Woven textile and protective sleeve for wire harness using the same

Abstract

A two- or more ply flat woven textile in which a texture A including a yarn A and a texture B including a yarn B are interwoven, wherein the yarn A and the yarn B are both a warp yarn or both a weft yarn, and shrinkage percentage of the yarn A (SA (%)) and shrinkage percentage of the yarn B (SB (%)) satisfies a specific range. The woven textile, when heat is applied, is spontaneously formed into a tube with a sufficient overlap in the circumferential direction. The tube provides easy insertion of lead wires and is able to protect the lead wires reliably without exposing the inserted lead wires.

1 . A two- or more ply flat woven textile in which a texture A comprising a yarn A and a texture B comprising a yarn B are interwoven,
 wherein said yarn A and said yarn B are both a warp yarn or both a weft yarn;   shrinkage percentage of said yarn A (SA (%)) and shrinkage percentage of said yarn B (SB (%)) satisfy (1); and   said woven textile, when heat is applied thereto, is formed into a tube such that a longer direction of said yarn A and said yarn B is a circumferential direction and said texture A is located outside said texture B:

         4 . The woven textile according to  claim 1 , wherein among fibers used for the warp yarn or the weft yarn of the woven textile, a melting point of the fiber with a lowest melting point TC (° C.) and a melting point of the fiber with a second lowest melting point TD (° C.) satisfy (2):
   40° C.<( TD−TC )<150° C.   (2),
 
 
     
     
         5 . The woven textile according to  claim 1 , wherein a polyphenylene sulfide fiber and/or a meta-aramid fiber are further interwoven in addition to said yarn A and said yarn B. 
     
     
         6 . The woven textile according to  claim 1 , which is a protective sleeve for a wire harness. 
     
     
         7 . A process of producing a tubular woven textile comprising applying heat to the woven textile according to  claim 1  so that said woven textile spontaneously rolls up due to a difference in shrinkage percentage between said yarn A and said yarn B to form a tube;
 the longer direction of said yarn A and said yarn B is the circumferential direction of the tube; 
 said texture A is located outside said texture B; and 
 one end and an opposite end of said woven textile separably overlap each other on the circumference of the tube, wherein the length of the overlapping portion in the circumferential direction is 2% or more of the circumferential length. 
 
     
     
         8 . The process according to  claim 7 , wherein said tubular woven textile is a protective sleeve for a wire harness. 
     
     
         9 . A tubular woven textile formed such that a flat two-ply woven textile in which a front surface texture and a back surface texture are interwoven is rolled up such that the front surface texture is located outside,
 wherein one end and an opposite end of said two-ply woven textile separably overlap each other on the circumference of the tube; and   in said tubular state, a circumferential length of a yarn arranged in said front surface texture (LA) and a circumferential length of a yarn arranged in said back surface texture (LB) satisfy (3):
   10%<{( LA−LB )/ LA}× 100 <60%   (3).
 
   
     
     
         10 . A protective sleeve for a wire harness comprising the tubular woven textile according to  claim 9 . 
     
     
         11 . The woven textile according to  claim 2 , wherein said yarn A comprises continuous fibers with a single-yarn fiber diameter 10 to 1000 μm. 
     
     
         12 . The woven textile according to  claim 2 , wherein among fibers used for the warp yarn or the weft yarn of the woven textile, a melting point of the fiber with a lowest melting point TC (° C.) and a melting point of the fiber with a second lowest melting point TD (° C.) satisfy (2):
   40° C.<( TD−TC )<150° C.   (2).
 
 
     
     
         13 . The woven textile according to  claim 3 , wherein among fibers used for the warp yarn or the weft yarn of the woven textile, a melting point of the fiber with a lowest melting point TC (° C.) and a melting point of the fiber with a second lowest melting point TD (° C.) satisfy (2):
   40° C.<( TD−TC )<150° C.   (2).
 
 
     
     
         14 . The woven textile according to  claim 2 , wherein a polyphenylene sulfide fiber and/or a meta-aramid fiber are further interwoven in addition to said yarn A and said yarn B.
