    摘要: A method of removing nano-sized pathogens from a liquid that includes providing a filter and contacting the filter with a liquid to remove nano-sized pathogens from the liquid. The filter includes a housing and a filter core disposed within the housing. The filter core comprises activated carbon particles, excluding sodium hydroxide treated activated carbon particles, wherein the activated carbon particles have an interparticle spacing wherein the filter has a Pathogen Removal Index (PRI) of at least about 99.99%.

    摘要: A fluid permeable structured fibrous web having thermally stable, fibers that are thermally bonded together using heat provides a base substrate that is thermally stable. The base substrate is textured via mechanical treatment producing a structured fibrous web having an aged caliper of less than 1.5 mm, a vertical wicking height of at least 5 mm, a permeability of at least 10,000 cm2/(Pa·s) and a specific volume of at least 5 cm3/g. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications. The structured fibrous web has a bio-based content of about 10% to about 100% using ASTM D6866-10, method B.
