Felt Fabric Patents (Class 442/320)
  • Patent number: 5874136
    Abstract: Several headliner embodiments include a felt layer connected to a cover layer. In the preferred embodiments a pair of felt layers are positioned on both sides of a central mat layer. The mat layer provides loft, while the felt layers in combination with the mat layers provide other desired characteristics for the headliner.

  • Patent number: 5871887
    Abstract: The invention comprises an apparatus for use in making a web of papermaking fibers. The apparatus comprising: a dewatering felt layer having a first web facing felt surface at a first elevation and a second oppositely facing felt surface, and a web patterning layer comprising a photosensitive resin. The patterning layer penetrates the first felt surface, and extends from the first felt surface to form a web contacting top surface at a second elevation different from the first elevation. The invention also comprises a method of forming a web support apparatus having a felt layer and a web patterning layer.

  • Patent number: 5866215
    Abstract: A composite component is provided having at least one felt layer as reinforcement when used for crash and/or noise management applications, and preferably also including at least one reinforcement fiber layer. At least one of the reinforcement layers, preferably a felt layer, may be formed into a preform which is placed into a mold of suitable shape to form the component, along with the other reinforcement layers, with a resin/polymer being injected into the mold and then cured to form the composite component.

  • Patent number: 5834382
    Abstract: A covering which is resistant to high temperature and intended to be inserted between tools and plates of hot glass includes a knitted fabric formed from an assembly of stitch wales which gives at least one plane face. The knitted fabric is provided with openings, the polygonal shape of which is determined by a plurality of non-bound segments each including a portion of a stitch wale, and of bound segments formed by making more than four stitches common to two adjacent stitch wales. The making common is obtained by the mutual transfer of stitches from one wale to the other.

  • 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: 5804310
    Abstract: Patterned fibers having repeating segments of controlled conductivity separated by insulating segments are prepared by patterning the fiber with photoresist and, optionally, metallizing bare portions of the fiber where the photoresist has been exposed and removed. Fibers of the present invention can be patterned as alternating segments of bare fiber/photoresist-coated fiber, bare fiber/metallized fiber, or metallized fiber/photoresist-coated fiber.

  • Patent number: 5776841
    Abstract: This invention concerns a light weight sheet felt material suitable for use as roof and siding underlayment and insulation board facing which comprises on a dry basis(a) 60-80 wt. % cellulose fibers;(b) 15-30 wt. % glass fibers having a diameter of 5 to 16 microns and a length of 3/8-3/4 inch;(c) 4-10 wt. % binder and(d) 0.5-10 wt. % non-asphaltic, sizing agent having a flash point above 150.degree.F. and an evaporation rate less than one which is selected from the group consisting of anionic rosinous and amphipathic ester and anhydride sizes and mixtures thereof.The felt of this invention is of considerably lighter weight and higher porosity than other felting materials used for the same purpose and can be supplied in longer continuous sheet rolls than heretofore practical from a standpoint of handling, shipping, storage, and installation. Also the present sheet felt can be produced on conventional felt making equipment in a one step process.

  • Patent number: 5712210
    Abstract: A longitudinally extending web of lofty nonwoven abrasive surface treatment material is provided in a coreless roll form to the end user. Successive wraps of the nonwoven abrasive material have interengaging surfaces sufficient to maintain the material in a spirally wrapped configuration yet being readily separable. A plurality of longitudinally spaced and laterally disposed perforations through the web permit the user to successively separate the web into a plurality of sheets of abrasive surface treatment material. In a preferred embodiment, the roll is encased in a protective shrink wrap sheath, and each sheet is separated from the roll by separating said sheet from an innermost wrap of the roll.

  • Patent number: 5662507
    Abstract: The invention provides a heat-resistant felt for hot products which is sufficiently heat-resistant for conveying or placing hot products thereon in manufacturing processes of iron and steel, non-ferrous metal, and ceramics products, and contributes to the improvement of the quality and life of products. A heat-resistant fiber web of a blend or laminate comprising metal fibers and inorganic fibers or a heat-resistant fiber web of a blend or laminate comprising metal fibers or inorganic fibers and heat-resistant organic fibers is needle-punched with or without a heat-resistant ground fabric laminated so as to intermingle.
