  • Method of producing a nonwoven fabric from filaments
    Patent number: 7854816
    Abstract: A laminate is made by first treating two spun-bond webs formed of endless thermoplastic synthetic-resin filaments with wetting agents. Then a layer of hydrophilic fibers is applied to one of the treated spun-bond webs and then the other of the treated spun-bond webs is applied to the layer of hydrophilic fibers on the one treated spun-bond web. Finally the two treated spun-bond webs and the layer of hydrophilic fibers between them are hydrodynamically consolidated together.
    Type: Grant
    Filed: January 14, 2008
    Date of Patent: December 21, 2010
    Assignee: Reifenhauser GmbH & Co. Maschinenfabrik
    Inventors: Sebastian Sommer, Jens Güdden
  • Method of making a fiber laminate
    Patent number: 7611594
    Abstract: An absorbent wiping cloth can be made by hydraulic bonding of hydrophilic fibers with a prebonded spunbond filament layer. A further spunbond filament layer can be provided on the fiber side of this laminate.

  • Method of producing a nonwoven fabric from filaments
    Publication number: 20040154731
    Abstract: Spun bond is made by collecting thermoplastic filaments on a perforated surface and the spun bond is then subjected to hydrodynamic consolidation with high-pressure water jets. The filaments before the formation of the spun bond or after the formation of the spun bond are treated with a wetting agent prior to the hydrodynamic consolidation.
