Abstract: Fabric and reinforcements are provided by this invention which, in a first embodiment, include a plurality of warp yarns having a first twist (turns/inch) and a plurality of weft yarns having a second twist which is greater than the first twist. A coating is applied over a substantial portion of the warp and weft yarns after they are assembled or laid together, so as to produce a weight distribution ratio of less than about 2.0:1, based upon the weight of the resinous coating of the weft yarns over the weight of the resinous coating on the warp yarns. This can be achieved, in substantial part, due to the difference in the twist ratios of the warp and weft yarns, which difference permits a more uniform coating to be applied. Further embodiments of this invention include a cementitious board and methods of making a coated fabric and cementitious board.

Abstract: This invention provides facing materials for cementitious boards such as those including Portland cement or gypsum cores. The preferred facing material includes, in a first embodiment, a facing layer having an areal weight of about 300 grams/M2, and an air permeability rating of no greater than about 300 CFM/ft2 (FG 436-910 test method). The facing layer reduces the penetration of a slurry of cementitious material during the manufacture of a cementitious board, while permitting the water vapor from the slurry to pass therethrough. The facing materials of this invention can be designed to substantially eliminate the fouling of rolls used in continuous processing of such boards without the use, or with greatly reduced use, of costly viscosity control agents in the slurry.

Abstract: A method of making a membrane assembly by forming at least a pair of bottom sheet membranes and at least one top sheet membrane, wherein the bottom sheet membranes are adapted to attach to and cover respective pavement sections of a roadway, and constructing each top sheet membrane with a track, wherein each track receives edges of a corresponding pair of the bottom sheet membranes.

Abstract: Packaging rolls and a method of packaging rolls of textile fabric are provided in which a roll of textile fabric having first and second transverse ends and a longitudinal length is inserted within a polymeric bag disposed over the roll. The polymeric bag includes a reclosable closure strip comprising at least one rib and one groove oppositely disposed on an inner surface of the polymeric bag proximate to the bag opening. The polymeric bag is designed to provide water and abrasion resistance to rolls of textile goods of about 3–16 feet in length and about 6–24 inches in diameter. The bag can also be reused for partially used rolls.

Abstract: The present invention relates to a composite sheet material that is water vapor permeable and substantially liquid water impermeable. The composite sheet material includes an outer layer, a film, and a reinforcing layer and, preferably, has an ASTM D3833 water vapor transmission rate of greater than 250 g/m2/day, and a tensile strength of at least about 100 N/5 cm when tested in accordance with ASTM D5035. The sheet material is useful as a membrane for roofing, housewrap, insulation facing and in the fabrication of protective apparel.

Abstract: Drywall tapes, drywall joints and methods for their construction are provided by this invention. The drywall tape of this invention includes a web of glass fibers and a coating disposed over a portion of the glass fibers. The coating includes a resinous binder which is at least partially soluble or dispersible in joint compound. The resinous binder is capable of forming an adhesive bond with the joint compound when set.

Abstract: Inversion liners are provided which in a first embodiment include first and second flexible fabric layers separated by one or more glass fiber containing layers and joined in tubular form. The second flexible fabric layer further is bonded to a third flexible fabric layer comprising a substantially fluid impermeable layer. An invertible glass-faced liner is also provided by this invention which includes a glass facing on one side and a substantially fluid impermeable layer on the other. The substantially fluid impermeable layer is joined to a flexible fabric layer which is preferably heat bonded to a thin veil joined to a second glass containing layer of this liner embodiment. The inversion liners of this invention can be built-up in multiple layers or blocks to meet end-use design demands while still providing flexural moduli in excess of 500 ksi, preferably about 700-800 ksi.

Abstract: This invention provides multi-layered composites, laminates and composite joints in which at least one resin-impregnated, fiber-containing layer is joined or laminated to a core layer having a lower flexural modulus or higher elongation at break, higher toughness, or a combination of all or some of these properties. The multi-layer composite produced by laminating or joining these materials together has improved shearout, impact and cutting resistance, since stresses caused by outside forces can be more widely distributed throughout the composite.
