Abstract: Vehicle air bags are constructed of fabric produced according to improved methodology. The fabric, which may be coated or uncoated, is dry woven on a loom machine without size. Since size is not used, the invention provides several methods to reduce chafing of the unprotected yarn during the weaving process. For example, the yarn is preferably of a type having a relatively large number of evenly-spaced nodes of entanglement. The warp ends are preferably beamed at a ratio of no greater than two ends per dent of the beaming comb. At least six (6) weaving harnesses are preferably used on the loom as the fabric is being produced. Because size is eliminated, the fabric does not have to be scoured prior to use. As a result, the air permeability of the fabric remains naturally low and fabric stiffness is reduced.

Abstract: The floss is comprised of a texturized yarn that has been coated and impregnated with a water-soluble polymer and the water-soluble polymer coating cured and set while the yarn is stretched and is under tension. The yarn while stretched and tensioned is at a reduced width, which allows for easier insertion of the yarn floss between teeth. The yarn floss is wound onto a spool in the decreased width condition. For use, a length of floss is removed from the spool and placed between teeth. The saliva in the mouth dissolves the cured and set water-soluble polymer with the floss expanding to fill the space between the teeth. The floss is optionally coated with flavors, medicants and other substances. These can be synthetic or naturally occurring substances such as herbal substances.

Abstract: A radiator hose is provided with an inner tube rubber and a cover rubber. The inner tube rubber is coiled on the outer circumference with filament yarns made of nylon 6,6 separating predetermined spaces each other. The filament yarns are twisted at predetermined twist number before coiling, and pass through an adhesive agent supplying step, a dry-heating step while applying tension to the filament yarns and reel-hank steps, and goes into a wet-heating step. For the wet-heating step, the filament yarns are given temperature equivalent to a vulcanizing temperature, applying no tension to the filament yarns. By the wet- and dry-heating, the filament yarns are prevented from biting into the inner tube rubber. Since the filament yarns are immersed into the solution of an adhesive agent before the dry-heating, the solution attached on the filament yarns is dried off rapidly by the dry-heating thereafter.

Abstract: A process for placing an ultra thin layer of a non-porous gas permeable polymer continuously over an entire filter surface area allows the fabrication of compact, high flux, fouling resistant gas filters. The process involves contacting a dilute coating solution of gas permeable polymer in a solvent with one side of a microporous substrate. The pore size of the substrate is chosen for its ability to effectively filter the gas permeable polymer from the coating solution. Solvent of the coating solution is made to flow through the microporous substrate which causes an ultra thin layer of polymer to build up on the side of substrate. When a desired thickness of polymer is built up, the solution and solvent is removed and residual solvent is evaporated, preferably by passing a gas at high rate over the surface of the polymer layer.This process can be used to coat flat sheet and hollow fiber substrates.

Abstract: A method and apparatus for coating and drying coated substrates without introducing significant surface imperfections while running at higher web speeds than known drying methods. The substrate is preferably coated within the drying enclosure or the coating bead may form a closure at the entrance of the drying enclosure. The substrate is moved through a first drying enclosure along a first axis. The first drying enclosure is substantially isolated from an external environment. A first low velocity, substantially laminar flow field of a drying gas is directed across the front surface of the substrate. The first flow field is generally parallel to the front surface and generally perpendicular to the first axis to minimize the formation of surface imperfections during the evaporation of the coating solvent. The substrate may then be moved to subsequent drying enclosures through transition enclosures that minimize surface imperfections due to high velocity interaction between the adjacent drying enclosures.

This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets.

Useful oxidants include inorganic chlorate salts such as sodium chlorate.
