  • NON-ROUND SPINNERET PLATE HOLE
    Publication number: 20100084783
    Abstract: The present invention concerns a spinneret plate for manufacturing a nonwoven fabric, having multiple non-round holes, which are similar to trilobal or multiarmed holes in particular, for polymer flow outlet to produce filaments, in which identical holes are positioned in rows offset relative to one another. At least a first row has a positional arrangement of the holes that differs from the positional arrangement of a second row of rows through rotation of the holes.

  • Spunbond Fleece of Polymer Fibers and Its Use
    Publication number: 20080032579
    Abstract: The invention relates to a spun-bonded non-woven made of polymer fibers. These polymer fibers have a non-circular cross-section and a low fiber count. The polymer fibers have predominant directions in the spun-bonded non-woven. The spun-bonded non-woven has a high optical and/or physical opacity while having a low mass per unit area.
