Abstract: An industrial two-layer fabric includes an upper side fabric and a lower side fabric. The upper side warps of the upper side fabric comprise a first warp set and a second warp set. The first warp set contains two upper side warps and a warp binding yarn that binds the upper side fabric and the lower side fabric. The two upper side warps are woven with the same upper side wefts. The second warp set contains one upper side warp. At a position where the warp binding yarn passes above one of the upper side wefts, the warp binding yarn is placed between the two upper side warps of the first warp set and pass below the same one of the upper side wefts, whereby the two upper side warps and the warp binding yarn of the first warp set form the upper side warp design.

Abstract: An industrial two-layer fabric has an inner space between an upper side fabric and a lower side fabric. Some or all of upper side wefts or lower side wefts are secondary wefts interwoven with upper side warps or lower side warps so as to make the number of warps passing on an upper surface of the upper side fabric or passing on a lower surface of the lower side fabric larger than that on an inner space side of the upper or lower side fabric and a long crimp in the inner space is formed by the secondary weft.

Abstract: An industrial two-layer fabric includes a first warp set and a second warp set that are placed alternately and form a weave design of the upper side fabric. The first warp set contains two upper side warps. At least one of the upper side warps of the first warp set functions as a warp binding yarn that binds the upper side fabric and the lower side fabric. The second warp set contains one of upper side warps and one of lower side warps placed below the one of the upper side warps. At a position where two adjacent lower side warps are woven with one of the lower side wefts, the warp binding yarn placed between the two adjacent lower side warps is woven with the same one of the lower side wefts.

Abstract: In an industrial multilayer fabric, narrower wefts of a small diameter are placed between lower side wefts so as to sandwich a knuckle formed by a lower side warp on the lower surface side of the fabric. The industrial fabric is obtained by stacking at least upper side wefts and lower side wefts one after another and weaving these wefts with warps. Narrower wefts that have a smaller diameter than that of the lower side wefts and form a shorter crimp than that formed by the lower side wefts on the lower side surface are arranged between the lower side wefts. And at a knuckle portion formed by warps passing under one or two successive lower side wefts, the narrower wefts form a crimp passing under lower side warps so as to sandwich, from both sides, one knuckle or two knuckles formed by two adjacent warps under two adjacent wefts.

Abstract: The industrial two-layer fabric has at least warp binding yarn pairs having an upper side warp and a warp binding yarn arranged vertically. On the upper side, between knuckles that two adjacent upper side warps have formed by passing over one or two upper side wefts, a warp binding yarn passes over one upper side weft to form a knuckle, whereby knuckles of the upper side warp, the warp binding yarn, and the upper side warp are formed in the mention of order over the one upper side weft. In the industrial two-layer fabric thus formed, the knuckle of the warp binding yarn does not protrude further than the knuckle of the upper side warps.

Abstract: The object of the present invention is to provide an industrial two-layer fabric which exhibits good hydration property and good air permeability by forming a longitudinal groove on its upper surface side through a weave design without decreasing the number of warps, while at the same time exhibits good fiber supportability, good surface smoothness and high rigidity.

Abstract: A two layer fabric has first, second, third and fourth upper side wefts contiguously and repeatedly arranged. Each of three contiguously arranged warps forms a knuckle over second, over third, and over second upper side wefts respectively to form a separation portion. At both sides of the separation portion, both the second and third upper side wefts form a float portion by passing over two or more warps. Adjacent to the float portion, one warp passes over the second and third upper side wefts successively and one or two warps adjacent thereto pass over the second or the third upper side weft to form an approach portion where the second and third upper side wefts approach. Crimp portions are formed to sandwich the separation portion where the first and fourth upper side wefts pass over warps which are common to those of the separation portion.

Abstract: In an industrial multilayer fabric, narrower wefts of a small diameter are placed between lower side wefts so as to sandwich a knuckle formed by a lower side warp on the lower surface side of the fabric. The industrial fabric is obtained by stacking at least upper side wefts and lower side wefts one after another and weaving these wefts with warps, wherein narrower wefts having a smaller diameter than that of the lower side wefts and forming a shorter crimp than that formed by the lower side wefts on the lower side surface are arranged between the lower side wefts; and at a knuckle portion formed by warps passing under one or two successive lower side wefts, the narrower wefts form a crimp passing under lower side warps so as to sandwich, from both sides, one knuckle or two knuckles formed by two adjacent warps under two adjacent wefts.

Abstract: In an industrial two-layer fabric, one upper surface side warp and three warp binding yarns are disposed adjacent to each other. Each of the three warp binding yarns appears on the upper side surface in turn and passes over different one or two successive upper surface side wefts. At least one upper surface side weft exists between knuckles formed on the upper side surface by the three warp binding yarns. Adjacent to the upper surface side warp, these three warp binding yarns get together to form on the upper side surface a design which is the same design formed by an upper surface side warp.

Abstract: An industrial two-layer fabric includes pairs of warps obtained by stacking an upper side warp to be woven with an upper side weft and a lower side warp to be woven with a lower side weft and having, as at least one of the pairs. A pair of binding warps includes warp binding yarns to be woven with both an upper side weft and a lower side weft constitutes a portion of an upper side surface design and a portion of a lower side surface design. In a lower side surface warp design formed by the weaving of a warp binding yarn and a lower side warp with a lower side weft, two or three designs are different from each other, and a weft passes over two warps adjacent to each other and then passes under a plurality of warps to form a long crimp on the lower side surface.

Abstract: In an industrial two-layer fabric, either one of an upper side binding yarn and a lower surface binding yarn constituting a pair to be woven with an upper surface weft and a lower side weft passes under one lower surface weft and then passes over a plurality of lower surface wefts. A warp on one adjacent side of the one of the upper and lower surface binding yarns has a similar design thereto and passes over and under the same lower surface wefts. The design of a set of the two warps adjacent to each other is shifted and arranged one after another to form a complete design of the lower surface fabric and a lower surface weft has a design in which the weft passes over two successive warps and then passes under a plurality of warps to form a long crimp on the lower surface.

Abstract: In a repeating unit of a two-layer fabric, a first upper surface side warp forms a first upper surface side warp design. A second upper surface side warp forms a latent portion in which the second upper surface side warp passes between the two layers of the fabric. A first lower warp binding yarn and a second lower warp binding yarn form first and second knuckles respectively by passing over one or two upper surface side wefts at a position not adjacent to two knuckles of the second upper surface side warp in the latent portion. The first and second knuckles are formed at different positions. The first lower warp binding yarn, second upper surface side warp and second lower warp binding yarn cooperatively form a second upper surface side warp design similar to the first upper surface side warp design.

Abstract: An industrial two-layer fabric having eight upper side warps and eight lower warps are stacked vertically forming upper and lower layers which are bound by a warp binding yarn of these warps. In a repeating unit of the upper layer, one of the warps has repetition of a design in which it passes over one upper side weft, passes under four successive upper side wefts, passes over one upper side weft, and passes under two upper side wefts, and an upper side weft has a design in which it passes over three upper side warps and then passes under one upper side warp to form, on the upper side, a weft long crimp corresponding to three warps, whereby forming an industrial fabric excellent in running stability, surface property and wear resistance.

Abstract: In a lower surface side layer of an industrial two-layer fabric, warps are formed by sequentially arranging a repeating design unit, in which one warp passes over six successive lower surface side wefts, passes under one lower surface side weft, passes over two lower surface side wefts, and passes under one lower surface side weft while shifting the design by three lower surface side wefts. Two adjacent lower surface side warps simultaneously weave therein, from the lower surface side, one lower surface side weft, whereby the lower surface side weft passes over two lower surface side warps and then passes under eight lower surface side warps to form a weft long crimp corresponding to eight lower surface side warps on the lower surface side surface.
