摘要： Methods and apparatuses for forming a nonwoven web are described herein. The apparatus includes a mixing partition defining one or more openings therein that permit fluid communication between two fluid flow streams, at least one of which includes a fiber. The apparatus also includes an enclosed region surrounding at least a portion of the mixing partition. The enclosed region is adapted to provide an applied pressure to a fluid flow stream to urge the stream through one or more of the openings in the mixing partition. The apparatus also includes a receiving region designed to receive at least a combined flow stream and form a nonwoven web by collecting fiber from the combined flow stream.

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. A non-woven web can also be made comprising a planar fiber structure having a gradient. Such a web can comprise fibers having diameters that can range from 1 to 40 microns and a second fiber having a diameter that can range from 0.5 microns to about 5 microns. The gradient can change in the cross machine (x-dimension) or across the thickness (z-dimension) increasing or decreasing in either direction. The media of the invention can be used in a variety of applications for the purpose of removing particulates from a variety of gas use on liquid media. Further, the filtered medium of the invention used in a variety of filter element types including flat media, pleated media, flat panel filters, cylindrical spin-on filters, z media pleated filters and other embodiments wherein the gradient provides useful properties. Methods or processes or an apparatuses for forming a nonwoven medium comprising controllable characteristic within the medium are disclosed. The term medium (plural media) refers to a web made of fiber having variable or controlled structure and physical properties.
