Industrial two-layer fabric

Abstract

Provided is an industrial two-layer fabric satisfying basic characteristics of a fabric. The industrial two-layer fabric pertaining to the present invention has at least a first structure and a second structure in the weave repeat thereof, the first structure being formed by a combination of two upper-surface-side warps and a single lower-surface-side warp, the second structure being formed by a single upper-surface-side warp and a single lower-surface-side warp, the first structure and the second structure being disposed adjacent to each other, the upper-surface-side warps in the first structure being formed by a warp binding yarn having the function of binding an upper-surface-side fabric and a lower-surface-side fabric, the combination of two upper-surface-side warps forming the first structure being disposed adjacent to each other and constituting a partial rib weave at the surface of the upper-surface-side fabric.

1 . An industrial two-layer fabric comprising an upper-surface-side fabric formed from upper-surface-side warps and upper-surface-side wefts, lower-surface-side warps, and lower-surface-side wefts, wherein the industrial two-layer fabric has at least a first structure and a second structure in a weave repeat thereof, the first structure being formed by a combination of two upper-surface-side warps and a single lower-surface-side warp, the second structure being formed by a single upper-surface-side warp and a single lower-surface-side warp, the first structure and the second structure being disposed adjacent to each other, the upper-surface-side warps in the first structure being formed by a warp binding yarn having the function of binding an upper-surface-side fabric and a lower-surface-side fabric, the combination of two upper-surface-side warps forming the first structure being disposed adjacent to each other and constituting a partial rib weave at the surface of the upper-surface-side fabric, the diameter of the lower-surface-side warp being larger than the diameter of the upper-surface-side warp forming the first structure, and the upper-surface-side warp in the second structure being formed by a flat warp. 
     
     
         2 . The industrial two-layer fabric according to  claim 1 , wherein the diameter of the lower-surface-side warp forming the first structure is 130% to 300% of the diameter of the upper-surface-side warp forming the first structure. 
     
     
         3 . The industrial two-layer fabric according to  claim 1 , wherein the aspect ratio of the flat warp is 1.1 to 2.0 in the second structure. 
     
     
         4 . The industrial two-layer fabric according to  claim 2 , wherein the aspect ratio of the flat warp is 1.1 to 2.0 in the second structure. 
     
     
         5 . The industrial two-layer fabric according to  claim 1 , wherein the first structure and the second structure are formed being arranged alternately. 
     
     
         6 . The industrial two-layer fabric according to  claim 2 , wherein the first structure and the second structure are formed being arranged alternately. 
     
     
         7 . The industrial two-layer fabric according to  claim 3 , wherein the first structure and the second structure are formed being arranged alternately. 
     
     
         8 . The industrial two-layer fabric according to  claim 4 , wherein the first structure and the second structure are formed being arranged alternately.
