  • Patent number: 8173255
    Abstract: One of the major problems of commercial clean flame retardant materials is unstable mechanical properties because of high filler loadings. Clean flame retardant compositions having very low smoke and toxicity generation are invented by a method based on partial cross-linking of polymers. These composites are processed by routine thermoplastic extruder and do not use post curing system. Composition mainly contain 100 parts by weight (p/w) of resin (polyolefin or 100 p/w of polyolefin/ethylene propylene diene monomer rubber (EPDM rubber)), 90-150 p/w of non halogen content main flame retardants, 0.1-0.5 parts by weight of crosslinking agent, 1-20 p/w of auxiliary secondary flame retardant agents and 0.2-1.0 p/w of antioxidants. Clean flame retardant compositions use peroxide composite as a crosslinking agent and metal hydroxide composite as a flame retardant.

  • Patent number: 8012891
    Abstract: A process for imparting flame resistance and the flame resistant fabrics produced by such process are provided. The process for imparting flame resistant properties involves treating a target fabric with one or more flame retardant chemicals (and, preferably, a softening agent) and then curing the treated fabric to durably affix the flame retardant to the fabric. In many cases, it may be desirable to subject the treated fabric to mechanical face finishing to increase softness. Optionally, stain release agents, soil repellent agents, permanent press resins, and the like may be added to the bath of flame retardant chemicals, eliminating the need for one or more additional manufacturing processes. Alternately, soil repellent agents may be applied to only one side of the treated fabric after the application of the flame retardant chemicals. The present fabrics exhibit improved performance and tear strength, even after repeated launderings, as compared to conventionally treated fabrics.

    Abstract: A kind of fireproof cloth includes a piece of polyacrylonitrile fiber cloth; to make the polyacrylonitrile fiber cloth, first polymer of polyacrylonitrile is spun into fiber, and flame-resisting treatment is carried out on the polyacrylonitrile fiber in air, and next the polyacrylonitrile fiber is woven into polyacrylonitrile fiber cloth; because of the flame-resisting treatment, the polyacrylonitrile fiber has high strength, high elasticity and heat isolation capability, and is highly resistible to instantaneous high temperature; the polyacrylonitrile fiber cloth has excellent water absorbing capability therefore structure of the fireproof cloth won't be damaged when the fireproof cloth is washed with water.

  • Patent number: 7785694
    Abstract: The invention relates to an arrangement for lining the interior of a passenger vehicle such as an airplane including a honeycomb formation of several honeycombs arranged side by side. At its end, the honeycomb body is supported by a cover layer supported above and below the honeycomb formation such that by means of two cover layers glued onto the honeycomb formation, a layer design of the honeycomb paneling is created, which layer design is arranged so as to extend parallel to the outer skin of the aircraft and follow the curvature of the outer skin. The honeycomb formation used is made of paper or aramide honeycombs or of a mixed combination of both honeycomb types; on whose cross section of the honeycomb body a CFK cover layer is positioned to both ends of the honeycomb bodies. As an alternative, further CFK insulation layers are glued onto the outer surface of the respective cover layer supported above and below the honeycomb formation, which cover layers comprise a CFK or GFK.

  • Patent number: 7776421
    Abstract: A composite velour fabric garment includes a laminate consisting of an outer woven shell layer, an inner thermal layer of knit construction, and an intermediate layer disposed between and laminated to each of the shell layer and the thermal layer. The outer woven shell layer contains spandex in at least a weft direction for stretch and recovery in a width direction. The knit construction of the inner thermal layer provides stretch in at least a width direction, in harmony with the shell layer, and the inner thermal layer has a raised surface facing inwardly, away from the shell layer. The intermediate layer has controlled air permeability, including zero air permeability.

  • Patent number: 7754332
    Abstract: Thermal insulation structure having at least one flexible layer based on compressed expanded graphite particles characterized in that the density of the said flexible layer is equal to at least 0.4 g/cm3 (400 kg/m3) and in that the thermal insulation structure also includes another layer close to the flexible layer based on compressed graphite particles with a lower density, typically less than 0.4 g/cm3 (400 kg/m3). Preferably, the dense compressed expanded graphite layer has a density of between 0.5 and 1.6 g/cm3 (500 and 1600 kg/m3) and the sub-dense compressed expanded graphite layer has a density of between 0.05 and 0.3 g/cm3 (50 and 300 kg/m3). Thermal insulation elements are also described that are designed to be fitted on furnaces operating under non-oxidizing atmosphere and at temperatures of more than 800° C.

  • Patent number: 7717187
    Abstract: A self-protecting barrier for retarding fire has a combustible hydric member or a network of combustible hydric members having an ignition temperature above 100° C., at least a first surface which is water-permeable and may be flammable, and a sufficient water absorption capacity for fire retardation. The hydric members may be foamed-polymer elements, or superabsorbent polymer-filled matrixes, or loose superabsorbent polymer-filled pouches or pockets. A self-protecting barrier system for retarding fire further includes fire adjacent the water-permeable surface and steam between the water-permeable surface and the fire, and may further include a combustible object adjacent the barrier opposite the fire. A method of isolating a combustible object from the flames of a fire includes the steps of providing at least one fire-retardant barrier between the object and the flames, volatilizing or boiling a portion of the hydration water at a temperature of about 100° C.

  • Patent number: RE41574
    Abstract: A velour fabric article consists of a fabric body having a technical face formed by a filament stitch yarn and a technical back formed by a loop yarn. The filament stitch yarn includes a heat sensitive material, e.g. a hot melt material or a heat shrinkable material, and/or an elastomeric material, such as spandex. The loop yarn includes flame retardant material, such as M-Aramide fiber. The fabric body has a velour surface formed at one or both of the technical back and the technical face. Raised fibers of at least one of the technical face and the technical back may be entangled, including in and/or through interstices of the fabric body, toward the other of the technical face and the technical back, e.g., by a hydroentanglement process applied after finishing. The fabric body has permeability of about 90 ft3/ft2/min, or less, under a pressure difference of ½ inch of water across the fabric body.
