Abstract: Described herein is a building panel and related building systems, the building panel having a first major surface opposite a second major surface, the building panel comprising a core comprising a first body comprising a first fibrous material; and a second body comprising a second fibrous material, a veneer facing layer coupled to the core, the veneer facing layer comprising a plurality of perforations.

Abstract: An extreme temperature gasket material capable of withstanding temperatures in excess of 850° F. is provided. The extreme temperature gasket generally includes an inorganic filler, an inorganic fiber, and an organic binder. In some embodiments, the inorganic filler is from 75 to 90 wt % of the gasket material and can include submicron-sized talc particles. The inorganic fiber can be from 5 to 20 wt % of the gasket material and can include silicic acid fiber. The binder can be a latex emulsion and can be present in the gasket material in the range of from 1 to 5 wt % of the gasket material. The gasket material also can include additives, such as flocculant and defoamer. In some embodiments, the amount of organic material present in the gasket material is limited to less than 5 wt % of the gasket material.

Abstract: A multi-layer, fluid transmissive structure is provided that comprises first and second fiber layers each comprising a plurality of polymeric fibers bonded to each other at spaced apart contact points. The polymeric fibers of these fiber layers have diameters greater than one micron and collectively define interconnected interstitial spaces providing tortuous fluid flow paths through the first and second fiber layers. The structure also comprises a plurality of nanofibers disposed intermediate at least a portion of the first fiber layer and at least a portion of the second fiber layer.

Abstract: A water felted base mat for a suspended ceiling tile comprising on a weight basis about ½ mineral wool, starch binder, limited to about ?, newsprint, limited to about ?, and about ¼ expanded glass beads.

Abstract: A wet web transfer belt for a closed draw papermaking machine is provided with a rough surface to allow easy release of a wet web. The rough surface is obtained easily, and with reliable quality, by forming the web-contacting side of a batt layer from a welded layer of meltable fiber. A filler is included in the surface portion of the welded layer, extending from the surface at least part way into the welded layer, thereby facilitating the production of projections and concavities which provide the rough surface, and resulting in a wet web transfer belt of stable quality.

Abstract: The present invention provides a fiber product containing a pyroelectric substance and metal ion-holding inorganic particles. With this fiber product wherein the pyroelectric property of the pyroelectric substance is amplified by the metal ion-holding inorganic particles, there can be sufficiently obtained, with no necessity of using a large amount of a pyroelectric substance which is expensive, various effects, for example, activities of ameliorating diseases and promoting health (e.g. acceleration of blood circulation, cure of autonomic imbalance and promotion of metabolism), activity of maintaining the freshness of foods or natural flowers, activity of removing oil or other stains, and microbicidal activity.
