HEPA(H-10) PERFORMANCE SYNTHETIC NONWOVEN AND NONOFIBER COMPOSITE FILTER MEDIA

摘要

PURPOSE: The present invention crinkles to corrugated or the composite non-woven filter medium which is embossed. The efficiency of filtration excellent. Provided is the composite filter medium structure. CONSTITUTION: A composite filter medium structure comprises the base material(72) which includes the nonwoven fabric material formed from a plurality of binary synthetic fibers by using the spun bond process. The nano fiber layer sunk with the electro-blown spinning process on one side of the base material is included. At this time, according to the ASHRAE 52.2-1999 testing method, the base material and nano fiber layer offer the efficiency of filtration more than 85% in measurement.
