    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.

    摘要: A filter block may comprise activated carbon filter particles without metallic biocides. The activated carbon filter particles may have a median particle size of less than or equal to about 90 microns and having a particle span of less than or equal to about 1.7. The filter block may have a permeability of greater than about 3.0×10−9 cm2 and a Filter Viruses Log Removal of greater than about 2 logs. A portion of the activated carbon filter particles may be coated with a cationic polymer. Another filter block may comprise mesoporous activated carbon filter particles without metallic biocides, wherein the mesoporous activated carbon filter particles may have a median particle size of less than or equal to about 104 μm and a particle span of less than or equal to about 2.05, and wherein at least a portion of the filter particles may be coated with a cationic polymer. The filter block may have a permeability of greater than about 2.0×10−9 cm2 and a Filter Viruses Log Removal of greater than about 2 logs.
