Abstract: Articles such as filter media, which include dendrimers and/or other components, are provided. The filter media may further include a water repellant (e.g., a fluorinated species) to impart desirable properties to the media such as high water repellency. The filter media may also have a high efficiency as a function of pressure drop (i.e., high gamma values). In some embodiments, the filter media includes a fiber web which may be formed of various components such as glass fibers. The fiber web can also include additional components such as synthetic fibers, binder components, as well as other additives. The media may be incorporated into a variety of filter element products.

Abstract: The present invention concerns a binder for a mat of fibers, especially mineral fibers, which comprises: at least one monosaccharide and/or at least one polysaccharide; at least one polycarboxylic organic acid with a molar mass of 1000 or less; and at least one vinyl acetate homopolymer or copolymer. It also concerns the products resulting from treatment of the fibers, especially mineral, with said binder.

Abstract: A siding panel assembly includes an ornamental facing and a first insulation layer made from fibrous insulating material. That fibrous insulating material includes polymer fibers and glass fibers, polymer fibers, natural fibers and mixtures thereof. A method for making the siding panel assembly includes the steps of cutting a groove in and molding a first surface of a sheet of the insulation layer to match in profile a concavity in the ornamental facing and assembling the insulation layer and the ornamental facing.

Abstract: Insulation for high temperature applications includes glass fibers having an average diameter of between about 2.7 to about 3.8 microns. In one possible embodiment the insulation includes a polyacrylic acid binder. Such insulation has about 98 weight percent glass fibers and about 2 weight percent binder.

Abstract: An arrangement for producing a fibrous mat from a heated die source wherein the produced mat includes a first layered, preselected fiber portion of substantially straight fibers produced by directing such fibers directly to a collector source and a second layered preselected fiber portion of substantially curled fibers produced by diverting and exerting an external vortically creative curling force thereon before reaching the collector source.

Abstract: This invention relates to a composite laminate, a layup and preform for such a composite laminate and to a method of manufacturing the composite laminate. The layup (28), preform and composite laminate (22) include at least one ply (20) which includes hairy yarn (10). The action of the hairy yarn (10) is to provide cross ply linking owing to the extension of fibers from the hairy yarn into spaces both within the ply and between the plies. The addition of resin matrix material (26) to layup provides a firm cross ply linkage to the composite laminate.

Abstract: A mat of mineral fibers has a random or quasi-random fiber orientation. The fibers have diameters which, for the great majority of them, are 2.5 to 4.5 micrometers, and a length of 2 to 15 cm. Its density is less than 40 kg/m3. Its resistance to compression, for a crushing of 10%, is equal to at least 0.5 kN/m2. The fineness of the fibers and their random distribution imparts to the mat an exceptional lightness and an excellent flexibility, making possible the perfect application of the mat on cylindrical surfaces.

Abstract: The invention concerns a web comprising an intimate mixture of mixed slivers of long reinforcing staple fibres (14) obtained by stretch-breaking and long thermoplastic matrix fibres (15), those different fibres being parallel in the mixture.

Abstract: Dual glass fibers can be processed into coherent webs and felts by first blending the dual glass fibers with an equal or greater amount of uncrimped fibers. Optionally, other crimped fibers can be added without significant impact on processibility.

Abstract: A filter composite comprises a first layer of glass fibers having random orientation, and synthetic resinous fibers extending in close association with the glass fibers, the glass fibers having: i) diameters between 1 and 16 microns ii) lengths between about ¼ and 1½ inches the synthetic fibers having denier between 1.6 and 40, and length between ¼ and 2 inches.

Abstract: Carbon fiber sheet materials having improved dimensional stability and ease of handling are provided. The sheet materials include a carbon fiber network and an adhesive polymeric material adhered to at least one surface of the carbon fiber network. The invention further provides methods of making the carbon fiber sheet materials, as well as electrodes and electrical energy storage devices which include the carbon fiber sheet material as a component thereof.

Abstract: An aqueous composition suitable for use, when dry, as an improved elastomeric coating, caulk, sealant, fabric treatment, or pressure sensitive adhesive is provided including a predominantly acrylic aqueous emulsion polymer, the polymer having a glass transition temperature (Tg) from −90° C. to 20° C., formed by the free radical polymerization of at least one ethylenically unsaturated nonionic acrylic monomer and 0-7.5%, by weight based on the total weight of said polymer, ethylenically unsaturated acid monomer until 90-99.7% of said monomers by weight, based on the total weight of said polymer, has been converted to polymer and subsequently at least half of the remaining monomer is converted to polymer in the presence of 0.01-0.099%, by weight based on the total weight of said polymer, t-alkyl hydroperoxide, t-alkyl peroxide, or t-alkyl perester wherein the t-alkyl group includes at least 5 Carbon atoms or, alternatively, the polymer is formed in the presence of 0.01-1.
