  • Patent number: 5500295
    Abstract: Fiberballs have been prepared from mechanically-crimped fibers having both a primary crimp and a secondary crimp with specific configurations, especially amplitudes and frequencies. The fiberballs may contain a proportion of other fibers, particularly binder fibers, and used for making molded structures.
    Type: Grant
    Filed: July 19, 1994
    Date of Patent: March 19, 1996
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Walter B. Halm, William J. Jones, Jr., James F. Kirkbride, Ilan Marcus, Adrian C. Snyder
  • Patent number: 5480710
    Abstract: Fiberballs based on poly(1,4-cyclohexanedimethylene terephthalate) fiber have given improved products.
    Type: Grant
    Filed: March 17, 1995
    Date of Patent: January 2, 1996
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Michael S. Frankosky, Adrian C. Snyder
  • Patent number: 5344707
    Abstract: Fiberballs for filling uses in pillows, cushions and for like support purposes, from blends of slickened fiberfill of regular denier, to provide support and resilience, mixed with minor amounts of lower denier slickened fibers to provide optimum aesthetics.

  • Patent number: 5218740
    Abstract: Ball-shaped and other rounded fiber clusters that have a density that may be controlled, as desired, with good uniformity of size and density, may be obtained from staple fiber that has been crimped mechanically, as well as from spirally crimped polyester staple fiber, by an new process and apparatus at a high throughput. The process including feeding a uniform layer of staple fiber onto a peripheral surface of a rotating main cylinder covered with card clothing and rolling the fiber into rounded clusters.
