NANOFIBER FILTER USING ELECTRO-SPINNING AND MELTBLOWN AND ITS MANUFACTURING METHOD

摘要

The present invention relates to a heat resistant multilayer film having nanofiber laminated by continuously using melt-blowing and electro-spinning of a heat resistant polymer on a cellulose base material for improving low heat resistance of an existing filter. The manufactured heat resistant multilayer filter includes multilayer of heat resistant filter to be characterized by having not only excellent heat resistance but also excellent filter efficiency.
