  • Publication number: 20050118716
    Abstract: Methods and structures are disclosed where carrier fiber is used to enable the assembly of two and three dimensional structures of autologous tissue. Tissue is harvested from the donor, integrated with a carrier fiber, and assembled into complex forms rapidly. The structures can be tailored to the requirements of a specific medical procedure. The tissue is kept live and viable during extracorporeal assembly and the finished structure is emplaced in the donor's body. The use of a carrier fiber leader for pre-threading integration and assembly machines facilitates machine set up, drawing of the tissue into the process, and rapid integration and assembly of the multi-dimensional structures. Assembly can include providing tissue and fiber leaders extending from the structure for attaching the structure in place. The carrier fiber either is bio-absorbed as new tissue forms, or forms a bio-compatible substructure for the patient's native tissue.

  • Patent number: 6861120
    Abstract: A protective covering system having high-flexibility and low areal density characteristics. In one aspect of the invention, the protective system includes a plurality of metallic staples or wire elements secured to multi-layer matrix including woven fibers, the layers being oriented at cross angles to provide a grid-like pattern of protective elements. In one aspect of the invention, protective elements provide a coverage area of less than 90% and as little as 40% of total surface area. In one aspect of the invention, protective elements may be mechanically secured to a matrix by a puncture and crimp process. In another, wire elements may be attached or woven into one or more matrix layers.

  • Patent number: 6834685
    Abstract: A fabric system and manufacturing method for achieving higher fiber crimp in selected fibers to reduce initial fabric modulus (gain higher elongation) in the thread-line direction. The fabric system and method utilizes processing yarns of higher shrinkage than the product reinforcing yarns. The processing yarns are woven together with the reinforcing yarns in various patterns and combinations dependent on the desired fabric characteristics. The fabric is processed thermally or otherwise to impart crimp into the reinforcing yarns by the differential shrinkage of the processing yarns. By adjusting the ratio of reinforcing yarns to processing yarns, a unique set of characteristics in the fabric is created, specifically a lower modulus, higher initial elongation in the thread-line direction of the reinforcing yarn.

  • Publication number: 20040151865
    Abstract: A method for joining fabrics, particularly high strength fabrics such as airship hull fabrics, including the steps of: measuring selected parameters of two fabric layers to be joined and the adhesive and any tape or other materials intended to be included in the joint; calculating therefrom an optimal value of a quality control parameter of an ideal joint, such as joint thickness, specific gravity or opacity; assembling the two fabric layers and other materials in the desired order; and applying heat and pressure to the assemblage until the selected quality control parameter of the joint, such as joint thickness, specific gravity or opacity, is satisfied.

  • Patent number: 6720277
    Abstract: A protective fabric of high penetration resistance is formed from a plurality of layered, densely woven base fabrics, each formed by tightly weaving multifilament yarns to obtain a warp yarn “density” or “cover” in excess of 100% at the center of the fill yarn, and a fill yarn density or cover preferably also in excess of 75%. The yarns themselves preferably comprise a high modulus, high breaking strength yarn of materials such as Kevlar, Spectra, or Vectran. The resultant layered fabric offers especially high penetration resistance to weapons such as ice picks and the like. Additional resistance to penetration by sharp knives is provided by interruptedly coating the base fabric with an epoxy in such a manner as to inhibit penetration while providing drapability and breathability.

  • Publication number: 20020124904
    Abstract: The present disclosure describes puncture-resistant fabric layers comprising woven fabrics with unique, densely-woven structures. For example, such a fabric layer ca comprise a high cover factor woven fabric having a fill yarn cover factor of at least about 75% of full and a warp yarn cover factor of at least about 100% of full formed of a plurality of fill yarns and a plurality of warp yarns, wherein the weight per unit length of the fill yarns is less than the weight per unit length of the warp yarns. Such constructions can, in some embodiments, consist essentially of high tenacity fibers having a tensile breaking strength of at least about 10 g/Denier. Such high cover, small fill yarn constructions enable the disclosed fabrics to be woven to have a decreased overall weight per unit surface area and an improved tensile balance, when compared to known high cover factor, densely woven fabric constructions.

  • Publication number: 20020111099
    Abstract: A variety of methods of improving the dyeability and printability of fabrics comprising or consisting essentially of high tenacity fibers having a tensile breaking strength of at least about 10 g/Denier are disclosed. Such methods can result in fabrics, yarns, and/or fiber bundles having an improved ability to be dyed and/or printed with a printed pattern (e.g., a camouflage pattern), when compared to typical high tenacity fiber-based fabrics known in the prior art. The fabrics can have dyeability characteristics enabling them to be dyed with a variety of commercially relevant fabric dyes, such that the fabrics, after exposure to the dyes, are characterized by an essentially visually uniform dyed color density. In one embodiment, a dyeable fiber bundle, which can be utilized to form dyeable yarns and fabrics, which comprises at least about 5% of high tenacity fibers having a tensile breaking strength of at least about 10 g/Denier is disclosed.

  • Publication number: 20020016118
    Abstract: A laminate is disclosed for high strength, low weight gas enclosure applications such as aerostats or airships. The laminate is formed of at least one woven fabric layer with an aggregate strength greater than 10 grams per denier. The yarns in the fabric have sufficient twist to provide the desired tensile conversion but less than the amount of twist that would produce unsatisfactory flex fatigue. The fabric has a yarn to fabric strength ratio sufficient to impart tear resistance to the fabric, but less than the coarseness ratio at which flex fatigue performance is unsatisfactory, and the fabric has the minimal number of crossing points among the woven yarns that will impart sufficient integrity for the fabric to be manufactured into the laminate. A gas barrier material is then laminated to the fabric layer.
