Abstract
L'invention concerne un milieu filtrant sous forme de nappe comportant des fibres à deux composants non frisées liées par voie autogène, qui contiennent une polyoléfine et un autre polymère thermoplastique possédant des points de fusion différents. Ce milieu filtrant présente une masse volumique comprise entre environ 0,07 g/cm<3> et environ 0,2 g/cm<3>. L'invention se rapporte également à un milieu filtrant thermoformé en trois dimensions, qui présente une masse volumique comprise entre environ 0,07 g/cm<3> et environ 0,5 g/cm<3>.
