<p>The present invention relates to a multilayered nanofiber filter with improved heat resistance on substrates, which is manufactured by stacking multilayered nanofibers with improved heat resistance on the substrate with use of an electricity spinning method to resolve low heat stability of a conventional nanofiber filter. In the present invention, the multilayered nanofiber filter on substrates is manufactured by stacking meta-aramid nanofibers on a meta-aramid substrate and electrically spinning polyimide nanofiber continuously on the meta-aramid nanofibers, thereby leading to a functional filter with the efficiency of the filter, a competitive price, high efficiency and heat resistance.</p> |
