摘要： A self-support electrostatic filter has a filter media made of charged filter media with a first surface and a second surface, and two non-woven scrim layers made of welded long fibers. The non-woven scrim layers are ultrasonically bounded with the surfaces of the self-support electrostatic filter to form a triple layered filter media with supporting surfaces. Thus the triple layered filter media can be wavy folded for self-support without adhering to a piece of expanded metal mesh.

摘要： Filter media are provided having improved conductivity to enhance filtration efficiency and/or dissipate static charge, and methods for making the same. In one exemplary embodiment, the filter media can include a filtration substrate, and at least one conductive coating disposed on at least a portion of the filtration substrate. In use, the conductive coating is coupled to an energy source and it is effective to emit ions when energy is delivered thereto to increase the efficiency of the filtration substrate and/or to dissipate or eliminate static charge generated during filtration.

摘要： Fluid treatment elements substantially inhibit electrical charge imbalances and/or build-ups of electrical charges. A fluid treatment element may comprise a multilayer composite including an electrically conductive fibrous matrix, having an upstream side and a downstream side, disposed on a porous substrate, also having an upstream side and a downstream side, which supports the fibrous matrix. The fibrous matrix may include a combination of conductive and nonconductive fibers. The multilayer composite may also include a drainage layer positioned along one of the upstream side of the fibrous matrix and the downstream side of the porous substrate.

摘要： The present invention relates to a multilayer protective enclosure for protecting humans, animals or perishables from hazardous agents in the environment. The enclosure contains a porous adaptive membrane structure that has movable membranes with insertable protrusions. The structure can be made to change its gas, liquid or particulate permeability in response to surrounding environmental conditions. Hence, the enclosure is highly breathable in a non-hazardous environment but impermeable or only semipermeable in a hazardous environment.

摘要： The present invention provides a fiber with iodinated resin particles embedded therein. The innovative fibers a show no or negligible leaching of iodine into the atmosphere and thus are not toxic. In one aspect, the antimicrobial fibers can be bonded or woven together to form a filter media. Examples of nonwoven filters are provided. Additionally, an electric charge can be applied across the nonwoven substrate to increase antimicrobial efficacy.
