  • Patent number: 11807994
    Abstract: In a first step, a molding die is immersed in a raw liquid including cellulosic fibers. Then, the liquid of a raw liquid is sucked through a net material by a liquid suction part, so as to cause the cellulosic fibers to be laminated on the net material. In the second step, the cellulosic fibers laminated on the net material are dried, so as to form a protrusion. In the third step, the dried protrusion and the communication part are removed from the molding die. A passage part of the communication part is formed at a position where a projection portion had been arranged, the passage part being configured to communicate an inside of the protrusion with an outside of the protrusion.

  • Patent number: 8728272
    Abstract: Although a microfibrillated cellulose has been conventionally added to a resin molded article for the purpose of improving the properties of resin such as strength, it is only possible to achieve the same level of strength as that of the resin itself. The object is to provide a resin molded article of greater strength. A molded article can be produced by blending resin with a microfibrillated cellulose having a type-II crystalline structure produced by treating a microfibrillated cellulose with an alkali solution. The molded article can be largely increased in tensile strength or flexural strength, tensile strain at break or flexural strain at break, and fracture toughness (work-of-fracture) compared to a molded article produced with resin containing a conventional microfibrillated cellulose.

  • Patent number: 8025769
    Abstract: This invention is an acoustic fiber-based substrate composed primarily of insulation-type spun fibers or blends of such fibers and wheel spun fibers. The fibers are bound with a water-dispersible latex binder, or an agri-binder such as starch in conjunction with cellulose fiber. The insulation-type spun fibers can be first quality virgin, post-industrial waste-stream or post-consumer waste stream fiber. The substrate is wet-formed from a very dilute aqueous dispersion of ingredients onto a mesh forming screen, as on a Fourdrinier paper machine. By virtue of the insulation-type spun fiber dimensions, morphology and orientation: very low density wet-mats can be formed from a sufficiently dilute suspension. With respect to other wet-formed substrates, the invention is much lower in density and more highly porous, and, thus, the substrate is highly absorbing, exhibiting noise reduction coefficients, NRC values of about 0.80 or greater.

    Abstract: Methods for making a molded beverage container insulator from a slurry including water and a polysaccharide by presenting at least one male mold, which may have an elliptical cross section, therein and causing a portion of the slurry to temporarily adhere to the at least one mold. After a suitable period of time, removing the mold from the slurry and then removing the insulator. At such time, and particularly if the mold is not characterized as elliptical in cross section, the insulator is subject to bidirectional compression in order to collapse the same. Opposing hinge elements may be formed in the insulator, either at the time of molding or subsequently, to localize stresses resulting from the collapsing of the insulator. The resulting insulator is fully recyclable/compostable and possesses a constricting bias to mitigate container slip issues.

    Abstract: A molding head is especially adapted for vacuum molding or forming of structures and, in particular, fibrous composite structures in an adjustable, controllable three dimensional orientation before, during and after molding. Such a molding head includes a mold plate with narrow slots in the mold surface thereof and wider channels in the back surface thereof, with such slots and channels intersecting one another. A control system of servomotors or other actuators permits movement and orientation of the mold head during forming, thereby creating the ability to vary the material properties based on gravity and particle or suspension grain, thickness and other now controllable properties.

  • Publication number: 20100038047
    Abstract: A method of making a formed, dried lignocellulose fiber material comprising (a) providing an aqueous lignocellulose fiber pulp slurry having an effective consistency; (b) de-watering the slurry to provide a de-watered material at an effective de-watering rate under an effective pressure to prevent or reduce the formation of fissures and voids within the material; (c) drying an effective amount of the de-watered material at an effective temperature and period of time to provide the formed, dried lignocellulose fiber material having a thickness of at least 5 mm. The formed, dried lignocellulose material may be used to make a lignocellulose fiber-resin composite material of use as a cost effective structural member, as a substitute for steel, in, for example, bridges, processing equipment, and the like.

  • Publication number: 20090314442
    Abstract: The present invention relates to a process for the manufacture of structural hybrid thermoplastic composites where organic and inorganic fibres are well dispersed in a thermoplastic matrix. The process comprises defibrillating the organic fibres with or without the presence of surface active agents using a mixer at a high shear and at a temperature lower than the decomposition temperature of organic fibres and melting point of the surface active agents to separate the hydrogen bonded fibres and generate microfibres, followed by blending and dispersion of the organic fibres in the thermoplastic matrix to produce a fibre composite, followed by further blending and dispersion of the fibre composite with inorganic fibres at a low shear to get the moldable hybrid composite, followed by extrusion, injection or compression-injection molding. Low shear mixing maintains the inorganic fibre length.

  • Patent number: 7591927
    Abstract: A method for manufacturing a wastepaper shock absorbing material using a vacuum forming principle is provided. The method includes disintegrating wastepaper selected from at least one of old corrugated containers, old newspapers and milk cartons, diluting the disintegrated wastepaper to form a pulp suspension, mixing the pulp suspension with a cationic starch to form a mixture, and vacuuming the mixture by applying a first vacuum in a first direction and a second vacuum in a second direction in a vacuum former to vacuum-dehydrate the mixture and provide a shock absorbing material. The first direction is substantially opposite to the second direction. The method further includes drying the shock absorbing material and performing a surface sizing process on a surface of the shock absorbing material. The wastepaper shock absorbing material has a low elastic modulus and density and can be manufactured without using the conventional press process performed by a press plate.

  • Patent number: 7582191
    Abstract: In a process for producing a loudspeaker diaphragm, pulp is deposited on a paper-making mold in the presence of vortex stream of water having pulp dispersed therein in a paper-making bath. Pulp is deposited on the paper-making mold while at least the water having pulp dispersed therein is rotated by the vortex stream in the paper-making bath. Consequently, variation of pulp fiber orientation is suppressed, and a loudspeaker diaphragm with high reproducibility and stable quality is produced with a high productivity.

    Abstract: This invention relates to a porous pulp mould comprising sintered particles and a plurality of drainage channels. The pulp mould of the invention can be produced in a fast and cost effective way. The moulding surface of the invention comprises small pore openings, to evacuate fluid and prevent fibres from entering the pulp mould. Furthermore the pulp mould of the invention comprises drainage channels improving the drainage capabilities of the pulp mould. The moulding surface can be heated to at least 200° C., due to high heat conductivity of the pulp mould and its ability to withstand high temperatures.
