  • Felt having conductivity gradient
    Patent number: 6346491
    Abstract: The present invention relates to an electromagnetically conductive textile fabric comprising conductive fibers arranged to provide a conductivity gradient through its thickness. The fibers may be intrinsically conductive or coated with a conducting material and the gradient can be related to variances in fiber density, fiber diameter (fineness) and fiber conductivity. The fabric can be used to eliminate or reduce electromagnetic interference (EMI) in various applications.
