    Abstract: A method of producing a fluid-pervious fabric for imparting a pattern to a fibre web, wherein said fabric (101; 201) is brought into a press nip (105) between a rotating embossing roll (106) having embossing means (107) on its outer surface and a support (108). Said fabric comprises at least two zones as seen in the z-direction, a first zone (101a;201a) and a second zone (101b,,201b), wherein said first zone comprises a first polymer material having a first glass transition temperature and said second zone comprises a second polymer material having a second glass transition temperature which is higher than that of said first polymer material.

  • Publication number: 20010053647
    Abstract: The invention concerns the manufacture of complex metallic or metallized porous structures, wherein the electroplating metal over the entire developed surface is preceded by a specific pre-metallization of the basic structure. The pre-metallization is obtained by depositing a conductive polymer, which is deposited on the entire developed surface of the structure by the steps of an oxidizing pre-treatment of the structure, depositing in the liquid phase, a monomer having a polymerized foam that is electrically conductive, and polymerizing oxidation-doping of the monomer. The structures according to the invention are particularly intended for use as electrodes for the electrolysis of liquid effluents, as electrode supports for electrochemical generators, as catalyst supports, filtration media, phonic insulation, electromagnetic and nuclear protection structures, or for other applications.

  • Patent number: 6309721
    Abstract: A sleeve having a longitudinally extending slit for covering wires or tubing is provided with a support layer of a continuous monofilament of formable metal wire or heat-settable monofilament formed into a multiplicity of spaced apart reversely bent crests and troughs. The continuous monofilament is bent to form a split tube having the crests and troughs in facing relationship. At least one outer layer is provided on said support layer. The outer layer may be an insulator such as a metal foil or metalized film, an abrasion-resistant material or a resilient sound-absorbing material. Inner layers may comprise insulating materials and/or felts, foams or other sound-absorbing materials. Various closure means for closing the longitudinal opening formed at the slit are disclosed.

  • Patent number: 6214456
    Abstract: A unique headliner includes a pair of spaced polyester fiber mat layers. The polyester fiber layers are preferably felt layers which are needled and consist of a mixture of low and high melt polyester fiber pieces. The low melt fiber pieces are provided with an adhesive sheathing that melts at a low temperature to bond the fiber pieces together. The polyester layers are spaced on opposed side of a polyurethane foam central layer. The combined headliner construction has good strength and acoustic characteristics.

  • Patent number: 6171686
    Abstract: A synthetic structure is used to simultaneously provide food, shelter and reproductive support for many aquatic species. Synthetic seagrass may be produced in the form of flexible mats with a plurality of ribbons. The lower ends of the ribbons are anchored to the benthos. The other ends of the ribbons are buoyantly supported in the photic zone. The ribbons may be economically produced in plural coextensive layers, with one layer providing buoyancy and the other layer being structured to enhance biological growth. The system may be tailored for use in desired applications by selecting the surface area structure, ribbon spacing and density, and other parameters. The system may be used to remove nutrients and/or toxic materials from water. The invention may be used to simultaneously promote aerobic and anaerobic reactions to control water quality.

  • Patent number: 6140260
    Abstract: A felt for use in a papermaking machine includes a woven base fabric and a batt layer for supporting the paper web. A flow control layer is interposed between the base fabric and the fibrous batt layer, to impede rewetting of the paper web as the paper web exits a press nip of the papermaking machine. The flow control layer is formed of a porous hydrophobic material. Pressure exerted by the press nip forces water from the paper web through the batt layer and the flow control layer into the base fabric. When the pressure is relieved, the hydrophobic properties of the flow control layer impede back-flow of water to the batt layer and thence to the paper web, thereby impeding rewetting of the web. The flow control layer is preferably formed of a spunbonded filamentary nylon material which is non-circular in cross-section, such as tri-lobed/triangular, and which may be treated with an hydrophobic chemical composition to enhance hydrophobic properties.

  • Patent number: 5952087
    Abstract: The object of the present invention is to improve the overall strength and interlaminar strength of a compact (green sheet) before hydrothermal reaction by using alunites, alums and aluminum sulfate having a specified specific surface area which does not require the addition of a setting retarder or a curing accelerator together with a curing agent in order to provide a method of manufacture for a lightweight calcium silicate board which does not give rise to interlaminar peeling or bursting during hydrothermal reaction and to provide such a calcium silicate board. The method of manufacture for a calcium silicate board according to the present invention is characterized by use of one or more species selected from alunites and alums with a Blaine specific surface area of 4000 cm.sup.2 /g or more or aluminum sulfate with a Blaine specific surface area of 2000 cm.sup.2 /g or more.

  • Patent number: 5945358
    Abstract: A papermaker's fabric is provided having a spun bonded reinforcement. A layer of spun bonded material may be placed in any one of a number of possible locations in the fabric, depending upon the felt stratification desired. For example, it may be attached to the upper surface (or paper contacting side) of the base fabric layer; to the lower surface (or machine contacting side) of the base fabric layer; between two base fabric layers, in the case of a laminated felt; between layers of fibers; or in any other desired location. The spun bonded material may be attached through the use of needling or by use of adhesives, low melts, or ultrasonic methods.

  • Patent number: 5891516
    Abstract: Fiber cement felts of the present invention include: a top fabric layer that includes fine machine direction yarns and fine cross machine direction yarns interwoven with the fine machine direction yarns; a bottom fabric layer underlying the top fabric layer that includes coarse machine direction yarns and coarse cross machine direction yarns interwoven with the coarse machine direction yarns; and a batt layer attached to and overlying the top fabric layer. Preferably, the top fabric layer is heat bonded to the bottom fabric layer. It is also preferred that the fiber cement felt of the present invention include a second batt layer that underlies the bottom fabric layer. In this multiple layer structure, the felt can have higher tenacity, improved resistance to blinding and compaction, and a reduced tendency to mark a fiber cement sheet during its formation.
