Abstract

A conductive woven fabric consisting of multiple weft yarns and multiple warp yarns and having at least one conductive part, wherein one of weft and warp is consisting of non-conductive yarns and the other of weft and warp is consisting of conductive yarns and non-conductive yarns which are parallel to each other, characterized in that said non-conductive yarns parallel to the conductive yarns are shrinking-processed yarns and the conductive part is formed by a repeating woven structure wherein the conductive yarns pass through the upper side of at least two of non-conductive yarns orthogonal to the conductive yarns and then pass through the back side of at least one of non-conductive yarns orthogonal to the conductive yarns, and a process for producing the same, and also provides a conductive member using the same.

First claim

The invention claimed is:

1. A conductive woven fabric consisting of multiple weft yarns and multiple warp yarns and having at least one conductive part, wherein one of weft and warp is consisting of non-conductive yarns and the other of weft and warp is consisting of conductive yarns and non-conductive yarns which are parallel to each other, characterized in that said non-conductive yarns parallel to the conductive yarns are shrinking-processed yarns and said conductive part is formed by a repeating woven structure wherein said conductive yarns pass through the upper side of at least two of non-conductive yarns orthogonal to said conductive yarns and then pass through the back side of at least one of non-conductive yarns orthogonal to said conductive yarns.

2. The conductive woven fabric according to claim 1 , wherein the rate of the heat shrinkage percentage of the shrinking-processed yarns to the heat shrinkage percentage of the conductive yarns is within the range of 0.25 to 1.75.

3. The conductive woven fabric according to claim 1 , wherein said conductive part is formed by a repeating woven structure wherein said conductive yarns pass through the upper side of 2 to 7 of non-conductive yarns orthogonal to the conductive yarns and then pass through the back side of 2 to 7 of the non-conductive yarns orthogonal to the conductive yarns.

4. The conductive woven fabric according to claim 1 , wherein the weaving density of warp is within the range of 100/2.54 cm to 300/2.54 cm and the weaving density of weft is within the range of 100/2.54 cm to 300/2.54 cm.

5. The conductive woven fabric according to claim 1 , wherein the total fineness of said conductive yarns and non-conductive yarns is each within the range of 22 to 110 dtex.

6. The conductive woven fabric according to claim 1 , wherein the resistance value of said conductive yarns is 500 Ω/m or less.

7. A conductive member comprised of a conductive woven fabric according to claim 1 and a support, which has at least one linear bending part and exhibits conductivity over said linear bending part.

8. A process for producing a conductive woven fabric consisting of multiple weft yarns and multiple warp yarns and having at least one conductive part, which comprises a process of forming said conductive part by weaving, using non-conductive yarns as one of weft and warp and using conductive yarns and non-conductive shrinking-processed yarns as the other of weft and warp, by a repeating processing wherein said conductive yarns pass through the upper side of at least two of non-conductive yarns orthogonal to said conductive yarns and then pass through the back side of at least one of non-conductive yarns orthogonal to said conductive yarns.

9. The process for producing a conductive woven fabric according to claim 8 , wherein the rate of the heat shrinkage percentage of said shrinking-processed yarns to the heat shrinkage percentage of said conductive yarns is within the range of 0.25 to 1.75.
