    Abstract: A method of manufacturing a fabric (56) for filtering particulate laden air needles at least one layer of batting (20) (e.g., fibrous material) with a layer of electrically conductive material, such as metallic foil (42), thereby entangling fibers of the batting (20) and shredding the metallic foil (42). In a preferred embodiment, a scrim (24), which is a grid made of cloth, and at least one layer of metallic foil (42) are sandwiched between two layers of batting (20, 50). In a needling process, a bed of barbed needles (55) are repeatedly and rapidly thrust into and pulled out of the layers, thereby entangling fibers of the bats (20, 50), both with each other and the scrim (24), and shredding the layer of metallic foil (42). The resulting fabric (56) has metallic filaments or fibers (62) substantially evenly dispersed therein. The fabric (56) is used for particulate collection on filters (66).

    Abstract: A laminated product has an organic polymer layer on at least one surface of a substrate of cellulosic material impregnated with polyisocyanate. The substrate is preferably made from substantially delignified cellulosic material and an isocyanate resin. The isocyanate resin comprises a polyisocyanate, preferably PMDI, and may include a miscible organic solvent, preferably one such as propylene carbonate having a high boiling point and low flammability and toxicity. The substrate may be cured with an uncured overlay sheet positioned on the cured substrate and then cured to bond the substrate and overlay. Alternatively, a cured overlay may be adhesively or otherwise secured to a previously cured substrate. As yet another alternative, an uncured overlay sheet and uncured substrate may be placed in position and simultaneously cured. An overlay may be positioned on one or both major surfaces of a substrate sheet.

    Abstract: A rigid structural panel (10) made from the rinds of sugarcane, sorghum and similar grasses. The panel is formed of a pile of long, generally straight rind fiber-bundle strands (12) randomly oriented in generally parallel planes, each strand coated by a binder which connects it with other strands at many contact points (16) along its length to form voids (18). A method and apparatus for making such panel, the method including pressing a loose pile (58) of coated strands to a final thickness and curing to interconnect the strands, the curing step preferably including moving air through the pile as it moves and is pressed between a pair of perforated belts (48, 62).

    Abstract: A dimensionally stable carpet tile having a greige good adhered to an aqueous wet-laid composite sheet comprising dimensionally stable reinforcing fiber in an amount sufficient to provide less than a 0.1 percent dimensional change of the carpet on an Aachen Test. Typical dimensionally stable reinforcing fibers are glass fibers and/or polyester fibers employed in amounts from 2 to 15 percent by weight based on the total composite sheet. The other main ingredients of the composite sheet comprise from 1 to 30 percent cellulose fibers, 2 to 30 percent organic polymer binder material and 60 to 95 percent inorganic filler based on the total weight composite sheet. The composite sheet has an internal bond strength of at least 50 grams per inch (19.68 g/cm).
