  • Patent number: 7211291
    Abstract: A composite having a plurality of filaments arranged in a fibrous web that is held together in a unitary structure by a domain matrix. The domain matrix comprises a plurality of matrix islands that individually connect, or bond, at least two filaments, to thereby hold the filaments in a unitary structure. Portions of the filament lengths within the unitary structure are free of matrix islands, causing the domain matrix to be discontinuous. The composite possesses a greater flexibility than coated structures. The composite may be formed into cross-plied structures. A method of making the composite also is disclosed.

  • Patent number: 7185778
    Abstract: Barrier units and articles made therefrom, particularly constraining bands of high strength and low weight for containing articles, especially in blast resistant container assemblies, are disclosed. The barrier unit comprises a surface having a regular polygonal perimeter with a plurality of substantially parallel sides, each of which terminates in at least one loop integral with the surface. The surface comprises at least one network of high strength fiber with at least about 50 weight percent of the fiber comprising substantially contianuous lengths of fiber aligned in the hoop direction of the loops. The barrier units have utility as constraining bands for loads of articles like logs, and as doors/closures for access openings to the interior of aircraft blast resistant cargo containers. They are also useful as fences and window protectors.

  • Patent number: 7073538
    Abstract: Bi-directional and multi-axial fabrics, fabric composites, ballistically resistant assemblies thereof, and the methods by which they are made. The fabrics are comprised of sets of strong, substantially parallel, unidirectional yarns lying in parallel planes, one above the other , with the direction of the yarns in a given plane rotated at an angle to the direction of the yarns in adjacent planes; and one or more sets of yarns having lower strength and higher elongation interleaved with the strong yarns. The fabrics of the invention provide superior ballistic effectiveness compared to ordinary woven and knitted fabrics but retain the ease of manufacture on conventional looms and knitting machines.

  • Patent number: 6991124
    Abstract: Blast resistant and blast directing containers, as well as doors and closures therefor, for receiving explosive articles and preventing or minimizing damage in the event of an explosion. The container comprises at least three nested bands of material wherein the bands are oriented relative to one another to substantially enclose a volume and to form a container wall having a thickness substantially equivalent to the sum of the thicknesses of at least two of the bands. The containers have utility as cargo holders, particularly in aircraft where weight is an important consideration, and as transport devices for hazardous materials such as gunpowder and explosives, e.g., bombs and grenades.

  • Patent number: 6969437
    Abstract: Yarn suitable for tufting comprises a base fiber ring spun or wrap spun with a second fiber at least partially comprising a heat-activated adhesive material such that the yarn includes from 0.1 to 12, preferably 0.25 to 10, weight percent adhesive material having a melting point within the range of 105° to 190° C., more preferably 165° to 190° C. A preferred base fiber is a synthetic staple fiber bundle. A preferred wrapping or insert fiber comprises copolyamide material, including ternary copolyamides of the 6/66/12 type. When the yarn is twist set by conventional processes and then tufted into carpet, the resulting carpet displays enhanced wear and appearance properties.

  • Patent number: 6945155
    Abstract: An armor system useful, for example, as a shroud, comprising a first pliable, cut resistant fibrous layer and a second pliable fibrous layer is disclosed. The first layer is arranged to receive an impact from a large projectile prior to the second layer and engages the projectile to slow its velocity. The second layer is substantially coextensive with the first and dissipates the incoming energy of the impact to resist complete penetration of the second layer by the projectile, preferably by deforming in response to the impact. Both layers comprise fibers having a tensile modulus of at least about 200 g/d, and an energy-to-break of at least about 8 J/g and a tenacity equal to or greater than about 10 g/d. In another embodiment, the layers are reversed relative to the impact face of the system so that the second layer becomes the first layer and is resistant to projectiles impacting the system, while the first layer becomes the second layer and resists deformation of the system by projectile impacts.

  • Patent number: 6893730
    Abstract: Oxygen barrier films having a greatly improved dynamic coefficient of friction, and specifically, oxygen barrier films having an exceptionally low dynamic coefficient of friction, reduced moisture sensitivity and good oxygen barrier properties over a wide range of relative humidities. The low coefficient of friction is obtained by using film layers which are blends of a polyamide component and a high density polyethylene which surround an oxygen barrier layer, such as an ethylene vinyl alcohol layer.

  • Patent number: 6887334
    Abstract: A process for forming thin film laminations of thin fluoropolymer films to receiver sheets, more particularly, the production of very thin, transferable fluoropolymer films. A thin fluoropolymer base layer is applied onto a support layer, which may be a thicker film. The support layer/thin base layer is then laminated to a receiver sheet, followed by stripping away the support layer, leaving the base film on the receiver sheet.

  • Patent number: 6872276
    Abstract: A process for transferring a thin polymeric film to either woven or non-woven fabrics by first coextruding the thin polymeric film with a plastic support layer, then adhesively laminating the polymeric film to a fabric, followed by delaminating the support layer. The thin base layer remaining on the fabric imparts desired properties to the fabric while maintaining the soft feel, or drapeability, of the fabric, as opposed to lamination of thicker polymeric films to fabrics.
