The Effect of Combination Electrospun and Meltblown Filtration Materials on Their Filtration Efficiency

摘要

Filtration materials prepared by combination of electrospun nanofibers and meltblown microfibers (both fixed on polypropylene spunbond supports) were characterized from the point of view of their filtration efficiency in ultrafine particles separation. Compared are electrospun and meltblown structures and their combinations characterized by means of digital image analysis properly. Layer of electrospun nanofibers in MB air filtration materials can ensure improvement of filtration efficiencies for ultrafine particles separation.
