  • Patent number: 5837623
    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.

  • Patent number: 5833788
    Abstract: SBR and natural rubber articles which can be marked with indicia are formed by curing the SBR or natural rubber under heat and pressure in contact with a fabric material. The curing conditions force the fabric into the cured rubber article. The fabric can then be marked with a heat-activated, indicia-bearing transfer. This provides for unique decoration of articles such as mud flaps and the like, and also permits providing identification for other rubber articles such as tires and the like.

  • Patent number: 5817408
    Abstract: The invention relates to a sound insulating structure including low-density and high-density layers. The low-density layer has first and second fibrous layers and ranges from 0.5 to 1.5 kg/m.sup.2 in surface density. The first and second fibrous layers are respectively made of first and second thermoplastic synthetic fibers. The first and second fibers respectively have first and second single fiber diameters, each of which diameters is in a range of from 3 to 40 .mu.m, and first and second fiber lengths, each of which lengths is in a range of from 10 to 100 mm. The high-density layer is formed on the low-density layer and is made of an air-impermeable polymer material and has a surface density that is higher than that of the low-density layer and ranges from 1 to 10 kg/m.sup.2. The low-density layer is high in sound-absorption coefficient and at the same time low in spring constant. Therefore, the sound insulating structure becomes substantially improved in sound insulating capability.

  • Patent number: 5817387
    Abstract: A modularized, encapsulated insulation assembly includes a plurality of insulation modules which each include a compressible, resilient insulation material encapsulated within a vented, flexible envelope which overlays and encloses the major surfaces, lateral surfaces, and at least the end surfaces of the insulation material at the ends of insulation modules facing other modules of the assembly. Where both ends of the insulation material in an insulation module are enclosed within the envelope, the envelope is vented to permit air to pass through the envelope during the compression and recovery of the insulation module. Each adjacent pair of insulation modules is joined by a flexible connector strip which extends between adjacent ends of the insulation modules and lies either substantially in the plane of one of the major surfaces or about midway between the major surfaces of the insulation modules.
