<p>A web, formed from dielectric fibers and non-dielectric fibers, which has been subjected to corona discharge to improve the particulate filtration properties of the web is provided. The dielectric and non-dielectric fibers may be intermingled within the web such that the distribution of the dielectric and non-dielectric fibers within the web is generally uniform. In one embodiment, the dielectric fibers may be formed from a thermoplastic polymer, and particularly polyolefin and the non-dielectric fibers may be formed from cellulose, and particularly wood pulp.</p> |
