Conductive cloth

Abstract

Provided is a conductive cloth having excellent stretchability and conduction stability. A conductive cloth 1a, 1b comprises a base cloth 10 and conductive yarns 100 stitched into the base cloth 10, wherein the constant load elongation ratio (S0) of the base cloth 10 is at least 24%, the conductive yarns 100 are stitched in at least two directions, and each conductive yarn 100 is exposed from at least one side of the base cloth 10, and the ratio (S1/S2) of the constant load elongation ratio (S1) of the conductive cloth 1a, 1b in a region in which the conductive yarns 100 are stitched and the constant load elongation ratio (S2) of the conductive cloth 1a, 1b in a region in which the conductive yarns are not stitched is 0.55 to 0.90.

What is claimed is: 
     
         1 . A conductive cloth comprising a base cloth and conductive yarns stitched into the base cloth, wherein
 the constant load elongation ratio (S0) of the base cloth as measured in accordance with the elongation ratio (D-method) of JIS L1096 in the presence of a load of 5 N applied thereto is at least 24%,   the conductive yarns are stitched in at least two directions, and each conductive yarn is exposed from at least one side of the base cloth, and   the ratio (S1/S2) of the constant load elongation ratio (S1) of the conductive cloth in a region in which the conductive yarns are stitched as measured in accordance with the elongation ratio (D-method) of JIS L1096 in the presence of a load of 5 N applied thereto, and the constant load elongation ratio (S2) of the conductive cloth in a region in which the conductive yarns are not stitched as measured in accordance with the elongation ratio (D-method) of JIS L1096 in the presence of a load of 5 N applied thereto, is 0.55 to 0.90.   
     
     
         2 . The conductive cloth according to  claim 1 , wherein
 the constant load elongation ratio (S3) of the entire conductive cloth as measured in accordance with the elongation ratio (D-method) of JIS L1096 in the presence of a load of 5 N applied thereto is at least 20%.   
     
     
         3 . The conductive cloth according to  claim 1 , wherein
 the conductive cloth has a resistance value change ratio during 40% elongation of at most 30%.   
     
     
         4 . The conductive cloth according to  claim 1 , wherein
 the base cloth has a thickness of at most 1 mm.   
     
     
         5 . The conductive cloth according to  claim 1 , wherein
 a space between each conductive yarn is 1 to 10 mm.
