The filter materials commonly used in micro-filtration processes consist of nonwoven fabrics made by melt-blowing. In order to improve the filterability of nonwovens, they are subjected to various modifications. This paper proposes the treatment of nonwovens with Iow-pressure cold plasma (LPCP) using process gases such as air, methane and hexamethyldisiloxane (HMDSO). The effectiveness of this treatment was assessed on the basis of the results of the penetration of nonwovens by NaCl aero-dispersion in a flux of air and flow resistance data. The effects of plasma on filter nonwovens, especially on their chemical structure and surface topography were evaluated by means of ATR-IR spectroscopy and SEM microscopy. The nonwoven filters obtained show a high effectiveness of filtration and do not increase the resistance of air flow.

W procesach mikrofiltracji stosowane są powszechnie włókniny melt-blowing. W dążeniu do podniesienia skuteczności filtracyjnej włókniny poddawane są różnorodnym modyfikacjom. W pracy proponowana jest obróbka włóknin w plazmie RF z wykorzystaniem gazów procesowych: powietrza, metanu, HMDSO. Skuteczność zastosowanej obróbki oceniano na podstawie wyników penetracji i oporów przepływu aerozolu NaCl w strumieniu powietrza. Oceniano także efekty wywoływane oddziaływaniem plazmy na włókniny filtracyjne w zakresie wpływu na budowę chemiczną i topografię powierzchni przy użyciu techniki spektroskopii absorpcyjnej promieniowania ATR-IR i mikroskopii SEM. Otrzymano filtry o wysokiej skuteczności filtracji, które nie zwiększają oporów przepływu aerozolu.
