  • Publication number: 20020119299
    Abstract: A process for manufacturing wet-felted and thermally bonded porous structures is provided to produce formed porous media for use in filters with improved filtration performance. The process includes the steps of forming a slurry with a primary media consisting of natural or synthetic fibers, a wet strength agent consisting of fibrillated fibers, and a binding agent; vacuum forming the slurry to produce a formed media; drying the formed media using a gas at a temperature below the melting temperature of the binding agent; bonding the formed media using a gas at a temperature above the melting temperature of the binding agent; and cooling the formed media using a gas at ambient temperature. The process produces a formed porous media with improved bonding which results in improved filtration performance.

  • Publication number: 20020102896
    Abstract: Disclosed is a thermoplastic felt structure for an automobile interior substrate, comprising a pair of mat units, each mat unit having a felt layer which is made by a mixture of a jute fiber and a PP fiber mixed in the weight ratio of about 5 to 5˜6 to 4 and a PP foaming fiber adhered to one side of the felt layer, said mat units being coupled each other on the other sides of the felt layers. With this configuration, a thermoplastic felt structure for an automobile interior substrate can prevent a deflection thereof, and have high strength and stiffness, heat-resistance and impact-resistance. Further, the present thermoplastic felt structure can decrease the cost of raw material, enhance the fuel efficiency with a lightweight body, and accomplish a simple manufacturing process.

  • Patent number: 6103645
    Abstract: A method is provided to prepare a filter material, the method comprising the steps of: providing a porous substrate; preparing a high internal phase emulsion wherein the external phase of the emulsion comprises polymerizable monomers, and the internal phase is a non-polymerizable phase; impregnating the high internal phase emulsion into the substrate felt; and polymerizing the polymerizable monomers. A layer of cured foam as is thereby formed on the substrate and within pore volumes of the substrate. The cured foam can have a high porosity, small pore size, and low density, resulting in a filter material having a high efficiency in removal of particles, at a lower pressure drop than alternative high efficiency filter materials.
