Woven textile

Abstract

The woven textile has a first end and an opposite second end. A longitudinal direction is defined by the first end and the second end. The woven textile includes an upper layer, a lower layer, and at least one binding thread. The upper layer includes at least one first braid woven by a plurality of filaments and extending in a meandering way to form a plurality of hollow portions. The lower layer includes at least one second braid woven by a plurality of filaments and extending in a meandering way to form a plurality of hollow portions. The binding thread fixes the first braid and the second braid together by weaving so that the upper layer and the lower layer are positioned by the binding thread.

What is claimed is: 
     
         1 . A woven textile, having a first end and an opposite second end, a longitudinal direction being defined by the first end and the second end, the woven textile including:
 an upper layer, including at least one first braid, the first braid being woven by a plurality of filaments and extending in a meandering way to form a plurality of hollow portions;   a lower layer, including at least one second braid, the second braid being woven by a plurality of filaments and extending in a meandering way to form a plurality of hollow portions;   at least one binding thread, fixing the first braid and the second braid together by weaving so that the upper layer and the lower layer are positioned by the binding thread.   
     
     
         2 . The woven textile of  claim 1 , wherein the upper layer includes a plurality of said first braids, the first braids extend along the longitudinal direction, the lower layer includes a plurality of said second braids, the second braids extend along the longitudinal direction, the woven textile includes a plurality of binding threads, each binding thread fixes at least one of the first braids and at least one of the second braids together by weaving. 
     
     
         3 . The woven textile of  claim 2 , wherein each first braid extends wavily to have a plurality of first crests and a plurality of first troughs arranged alternatively, the first crests are closer to the first end than the first troughs are, the first troughs are closer to the second end than the first crests are, each second braid extends wavily to have a plurality of second crests and a plurality of second troughs arranged alternatively, the second crests are closer to the first end than the second troughs are, the second troughs are closer to the second end than the second crests are. 
     
     
         4 . The woven textile of  claim 3 , wherein the first crests positionally correspond to each other, the second crests positionally correspond to each other. 
     
     
         5 . The woven textile of  claim 4 , wherein each first crest of each first braid is located between two adjacent second crests of one of the second braids so that the first braids are complementary to the second braids. 
     
     
         6 . The woven textile of  claim 5 , wherein each first crest of each first braid is located between two adjacent first troughs of the first braid adjacent thereto, each first trough of each first braid is located between two adjacent first crests of the first braid adjacent thereto, each second crest of each second braid is located between two adjacent second troughs of the second braid adjacent thereto, each second trough of each second braid is located between two adjacent second crests of the second braid adjacent thereto. 
     
     
         7 . The woven textile of  claim 2 , wherein each of the first braids and the second braids is woven by braiding. 
     
     
         8 . The woven textile of  claim 2 , wherein each first braid includes an outer layer and a core, the outer layer is braided by a plurality of said filaments to be tubular, the core is inserted through the outer layer, each second braid includes an outer layer and a core, the outer layer is braided by a plurality of said filaments to be tubular, the core is inserted through the outer layer. 
     
     
         9 . The woven textile of  claim 1 , wherein an overlapping area of the hollow portions of the upper layer and the hollow portions of the lower layer form a plurality of through holes, each through hole is surrounded by part of the first braid and part of the second braid. 
     
     
         10 . The woven textile of  claim 1 , wherein a direction of a normal line of each of the upper layer and the lower layer is defined as a vertical direction, each of the first braids, the second braids, and the binding threads extends along a horizontal direction, the horizontal direction is perpendicular to each of the longitudinal direction and the vertical direction.
