  • Patent number: 11795621
    Abstract: A method for depositing, on a substrate, a composition of cellulosic fibers, includes preparing an aqueous suspension SA comprising at least cellulosic fibers, spraying, at a pressure no lower than 3 MPa, the aqueous suspension SA onto a substrate, wherein the spraying is carried out by means of a nozzle having a size between 0.05 mm and 3 mm, and obtaining a fibrous deposit DF on the substrate. The aqueous suspension SA includes at least 3% by weight of cellulosic fibers relative to the total weight of the aqueous suspension SA, and the aqueous suspension SA and the fibrous deposit DF have dry matter with identical composition.
    Type: Grant

    Date of Patent: October 24, 2023
    Assignee: KADANT LAMORT
    Inventors: Alain Lascar, Stéphan Pottier
  • Patent number: 11566377
    Abstract: A method for preparing a binder composition containing water, plant fibers and mineral fillers, wherein the method comprises: preparing a suspension of plant fibers and mineral fillers in water, the weight ratio between the plant fibers and the mineral fillers being comprised between 99/1 and 2/98, refining this suspension, and obtaining a binder composition wherein the refined fibers have a mean size of between 10 and 700 ?m, and wherein the refined fibers, at least partially, embed the refined mineral fillers, wherein refining is carried out in the absence of any grinding medium made of ceramic or metal.

  • Publication number: 20210108370
    Abstract: The present invention relates to a binder composition containing water, plant fibers and mineral fillers, the weight ratio between the plant fibers and the mineral fillers being comprised between 99/1 and 2/98, the plant fibers and the mineral fillers having been refined simultaneously, wherein the refined fibers have a mean size of between 10 and 700 ?m, and wherein the refined fibers at least partially embed the refined mineral fillers.
