Title (EN) ATMOSPHERIC PLASMA TREATMENT OF MELTBLOWN FIBERS USED IN FILTRATION
(FR) TRAITEMENT PLASMA ATMOSPHERIQUE DE FIBRES OBTENUES PAR FUSION-SOUFFLAGE UTILISE POUR LE FILTRAGE
Abstract: front page image
(EN)An improvement in filtration is seen by treating microfibers with a gaseous plasma at atmospheric conditions. The improvement results from etching the microfibers thereby increasing the surface area of the microfibers.
(FR)L'invention concerne une amélioration apportée au domaine du filtrage par traitement de microfibres avec un plasma gazeux dans des conditions atmosphériques. Cette amélioration résulte de la gravure des microfibres, ce qui permet d'améliorer leur surface.
