Abstract: A dual-layer fabric for reinforcing resin composite panels. The fabric includes a first layer and a second layer. Warp and weft yarns are interwoven with each other to form each of the first layer and the second layer. The warp yarns include both aramid yarns and high temperature organic yarns. The weft yarns include both aramid yarns and high temperature organic yarns.

Abstract: A preformed insulation mat is provided for use between the inner and outer end cone housing of a pollution control device. The preformed insulation includes a frustum-shaped mat. The mat is formed of primarily heat moldable, silica based glass fibers containing Al2O3 and is molded at a selected temperature and for a selected time duration to heat set the fibers, whereby the frustum-shaped mat is seamless and self-supporting, requiring no shape no shape retaining elements or chemical binders.

Abstract: A bag house filtration system in which the filter media includes a woven textile formed from glass yarns other high temperature resistant yarns. A first bath is applied to the textile which contains a conductive component, a first fluoropolymer and a lubricant (in some cases where the yarns are glass). A second bath containing primarily a second fluoropolymer is then applied to the textile and the first composition to seal the first composition on the textile. The textile, so treated dissipates the static electricity normally generated in the filter media thus reducing excessive buildup of contaminating particles and enhancing cleaning of the bag during use.

Abstract: A method is provided for forming a relatively thick, lightweight, nonwoven insulating mat. The method includes the steps of forming a relatively thin, relatively dense first outer layer by needle punching a first batt of glass fibers and forming a relatively thin, relatively dense second outer layer by needle punching a second batt of glass fibers. A relatively thicker, relatively less dense intermediate batt of glass fibers is fed between the first and second layers. Thereafter, the first layer, intermediate batt, and second layer are needle punched together to form a multi-layer mat having a first layer, middle layer, and second layer.

Abstract: An abrasion resistant and chemical resistant damper is provided for installation in the sludge transport section of a wastewater treatment system of the type having a damper inlet chute and a damper outlet chute and a damper between the damper inlet chute and the damper outlet chute. The damper is formed from a fabric woven substantially of yarns of high performance material selected from the group consisting of aramid, ultra-high molecular weight polyethylene, and liquid crystal polymer. The damper includes a body having an inlet end and an outlet end, whereby the body creates a volume for sludge to move through. An inlet flange is formed about the inlet end and an outlet flange is formed about the outlet end.

Abstract: A fabric material for high temperature gaseous filtration applications, including a fabric material capable of withstanding temperatures of at least 450 degrees Fahrenheit for prolonged periods without deformation or deterioration, and a chemical stiffener that has been applied to the fabric.

Abstract: A process for the drying of woven glass fabric to be used in a reinforcing laminate in sensitive electronic equipment is disclosed. The process adopts a drying technique of utilizing dielectric or radio frequency heating which results in a cleaner product.

Abstract: A cable wrap fabric for protecting a communications cable is woven of fiberglass yarns plied with or without low melt thermoplastic yarns, and water swellable superabsorbent yarns. The water swellable superabsorbent yarns are interspersed at spaced intervals within the fiberglass yarns. The fiberglass yarns dissipate heat energy created by lightning strikes or excessive thermal shocks. The superabsorbent water swellable yarns block the progression of water through the cable. The low melt thermoplastic yarns, if used, fuse the other component yarns of the fabric together so that the fabric can be slit into the required tape widths without excessive yarn fraying at the edges.

Abstract: The present invention is directed to a fabric capable of reflecting electromagnetic waves. The fabric contains metal-coated (preferably aluminum) glass fibers bonded together with sheath-core binder fibers. The glass fibers are typically less than 11/4 inches long and the binder fibers are originally approximately 2 inches long. The glass and binder fibers are thoroughly mixed and spread across a flat surface, such as a conveyor, prior to heating. After heating, the mixture is compressed to form the reflective fabric.

Abstract: Smoke containment curtains formed of flexible, smoke impermeable fabric formed of a fiberglass fabric substrate coated with a smoke impervious composition on at least one side. The coating includes a halide-free fire retardant incorporated into a halide-free acrylic or silicone resin. The resulting fabric has an LC.sub.50 of greater than 50 grams.

Abstract: Feathered edges of fiberglass fabrics woven on a shuttleless or airjet loom are secured and prevented from ravelling by a glass yarn coated with a hot melt composition. The coated yarn is woven along the longitudinal edges of the fabric, typically in a leno weave, then heated to thermobond the adjacent glass fibers with the hot melt composition at their crossover points. A procedure for applying a hot melt to a yarn through a heated die is used.

Abstract: A yarn with a smooth coating is produced by coating a yarn with a thermoplastic material in the melt state, drawing the coated yarn through a heated dye, and cooling the coating.
