An industrial textile (6) for manufacturing a fibrous web has first machine direction yarns (1) on the front side (7) which bind to first cross-machine direction yarns (4) in a first pattern, while second machine direction yarns (2) on the back side bind to second cross-machine direction yarns (5) in a second pattern. Third machine direction yarns (3) bind to the first cross-machine direction yarns (4) and the second cross-machine direction yarns (5) in a third pattern. The third pattern has at least one interlacing point (71) on the front side where one of the third machine direction yarns (3) passes over one of the first cross-machine direction yarns (4) and at least one interlacing point (72) on the back side (8) where the same third machine direction yarn (3) passes under one of the second cross-machine direction yarns (5).

Clothing is provided for a machine for producing a fibrous web, in particular a paper, board or tissue web. The clothing has a substrate. The substrate has a top side, an underside, two side edges and a useful region between the two side edges. The useful region has a plurality of through-channels, which connect the top side to the underside of the substrate. An inner surface of at least one through-channel, preferably of the majority of all the through-channels, more preferably of all the through-channels in the useful region of the substrate, has a mean roughness depth that is greater than 4 μm, preferably greater than 6 μm, more preferably greater than 8 μm. The clothing of this type is produced using a laser.

The invention relates to a clothing (10) for a machine to manufacture or refine a fibrous web, in particular a paper, cardboard, or tissue web, comprising a substrate (40) and a grid structure (20) applied on the substrate (40), on which the fibrous web is transported when the clothing (10) is used as intended, wherein the grid structure (20′) comprises a plurality of first elements (24′), all of which aligned in a first direction, and a plurality of second elements (26′), all of which aligned in a second direction, which is different from the first direction, wherein the first elements (24′) penetrate the second elements (26′), forming the grid structure (20′), such that an underside of the first elements (24′) facing the substrate (40) and an underside of the second elements (26′) facing the substrate (40) are located in a common plane.

An industrial textile has two layers, a web-side layer and a wear-side layer. The web-side layer has machine direction yarns (1) and binding cross-machine direction yarns (5). The wear-side layer has machine direction yarns (3) and cross-machine direction yarns (4). The binding cross-machine direction yarns (5) extend from the web-side layer to the wear-side layer and bind a portion of the wear-side layer machine direction yarns (3) to bond the web-side layer and the wear-side layer together, and wherein the web-side layer is a non-plain weave.

An industrial fabric 100 is an industrial fabric in which an upper surface side fabric composed of upper surface side warps and upper surface side wefts and a lower surface side fabric composed of lower surface side warps and lower surface side wefts are bound to each other, wherein an upper surface side warp 1Ub functions as an upper surface side binding yarn binding the upper surface side fabric and the lower surface side fabric, and a lower surface side warp 2Lb functions as a lower surface side binding yarn binding the upper surface side fabric and the lower surface side fabric. The number of knuckles formed by the upper surface side warp 1Ub in the upper surface side fabric is larger than the number of knuckles formed by the lower surface side warp 2Lb in the upper surface side fabric.

[Task] The object of the present invention is to provide an industrial two-layered fabric with a long durability which exhibits an excellent surface smoothness and excellent marking characteristics, while at the same time improving wear resistance characteristics to balance warps and wefts. [Solution to the Task] An industrial two-layered fabric formed by binding yarns, diameters of all of the upper surface side warps are set to be the same, diameters of all of the lower surface side warps are set to be the same, diameters of the lower surface side warps are set to be larger than diameters of said upper surface side warps, and at least one, or more than one of said upper surface side warps are woven with said lower surface side wefts to constitute binding yarns binding said at least one upper surface side fabric and said at least one lower surface side fabric.

An industrial two-layer fabric of the contact-yarn binding type without independent binding yarns, at both ends. The upper surface side warp serving as the warp fabric yarn-contact binding yarn is not woven into the upper surface side weft at one or more points of a complete structure, and extends toward the lower surface side instead and is woven into the lower surface side weft at the lower surface side, and then, extends toward the upper surface sides to be woven into other upper surface side weft, while, the lower surface side warp is not woven into the lower surface side weft at a point where the upper surface side warp serving as the warp fabric yarn-contact binding yarn is woven into the lower surface side weft at the lower surface side, and extends toward the upper surface side instead to be woven into the upper surface side weft which is not woven into the upper surface side warp, at the upper surface side, and then extends toward the lower surface side to be woven into other lower surface side weft. The industrial two-layer fabric forms a joint loop by at least one end portion of the warp being turned back at both end portions in its longitudinal direction, and at least a longitudinal yarn in a complete structure includes at least one warp which forms a pair arranged to be opposite to the warp which is turned back for forming the joint loop, and, in a longitudinal structure, the number of knuckles of one of the warps forming the pair is the same as that of the other of the warps forming the pair and distances between said adjacent knuckles are substantially the same.

A fabric having a first woven fabric layer forming a paper side and made of first threads, and a second woven fabric layer made of second threads, the two woven fabric layers being connected by binder threads belonging to the first woven fabric layer such that at binding points the respective binder thread binds with one first thread on the paper side, then changes to the second woven fabric layer and binds with at least two second threads and then returns to the first woven fabric layer again and binds with a first thread on the paper side, wherein at binding points only one first thread is not bound by the said binder thread.
