The invention relates to the filter for removing of physical and/or biological impurities from the filtrated media containing the textile fibres. The filter contains at least one couple (L) of nanofibrous layers, out of which in the direction of passage of the filtrated media the first nanofibrous layer is an active nanofibrous layer (2) formed of polymeric nanofibres containing particles of at least one low molecular substance active against the removed biological impurity or removed biological impurities, and the second nanofibrous layer is represented by the filtration nanofibrous layer (3) formed of polymeric nanofibres, while the size of gaps for passage of filtrated media between nanofibres of the filtration nanofibrous layer (3) is smaller than the size of gaps for passage of filtrated media between nanofibres of active nanofibrous layer (2) and smaller than the size of elements of biological impurity or biological impurities removed by means of this filtration nanofibrous layer (3). Next to this the invention relates to the air filter and water filter and to the face screen for protection against biological impurities.
La présente invention concerne un filtre d'élimination d'impuretés physiques et/ou biologiques du milieu filtré contenant les fibres textiles. Ce filtre contient au moins un couple (L) de couches nanofibreuses. La première couche, selon le sens de passage du milieu filtré, est une couche nanofibreuse active (2) dont les nanofibres polymères sont chargées de particules d'au moins une substance de faible masse moléculaire active contre les impuretés biologiques à éliminer. La seconde couche nanofibreuse, qui est celle de filtrage (3), est faite de nanofibres polymères. Les dimensions des orifices de passage du milieu filtré entre les nanofibres de la deuxième couche (3) sont inférieures à celle de la première couche (2), et inférieures aux dimensions des éléments d'impuretés biologiques éliminées par cette seconde couche (3). L'invention concerne également des filtres à air et des filtres à eau, ainsi que des masques de protection contre les impuretés biologiques.
