Industrial fabric with double weft and single weft

摘要

An object of the present invention is to provide an industrial fabric which is capable of improving a surface smoothness by restricting a formation of a knuckle by wefts on a fabric surface. Another object of the present invention is to provide an industrial fabric of a double warps-single weft type which is capable of improving a rigidity, an wear resistance, and a permeability. An object of the present invention is to provide an industrial fabric which is capable of controlling an on-stack structure of an upper surface side warp and lower surface side warp. An object of the present invention is to provide an industrial fabric which is capable of improving an anti-dirt effect on the upper surface side and lengthening the durability of a product, while at the same time of keeping the strength of weaving the upper surface side and the lower surface side, in a case where yarns exposed to the upper surface side are formed by the ones which include an anti-dirt effect such as fluorine resin. The present invention includes an industrial fabric of double warps-single weft woven type wherein at least an upper surface side warp and a lower surface side warp are laminated to be woven by a plurality of wefts comprises an auxiliary weft are kept arranged between the upper surface side warp and the lower surface side warp without the upper and lower surface warps being woven with each other between the adjacent wefts.
