摘要： Disclosed is a battery separator, comprising two fiber regions comprising glass fibers, and a middle fiber region disposed between them comprising larger average diameter fibers and specified amounts of silica, or fine fibers, or both; and processes for making the separator. Also disclosed is a battery separator, comprising a fiber region and either one or two silica-containing region(s) adjacent thereto, each of the regions containing a specified amount of silica; and processes for making the separator. Such separators are useful, e.g., in lead-acid batteries.

摘要： Fiber webs that include an acid scavenger are provided. In certain embodiments, the acid scavenger may be immobilized within a resin and/or on the fiber web. In some embodiments, such fiber webs are used in filter media. The filter media may be suitable for filtering fluids that contain one or more acids. The acid scavenger may serve to complex and/or neutralize acids in the vicinity of the fiber web, thereby rending the fiber web more durable against degradation in acidic environments. The respective characteristics and amounts of the acid scavenger on the fiber web may be selected to impart desirable properties to the fiber web, including enhanced mechanical and performance properties (e.g., relatively high strength and lifetime) during filtration. Filter media formed of the fiber webs may be particularly well-suited for applications that involve filtering lubricating oil or hydraulic fluids, though the media may also be used in other applications.

摘要： Disclosed is a battery separator, comprising a coarse fiber region comprising fibers, such as glass fibers, having an average diameter of greater than or equal to 2 μm; a first fine fiber region comprising glass fibers having an average diameter of less than or equal to 2 μm, and a second fine fiber region comprising glass fibers having an average diameter of less than or equal to 2 μm, wherein the coarse fiber region is disposed between the first fine fiber region and the second fine fiber region, and wherein the thickness of the coarse fiber region constitutes 1-49% of the sum of the thicknesses of the coarse fiber region, the first fine fiber region and the second fine fiber region. Such a separator is useful, e.g., in a lead-acid battery, where during filling of the battery with acid, the separator enhances the diffusion of acid toward the interior region.

摘要： Filter media, including those suitable for hydraulic applications, and related components, systems, and methods associated therewith are provided. The filter media described herein may include two or more layers, at least one of the layers having a relatively high percentage of microglass fibers. Additionally, the filter media may be designed such that the ratio of average fiber diameters between two layers is relatively small, which can lead to a relatively low resistance ratio between the layers. The filter media has desirable properties including high dirt holding capacity with low basis weight and a low resistance to fluid flow. The media may be incorporated into a variety of filter element products including hydraulic filters.

摘要： Water dispersible fiber products are provided. In one embodiment, a water dispersible fiber sheet is provided and it is preferably formed from regenerated cellulose fibers, a second fiber that is adapted to provide strength to the water dispersible fiber sheet, and a water soluble binder. In use, the fiber sheet can be formed into a variety of products including, for example, for labels, packaging, medical and health care products. The fiber sheet is particularly advantageous in that it is readily dispersible upon contact with water, yet it will retain its strength when used with other fluids, such as alcohol and oils. The biodegradability of the fiber sheet will also allow the fibers to be consumed naturally by environmental bacteria, thus eliminating the need for special disposal procedures. In another embodiment, the water dispersible fiber sheet can be incorporated into a filter media.

摘要： A glass fiber separator material is disclosed. The separator is composed of a mass of intermeshed glass fibers substantially all of which have a fiber diameter not greater than about 20 νm, and at least 5 percent w/w of which have a fiber diameter less than 1 νm, and, distributed through the glass fibers, and from 0.2 percent w/w to 20 percent w/w of cellulose fibrils. The fibrils are from a slurry having a Canadian freeness sufficiently low that the separator material has a tensile strength greater than on otherwise identical separator where glass fibers having an average diameter greater than 1 νm replace the cellulose fibrils.
