摘要: Fluid filtration articles, including composite nonwoven fibrous webs, and methods of making and using such articles as gas or liquid filtration elements. The articles include a population of coarse microfibers having a population median diameter of at least 1 micrometer (μm) formed as a first layer, and a population of fine fibers having a population median diameter less than 10 μm formed as a second layer adjoining the first layer. At least one of the fiber populations may be oriented. In one implementation, the coarse microfibers and fine fibers are polymeric, the coarse microfibers have a population median diameter of at least 10 μm, and the fine fibers have a population median diameter less than 10 μm. In another implementation, the population of fine fibers has a population median diameter less than 1 μm. Optionally, one or both of the first and second layers may include particulates.

摘要: A method of forming a filter element is disclosed comprising introducing a mixture into a mold, the mixture comprising a plurality of susceptor particles and a plurality of polymeric binder particles. Eddy currents are induced in the susceptor particles by subjecting the mixture to a high-frequency electromagnetic field, the eddy currents being sufficient to elevate the temperature of the susceptor particles to cause adjacent polymeric binder particles to be heated to at least a softening point. The susceptor particles bind with the heated polymeric binder particles in the mold to form a coherent mass. The coherent mass is cooled to form the filter element.
