Woven textile

Abstract

The woven textile includes an upper layer, a lower layer, a binding thread, and a third braid. The upper layer and the lower layer include at least one first braid and at least one second braid respectively. The first and the second braids extend in a meandering way to form a plurality of hollow portions. The upper layer and the lower layer overlap to have plural overlapping portions aligned along the horizontal direction. Plural rows of said overlapping portions are arranged along the longitudinal direction. The binding thread fixes the overlapping portions in a same row together by weaving so that the upper layer and the lower layer are positioned. The third braid fixes the overlapping portions of a same row with the overlapping portions of an other same row by weaving so that a distance between said two rows of overlapping portions is restricted.

What is claimed is: 
     
         1 . A woven textile, having a first end and a second end, a longitudinal direction being defined by the first end and the second end, a horizontal direction being defined perpendicular to the longitudinal direction, 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, the upper layer and the lower layer overlapping to have a plurality of overlapping portions, the overlapping portion being aligned along the horizontal direction, a plurality of rows of said overlapping portions being arranged along the longitudinal direction;   at least one binding thread, fixing the overlapping portions at least in a same row together by weaving so that the upper layer and the lower layer are positioned by the binding thread;   at least one third braid, the third braid fixing at least one of the overlapping portions of a same row with at least one of the overlapping portions of an other same row by weaving so that a distance between said two rows of overlapping portions is restricted by the third braid.   
     
     
         2 . The woven textile of  claim 1 , wherein the upper layer includes a plurality of said first braids, the lower layer includes a plurality of said second braids, a plurality of said binding threads and a plurality of said third braids fix the upper layer and the lower layer together by weaving. 
     
     
         3 . The woven textile of  claim 2 , wherein each of the first braids and each of the second braids extend wavily respectively, crests and troughs of the first braid and the second braid in a same row are staggered, the overlapping portions are formed at positions where the first braid overlaps the second braid in an adjacent row and positions where the second braid overlaps the first braid in an adjacent row. 
     
     
         4 . The woven textile of  claim 2 , wherein each of the first braids, each of the second braids, and each of the third braids are woven by braiding. 
     
     
         5 . The woven textile of  claim 2 , wherein each of the first braids includes an outer layer and a core, the outer layer is woven by a plurality of filaments to be tube-shaped, the core is inserted through the outer layer, each of the second braids includes an outer layer and a core, the outer layer is woven by a plurality of filaments to be tube-shaped, the core is inserted through the outer layer. 
     
     
         6 . The woven textile of  claim 1 , wherein area where the hollow portions of the upper layer overlap the hollow portions of the lower layer forms a plurality of through holes, each through hole is surrounded by part of the first braid and part of the second braid. 
     
     
         7 . The woven textile of  claim 1 , wherein the third braid is woven with one row of the overlapping portions and at least part of the binding thread woven with said row of the overlapping portions, extends toward a direction, further woven with an other row of the overlapping portions and at least part of the binding thread woven with said row of the overlapping portions, and extends toward said direction so that the third braid extends in step-shaped path.
