Fabric and clothes using the same

Abstract

A fabric comprises conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein at least either one of the conductive yarns in the warp direction or the weft direction is inserted as a double weave to be a float yarn on the surface that the conductive yarn becomes a float yarn in the double weave, wherein a ratio of the conductive yarn inserted as the double weave not covered by an orthogonal nonconductive yarn but exposed is not less than 50% in arithmetic average, and a ratio of the conductive yarns in the warp direction and the weft direction intersect and contact each other is not less than 40% in arithmetic average. Clothes comprise the fabric, wherein the conductive yarn is inserted as the double weave in an obverse side of the clothes.

1 ) A fabric comprising conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein at least either one of the conductive yarns in the warp direction or the weft direction is inserted as a double weave to be a float yarn on the surface that the conductive yarn becomes a float yarn in the double weave, wherein a ratio of the conductive yarn inserted as the double weave not covered by an orthogonal nonconductive yarn but exposed is not less than 50% in arithmetic average, and a ratio that the conductive yarns in the warp direction and the weft direction intersect and contact each other is not less than 40% in arithmetic average. 
     
     
         2 ) The fabric of  claim 1  further comprising a base weave having a nonconductive yarn, wherein a total yarn fineness D 1  of the conductive yarn inserted as the double weave and a total yarn fineness D 2  of the nonconductive yarn forming the base weave in the same direction satisfy the following relationship:
   D1<D2.   
     
     
         3 ) The fabric of  claim 1 , wherein the conductive yarns disposed in a lattice at intervals have a pitch in a range of 1 to 20 mm both in the warp direction and the weft direction. 
     
     
         4 ) The fabric of  claim 1 , further comprising a surface electric resistance (R) between two points separated by 30 cm across at least one seam that satisfies the following formula:
     R≦ 1.0×10 12 Ω.   
     
     
         5 ) The fabric of  claim 1 , wherein the conductive yarn comprises a monofilament having a circular cross section or an irregular cross section having a convex part, wherein a conductive component is exposed in at least 3 places in a circumferential direction of an outer circumferential surface and continuously in a longitudinal direction. 
     
     
         6 ) Clothes comprised of the fabric described in  claim 1 , wherein the conductive yarn is inserted as the double weave in an obverse side of the clothes.
