  • Patent number: 8273201
    Abstract: A fiber mixture of natural fibers and binder fibers are blown from a storage container onto a first transport belt with a three-dimensional alignment of the fibers resulting in a fiber fleece. Thermally activatable synthetic resin granules are blown onto the fiber fleece and the fleece is defibered and remixed. The remixed fiber mixture is blown onto a second transport belt with a three-dimensional alignment of the fibers resulting in a mat. The thickness of the mat is obtained by the circulating speed of the second transport belt. The mat is transferred to an oven belt and is moved through a heating/cooling oven, for softening of the binder fibers and the synthetic resin granules, resulting in an intimate bonding of the wood fibers, the binder fibers, and the synthetic resin granules. The final thickness and the bulk density are set to specified ranges.

    Abstract: A method for the manufacture of spatial objects of a fleece or felt, wherein the fibers are deposited on a mold that is preferably air-permeable. The fibers may be attracted to the mold by a vacuum applied to the underside of said mold. Preferably, the mold has several spatial structures that define the shape of the fiber web that is being formed and that correspond at least approximately to the desired final shape. By subsequent compacting of the thusly obtained fiber web, a spatially three-dimensional felt object is obtained. In this method, subsequent deforming steps are unnecessary or reduced to a minimum, so that the material to be produced does not experience any substantial distortion.

    Abstract: A unitary, fiber-containing composite comprises (a) a first region comprising a plurality of first binder fibers and a plurality of bast fibers, (b) a second region disposed above the first region, the second region comprising a plurality of second binder fibers and a plurality of bast fibers, and (c) a transitional region disposed between the first region and the second region. The transitional region comprises concentrations of the first binder fiber, the second binder fiber, and the bast fiber. The concentration of the first binder fiber in the first transitional region is greatest proximate to the first region and least proximate to the second region, and the concentration of the second binder fiber and the bast fiber in the first transitional region is greatest proximate to the second region and least proximate to the first region. A method for producing a unitary, fiber-containing composite is also described.

  • Patent number: 7914721
    Abstract: For producing a ceramic material, a mask having a predetermined shape is located on a substrate, and a spacing is formed between the substrate and the mask. An aerosol, which contains a carrier gas and raw material particles dispersed in the carrier gas, is jetted out onto the substrate, and the jetted-out aerosol is caused to flow into the spacing between the substrate and the mask. The raw material particles, which are contained in the aerosol, are deposited in the spacing between the substrate and the mask, and a molded body having the same shape as the shape of the mask is formed.

  • Patent number: 7745685
    Abstract: A technique for incorporating odor control agent particles into an absorbent article is provided. More specifically, the odor control particles are “homogenously” distributed (e.g., in a substantially uniform manner) within an airformed fiber matrix of an absorbent core of an absorbent article. An absorbent core containing such a homogeneously distributed odor control particles may possess a greater surface area for contacting malodorous compounds, thereby increasing the likelihood of odor reduction.

  • Publication number: 20100091202
    Abstract: A glass fibre reinforced plastic substrate provides the mechanical strength and thermal properties for use e.g. in flat display devices. There is a trend towards flat display devices comprising flexible displays. Such display devices also need flexible substrates, and a method to produce such flexible substrates cost effectively. To make such flexible display by conventional manufacturing technologies that have been applied to produce the LCD displays, glass substrates need to be replaced with elastic substrate materials that are deformable even at room temperatures. The elastic substrate must have mechanical durability to offer flexibility desired. Now there is developed a method for producing a glass fibre reinforced plastic substrate so that the glass fibres and binding material are arranged to form a layer with a certain content of glass fibres and then the layer is arranged to be pressed to a thickness that is desirable to the substrate sheet.

  • Patent number: RE42765
    Abstract: A plant serves as a mean for production of a fibre web of synthetic fibres, such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres. The plant includes a forming head preliminary to lay a homogeneously and smoothly distributed fibre layer on a net shaped wire. Furthermore the plant includes a hydro-entangling section with liquid nozzles with powerful liquid jets to treat the in the forming head formed fibre layer, which consists of both synthetic—and absorbent fibres. The plant also includes an oven subsequently to thermal bond the synthetic fibres with cross bonds in the affected areas. Finally the dried web is winded up in a roller. By the help of the plant according to the invention, by higher production speed than known previously a fibre web can be produced, which is far cheaper, and which has a better and more homogeneous structure than similar conventional fibre webs.
