  • Dual capillary spinneret for production of homofilament crimp fibers
    Patent number: 6446691
    Abstract: Robust homofilament fibers are meltspun from a differently shaped dual capillary spinneret design to induce differential fiber morphology to produce crimping. Crimping may further be aided by quenching and drawing of the fibers.
    Type: Grant
    Filed: December 21, 2000
    Date of Patent: September 10, 2002
    Assignee: Kimberly-Clark Worldwide, Inc.

  • Materials having z-direction fibers and folds and method for producing same
    Publication number: 20010054777
    Abstract: A method for producing a material having z-direction ridges or folds in which a layer of continuous fibers is conveyed on a first moving surface into a nip formed by the first moving surface and a second moving surface which is traveling at a slower speed than the first moving surface, resulting in formation of a plurality of z-direction loops in the fibers giving loft to the material and a wave pattern producing ridges on both major surfaces of the resultant nonwoven web. The method permits easy real time adjustment of manufacturing parameters to produce a variety of materials. The method further produces lofty nonwovens at a commercially viable rate.

  • High density nonwoven filter media
    Patent number: 6090731
    Abstract: The invention provides a sheet filter medium having autogenously bonded uncrimped conjugate fibers which contain a polyolefin and another thermoplastic polymer that have different melting points. The filter medium has a density between about 0.07 g/cm.sup.3 and about 0.2 g/cm.sup.3. The invention additionally provides a three-dimensionally thermoformed filter medium that has a density between about 0.07 g/cm.sup.3 and about 0.5 g/cm.sup.3.
