<p>The present invention is to provide a filter including polyvinylidene fluoride nanofibers and a meltblown non-woven fabric. A polyvinylidene fluoride nanofiber non-woven fabric layer is formed on a biocomponent substrate. Also, a polyethylene terephthalate substrate is formed on the other surface of the bicomponent substrate, and the meltblown non-woven fabric is formed on one surface of the polyvinylidene fluoride nanofiber non-woven fabric layer.</p> |
