  • Patent number: 7018946
    Abstract: The present invention is directed to a multi-filament yarn formed at least in part from filaments having cross-sectional zig-zag or double “W” shape with a 180 degree axis of symmetry. The filaments have a denier per filament generally in the range of about 0.1 to about 4.0. Fabrics made from yarns formed with the filaments have high moisture wicking, soft hand, and a silk-like lustrous appearance.
    Type: Grant
    Filed: July 1, 2004
    Date of Patent: March 28, 2006
    Assignee: Invista North America S.a.R.l.

  • Publication number: 20030187140
    Abstract: A synthetic polymer yarn comprising a bicomponent yarn and a second yarn combined to form a single yarn is disclosed. The bicomponent yarn is made up from a first component and a second component each comprised of a fiber-forming polymer and each having different shrinkages from the other to effectuate a bulking effect. This differential shrinkage may be obtained, for example, by using different polymers or similar polymers having different relative viscosities. The synthetic polymer yarn of the present invention has advantageously exhibited an improved visual effect, including a stratified effect, which improves the visual composition of products produced using the yarn. Moreover, the fabrics produced from the yarn have improved hand and stretch and recovery.

  • Publication number: 20020034903
    Abstract: The present invention is directed to a multifilament yarn formed at least in part from filaments having cross-sectional bilobal S-shapes or Z-shapes. The yarns preferably have a denier per filament in the range of about 0.1 to about 4.0. In addition, fabrics made using the yarns of the present invention are disclosed. The fabrics have high moisture wicking, soft hand, and a silk-like lustrous appearance.
