Conductive fabric

Abstract

A conductive fabric in which variation in conductivity is suppressed is provided. A conductive fabric including a substrate formed by braiding or weaving a yarn, said substrate being coated with a metal, wherein the substrate has a substantially non-extending tissue and an opening formed in said tissue, and wherein the substrate is configured to extend by deformation of the opening when said substrate is pulled.

What is claimed is: 
     
         1 . A conductive fabric comprising a substrate formed by braiding or weaving a yarn, said substrate being coated with a metal, wherein:
 the substrate has a substantially non-extending tissue and an opening formed in said tissue, and   wherein the substrate is configured to extend by deformation of the opening when said substrate is pulled.   
     
     
         2 . The conductive fabric according to  claim 1 , wherein the substrate has an opening rate of 40-95% when not extended. 
     
     
         3 . The conductive fabric according to  claim 1 , wherein an extension ratio of a side of the opening of the substantially non-extending tissue at 20% extension relative to the substrate when not extended is set to from 0.90 to 1.10. 
     
     
         4 . The conductive fabric according to  claim 1 , wherein a tension at 20% extension in at least one or more of a longitudinal direction, a latitudinal direction and an oblique direction of the substrate is 10 N/cm or less. 
     
     
         5 . The conductive fabric according to  claim 1 , wherein an elongation rate, which is a ratio of a length when the substrate is pulled so that a resistance value with respect to a length of the substrate when not extended varies by 50%, is 15% or more in all of the longitudinal direction, the latitudinal direction and the oblique direction. 
     
     
         6 . The conductive fabric according to  claim 1 , wherein the substrate has a surface resistivity (Rs) when not extended of 10Ω/□ or less in all of the longitudinal direction, the latitudinal direction and the oblique direction. 
     
     
         7 . The conductive fabric according to  claim 1 , wherein the opening has a minimum inner diameter when not extended or contracted of from 0.5 to 5 mm. 
     
     
         8 . The conductive fabric according to  claim 1 , wherein the substrate is a tulle mesh knit or a marquisette knit in which a portion of the yarn forms a loop and another portion of the yarn is inserted into the loop. 
     
     
         9 . The conductive fabric according to  claim 1 , which is used as a sensor material, a monitoring material, a shielding material or an electrode material.
