William Rusty Wheat has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Fibers and Nonwovens with improved mechanical and bonding properties
    Patent number: 9994973
    Abstract: The present invention relates to fibers, particularly to as-spun fibers, having improved properties, in particular improved bonding performance and mechanical properties. In particular, the present invention relates to fibers comprising a metallocene random copolymer of propylene and one or more comonomers, said metallocene random copolymer having a broader molecular weight distribution. The present invention further relates to nonwovens comprising such fibers and to a process for producing such fibers and nonwovens. The fibers and the nonwovens of the present invention are characterized by improved properties, in particular improved bonding performance and mechanical properties, when compared to the prior art fibers and nonwovens.
    Type: Grant

  • Fibers and Nonwovens with Improved Mechanical Properties
    Publication number: 20110081817
    Abstract: The present invention relates to fibers, particularly to as-spun fibers, having improved properties, in particular improved mechanical properties. In particular, the present invention relates to fibers comprising a metallocene polypropylene having a broader molecular weight distribution. The present invention further relates to nonwovens comprising such fibers and to a process for producing such fibers and nonwovens. The fibers and the nonwoven of the present invention are characterized by improved properties, in particular improved mechanical properties, when compared to the prior art fibers and nonwovens.

    Publication number: 20110059668
    Abstract: The present invention relates to fibers, in particular to as-spun fibers, having an improved bonding performance. In particular, the present invention relates to as-spun fibers comprising a metallocene random copolymer of propylene and one or more comonomers. The present invention further relates to nonwovens comprising such fibers and to a process for producing such fibers and nonwovens. The fibers and nonwovens of the present invention are characterized by a wider bonding window as the prior art fibers and nonwovens.
