    Abstract

    Electrospinning was used to produce lightweight coatings of polyamide-66 nanofibers on different fibrous substrates. Filtration efficiency of coated and uncoated samples and strain capacity of the nanofiber layer were tested. Filtration efficiency clearly increased even with the lowest amount of nanofibers (0.02 g/m2) when compared to uncoated samples, and with the highest nanofiber coating weight (0.5 g/m2) the filtration efficiency of submicron aerosol particles was over 90%. Elongation capacity of the polyamide nanofiber layer was found to be insufficient to be used with elastic materials. The polyamide nanofiber layer is, therefore, suitable to be used with relatively rigid substrate e.g. spunbond nonwoven and at least thicker nanofiber layers are advisable to be protected with cover layer, because the nanofiber layer also delaminates easily from the textile surface.
