[0001]
BACKGROUND OF THE INVENTION
The present invention relates to industrial fabrics such as papermaking fabrics, conveyor belts, filter fabrics and the like.
[0002]
[Prior art]
Conventionally, fabrics woven with warps and wefts have been widely used as industrial fabrics. For example, they are used in many other fields, such as papermaking wires, conveyor belts, and filter fabrics. Woven properties are required. In particular, the demands for papermaking wires used in the papermaking process that uses the mesh of the fabric to dehydrate the raw materials are severe, and the fabric has excellent surface properties that do not transfer the fabric wire mark to the paper. Therefore, there is a demand for a fabric that has sufficient rigidity to be suitably used even in a harsh environment, and that can maintain the conditions necessary for producing good paper for a long period of time. In addition, fiber support, improvement in papermaking yield, good freeness, wear resistance, dimensional stability, running stability, and the like are required. In recent years, the speed of papermaking machines has increased, and the demand for papermaking wires has become more severe.
As described above, the papermaking fabrics, which are particularly demanding of industrial fabrics, can be understood to understand the requirements and solutions of most industrial fabrics. Therefore, the present invention will be described below on behalf of papermaking fabrics.
[0003]
For example, when the paper making speed is increased, the dewatering speed is inevitably increased, and it is necessary to increase the dewatering power. Naturally, the loss of fibers, fillers, etc. and the occurrence of wire marks become prominent, and further improvements in fiber support and surface properties are required. In addition, when the wet paper is deepened into the papermaking fabric or when the fiber is pushed in, the wet paper releasability when the wet paper is transferred to the felt also deteriorates. The wet paper formed on the fabric is pressed against the surface of the fabric by the dehydration force, so the yarn is difficult to wet in the area where the yarn is present, and conversely, the wet paper is between the mesh where there is no yarn. This is because a thread and a mesh mark are generated on the surface of the wet paper. Although it is impossible to eliminate the wire mark completely, in order to make it less noticeable as much as possible, the surface of the upper layer of the fabric must be made fine to improve surface smoothness and fiber support. However, fine woven fabrics that emphasize surface properties and fiber support are basically inferior in wear resistance because they are woven with yarns having a small wire diameter.
In addition, since the papermaking fabric travels at a high speed, there is a phenomenon in which the fabric gradually wears due to friction with a roll or the like on the traveling surface side that comes into contact with the machine, and the wear may end its life. In order to improve the wear resistance, various measures are required such as changing the fabric structure to a weft-worn type structure or changing the material of the thread. In particular, the use of a thread with a large wire diameter provides wear resistance. This method is generally used. However, although the yarn having a large wire diameter has improved wear resistance, it has been difficult to obtain excellent surface properties.
[0004]
In order to solve both the surface property and the abrasion resistance problem, two fabrics composed of different warps and wefts are used for the upper surface side layer and the traveling surface side layer, and the fabrics of both layers are connected. Two-layer fabrics integrated by tying have been used. This method has an effect that a fabric according to the performance required for each method can be adopted. A dense upper layer surface was formed using warps and wefts having a small wire diameter on the upper surface side layer, and a running surface having high wear resistance was formed using warps and wefts having a large wire diameter on the traveling surface side layer. In order to prevent the surface property from being deteriorated, generally, a yarn having a diameter smaller than that of the upper surface side warp and the upper surface side weft is used for the binding yarn. In order to form a dense surface, a plain weave is often used for the upper surface side layer structure. However, since the binding yarn is actually used to interweave the two layers, the binding yarn is formed on the substantially plain weave surface. Surfaces arranged in places will be formed. Since the binding yarn has a portion that appears on the surface in this way, it is not preferable to use a yarn having a very large wire diameter because of surface smoothness.
Also, as normal papermaking fabrics, tension is often applied in the warp direction during use, and warp yarns are hardly moved loosely by running of the fabric because warp yarns are always in tension. However, in the case of binding yarns that are often placed between wefts due to problems such as weaving properties and fiber support properties, they are stretched when tension is applied, and the binding yarns are pinched between the upper surface side layer and the running surface side layer. There was a problem that internal wear occurred and a gap was generated or separated between fabrics. This is because the endless belt is running while being laid on several rolls. At the part where the fabric comes into contact with the roll, the two-layer fabric is curved along the arc of the roll, and there is a difference in circumferential length between the layers of the fabric. Arise. As a result, the binding yarns interweaving the layers are squeezed and internal wear occurs. Internal wear is often seen in binding yarns with small wire diameter and low strength used to improve surface properties. The binding force of the upper surface side layer and the running surface side layer with only a binding yarn having a small wire diameter was insufficient. In addition, the binding yarn is entangled with the yarn on the upper surface side layer to connect the two fabrics, and the surface property of the fabric is deteriorated by giving a dent to the surface on the upper surface side to draw the yarn by the binding force. There was also.
Therefore, a multi-layer fabric using warp binding yarns that weave the upper surface side layer and the running surface side layer while forming the upper surface side surface on the warp yarn has been developed. In the upper surface side layer, the upper surface side warp and the warp binding yarn are arranged in combination with the warp forming the upper surface side surface, and the upper surface side surface is formed by weaving with the upper surface side weft. The traveling surface side layer is the traveling surface side. It was formed by warp and running surface side weft. Furthermore, for the purpose of improving the binding force and making the openings uniform, a woven fabric has been developed in which all the warp forming the upper surface side layer is a warp binding yarn. However, the conventional woven fabric has a structure in which two sets of warp ground yarn binding yarns are arranged next to one traveling surface side warp, so that the traveling surface side warp and warp ground yarn binding yarns are There was a problem in that they were not arranged one above the other, and the upper and lower layers could not be overlapped, and the freeness was lowered.
[0005]
[Problems to be solved by the invention]
In view of the above problems, the present invention is a set of two warp yarn binding yarns that are interwoven with upper surface side wefts to form a part of the upper surface side surface and connect the upper surface side layer and the running surface side layer. Two warp binding yarns which are arranged adjacent to each other and form a pair on both sides of the lower surface side warp on the traveling surface side layer are arranged adjacent to each other, and the upper surface is formed of two warps forming a pair. The warp ground yarn binding yarn and the traveling surface side warp in the vertical direction are structured such that the ground yarn binding yarns approach each other and form a structure equivalent to one upper surface side warp substantially directly above the traveling surface side warp. It is an object of the present invention to provide an industrial multilayer fabric excellent in water permeability, binding force and surface smoothness with good overlap.

DETAILED DESCRIPTION OF THE INVENTION
The industrial fabric of the present invention is used as an industrial fabric such as a papermaking wire, a conveyor belt, and a filter cloth, and can be suitably used as a papermaking wire that is particularly demanding by users.
The present invention is an industrial multilayer fabric comprising at least an upper surface side layer and a traveling surface side layer, wherein the upper surface side layer and the traveling surface side layer are connected by a warp binding yarn that weaves the upper surface side layer and the traveling surface side layer. And a part or all of the upper surface side warp was used as a warp binding yarn. Two warp binding yarns are arranged in a set, and one of the two warp binding yarns appears on the upper surface, and one upper surface side warp is formed on the upper surface side weft and the non-woven upper surface layer. Two warp binding yarns that form a pair on the running surface side layer are arranged adjacent to each other across one running surface side warp, and the upper surface is a group. Is an industrial multilayer woven fabric characterized in that two warp ground yarn binding yarns that form a shape approach each other to form a structure of one upper surface side warp substantially directly above the running surface side warp. Since this multilayer fabric has a structure in which a pair of warp binding yarns is arranged almost directly above the running surface side warp, the multilayer fabric has good overlap and can be a multilayer fabric excellent in drainage. Further, since the warp binding yarn that connects the upper surface side layer and the running surface side layer while forming a part of the upper surface side surface is used, the binding force and the surface smoothness are excellent.
[0008]
In the conventional multilayer fabric, the binding yarn connecting the two fabrics is a binding yarn having a diameter that does not affect the top surface, which has a much smaller wire diameter than the upper side warp and weft, and does not affect the weft. It was often placed in. However, an endless belt whose ends are woven by a well-known method runs on several rolls, so that the portion where the tensioned fabric comes into contact with the roll follows the arc of the roll. Since the radius of curvature is different due to the curvature of the two-layer fabric, a difference in circumferential length occurs in each layer of the fabric, whereby the binding yarn that interweaves each layer is squeezed, and when subjected to the inter-woven fabric tension, it stretches and loosens, Internal wear may occur, and the binding yarn may be cut or the fabric may be displaced to reduce the freeness.
In addition, even if the yarn is small and has a small binding force, it binds the two fabrics. In some cases, a dent was generated on the surface of the fabric, and a wire mark was given to the paper.
[0009]
Therefore, in the multilayer fabric of the present invention, warp binding yarns that connect the upper surface side layer and the running surface side layer while arranging a part of the upper surface side surface are arranged in the running direction of the fabric. In addition, the poor drainage, which has been a problem with multilayer fabrics using conventional warp binding yarns, has a structure in which warp binding yarns are arranged almost directly above the running surface side warp in the present invention. It was possible to solve it.
In the present invention, the warp ground yarn binding yarn is arranged in the running direction of the fabric. However, the main effect of binding the fabric by the warp ground yarn binding yarn is only the conventional binding. Unlike the binding yarn that does not participate in the surface texture formation, the warp ground yarn binding yarn functions as a part of the surface of the fabric, so that no local dents are generated. The warp binding yarn is used in the warp direction, that is, generally in the direction of running the fabric and is always under tension. It tends to be strong.
[0010]
The multi-layer fabric of the present invention has two warp binding yarns arranged in a pair, and in the traveling surface side layer, two warp binding yarns forming a pair sandwiching one traveling surface side warp are arranged. Two warp binding yarns appear alternately on the upper surface in the upper surface side layer to form a structure equivalent to one upper surface side weft and no upper surface side weft. . On the upper surface side surface, the two warp ground yarn binding yarns forming a set approach each other and are arranged almost directly above the traveling surface side warp yarn, forming a structure equivalent to one upper surface side warp yarn.
A multilayer fabric using warp binding yarns that form a conventional pair appears alternately on the upper surface and is interwoven with the upper weft as in the case of the multilayer fabric of the present invention. In some cases, the other warp binding yarn as a pair is interwoven with the running surface side layer to connect the two layers while forming. However, in the conventional woven fabric, a pair of warp base yarn binding yarns are arranged adjacent to each other, and the pair of warp base yarn binding yarns do not overlap vertically with other yarns. In other words, when all the warps forming the upper surface side layer are warp ground yarn binding yarns, or when the number of upper surface side warps is less than the traveling surface side warps, the traveling surface side warps are warp ground yarn binding. They will be arranged between the yarns, and they will not be arranged up and down, so that the drainage space will be blocked and the freeness will be lowered. However, in the multilayer fabric of the present invention, on the running surface side, the warp ground yarn binding yarns that are paired with one running surface side warp interposed are arranged, and on the upper surface side, the two yarns forming the set are arranged. The structure is such that warp binding yarns alternately appear on the upper surface side surface and come close to each other to form a structure of one warp substantially directly above the running surface side warp. With such a structure, the warp binding yarn and the running surface side warp are arranged one above the other so that the overlap of the warp is improved, and the problem of deterioration in drainage can be solved.
[0011]
As a preferred embodiment of the present invention, two warp base yarn binding yarns are arranged on both sides of one running surface side warp, and one warp base yarn of warp base yarn binding yarns is arranged. On the lower side where the yarn binding yarn forms the upper surface, the other warp yarn binding yarn binds the running surface side layer, and the running surface side warp passes below the running surface side weft. When passing, one warp ground yarn binding yarn adjacent to the running surface side warp passes under the running surface side weft. The traveling surface side layer has a structure in which the traveling surface side warp and one warp ground yarn binding yarn adjacent thereto pass in parallel under the traveling surface side weft. With such a structure, the warp binding yarn is less likely to move, so a stable woven fabric can be formed. Further, the traveling surface side knuckle of the warp ground yarn binding yarn and the traveling surface side knuckle of the traveling surface side warp are arranged adjacent to each other, so that the warp ground yarn binding yarn generally having a smaller diameter than the traveling surface side warp is provided. It also has the effect of reducing wear. On the upper surface, a pair of warp ground yarn binding yarns appear alternately on the upper surface, functioning just above the running surface side warp, and approaching each other, substantially like one upper surface warp To do.
There is also a method of using both the upper surface side warp and the warp ground yarn binding yarn as the warp forming the upper surface side layer. There is an effect of improving the binding force by increasing the arrangement ratio of the warp binding yarns. The structure of each of the upper surface side warp, warp binding yarn, running surface side warp and the like constituting the woven fabric is not particularly limited. However, as a papermaking woven fabric, the upper surface side layer hardly imparts the woven fabric mark to the wet paper. It is desirable to have a structure, and it is preferable that the running surface side layer has a structure that is resistant to abrasion caused by running of the fabric. On the running surface side, the running surface side warp may be arranged in the running surface side layer, and the warp ground yarn binding yarns in pairs may be arranged on both sides thereof.
The structures of the warp binding yarns that are paired may be the same or different. It is preferable that the warp binding yarns forming the upper surface side have a set of two, and do not give a mark to the paper. For example, a structure in which a plain weave is formed by combining two warp binding yarns in pairs. If the surface of the woven fabric has a plain woven structure, the number of fiber support points increases, so that the fiber support property is improved, and the texture becomes fine, so that the surface smoothness is excellent.
In the case of a structure in which the warp binding yarns are different from each other, they may be arranged in combination in the left and right directions for each set. With such an arrangement, the oblique mark appearing on the surface of the fabric can be broken, which is suitable for a papermaking fabric that places importance on the surface of the fabric.
The structure of the running surface side warp is not particularly limited, but may be appropriately determined depending on the combination with the warp binding yarn.
[0012]
The yarn used in the present invention may be selected depending on the application or the function of each yarn on the woven fabric. For example, in addition to monofilament, multifilament, spun yarn, crimp processing, bulk processing, etc. Processed yarns called doan yarns, bulky yarns, stretch yarns, or yarns obtained by combining them together can be used. Also, the cross-sectional shape of the yarn is not limited to a circle, but a short yarn such as a square shape or a star shape, an elliptical shape, or a hollow yarn can be used. In addition, the material of the yarn can be freely selected, and polyester, nylon, polyphenylene sulfide, polyvinylidene fluoride, polypro, aramid, polyetheretherketone, polyethylene naphthalate, polytetrafluoroethylene, cotton, wool, metal, etc. are used. it can. Of course, you may use the thread | yarn which blended and contained various substances according to the objective to these copolymers or these materials.
As a papermaking wire, it is generally preferable to use a polyester monofilament having rigidity and excellent dimensional stability for the upper surface side warp, the running surface side warp, and the upper surface side weft. Further, as the warp binding yarn, it is preferable to use a polyester monofilament like the upper side warp. The types and wire diameters of the upper surface side warp and warp binding yarn may be the same or different, and can be selected as needed from the nature of the fabric, weaving properties, and the like. However, since the roles of the upper surface side warp and the warp ground yarn binding yarn are different, and the warp ground yarn binding is often arranged between two warps in one set, it is preferable to use different yarns.
In addition, it is preferable to interweave polyester monofilaments and nylon monofilaments on the running surface side wefts that require abrasion resistance, for example, because the abrasion resistance can be improved while securing rigidity. Each wire diameter may be selected in accordance with the application and appropriate. Generally, it is preferable to use a relatively small diameter yarn for the upper surface side warp and the upper surface side weft to form the upper surface side layer. It is preferable to use a relatively large diameter yarn for the running surface side warp and the running surface side weft forming the side layer. In addition, the upper surface side is taken into consideration that the warp yarn binding yarn that weaves the upper surface side layer and the running surface side layer while forming the upper surface side surface with one set of two is used in one set of two. Those having a smaller diameter than the warp are preferable, but may be appropriately changed according to the intended use and the intended physical properties.

In the design diagram of FIG. 1, this example is a 10-shaft two-layer woven fabric composed of warp binding yarn, upper surface side weft, traveling surface side warp, and traveling surface side weft. All warps forming the upper surface side layer are warp ground yarn binding yarns, so that the binding force is excellent, and the surface opening is uniform because there is only one kind of warp direction yarn forming the upper surface side surface. It is also possible to make a woven fabric having excellent surface properties.
In the embodiment of FIG. 1, all of the upper surface side warps are warp base yarn binding yarns, and two warp base yarn binding yarns are arranged in a pair, and one of the two warp base yarn binding yarns is arranged.

[0015]
FIG. 1 shows an embodiment of the present invention, in which two warp binding yarns having different structures are arranged in one set, and warp binding yarns that are paired on both sides of a running surface side warp are shown. It is arranged. The two warp ground yarn binding yarns 1a pass through the upper side of one upper surface side weft 1 'to form a knuckle on the upper surface side surface, so that one upper surface side weft 2' and traveling surface side weft 2 ' And then passes through the upper side of one upper surface side weft 3 'to form a knuckle on the upper surface side, and then three upper surface side wefts 4', 5 ', 6' and traveling surface side wefts 4 ', 5 ′, 6 ′, and under one traveling surface side weft 7 ′, then three upper surface side wefts 8 ′, 9 ′, 10 ′ and traveling surface side wefts 8 ′, 9 It is a tissue passing between 'and 10'. The warp base yarn binding yarn 1b paired therewith passes between one upper surface side weft 1 'and the traveling surface side weft 1', and then passes under one traveling surface side weft 2 '. Pass between the upper surface side wefts 3 ', 4' and the traveling surface side wefts 3 ', 4', and then pass through the upper surface of one upper surface side weft 5 'to form a knuckle on the upper surface side, then one Between the upper surface side weft 6 'and the traveling surface side weft 6', and then through the upper side of one upper surface side weft 7 ', a knuckle is formed on the upper surface side surface, and one upper surface side weft 8' A knuckle is formed on the upper surface of the upper surface by passing between the traveling surface side wefts 8 ', and then passing through the upper side of one upper surface side weft 9', and then one upper surface side weft 10 'and the traveling surface side weft 10'. It is an organization that passes between. In the design drawing, these are arranged with a single running surface side warp sandwiched between them, but in an actual fabric, the warp ground yarn binding yarn 1a is arranged on the right side in the upper surface side layer. The upper side of the surface side warp 1 and the upper side of the running surface side warp 1 arranged on the left side of the warp ground yarn binding yarn 1b are arranged above one upper surface side weft and one upper surface side weft. A plain weave structure corresponding to one upper surface side warp is formed on the upper surface side by a set of two pieces alternately interwoven with the lower side. The same applies to the other 2a and 2b, 3a and 3b... 10a and 10b, and the upper surface side layer and the running surface side layer are formed while combining the warp yarns with different textures to form a plain weave on the fabric surface. The organization was interwoven.
Since one warp ground yarn binding yarn forms the upper surface side and the other warp ground yarn binding yarn is interwoven with the running surface side layer, the warp ground yarn binding On the lower side where the yarn 1a is woven with the upper surface side wefts 1 ', 2', 3 ', a pair of warp ground yarn binding yarns 1b are woven with the running surface side wefts 2'. Similarly, on the lower side where the warp base yarn binding yarn 1b is interwoven with the upper surface side wefts 5 ', 6', 7 ', 8', 9 'to form the upper surface, paired warps The ground yarn binding yarn 1a is interwoven with the running surface side weft yarn 7 '. In addition, the traveling surface side warp passes under the traveling surface side weft, and the warp ground yarn binding yarn arranged adjacent to the traveling surface side weft passes under the same traveling surface side weft. That is, in the traveling surface side warp 1, the traveling surface side warp 1 passes below the traveling surface side weft 2 ', and the warp ground yarn binding yarn 1b arranged adjacent thereto also extends below the traveling surface side weft 2'. When the traveling surface side warp 1 passes under the traveling surface side weft 7 ', the warp ground yarn binding yarn 1a disposed adjacent thereto also passes under the traveling surface side weft 7'. When the traveling surface side knuckle of the warp ground yarn binding yarn is arranged next to the traveling surface side knuckle of the traveling surface side warp in this way, two continuous warp yarns are interwoven with one weft. Therefore, it is possible to supply a stable woven fabric in which the warp binding yarn is difficult to move in the weft direction. In addition, there is also an effect of reducing the wear of the warp binding yarn having a smaller wire diameter than the running surface side warp. The upper surface side wefts and the traveling surface side wefts are arranged in the same direction in the weft direction, and the traveling surface side layer has a weft wear type structure that can withstand the abrasion caused by the traveling of the fabric. In the traveling surface side weft 1 ', after passing under the four traveling surface side warps 10, 1, 2, 3, one traveling surface side warp 4 and adjacent warp ground yarn binding yarn 4b After passing through the upper side and then the lower side of the four running surface side warps 5, 6, 7, 8, the upper side of one running surface side warp 9 and the warp ground yarn binding yarn 9a adjacent thereto As described above, the running surface side weft has a structure forming a long knuckle for four warps. The other running surface side wefts were similarly made into a weft wear type structure.
[0016]
Example 2
The embodiment of FIG. 2 is another embodiment of the present invention, and is a design diagram of an eight-shaft multilayer fabric in which the structure of warp base yarn binding yarns in the pair is the same. The arrangement of the warp and the weft in this embodiment is the same as that in the first embodiment.
On the upper surface, either one set of two warp ground yarn binding yarns appears on the upper surface on every other weft and is interwoven with the upper weft to form a plain weave structure for one warp. Yes. In the traveling surface side layer, two warp ground yarn binding yarns were arranged one by one on both sides of the traveling surface side warp. And the other warp ground yarn binding yarn passes below the running surface side weft under the one where the upper surface side surface is formed in the pair of warp ground yarn binding yarns, The upper layer and the lower layer were interwoven. The traveling surface side warp passes through the upper side of the three traveling surface side wefts, and then passes under the traveling surface side weft. The traveling surface side warp of the traveling surface side warp is 2 in one cycle. It is an organization that repeats the organization that is placed once.
The warp ground yarn binding yarns that are paired approach each other on the upper surface side surface, and are arranged like one upper surface side warp substantially directly above the traveling surface side warp. Since the warp yarns are arranged one above the other, the fabric is excellent in drainage. In addition, the traveling surface side knuckle of the traveling surface side warp and the traveling surface side of the warp ground yarn binding yarn are arranged in parallel on the traveling surface side surface so that the warp ground yarn binding yarn is difficult to move. In addition, the wear of the warp binding yarn having a smaller diameter than the running surface side warp can be reduced.
The warp base yarn binding yarn is a structure in which two pieces of the same structure are combined, and the warp base yarn binding yarns are arranged on both sides of the running surface side warp. The structure of the warp binding yarn is as follows. The warp binding yarn 1a passes through the upper side of one upper surface side weft 1 'to form a knuckle on the upper surface surface, and the upper surface side weft 2' Passing between the running surface side wefts 2 ', then passing the upper side of one upper surface side weft 3', a knuckle is formed on the upper surface side surface, then the two upper surface side wefts 4 ', 5' and the running surface side It passes between the wefts 4 'and 5', and passes under the one running surface side weft 6 ', then the two upper surface side wefts 7' and 8 'and the running surface side wefts 7' and 8 '. It is an organization that passes between them. The warp binding yarn 1b paired with it has the same structure, one of which forms the upper surface side layer and the other weaves the traveling surface side layer. A plain weave structure is formed on the upper surface side like one upper surface side warp above the side warp. The same applies to the other 2a and 2b, 3a and 3b... 10a and 10b, and the upper surface side layer and the running surface side are formed by combining plain warp binding yarns having the same structure to form a plain weave on the fabric surface. The layers were woven into a woven fabric excellent in binding force, surface smoothness and stability.

Example 3
The embodiment of FIG. 3 is another embodiment of the present invention. The warp base yarn binding yarns in a pair have different structures, and the upper surface side surface warp and the warp base yarn binding yarn are different from each other. It is a design drawing of a 10-shaft multilayer fabric.
On the upper surface side, one set of two warp ground yarn binding yarns appears on the surface every other weft and is interwoven with the upper surface side weft to form a plain weave structure for one warp. On the side, one upper surface side warp is interwoven with the upper surface side weft to form a plain weave structure on the upper surface. By these two types of warps, a plain weave structure is formed as a whole on the upper surface. In the traveling surface side layer, two warp ground yarn binding yarns were arranged one by one on both sides of the traveling surface side warp. And the other warp ground yarn binding yarn passes below the running surface side weft under the one where the upper surface side surface is formed in the pair of warp ground yarn binding yarns, The upper layer and the lower layer were interwoven. The traveling surface side warp passes through the upper side of the four traveling surface side wefts and then passes through the lower side of one traveling surface side weft. The traveling surface side warp of the traveling surface side warp is twice in one cycle. It is an organization in which the organization to be arranged is repeated.
The warp ground yarn binding yarns that are paired approach each other on the upper surface side surface, and are arranged like one upper surface side warp almost directly above the running surface side warp. The freeness can be improved by arranging the warps vertically. In addition, on the running surface side surface, the running surface side knuckle of the running surface side warp and the running surface side of the warp ground yarn binding yarn are arranged in parallel, making it difficult for the warp yarn binding yarn to move, In general, there is an effect that it is possible to reduce the wear of the warp binding yarn having a smaller diameter than the running surface side warp. The fabric of the present invention is also excellent in binding force, surface smoothness, and stability.
The warp yarn binding yarn is the same as in Example 1, and is a structure in which two yarns having different textures are combined. The warp yarn binding yarns arranged in pairs on both sides of the running surface side warp are arranged.
[0018]
Example 4
The embodiment of FIG. 4 is another embodiment of the present invention, in which the warp base yarn binding yarns in a pair have different structures, and their arrangement order is alternated. The structure of the warp binding yarn, the other structure, the constituent yarn, and the like are the same as those in the first embodiment.
Two warp binding yarns 1a having different textures form a knuckle on the upper surface through the upper side of one upper surface side weft 1 ', and one upper surface side weft 2' A knuckle is formed on the surface of the upper surface side through the running surface side wefts 2 'and then through the upper side of one upper surface side weft 3', and then three upper surface side wefts 4 ', 5', 6 ' Passes between the running surface side wefts 4 ', 5', 6 'and under the one running surface side weft 7', then travels with the 3 upper surface side wefts 8 ', 9', 10 ' It is a structure passing between the surface side wefts 8 ', 9', 10 '. The warp base yarn binding yarn 1b paired therewith passes between one upper surface side weft 1 'and the traveling surface side weft 1', and then passes under one traveling surface side weft 2 '. Pass between the upper surface side wefts 3 ', 4' and the traveling surface side wefts 3 ', 4', and then pass through the upper surface of one upper surface side weft 5 'to form a knuckle on the upper surface side, then one Between the upper surface side weft 6 'and the traveling surface side weft 6', and then through the upper side of one upper surface side weft 7 ', a knuckle is formed on the upper surface side surface, and one upper surface side weft 8' A knuckle is formed on the upper surface of the upper surface by passing between the traveling surface side wefts 8 ', and then passing through the upper side of one upper surface side weft 9', and then one upper surface side weft 10 'and the traveling surface side weft 10'. It is an organization that passes between. In the next set 2a and 2b of warp base yarn binding yarns, the arrangement order of the warp base yarn binding yarns is arranged opposite to the pair 1a and 1b. In other words, the same tissue as 1a that formed two knuckles on the upper surface was placed in 2b, and the same tissue as 1b that formed three knuckles was placed in 2a.
In this way, by alternately arranging the arrangement order of the two warp binding yarns that form the upper surface side surface, oblique marks formed by the upper surface side warp appearing on the upper surface side can be reduced. .
Since the warp binding yarns in a pair are close to each other and arranged like a single upper surface side warp almost directly above the running surface side warp, a woven fabric having excellent drainage can be obtained. In addition, the traveling surface side knuckle of the traveling surface side warp and the traveling surface side knuckle of the warp ground yarn binding yarn are arranged in parallel on the traveling surface side surface, so that the movement of the warp ground yarn binding yarn is less likely to occur and is stable. It can be made into a woven fabric and generally has an effect of reducing the wear of the warp binding yarn having a smaller diameter than the running surface side warp.

【The invention's effect】
The industrial multilayer fabric of the present invention is a multilayer fabric in which warp yarn binding yarns that form a part of the upper surface side surface and interweave the upper surface side layer and the running surface side layer are arranged. Since the two sets are arranged in one set, the binding is very strong. In the running surface side layer, the two warp ground yarn binding yarns forming the set are arranged adjacent to both sides of the running surface side warp. In the upper surface, two warp binding yarns forming a pair appear alternately on the upper surface, and approach each other to form a structure equivalent to one upper surface warp substantially directly above the running surface warp. Since it is a two-layer woven fabric, it is excellent in drainage, does not cause partial dents on the fabric surface, and exhibits excellent effects in stability and surface smoothness.
