  • Spinning method
    Patent number: 8182915
    Abstract: A method is provided for spinning a multifilament thread from a thermoplastic material, including the steps of extruding the melted material through a spinneret with a plurality of spinneret holes into a filament bundle with a plurality of filaments, winding the filaments as thread after solidifying, and cooling the filament bundle beneath the spinneret, whereby in a first cooling zone the gaseous cooling medium is directed in such a way that it flows through the filament bundle transversely, the cooling medium leaving the filament bundle practically completely on the side opposite the inflow side, and in a second cooling zone beneath the first cooling zone, the filament bundle being cooled further essentially through self-suction of the gaseous cooling medium surrounding the filament bundle.
    Type: Grant

    Date of Patent: May 22, 2012
    Assignee: Diolen Industrial Fibers B.V.

  • Spinning method
    Publication number: 20050147814
    Abstract: A method is provided for spinning a multifilament thread from a thermoplastic material, comprising the steps of extruding the melted material through a spinneret with a plurality of spinneret holes into a filament bundle with a plurality of filaments, winding the filaments as thread after solidifying, and cooling the filament bundle in two steps beneath the spinneret, whereby in a first cooling zone the gaseous cooling medium is directed in such a way that it flows through the filament bundle transversely the method being characterized in that the cooling medium leaves the filament bundle practically completely on the side opposite the inflow side, and in a second cooling zone beneath the first cooling zone the filament bundle being cooled further essentially through self-suction of the gaseous cooling medium surrounding the filament bundle.
