Electrically conductive and elastic textile band capable of transmitting electrical signal without distortion

Abstract

Disclosed is an electrically conductive and elastic textile band capable of transmitting an electrical signal by interconnecting wearable smart devices. The textile band can precisely transmit an electrical signal without distortion because there is almost no change in resistance according to extension although the textile band is extended in one direction.

We claim: 
     
         1 . An electrically conductive and elastic textile band in which a first direction fiber and the second direction fiber are orthogonal to each other, wherein the first direction fiber comprises an extensible yarn and a conductive yarn having electrical conduction, the extensible yarn and conductive yarn are orthogonal to the second direction fibers, respectively, the extensible yarn has a greater size of fiber than the conductive yarn, and the conductive yarn is positioned within a marginal space orthogonally formed by the second direction fiber. 
     
     
         2 . The textile band of  claim 1 , wherein the marginal space is formed between the extensible yarn arranged in the first direction. 
     
     
         3 . The textile band of  claim 2 , wherein the marginal space is formed by the extensible yarn protruded to a top and bottom of the second direction fiber. 
     
     
         4 . The textile band of  claim 2 , wherein the conductive yarn is extended in the first direction within the marginal space by a height difference formed by the conductive yarn before and after the extensible yarn. 
     
     
         5 . The textile band of  claim 1 , wherein a single or a plurality of the conductive yarns is alternately arranged along with one or more extensible yarns in the first direction. 
     
     
         6 . The textile band of  claim 1 , wherein a ratio of sizes of fiber of the conductive yarn and the extensible yarn is 1:4 to 1:8. 
     
     
         7 . The textile band of  claim 1 , wherein the electrically conductive textile band has a rate of change in resistance of 3% or less according to extension in the first direction. 
     
     
         8 . The textile band of  claim 6 , wherein the electrically conductive textile band has a rate of change in resistance of 3% or less if the electrically conductive textile band is extended 80% or less in the first direction.
