| 摘要 |
<p>A method for the manufacture of an electrically charged fibrous filter from a highly molecular non-polar fiber material wherein a film of the fiber material is continuously fed and stretched. At least one side of the stretched film is homopolarly charged by a plurality of corona charging elements. The charged film material is then fibrillated, collected and processed into a filter.</p> |
