A first thin layer in contact with the floor comprises virgin fibers, a second thick layer in contact with the bottom of the leg of a piece of furniture comprises recycled material fibers. Both layers are joined together by means of a fusion which forms a thin intermediate layer formed by the fusion of virgin fibers with recycled material fibers, thereby making both layers inseparable one from the other. The use of recycled fibers in bigger quantity than the virgin fibers allows giving a second life to fibers having already served a first time.

    Abstract: A sealant is arranged in a meshlike manner between a composite layer and a barrier layer in a water-tight membrane that includes a barrier layer and a composite layer. In the case of a leak in the barrier layer, the network of sealant between the composite layer and the barrier layer prevents the barrier layer from being affected. As a result, the size of the areas affected by penetrating water is limited. The damage by the penetrating water is thus limited to a smaller area, and the point of damage can thus be more easily localized.

  • Patent number: 6936329
    Abstract: A fastener-free composite roofing product comprising a roofing material and an interply material attached to the roofing material, wherein the interply material includes an adhesive coating on one side. The interply material is attached adjacent to an edge of the roofing material to permit a major portion of the interply material to be folded away from the roofing material for application to a roof. The adhesive is effective to secure the roofing product to the roof without the use of nails or other fasteners. The roofing material may be a roofing shingle or roll roofing, and the interply material is comprised of a water resistant material.

  • Patent number: 6914022
    Abstract: A lightweight, flexible, layered insulation composed of glass or ceramic fabric covered with a ceramic coating and overlying an insulating felt made from needled polybenzazole (PBZ) material which is preferably polybenzoxazole (PBO), and which optionally contains a poly(1,3-phenylene isophtalamide) felt material, commercially known as Nomex™, either combined with the PBZ felt or layered beneath the PBZ felt as a separate layer. The insulation is readily applied to a reusable launch vehicle via a silicone adhesive.

  • Patent number: 6846759
    Abstract: A method of making a soft, well cushioned, fabric suitable for use in an automotive interior, furniture and upholstery. The fabric which is formed by depositing a coating of a high temperature adhesive having a viscosity of 6×104 to 75×104 centipoise at its application temperature on one surface of a felt cloth followed by laying down a layer of a second material on top of the adhesive-coated surface of the felt cloth to form a composite. The composite is then passed through a hot pinch point to firmly bond the second layer to the felt cloth.

  • Patent number: 6846545
    Abstract: A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.

  • Publication number: 20040219846
    Abstract: A composite sheet biasable into a tubular shape to form a sleeve for isolating or protecting elongated items is disclosed. The sheet has a reflective surface formed by a metal foil layer overlying a flexible polymer layer having a metalized surface. A biasable polymer netting layer is positioned overlying the flexible layer opposite the metalized surface. The netting layer is formed of elongated members that define interstices. A damping layer of non-woven material is positioned adjacent to the netting layer. An adhesive layer is positioned between the flexible layer and the netting layer to bond the netting layer and the damping layer to the flexible layer. Biasing is effected by the elongated members of the netting layer which are stiffer in the circumferential direction around the sleeve to provide radial stiffness.

  • Publication number: 20040200594
    Abstract: Papermaking felt containing a hydrophilic urethane resin that can maintain functions such as water drainage, wet-paper smoothness, and wet-paper transportability by imparting a hydrophilic property to the papermaking felt thereby preventing the deposition and accumulation of adhesive contaminants without impairing the compression recoverability of the felt thus sustaining its antifouling capability.
