Industrial fabric

Abstract

An industrial fabric 10 includes: first warps; second warps; first wefts; and second wefts. The first warps and the second warps are provided while being shifted in a weft direction. The first wefts and the second wefts are provided while being shifted in a warp direction. The second wefts are located on the upper surface side of the industrial fabric. The first warps are woven only into the first wefts. The second warps are woven into the first wefts and the second wefts.

What is claimed is: 
     
         1 . An industrial fabric comprising: first warps; second warps; first wefts; and second wefts,
 wherein the first warps and the second warps are provided while being shifted in a weft direction,   wherein the first wefts and the second wefts are provided while being shifted in a warp direction,   wherein the second wefts are located on the upper surface side of the industrial fabric,   wherein the first warps are woven only into the first wefts,   wherein the second warps are woven into the first wefts and the second wefts,   wherein a pair of the first warps are adjacent to each other in the weft direction so as to form a first warp pair,   wherein a pair of the second warps are adjacent to each other in the weft direction so as to form a second warp pair,   wherein the first wefts and the second wefts are arranged alternately,   wherein the first warps have a weaving pattern of passing below all the second wefts and alternately going above and below the first wefts, and   wherein the second warps form a weaving pattern of passing above one of the first wefts, one of the second wefts, and one of the first wefts in order and then passing below one of the second wefts, one of the first wefts, one of the second wefts, one of the first wefts, and one of the second wefts in order.   
     
     
         2 . The industrial fabric according to  claim 1 , wherein the first warp pair and the second warp pair are arranged alternately in the weft direction. 
     
     
         3 . The industrial fabric according to  claim 1 , wherein the adjacent first warps constituting the first warp pair are woven into the first wefts while being shifted from each other by one first weft with respect to the first wefts in the warp direction. 
     
     
         4 . The industrial fabric according to  claim 1 , wherein a pair of the second warps constituting the second warp pair are woven into the second wefts while being shifted from each other by two second wefts with respect to the second wefts in the warp direction. 
     
     
         5 . The industrial fabric according to  claim 1 , wherein the total number of the first warps and the second warps is eight and the total number of the first wefts and the second wefts is eight in a weave repeat that forms a repeating pattern of the industrial fabric. 
     
     
         6 . The industrial fabric according to  claim 3 , wherein the weaving pattern of one of the first warps pairs and the weaving pattern of the other one of the first warp pairs are identical in a weave repeat that forms a repeating pattern of the industrial fabric. 
     
     
         7 . The industrial fabric according to  claim 1 , wherein the density of the first warps and the density of the second warps are in the range of 90 percent to 140 percent. 
     
     
         8 . The industrial fabric according to  claim 1 , wherein resin is applied to the upper surface of the industrial fabric. 
     
     
         9 . The industrial fabric according to  claim 1 , wherein at least some of warps constituting the first warps or the second warps are conductive carbon yarns. 
     
     
         10 . The industrial fabric according to  claim 1 , wherein the cross-sectional shape of the second wefts is elliptical or rectangular.
