摘要： An electrostaticly charged filtration media is provided including a plurality of polymeric structured polymeric film layers having a structured surface defined on at least one face of each structured film layer forming at least in part flow channels. The plurality of structured film layers are configured as a stack with the structured surfaces defining a plurality of ordered inlets open through a face of the stack that are in fluid communication with ordered fluid pathways. Each fluid pathway is defined at least in part by at least one discrete flow channel such that fluid can flow substantially unimpeded from one of the inlets to an outlet opening at another face of the stack. A layer of fluid pathways is defined by two opposing charged film layers at least one of which is a structured film layer. The flow channels have an average height of from 0.1 mm to 5 mm and an average width of from 0.05 mm to 50 mm and an average aspect ratio of from 0.5 to 10.

摘要： A filter element in the form of a nonwoven self-supporting filtration web having rows of folded or corrugated spaced-apart pleats, the web containing continuous thermoplastic fibers a majority of which are aligned at 90°±20° with respect to the row direction. The filter element can be made by forming rows of pleats in such a nonwoven web and cutting the web to a desired size and shape. The filter elements can provide improved mechanical and filtration properties and can exhibit reduced susceptibility to pleat deformation and the loss of space between pleats.

In other embodiments, the discrete fibers include a first population of monocomponent thermoplastic fibers having a first melting temperature, and a second population of monocomponent fibers having a second melting temperature greater than the first melting temperature. In certain embodiments, at least some of the particulates are bonded to the fibers. In other embodiments, at least some of the particulates are secured within interstices of the fibrous web, without substantial bonding to the fibers.
