  • Patent number: 7087300
    Abstract: Fire retardant and heat resistant yarns, fabrics, and other fibrous blends incorporate one or more fire retardant and heat resistant strands comprising oxidized polyacrylonitrile and one or more strengthening filaments such as metallic filaments (e.g., stainless steel), high strength ceramic filaments, or high strength polymer filaments. Such yarns, fabrics, and other fibrous blends have a superior tensile strength, cut resistance, abrasion resistance, LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, and other fibrous blends are also more soft, supple, breathable and moisture absorbent and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The inventive yarns may be woven, knitted or otherwise assembled into a desired fabric or other article of manufacture.

    Abstract: Durable antimicrobial treatments for high pressure treatments (such as package dyeing) for specific dyed yarns for further incorporation within textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder as a component of the dye bath formulation admixed with the silver-ion antimicrobial compound, the formulation then forced through a target yarn spool in order to provide a finish over substantially all of the target yarn. The yarn may then be knit, woven, pressed, laid-in, etc., into a textile fabric exhibiting antimicrobial properties. Such a treatment has been found to be extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity.

  • Patent number: 6413637
    Abstract: Metal cord for use in reinforcing fabric for articles made from rubber, such as pneumatic tires, conveyor belts, flexible tubes, and similar, comprising a plurality of such metal cords orientated parallel to each other in a single direction and in which each cord comprises metal wires wound spirally around each other, wherein at least one of the wires of the cord consists of a shape memory material. During the phase of incorporation of the cords into the elastomeric material, the shape memory wire tends to recover the shape memorized initially and, by means of the force generated during this recovery, transmits by friction to the surrounding wires forces tending to shorten the pitch of the cord with spacing of each wire from the next, resulting in good penetration of elastomeric material between the wires. The closure of the cord is maintained in the subsequent heat cycles, owing to the memory degradation characteristics imparted to the wire.

  • Publication number: 20020012795
    Abstract: A coated cable includes a structural core made of twined wire or other suitable material, and an outer layer surrounding the structural core, such outer core being transparent to light. The cable further provides a material which is reflective to incident light, effective to reflect light from the cable in a manner discernable to an observer. In an advantageous embodiment, this is accomplished by a reflective layer interposed between the structural core and the outer layer, the reflective layer being provided in the form of a wrapped tape disposed below the outer layer.

  • Patent number: 6287686
    Abstract: Fire retardant and heat resistant yarns, fabrics, felts and other fibrous blends which incorporate high amounts of oxidized polyacrylonitrile fibers. Such yarns, fabrics, felts and other fibrous blends have a superior LOI, TPP and continuous operating temperature, compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous: blends are also more soft and supple, and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous blends incorporate up to 99.9% oxidized polyacrylonitrile fibers, together with at least one additional fiber, such as p-aramid, in order to provide increased tensile strength and abrasion resistance of the inventive yarns, fabrics, felts and other fibrous blends. The yarns may be woven, knitted or otherwise assembled into a desired fabric.

  • Patent number: RE37430
    Abstract: Cut resistant, abrasion resistant and electrically conductive yarns (1) are formed in torque-free form from stainless steel and other metallic yarns (2) served with or formed into composite twists with non-metallic yarns and fibers (4) and (5). The metallic yarn (2) is made up of at least about 60 ends, and up to as many as about 300 ends, of metal fibers (3) having a diameter of from about 2 to about 25 &mgr;m. The absence of torque permits facile knitting into protective garments, such as cut resistant, abrasion resistant and/or electrically conductive gloves (10), or yarns which are as much as 85 to 90% by weight metallic fiber. When knit into gloves, added protection may be provided from puncture injuries if the palm (12), finger stalls (14) and thumb stall (16) are coated or impregnated with an elastomer or the like.
