APPARATUS AND METHOD FOR MANUFACTURING ELECTRET MEDIA

摘要

Provided is an apparatus for producing electret media. The apparatus for producing the electret media includes: a supply container storing a polar solvent; a discharging part coupled to the supply container so as to discharge the polar solvent; and a moving part moving the media relatively with respect to the discharging part so that the media can be charged as the polar solvent discharged from the discharging part passes through. The discharging part discharges, onto the media, the polar solvent in a uniform amount along a width direction of the media.
