  • Patent number: 6164339
    Abstract: A method of manufacturing a woven textile having a structural member integrally woven therein. The structural member may be either straight or an undulating member which, although straight when secured to the textile, is trained to undergo a shape memory transformation back to its remembered undulating shape. The structural member is secured to the woven textile by displacing one or more given warp yarns in a first direction to create a structural member receiving gap, inserting the structural member into the gap by passing a structural member-insertion shuttle therethrough, and thereafter returning the displaced warp yarn or yarns to secure the structural member.

    Abstract: A fabric according to the invention is made by weaving electrically nonconductive lower ply warp yarns together with electrically nonconductive lower ply filling yarns in a 1/1 plain weave. Within a pattern repeat, 4 electrically nonconductive upper ply filling yarns are additionally interwoven in a plain weave fashion with 4 electrically nonconductive upper ply filling yarns. Two electrically conductive combination yarns, as warp yarns within a pattern repeat, are interwoven with all electrically nonconductive upper ply filling yarns within the pattern repeat into a 2/2 twill weave opposite to the twill woven upper ply warp yarns. The nonconductive filling yarns of the lower ply thus provide an additional supporting effect for the electrically conductive combination yarns. By these means, the electrically conductive combination yarns are stressed substantially less by bending, thus not breaking, whereby the electrical conductivity is thus retained and the functional life is prolonged.

  • Patent number: 4779322
    Abstract: In a crimping process of metal fibers between the engaging pairs of gear rollers, the fibers are first embedded in a ductile and coherent matrix material. After applying a permanent crimping wave deformation on this composite, the matrix material is removed. The crimped fibers can subsequently be transformed to a metal fiber web. They can also easily be blended with textile fibers in order to form, e.g., antistatic blended yarn.

  • Patent number: 4746769
    Abstract: A multilayer woven high density electrical transmission cable (A) is disclosed including a first woven cable layer (D) and a second woven cable layer (E) bound together by warp bindings (24) as integral cable structure. Signal conductors (16) and ground conductors (18) extend in the warp direction in cable layer (D). Signal conductors (26) and ground conductors (28) extend in the warp direction in cable layer (E). Signal conductors (16 and 26) are broken out of their respective cable layers either on opposite sides, breakout sections (B,B'), or at the same sides, breakout section (B") as required for a prescribed program termination. All of the ground conductors (18 or 28) of one cable layer cross over to the side of the other cable layer so that one-hundred percent of the ground conductors (18 and 28) are on the same side at the breakout section for termination. The density of the signal conductors is doubled for a given cable width while affording signal identification for a prescribed termination program.

  • Patent number: 4664158
    Abstract: An elastic conductive fabric for use as a grounding strap and the method of making the same are disclosed. The fabric is woven utilizing elastic yarn ends intermingled with conductive yarn ends. The weaving process is carried out while the elastic yarn ends are distended by at least 150% and preferably 250-400% as compared with the relaxed condition thereof. Preferably the conductive yarn is woven in a two over one pattern so that when tension is released in the elastic ends, the crests of the conductive ends which span two picks will project a substantial distance from the fabric surface. The opposite face of the fabric may be comprised of insulative ends likewise woven in a two over one pattern to provide enlarged crests at said face. Locking yarn ends maintain the conductive crests in a perpendicular condition relative to the fabric body.

  • Patent number: 4653473
    Abstract: A method of reducing pain resulting from exposed or damaged nerve ends, such as the pain in amputees commonly referred to as phantom limb pain is disclosed. The method may also reduce pain resulting from arthritis. This method involves covering the affected area with a radiation-shielding textile, whether by fashioning a garment from the textile or using a sheet or cover. The radiation-shielding textile found to be suitable is a cloth woven of yarn consisting of a textile fibre, such as nylon, and from two to thirty-five percent by weight of conductive metal filament.

  • Patent number: 4606968
    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.
