The present invention relates to a multi-layered nanofiber filter medium and a method for manufacturing same, in which, to improve the low heat resistance of existing filters, nanofibers are layered by continuously electro-blowing and electrospinning heat resistant polymer on a cellulose substrate. Additionally, the present invention relates to a multi-layered nanofiber filter medium and a method for manufacturing same, in which nanofibers are layered by continuously melt-blowing and electrospinning heat resistant polymer on a cellulose substrate. |
