    摘要： A multi-faceted family of non-woven webs that can take the form of a filter media, an adaptable forming process and a machine capable of making the range of media are disclosed. The filter medium can have a first surface and a second surface defining a thickness. The medium can comprise a region having a gradient. Such a gradient is formed by having a medium wherein the concentration of a fiber, a property or other component varies from one surface to the next surface. The gradient region of the media can comprise the entire thickness of the medium or can comprise a region that comprises a portion of the media thickness. The media are characterized by the presence of a continuous change of the fiber concentration or property within the region.

    摘要： Wiping products are disclosed containing an additive composition that enhances the cleaning properties of the product. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition increases various properties of the product including the ability of the product to quickly absorb oil. For instance, the additive composition can decrease the Oil Absorbency Rate by from about 20% to about 80% and can decrease the Reverse Osmosis Oil Wet Out time by from about 10% to about 80%.
