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.
