Abstract

TECHNICAL PROBLEMS TO BE SOLVED BY PRESENT INVENTION The object of the present invention is to provide the industrial two-layer fabric which can make papers to be made with a lateral strength higher than that of the fabric constituted by one kind of the conventional upper surface side yarns structure by overcoming the technical difficulty in the adjustment of the fiber orientation due to the complicated factors such as a turbulence generated in the jet stream, the control of the ration J/W, etc. MEANS TO SOLVE TECHNICAL PROBLEMS In the industrial two-layer fabric comprising an upper surface side fabric consisting of upper surface side warps and upper surface side wefts and a lower surface side fabric consisting of lower surface side warps and lower surface side wefts, the upper and lower surface side fabric being bound by foundation binding yarns, all structure portions of the upper surface side warps among a structure constituting said upper surface side fabric are the same, said upper surface side wefts comprises first upper surface side wefts and second upper surface side wefts, structures forming the first upper surface side wefts are different from those forming the second upper surface side wefts.

Dependent claims

An industrial two-layer fabric comprising:

an upper surface side fabric comprising upper surface side warps and upper surface side wefts;
and
a lower surface side fabric comprising lower surface side warps and lower surface side wefts;
wherein,
the upper surface side fabric and the lower surface side fabric being bound by warp binding yarns, the upper surface side warps include the warp binding yarns and non-binding upper surface side warps that are woven with the upper surface side wefts only;
said upper surface side wefts consist of first upper surface side wefts and second upper surface side wefts,
each of the first upper surface side wefts forms a first weaving design structure in a minimum repeated unit,
each of the second upper surface side wefts forms a second weaving design structure in the minimum repeated unit, the first weaving design structure is different from the second weaving design structure;
a number of the upper surface side wefts in the minimum repeated unit where each of the upper surface side warps that include the non-binding upper surface side warps passing above the upper surface side wefts to form knuckles is less than a number of the upper surface side wefts in the minimum repeated unit where each of the non-binding upper surface side warps passing below the upper surface side wefts.
