  • Electromagnetic wave shielding material
    Patent number: 7238632
    Abstract: The present invention provides an electromagnetic wave shielding material including a three dimensionally knitted base material and a conductive metal layer formed on the three dimensionally knitted base material, which shielding material is characterized in that it comprises: a heat-fusing thread used at at least a portion of the three dimensionally knitted base material; and a portion in which connection thread is not present, wherein the amount of cutting debris generated at the time of cutting is decreased. According to the present invention, an electromagnetic wave shielding material, which is used for an electromagnetic wave shielding gasket for shielding electromagnetic wave, exhibits good workability if the thickness of the product is relatively thin, suppresses the metal separation and reduces the amount of cutting debris generated at the time of cutting, is obtained.
    Type: Grant

  • Electrically conductive fabric
    Patent number: 6787488
    Abstract: An electrically conductive fabric plated with a metal is disclosed wherein a percent fabric surface occupancy of warp as a constituent of the fabric is 90% to 110% and that of weft is 40% to 80%. The electrically conductive fabric is superior in all of resin back leak preventing property, flexibility yarn fray preventing property, electrical conductivity and electromagnetic wave shieldability.
