost importance for fabrics designed for military purposes, where woven fabric structural parameters and finishing processes greatly affect the definition and achievement of high set properties demands. Considering the application conditions of military fabrics and the high exposure to microorganisms from environment, as well as from the direct and indirect transfer between users, the possibility of contamination is unavoidable. Therefore, the aim of this paper is to determine whether and to what extent military fabrics have the properties of microbial barrier permeability. Determination of microbial barrier permeability was conducted according to the newly developed method. The most resistant forms of microorganisms were used, the bacterial endospores of apatogenic species: Geobacillus stearothermophilus and Bacillus atrophaeus. The analysis of the obtained results and the analysis of correlations between some relevant fabric properties confirm the extremely complex structural aspect of the woven fabrics. Tested woven fabrics designed for military purposes show a very good microbial barrier permeability with a different adhesion of microorganisms, conditioned by the complex woven fabric structure, based on which can be approached to further targeted functional designing of specific elements.
