To obtain a paper-making woven fabric having more improved smoothness than those of conventional paper-making woven fabrics, to provide a method for processing the paper-making woven fabric, and to provide a processing device used for the processing.

This paper-making woven fabric 1 having a two-layered structure comprises double warps and double wefts, and which comprises a paper-making surface side woven fabric layer 2 formed by weaving paper-making surface side warps 21 with paper-making surface side wefts 22 and a traveling surface side woven fabric layer 3 formed by weaving traveling surface side warps 31 with traveling surface side wefts 32, in which binders 4 are woven to bind the paper-making surface side woven fabric layer 2 to the traveling surface side woven fabric layer 3, and in which a surface-polishing treatment is applied to the paper-making surface side woven fabric layer 2 in a thickness of ≥50 μm. The paper-making woven fabric has more improved smoothness than those of conventional paper-making woven fabrics, and can still maintain the strengths of the paper-making woven fabrics, especially strengths related to the joined portions of the paper-making woven fabric.
