Abstract: A lightweight coated fabric substrate of high tenacity yams, such as nylon, polyester, polypropylene or the like is extrusion coated with a material resulting in a substantially air impermeable fabric with a tear strength-to-weight ratio of at least 8 pounds/oz. per sq. yd. at weights of between 2 and 7.5 oz. per sq. yd.

Abstract: A method for reinforcing fabric edges to prevent raveling or fraying of a release liner fabric during cutting and subsequent use. The method is carried out by coating the yarn crossovers with a flexible, thin film of a radiation polymerized resin and then curing the coating system at high production speeds. The fabric is cut in those areas where the cured coating is applied, thereby providing a band or border of cured resin of sufficient width to prevent raveling of the fabric edge. The method is particularly suitable for the fabrication of release liners used for the protection of rubber sheeting for manufacturing automobile tires.

Abstract: A method and apparatus for extrusion coating a nylon fabric or the like. The apparatus includes a supply roll for supplying a length of fabric having a top and bottom surface and a take-up roll for taking up the length of fabric. An extrusion coating head located between the supply roll and the take-up roll and perpendicular to the movement of the length of fabric applies a plastic coating onto one surface of the length of fabric. A combining roll located between the supply roll and the take-up roll and adjacent to the extrusion coating head joins the plastic coating to the one surface of the length of fabric. In the preferred embodiment, the combining roll is heated to provide improved adhesion of the plastic coating onto the surface of the length of fabric while, at the same time, a water mist prevents sticking. The resulting fabric has a tear strength of greater than about 50 pounds and a weight of less than about 5.5 oz. per sq. yd.

Abstract: A process of reinforcing airbag fabric edges to prevent raveling or fraying of the fabric during the cutting process. The process is carried out by coating the yarn crossovers with a flexible, thin film of a radiation polymerizable resin and then curing the coating system at high production speeds. The airbag fabric is cut in those areas where the coating has been applied and cured, thereby providing a band or border of cured resin of sufficient width to prevent raveling of the airbag fabric edge. The process is particularly suitable for the fabrication of airbags used for the protection of vehicle occupants as in automobiles. Airbags constructed of a breathable, edge-coated fabric are also described.

Abstract: A heat stable molded phenolic resin article comprising, in percent by weight, from about 20 to about 70 percent of an oil unmodified phenolic resin, from about 3 to about 25 percent of an acrylonitrile-butadiene elastomer, and from about 15 to about 70 percent of a silicate mineral. Also a molding composition comprising, in percent by weight, from about 20 to about 70 percent of an oil unmodified phenol-aldehyde thermosettable resin, from about 3 to about 25 percent of an acrylonitrile-butadiene elastomer, and from about 15 to about 70 weight percent of a silicate mineral.
