ELECTRET NANOFIBROUS WEB AS AIR FILTRATION MEDIA |
| 摘要 |
The present invention is directed toward an improved air filtration medium comprising a single layer polymeric nanofibrous web comprising a single source randomly intermingled fiber network with electrostatic charge up to −20 kV, a filtration efficiency range from about 70% to about 99.99%, and an air resistance less than about 2.5 mm wg for 0.3 diameter micron particles. The air filtration medium is made from a centrifugal melt spinning process. |
