  • Patent number: 7883772
    Abstract: A fabric including microdenier fibers is provided, the microdenier fibers prepared by fibrillating a multicomponent, multilobal fiber including a contiguous core fiber component enwrapped by a multilobal sheath fiber component such that the sheath fiber component forms the entire outer surface of the multicomponent fiber, wherein the core fiber component and the multilobal sheath fiber component are sized such that the multicomponent, multilobal fiber can be fibrillated to expose the core fiber component and split the fiber into multiple microdenier fibers.
    Type: Grant
    Filed: June 28, 2007
    Date of Patent: February 8, 2011
    Assignee: North Carolina State University

  • Patent number: 7198473
    Abstract: An air compressor unit having an enclosure with a base. A motor is rigidly mounted to the base, and the motor drives both an airend and an impeller. The airend is pivotally mounted with respect to the base. The airend is directly connected to a horizontal separator tank, and the separator tank supports the airend. The airend and separator tank comprise a single integrated unit, and the separator tank is pivotally mounted to the base. The motor is a dual shafted motor having a drive side shaft and a non-drive shaft extending from opposite ends of the motor. A drive system is coupled to the drive side shaft and transfers power from the motor to the airend. The drive system is a belt and pulley system, and the airend is pivoted with respect to the motor to adjust belt tension. The impeller is coupled to the non-drive side shaft.

  • Publication number: 20060292355
    Abstract: The subject matter disclosed herein relates generally to fabrics composed of micro-denier fibers wherein said fibers are formed as bicomponent fibrillated fiber. The energy is sufficient for fibrillating as well as entangling (bonding) the fibers. These fabrics can be woven or knitted and made from made from bicomponent islands in the sea fibers and filaments or can be nonwovens and formed by either spunbonding or through the use of bicomponent staple fibers formed into a web by any one of several means and bonded similarly to those used for the spunbonded filament webs.

  • Publication number: 20060223405
    Abstract: A method of producing a nonwoven fabric comprising spinning a set of bicomponent fibers which include an external fiber component and an internal fiber component. The external fiber enwraps said internal fiber and has a higher elongation to break value than the internal fiber and a lower melting temperature than the internal fiber component. The set of bicomponent fibers are positioned onto a web and thermally bonded to produce a nonwoven fabric.
