Abstract: A tube suitable for use in a vehicular airbag comprises a seamless tube of integral, unitary, one-piece woven construction. The tube defines a pair of opposed panels of substantial area formed in a plain weave of a first yarn density. A pair of intermediate margins of slight width joins an opposed pair of sides of the opposed panels together, the intermediate margins being formed in a plain interweave of a second yarn density greater than the first yarn density. A pair of outer margins is provided, each of substantially greater width than one of the intermediate margins and extending about the outer side of a respective one of the intermediate margins, the outer margins being formed in a weave looser than the plain interweave. The airbag is made by joining a second opposed pair of sides of the opposed panels together to form a bag, inverting the bag and positioning inflation means in gaseous communication with the interior of the inverted bag for inflating the inverted bag.

Abstract: An airbag includes a bag made of a strong, lightweight, thin, flexible fabric of low permeability comprising an uncoated woven cloth characterized by a permeability of not more than one cubic foot of air per minute per square foot of cloth (0.5 cm.sup.3 /sec/cm.sup.2) at a pressure drop of 0.5 inch of water (1.27 cm) across the cloth. The cloth is calendered on both sides to reduce its permeability. The airbag may additionally include a finish of low thermal conductivity disposed on at least the surface of the cloth forming the interior of the bag.

Abstract: A bag suitable for use in a vehicular airbag comprises a seamless bag of integral, unitary, one-piece woven construction. The bag defines a pair of opposed panels of substantial area formed in a plain weave of a first yarn density. A single intermediate margin of slight width joins the peripheries of the opposed panels together, the intermediate margin being formed in a plain interweave of a second yarn density greater than the first yarn density. A single outer margin of substantially greater width than the intermediate margin extends about the periphery of the intermediate margin, the outer margin being formed in a weave looser than the plain interweave. The airbag is made by inverting the bag and positioning inflation means in gaseous communication with the interior of the inverted bag for inflating the inverted bag.

Abstract: A peel ply material of high visual discernibility for use during curing of a resin-coated substrate comprises a base fabric characterized by a high level of wet out when disposed on a cured resin-coated substrate, and tracers woven into the base fabric in spaced lines comprising yarn characterized by (a) a low level of wet out, (b) substantially the same heat shrinkage properties as the base fabric, and (c) a substantially zero transfer level to the resin-coated substrate. The base fabric may be undyed polyester, and the tracers may be bleached polyfluorocarbon or conjugated polyester/carbon.

Abstract: An electrostatic dissipating fabric constructed of a woven or knitted base fabric having an integrally woven or knitted grid structure which is raised above the surface of the base fabric thereby resulting in increased electrostatic dissipation performance. The grid is formed from a static discharge yarn plied to a carrier yarn which is then woven or knitted into the fabric in the warp direction, the fill direction or both, thereby producing a fabric which exhibits the rapid yet controlled dissipation of static electricity into the air. Such fabric can be used for anti-static garments, anti-static covering cloths, filtration media and the like.

Abstract: A directional electrostatic dissipating fabric and method of making such fabric constructed of a woven or knitted base fabric having an integrally woven or knitted grid structure which is raised above only one surface of the base fabric forming a fabric with a raised grid on one side and a smooth or substantially smooth grid on the other side thereby resulting in increased, directional electrostatic dissipation performance from the side having the raised grid. The grid is formed from an electroconductive yarn plied to a carrier yarn which is then integrally woven or knitted into the fabric in the warp direction, the fill direction or both, thereby producing a fabric which exhibits the rapid, yet controlled, directional dissipation of static electricity into the air.
