  • Rigid fiber network structures having improved post-yield dimensional recovery, method of making same, and articles incorporating same
    Patent number: 6403196
    Abstract: A rigid three-dimensionally shaped fiber network structure having improved post-yield dimensional recovery is provided. The fiber network structure is formed from a fabric containing (A) at least one oriented, semi-crystalline monofilament yarn made from a first thermoplastic polymer, and (B) a second thermoplastic polymer which effects bonding of the monofilament cross-over points. The fiber network structures are useful in a variety of articles, including sandwich panels, various spacers, drainage systems, and energy absorption structures.

  • Shoes comprising three-dimensional formed fiber product
    Patent number: 5896680
    Abstract: Shoes for use in demanding applications, primarily athletics, are made from a three-dimensional fiber network that is semi-rigid and resilient. The fiber network is made from a textile fabric that has an array of projections made from the same fabric rising from the plane of the fabric.

  • Medical casts and other orthopedic devices comprising thermoplastic three-dimensional fiber networks
    Patent number: 5882322
    Abstract: Cast padding materials and padding and lining materials for other orthopedic devices are made from three dimensional fiber networks which are semi-rigid and dimensionally stable. The fiber networks are made from textile fabrics that have projections and optional depressions which are compressible and return to their original shape after being compressed. The fiber networks are made by the thermo-mechanical deformation of textile fabrics that are in turn made from thermoplastic fibers.
