MULTI-LAYERED NANOFIBER FILTER MEDIUM USING ELECTRO-BLOWING, MELT-BLOWING OR ELECTROSPINNING, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention, aimed to enhance low heat-resistant ability of the current filters, relates to multi-layered nanofiber filter media and its manufacturing method, laminating nanofiber using electro-blown and electro-spinning subsequently on a cellulose substrate. In addition, the present invention relates to multi-layered nanofiber filter media and its manufacturing method, laminating nanofiber using melt-blown and electro-spinning subsequently on a cellulose substrate.
