  • Publication number: 20140262478
    Abstract: A textile fabric, sleeve formed therefrom, and methods of construction thereof are provided. The fabric forms an elongate wall constructed from lengthwise extending warp yarns woven with widthwise extending weft yarns. At least some of the warp yarns are electrically conductive and have a first diameter. The weft yarns have a second diameter that is at least 25 percent less than the first diameter of the warp yarns. As such, the conductive warp yarns are brought into closer proximity with one another than if the weft yarns were the same diameter as the warp yarns. Accordingly, the ability of the fabric and sleeve formed therewith to provide shielding protection against EMI is enhanced.

  • Publication number: 20090126987
    Abstract: A braided shield includes a housing formed from a plurality of wires braided together and having a dual-layer configuration. The housing has an outer layer integrally formed with an inner layer. A support is at least partially disposed in the housing, and the inner layer is disposed between the support and the outer layer. The inner layer and outer layer reduce electromagnetic radiation leakage into/out of the housing by reducing the number of holes in the housing. Forming the braided shield includes providing the housing, which defines a longitudinal axis and a passage extending along the longitudinal axis. The housing has an end portion, and the end portion is compressed transverse to the longitudinal axis. The end portion is then forced into the passage. Accordingly, the braid shield reduces or eliminates electromagnetic radiation while providing a strong and consistent crimp with the support.
