A variety of microporous liners containing microfibers and nanofibers have been combined with cotton-based fabrics in order to filter aerosolized particles for protective garment applications. In our recent studies, we have measured the effect of these nanofiber-containing liners on the aerosol penetration resistance of the lined fabrics and we have measured where the particles are captured within the fabric layers. Testing has been conducted with aerosolized spores, in order to evaluate the efficacy of various fabric treatments on spore viability within the fabric layers after exposure. In this presentation, we will report on the results of our studies on fabrics with and without a removable electrospun nanofiber liner, and the fate of the spores within the fabric layers.
