Description

  The present invention relates to an industrial fabric using warp binding yarns that satisfies physical properties required for an industrial fabric such as abrasion resistance, surface properties, rigidity, running stability, and drainage.

Conventionally, fabrics woven with warp and weft yarns have been widely used as industrial fabrics. For example, they are used in many other fields such as papermaking wires, conveyor belts, filter fabrics, etc. Appropriate textile properties are required. In particular, the demand for papermaking wires used in the papermaking process that uses the mesh of the fabric to dewater the raw materials is severe, and the fabric has excellent surface properties that make it difficult to transfer the fabric wire mark to the paper. There is a demand for a fabric that has sufficient wear resistance and rigidity that can be suitably used underneath, and that can maintain the conditions necessary for producing good paper for a long period of time. In addition, fiber support, improvement in paper yield, good freeness, 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 the most 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.
Especially as a papermaking fabric, it is difficult to transfer the wire mark of the fabric to the paper, excellent surface properties, fiber support to stop fine fibers, wear resistance that can run for a long time even under harsh running conditions, stable until the end of use Running stability, rigidity, etc. that can run are very important. Research on the structure and composition is progressing as a fabric that satisfies these requirements, but recently, a two-layer fabric is used in which a part of the upper side warp and the lower side warp are combined into a warp binding yarn. ing. The warp binding yarn has a binding function to interweave with both the upper surface side weft and the lower surface side weft. At the same time, the upper surface side warp and the lower surface side form part of the upper surface and the lower surface. It also has the same function as warp.
Japanese Unexamined Patent Application Publication No. 2003-342889 also discloses a two-layer fabric using warp binding yarns. Since this fabric uses warp binding yarns, there is no additional binding yarns, and since the upper surface side fabric structure is not destroyed, the surface properties are excellent. In addition, the binding strength is excellent even when compared with the weft binding fabric. However, in the woven fabric described in this publication, the lower surface side weft constituting the lower surface side surface is a structure passing through the upper side of the two warps and then the lower side of the two warps. A short weft crimp is formed. Generally, the lower surface contacting the machine or roll may have a lower weft long crimp structure that causes the weft to be worn. The woven fabric disclosed in Japanese Patent Application Laid-Open No. 2003-342889 has a structure in which the lower surface side weft passes above the two warps and then passes below the two warps in the lower surface woven fabric. In this woven fabric, a drainage space is formed between adjacent warp pairs on the lower surface side, and it is suitable for a woven fabric for tissue manufacture having a thin mesh thickness by being composed of a small diameter yarn. . This fabric has a structure suitable as a tissue-making fabric having a thin mesh thickness, but is not suitable for applications requiring wear resistance and rigidity. Wear resistance tends to be improved if the lower side weft is made of a long crimp structure. However, in fabrics using warp binding yarns, the fabric structure is limited by the wire diameter, fabric structure and application, etc. There is a case. For example, even if a large-diameter yarn is used for the lower surface side weft of the fabric of this structure for the purpose of wear resistance, the lower surface side weft is difficult to bend, so that the warp yarns appearing on the lower surface side are likely to protrude and wear easily.
As described above, an industrial fabric satisfying all of abrasion resistance, surface property, rigidity, running stability, and drainage has not been developed yet in a fabric using warp binding yarns.

About.

  In the industrial two-layer fabric of the present invention, the lower surface side surface structure formed by weaving the warp binding yarn and the lower surface side warp with the lower surface side weft is the lower surface side surface structure composed of three different warp structures. The warp binding yarn forming the pair is a left and right uniform structure based on the lower side knuckle, and / or the warp binding yarn forming the pair is the same structure, can do.

The industrial fabric of the present invention has an upper surface side warp interwoven with the upper surface side weft and a lower surface side warp interwoven with the lower surface side weft, and one upper surface side warp and lower surface side warp always form a pair. They are arranged almost vertically to form a “warp pair”, at least one of which is interwoven with both the upper surface side wefts and the lower surface side wefts, and the upper surface surface texture and the lower surface texture A double-layered woven fabric, which is a “set of binding warps” composed of two warp binding yarns that form part of the warp binding yarn, and the warp binding yarns and the lower surface side warp yarn are the lower surface side wefts The warp structure on the lower surface side formed by weaving together is composed of three different warp structures, and the weft structure passes through the upper side of two adjacent warp yarns, and then passes under the multiple warp yarns. Industrial two-dimensional structure characterized by forming a long crimp on the lower surface. A textile.
In the case of a fabric using warp binding yarns, there is no additional binding yarn, so that a dense surface can be formed and no marks are generated. Further, there is no loosening of the binding yarn during use, and no internal wear occurs.
The warp binding yarns are interwoven with both the upper surface side wefts and the lower surface side wefts to form a part of the upper surface surface structure. The two warp binding yarns are alternately formed on the upper surface side surface. And weaving with different upper surface side wefts, and they cooperate to function as a single warp constituting the upper surface side surface texture. If the two warp binding yarns that are paired have a structure that passes above the same upper surface side weft, the two warp binding yarns that form the pair are on one upper surface weft. Since they are arranged in parallel, the drainage space is blocked and the drainage is changed, which may cause a mark. For the same reason, it is possible to obtain a good effect by using a structure in which each lower surface side surface is woven with another lower surface side weft.

Further, in the present invention, the portion expressed as "the upper surface side warp" shows both the upper surface side warp and the warp binding yarn that forms the upper surface side surface texture as a set. The portion expressed as “the lower surface side warp” indicates both the lower surface side warp and the warp binding yarn that forms a lower surface texture as a pair.
The warp binding yarn forming the pair is below the side where one warp binding yarn is interwoven with the upper surface side weft and the other warp binding yarn is at least one The upper warp yarn is interwoven with the lower surface side weft, and the upper warp yarn is woven with the upper surface side weft on the upper side where one warp yarn is woven with at least one lower surface weft. Assuming a combined structure and a structure in which a pair of warp binding yarns complement each other to form a structure of one warp on both the upper surface and the lower surface, weaving strength and pulling in the binding This is preferable because the structure has a good balance and has a superior surface property.
The arrangement ratio of the warp group and the binding warp group can be selected as appropriate. If the binding strength is required, the ratio of the binding warp may be increased, and the entire warp group may be used as the binding warp group. . In other cases, a large number of warp pairs may be arranged and the number of binding warp pairs may be reduced. In the case of a fabric using warp binding yarns, there is no additional binding yarn, so that a dense surface can be formed and no marks are generated. Moreover, there is no loosening of the binding yarn during use, and no internal wear occurs.

As the woven fabric structure, the lower surface is composed of three different warps, and the lower surface weft passes over the two adjacent warps, and then passes under the plurality of warps to the lower surface. The tissue that forms a long crimp. In the present invention, there are two warp yarns that form the lower surface side surface, that is, warp binding yarns that form a pair with the lower surface side warp yarn. A single warp binding yarn cannot form a suitable structure on the upper surface and the lower surface, but the upper warp and the lower surface are obtained by the cooperation of the two warp binding yarns. A structure equivalent to a side warp can be formed. In this way, three different warp structures are formed by the set of warp binding yarns and the lower surface side warp.
Further, in the present invention, “the lower surface is composed of three different warp structures” means that, for example, a structure passing through the lower side of one lower surface side weft and passing the upper side of three lower surface side wefts is repeated 3 / One warp 1 on the lower surface side of the structure and the upper side of the four lower surface side wefts, the lower side of one lower surface side weft, the upper side of the two lower surface side wefts, one lower surface side The lower side of the 4 / 1-2 / 1 structure passing under the weft and the upper side of the five lower side wefts, the lower side of one lower side weft, the lower side of one A lower surface side surface structure composed of three different structures such as a warp 3 on the lower surface side of a 5 / 1-1-1 structure passing through the upper side of the weft and passing under the lower surface side weft. The warp 1, warp 2 and warp 3 on the lower surface side here may be either the lower surface side warp or the warp binding yarn forming a pair, but preferably the warp binding yarn is the lower surface side. In order to obtain a left and right uniform structure based on the side knuckle, it is preferable that the lower surface side structure formed by the set of binding warps is a structure in which a 3/1 structure that always passes above and below the same number of lower side wefts is repeated. The lower side warp may have a 3/1 structure, a 4 / 1-2 / 1 structure, or a 5/1/1/1 structure. These are examples, and other combinations of 3/1 organization and 3 / 1-2 / 1-3 / 1-4 / 1 organization, 3/1 organization and 3 / 1-5 / 1-3 / 1-1 / There are combinations of one organization. In this way, by constituting from three different warp structures, it is possible to form a woven fabric having excellent surface properties with uniform knuckle height and the like while forming a long crimp of weft on the lower surface.

Further, the lower surface side weft has a structure in which a long crimp is formed on the lower surface side surface through the upper side of the two adjacent warps and then the lower side of the plurality of warps. Thus, by setting it as the structure | tissue which forms a weft long crimp on the lower surface side surface, it becomes a textile fabric excellent in the abrasion resistance of a weft wear type. In addition, since the two adjacent warps on the lower surface side have a structure in which one lower surface side weft is woven simultaneously, the lower surface side weft long crimp further protrudes on the surface, thereby improving the wear resistance and at the same time. Stiffness is also improved. Furthermore, on the lower surface side, two adjacent warps weave one lower surface side weft from the lower surface side, so that all the warps forming the lower surface surface are adjacent at the portion where the lower surface weft is woven from the lower surface side. The zigzag arrangement is formed while alternately approaching the warp yarns. By adopting the zigzag arrangement, the rigidity of the fabric in the oblique direction is improved, and a portion where the upper surface side warp and the lower surface side warp overlap and a portion where they do not overlap are mixed. By forming a mesh with a random size and shape, dewatering can be performed in stages, and generation of dewatering marks, penetration of sheet raw material on the wire, and loss of fibers and fillers can be suppressed.
An example of zigzag placement will be described. In the lower surface side layer in which the warp group and the binding warp group are appropriately arranged, the lower surface side wefts are woven simultaneously by two adjacent warps to form a long crimp. The two adjacent lower side warps pass simultaneously below the lower side weft. In the case of the lower surface side warps 1, 2, and 3, the warp 2 is interwoven with the adjacent warp 1 and the lower surface weft 1 '. The warp 2 is interwoven with the adjacent warp 3 and the lower side weft 7 '. Two adjacent lower side warp yarns are arranged so as to face each other at the portion interwoven with the lower side weft yarns. That is, the warp yarns 1 and 2 on the lower surface side approach each other when they are woven with the lower surface side weft yarn 1 ', and the warp yarns 2 and 3 on the lower surface side contact each other when they are woven with the lower surface side weft yarn 7'. Accordingly, the lower surface side warp 2 is closer to the warp 1 side at the intersection with the lower surface side weft 1 'and closer to the warp 3 side at the intersection with the lower surface side weft 7'. Then, the lower surface side warp 2 is zigzag arranged to meander to the right and to the left. Of course, the other lower side warp yarns have the same zigzag arrangement.

  Further, it is preferable that the warp binding yarns forming the pair have a right and left uniform structure based on the lower surface side knuckle formed through the lower side of the lower surface side weft. If both warp binding yarns have a uniform structure, the drop of the intersecting portion of the warp binding yarns becomes uniform, and the fabric has excellent surface properties. However, there are cases where the left and right sides of the design drawing do not have the same structure due to the arrangement ratio of the upper surface side wefts and the lower surface side wefts. Further, the warp binding yarns forming the pair are preferably the same structure or a mirror image structure in which the direction of the structure is changed. By setting it as such a structure, since the pull-in strength of the upper surface side weft by the warp binding yarn forming the group becomes the same, the height of the knuckle becomes uniform and the woven fabric has excellent surface properties. Moreover, the drop of the intersection part of warp binding yarn becomes uniform, and the woven fabric has excellent surface properties. However, there are cases in which the same structure does not appear on the design drawing due to the arrangement ratio of the upper surface side wefts and the lower surface side wefts as described above. When the warp binding yarn is not a left and right uniform structure based on the lower side knuckle, or when the two warp binding yarns forming the pair are different in structure, the warp binding yarn is the upper side weft The knuckle height passing through the upper side changes, and the drop in the intersection of the warp binding yarns that are paired is also different. In particular, the drop of the intersection portion is not preferable because it marks the paper. As described above, when the warp on the lower surface side is a 4 / 1-2 / 1 structure, a 3/1 structure, and a 5/1/1/1 structure, the binding warp group is 4 / 1-2 / 1. As a structure, the two warp binding yarns do not become a left and right uniform structure based on the lower side knuckle. Moreover, it is impossible for warp binding yarns forming a set to have the same structure. For this reason, it is preferable that the set of binding warps always have a repetitive structure such as a 3/1 structure passing above and below the same number of lower surface side wefts. On the other hand, the lower side warp may be a 3/1 structure, a 4 / 1-2 / 1 structure, or a 5 / 1-1 / 1 structure. As described above, in order to obtain a fabric structure having a special configuration as in the present invention, it is necessary to sufficiently consider the warp tissue and the combination thereof, the way of shifting the warp tissue, and the like.

An auxiliary weft having a smaller wire diameter than the upper surface side weft may be arranged between the upper surface side wefts on the upper surface side surface. For example, by arranging upper side wefts and auxiliary wefts alternately and forming a structure in which the auxiliary wefts form a long crimp passing over the upper side of a plurality of warps, there is an effect of improving the fiber support of the wefts.
The warp constituting the upper surface side surface structure is a warp binding yarn that forms a pair with the upper surface side warp, and these are interwoven with the upper surface side weft. The upper surface side fabric structure is not particularly limited, and other fabric structures such as plain weave, twill weave, broken twill weave and satin weave may be used. The upper surface side warp structure may be not only one type but also two types, and the upper surface side surface structure in which warps of two different structures are alternately arranged may be used. For example, there is an upper surface side surface structure in which warps forming a plain weave and warp yarns having a structure passing through the upper side of one upper surface side weft and passing the lower side of three upper surface side wefts are alternately arranged. This structure can incorporate the advantages of both tissues, such as the rigidity of plain weave structure and the permeability of 1/3 structure, and counteract both the disadvantages such as lowering the number of implants and deterioration of oblique rigidity. Can do.
The arrangement ratio of the upper surface side wefts and the lower surface side wefts may be the same or different. For example, the upper surface side weft and the lower surface side weft may be arranged at a ratio of 1: 1, or a ratio of 2: 1, 3: 2, 4: 3, or the like. In the papermaking fabric field, it is better to make the upper surface side dense from the viewpoint of fiber support, surface properties, etc., so the upper surface side weft ratio should be increased.
The wire diameter is not particularly limited, but in order to obtain a dense and smooth surface, it is preferable that the upper surface side weft and the upper surface side warp constituting the upper surface side have relatively small wire diameters. And in the use which attaches great importance to surface properties, it is preferable to use a warp binding yarn having the same diameter as the upper surface side warp. If there is a difference in wire diameter between the upper surface side warp and warp binding yarn, the larger diameter thread will protrude on the upper surface or lower surface, giving a wire mark to the paper, or by cutting with wear. May end up. If the upper surface side warp and the warp binding yarn have the same wire diameter, the height of the upper surface side warp knuckle will be approximately the same, so that a relatively uniform surface can be formed. In addition, if the wire diameters of the lower surface side warp and the warp binding yarn are the same, it is preferable in an application where wear resistance is required, but it is not preferable in a field where surface properties are required.

  Since the lower surface on the machine or roll contact surface side requires rigidity and wear resistance, it is preferable that the lower surface side weft and the lower surface side warp have a relatively large wire diameter. In the papermaking fabric field, the upper surface side warp and the warp binding yarn have the same wire diameter, and the lower surface side warp and the lower surface side weft have a larger diameter than that of the surface and wear resistance. The fabric can satisfy both requirements. In that case, there is a risk of wear in the portion where the warp binding yarn passes under the lower side weft, since the warp binding yarn having a small wire diameter appears on the lower surface, but there is a concern about wear. A structure in which warp pairs are arranged on both sides of a set of warp yarns, and the warp binding yarns are arranged adjacent to each other on the lower side of the lower surface side wefts, and the lower surface side warp also passes below the lower surface side wefts. Then, the warp binding yarn with a small wire diameter is not worn and cut before the lower side warp with a large wire diameter, and the fabric cannot be used due to the breakage of the warp binding yarn. Absent.

  The lower surface of the present invention is composed of three different types of warp structures on the lower surface side, and the weft structure passes through the upper side of two adjacent warp yarns, and then passes under the plurality of warp yarns. A structure that forms a long crimp on the lower surface is used. In order to make such a structure, it is necessary to fully examine the structure of the three types of warp on the lower surface side and its arrangement, even if the arrangement ratio is alternating one or two, What is necessary is just to arrange | position each in the ratio of one to several. Preferably, the warp binding yarns that are formed on both sides of the lower surface side knuckle are formed with the warp binding yarns passing through the lower side of the lower surface side wefts. Good. Which warp tissue group is used as the binding warp group may be considered in consideration of these conditions.

The yarn used in the present invention may be selected depending on the application. For example, in addition to monofilament, multifilament, spun yarn, crimped processing, bulky processing, etc., generally textured yarn, bulky yarn, stretch yarn, etc. Processed yarns that are called, or yarns that are combined by twisting them 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. The material of the yarn can also be freely selected, and polyester, polyamide, 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.
Generally, as the papermaking wire, it is preferable to use a polyester monofilament having rigidity and excellent dimensional stability for the upper surface side warp, the lower surface side warp, the warp binding yarn, and the upper surface side weft. In addition, it is preferable to interweave polyester monofilaments and polyamide monofilaments alternately on the lower surface side wefts that require wear resistance so that the wear resistance can be improved while ensuring rigidity.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings.
FIGS. 1-21 is an Example of this invention, Comprising: The design drawing, sectional drawing along warp, and sectional drawing along weft are shown. 22 and 23 are conventional examples, FIG. 22 is a design diagram of the conventional example, and FIG. 23 is a cross-sectional view taken along the warp of FIG.
The design drawing is the smallest repeating unit of the fabric structure, and this complete structure is connected vertically and horizontally to form the entire fabric structure. In the design drawing, warps are indicated by Arabic numerals, for example, 1, 2, and 3. Of these, in the case of a set of warps composed of upper surface side warp and lower surface side warp, and in a binding warp composed of two warp binding yarns There may be a pair. The wefts are indicated by Arabic numerals with dashes, for example, 1 ', 2', 3 ', and the upper surface side wefts and the lower surface side wefts may be arranged vertically depending on the arrangement ratio, or only the upper surface side wefts.
Further, a cross indicates that the upper surface side warp is positioned above the upper surface side weft, and a Δ indicates that the lower surface side warp is positioned below the lower surface side weft. The asterisk indicates that the warp ground yarn is located above the upper surface side weft, and the ◇ symbol indicates that the warp yarn is located below the lower surface side weft. The ● mark also indicates that the warp binding yarn is located above the upper surface side weft, and the ○ mark indicates that the warp binding yarn is located below the lower surface weft. . Also, in the cross-sectional view along the warp and weft, the warp binding yarns marked with ◆ ◇ on the design drawing are painted with dots to distinguish the paired warp binding yarns. Warp binding yarns are filled with diagonal lines.
The upper surface side warp and the lower surface side warp, and the upper surface side weft and the lower surface side weft are arranged one above the other. As for the wefts, there are some places where the lower surface side wefts are not arranged below the upper surface side wefts from the arrangement ratio.
In the design drawing, the yarns are arranged so as to be accurately overlapped vertically, but this is for the convenience of the drawing and may be displaced in an actual fabric. Further, the two warp binding yarns forming the pair stick to each other and function as one warp constituting the upper surface side complete structure on the upper surface side surface. The same applies to the lower side fabric.

(Comparative Example 1)
FIG. 22 is a design diagram of the fabric of Comparative Example 1. FIG. 23 shows a cross-sectional view of the warp group 1 and the binding warp group 2 in the design diagram of FIG. This fabric is a 20-shaft two-layer fabric in which a set of binding warps is arranged at a ratio of 2/10, and the arrangement ratio of the upper surface side weft and the lower surface side weft is 1: 1.
In the design diagram of FIG. 22, 2 and 7 are sets of binding warps composed of two warp binding yarns, 1, 3, 4, 5, 6, 8, 9, and 10 are upper surface side warps, It is a set of warps composed of lower surface side warps.
The lower surface texture is composed of one type of warp, and the lower surface warps are above the six lower surface side wefts, below the one lower surface side weft, above the two lower surface side wefts, and one lower surface side 6 / 1-2 / 1 structure passing under the weft. For the purpose of improving wear resistance, the lower surface side surface has a structure in which the lower surface side weft passes over the two lower surface side warps and then passes under the eight lower surface side warps. This fabric can form a lower side weft long crimp, but the structure of warp binding yarns forming a pair is equal to the left and right side of the lower side knuckle formed through the lower side of the lower side weft, and the same It cannot be organized. Even if one can be a left-right equal organization, the other is not a left-right equal organization. Therefore, the knuckle height formed through the upper side of the upper surface side wefts is different, of course, the drop heights of the intersections of the two warp binding yarns are also sparse, and the woven fabric has a strong wire mark. End up. The drop in the intersection particularly marks the paper.
As shown in FIG. 23, which shows a cross-sectional view along the warp of Comparative Example 1, both the warp binding yarns 2A and 2B have a left and right uniform structure based on the lower surface side knuckle passing through the lower side of the lower surface side weft. is not. In the warp binding yarn 2A, the lower surface side weft 8'd passes below the upper surface side weft 1'u, above 2'u, below 3'u, above 4'u and then toward the lower surface side. The structure passes through the lower side and passes through the upper side of the upper surface side weft 10'u toward the upper side. That is, on the basis of the lower surface side weft 8'd, one side passes between the three upper surface side wefts 7'u, 6'u, 5'u and the lower surface side wefts 7'd, 6'd, 5'd, Next, the structure passes through the upper side of the upper surface side weft 4'u, and on the opposite side, after passing under the lower surface side weft 8'd, one upper surface side weft 9'u and lower surface side weft 9'd Since it is a structure that passes between and then passes through the upper side of the upper surface side weft 10'u, it cannot be said to be a left-right uniform structure. Also, in the warp binding yarn 2B, after passing below the lower surface side weft 1'd, the upper surface side weft 6'u, above the upper surface side weft 6'u, below 7'u, and above 8'u Street, then down the organization. That is, four upper surface side wefts 2'u, 3'u, 4'u, 5'u and lower surface side wefts 2'd, 3'd, 4'd on one side with respect to the lower surface side weft 1'd, 5'd, and then passes the upper side of the upper surface side weft 6'u. On the opposite side, after passing through the lower side of the lower surface side weft 1'd, the two upper surface side wefts 10'u , 9′u and the lower surface side wefts 10′d, 9′d, and then the upper surface side wefts 8′u. Similarly, the warp binding yarn 2B is not a right and left uniform structure. In addition, the warp binding yarns 2A and 2B are not the same structure, and the knuckle heights are different, and the drop heights of the intersections are also different.
On the surface on the upper surface side of Comparative Example 1 as described above, a fabric with few marks and excellent surface properties cannot be expected. Based on this, the example will be confirmed.

Example 1
FIG. 1 is a design diagram of a fabric of Example 1 of the present invention. FIG. 2 is a cross-sectional view of the warp group 1, the binding warp group 2, and the warp group 3 in the design diagram of FIG. FIG. 3 is a cross-sectional view along the weft 1 'in which the upper surface side weft and the lower surface side weft are arranged vertically in the design diagram of FIG. This fabric is a 16-shaft two-layer fabric in which a set of binding warps is arranged at a ratio of 4/8, and the lower surface texture is composed of three different warps, and the upper surface texture is two different warps. Consists of. The arrangement ratio of the upper surface side weft and the lower surface side weft is 3: 2.
In the design diagram of FIG. 1, 2, 4, 6, and 8 are sets of binding warps composed of two warp binding yarns, and 1, 3, 5, and 7 are upper surface side warps and lower surface side warps. It is a set of warp.
The warp binding yarns forming the pair are such that when one warp binding yarn is interwoven with the upper surface side weft to form the upper surface surface texture, the other warp binding yarn is at least The lower surface side surface texture is formed by interweaving with one lower surface side weft. That is, in the portion where one warp binding yarn forms the lower surface structure, the other warp binding yarn complements the upper surface structure, and one warp binding yarn is the upper surface. In the portion forming the side surface texture, the other warp binding yarn complements the lower surface texture. In this way, the two warp binding yarns complement each other to form a top surface structure and a bottom surface structure.
The lower surface is composed of three different warps. The lower surface warps 1, 5 are above five lower surface wefts, below one lower surface weft, above one lower surface weft, one 5 / 1-1 / 1 structure passing under the lower surface side wefts, and warp threads 2, 4, 6, 8 on the lower surface side are structures passing over the three lower surface side wefts and under one lower surface side weft. The warp yarns 3 and 7 on the lower surface side are above four lower surface side wefts, below one lower surface side weft, above two lower surface side wefts, and one lower surface side. It is a 4 / 1-2 / 1 structure that passes under the weft. Here, warps 2, 4, 6, and 8 are a set of binding warps, but by forming two pairs, it functions as one lower surface side warp and forms a structure like other lower surface side warps. Yes. And the lower surface side weft has a structure in which a long crimp of the weft thread is formed on the lower surface side surface through the upper side of the adjacent two lower surface side warps and then the lower side of the six continuous lower surface side warps. . By forming a structure in which weft long crimps are formed on the lower surface, the fabric is excellent in abrasion resistance. In addition, the lower side wefts are woven from the lower side by two adjacent warps, and the rigidity is improved. Further, the long crimp protrudes from the lower side surface and the wear resistance volume is increased, resulting in excellent wear resistance. .
The upper side surface has two different warps arranged alternately, and the upper side warps 1, 3, 5, and 7 have a structure passing over one upper side weft and under one upper side weft. It is a repeated 1/1 structure, and the upper side warp yarns 2, 4, 6, 8 are 2/2 structures in which a structure passing over two upper surface side wefts and passing under two upper surface side wefts is repeated. . Like the lower surface side structure, warps 2, 4, 6, and 8 are a set of binding warp yarns, but function as one upper surface side warp and form a structure in the same manner as the other upper surface side warps.

In this embodiment, the warp binding yarns forming the pair are of different structures, and when the sectional view of the warp binding yarn 2 in FIG. 2 is seen, 2A is the upper surface side weft 1 Passes under 'u, 2'u, passes over the upper surface side wefts 3'u, 4'u, then goes to the lower surface side, passes under the lower surface side weft yarn 7'd, and then upwards to the upper surface side The structure passes through the upper side of the wefts 11'u and 12'u. The other warp binding yarn 2B passes through the lower side of the lower surface side weft 1'd and goes upward, passes over the upper surface side wefts 7'u and 8'u, and then goes to the lower surface side. It is. These are different structures, but when combined, a 2/2 structure is formed on the upper surface and a 3/1 structure is formed on the lower surface. In addition, the warp binding yarns 2A and 2B have a left and right uniform structure based on the lower side knuckle. Since the arrangement ratio of the upper surface side wefts and the lower surface side wefts is 3: 2, the left and right are not even at all, but the lower surface side wefts 7'd may be shifted to the 8'd side in terms of the fabric structure, and substantially substantially An equal organization. By making the warp binding yarns forming the pair into a left and right uniform structure in this way, the height of the knuckle on the upper surface side surface of the warp binding yarns forming the pair and the drop of the intersection are made uniform. be able to. In other words, when the left and right uniform structures are based on the lower surface side knuckle as in this embodiment, the warp binding yarn 2A draws the upper surface side wefts 3'u and 4'u into the lower surface side, and the upper surface side weft 11 The heights of the portions that pull 'u and 12'u to the lower surface side are the same. Further, since the other warp binding yarn 2B has a left and right uniform structure with respect to the lower surface side knuckle, a portion for drawing the upper surface side wefts 7'u and 8'u to the lower surface side, and the next cycle The heights of the portions where the upper surface side wefts 7'u and 8'u are drawn to the lower surface side are the same. As a result, the drop formed at the intersection of the warp binding yarns 2A and 2B between the wefts 5'u and 6'u and between 9'u and 10'u becomes uniform, so that the entire woven fabric A woven fabric having excellent surface uniformity can be obtained.
Further, by arranging the warp pairs on both sides of the binding warp group, it is possible to reduce wear on the lower surface side of the warp binding yarn having a relatively small wire diameter. The warp forming the lower surface side surface is a lower surface side warp and warp binding yarn, and two adjacent warps on the lower surface side pass under the same lower surface side weft. In the present embodiment, when the design drawing is viewed, the lower surface side warp and the warp binding yarn both have two lower surface side knuckles passing through the lower side of the lower surface side weft. When the lower surface side is the machine contact surface side, the lower surface side warp has a large wire diameter, so it is relatively difficult to wear and cut even when contacting the machine or roll. However, the lower surface side knuckle of the small diameter warp binding yarn may come into contact with the machine or roll and become worn and cut, making it unusable.
However, as in this embodiment, when the warp binding yarn is disposed adjacent to the lower side weft under the lower side weft, the lower side warp also has a structure that passes under the lower side weft. The small warp binding yarn is not worn and cut before the lower side warp having a large wire diameter, and the fabric cannot be used due to the breakage of the warp binding yarn. Specifically, when the warp binding yarn has a smaller diameter than the lower surface side warp, when viewed with this single thread, the warp binding yarn 2A passes under the lower surface side weft 7'd, Since the warp binding yarn 2A is present on the lower surface side surface closest to the roll side, it is easily abraded by a roll or the like. However, the lower surface side knuckle passes below the lower surface side weft 7'd while the lower surface side warp 3b passes the lower surface side knuckle next to the lower surface side weft 7'd. By forming the structure to be formed, the warp binding yarn 2A and the lower surface side warp 3b that are substantially adjacent to each other pass through the lower side of the lower surface side weft 7'd. Even with the small diameter warp binding yarn 2A, it becomes difficult to wear and cut.
Similarly, the warp binding yarn 2B is adjacent to the lower surface side knuckle passing through the lower side of the lower surface side weft 1'd, and the adjacent warp yarn 1b is connected to the lower surface side knuckle passing under the lower surface side weft 1'd. By forming the structure to be formed, the warp binding yarn 2B and the lower surface side warp thread 1b which are arranged substantially adjacent to each other pass through the lower side of the lower surface side weft thread 1'd. Even with the yarn 2B, it is difficult to wear and cut, and the fabric is not broken in a short period of time. In this way, a woven fabric having excellent wear resistance is obtained by arranging the warp pairs on both sides of the binding warp group.
Further, on the lower surface side, two adjacent warps weave one lower surface side weft from the lower surface side, whereby the lower surface side weft forms a weft long crimp for multiple warp yarns on the lower surface side, It is preferable that all the warps forming the lower surface have a zigzag arrangement in which the left and right warps are alternately approached at the portion where the lower surface weft is woven from the lower surface.

In the zigzag arrangement, one lower surface side warp is formed adjacent to the left side after forming a knuckle under the lower surface side weft same as the lower surface side warp where the lower surface side warp is disposed adjacent to the right side. A structure in which a knuckle is formed under the lower surface side weft same as the lower surface side warp, and one warp alternately leans against the right and left wefts. By adopting the zigzag arrangement, the rigidity of the fabric in the oblique direction is improved, and a portion where the upper surface side warp and the lower surface side warp overlap and a portion where they do not overlap are mixed. By forming a mesh with a random size and shape, dewatering can be performed in stages, and generation of dewatering marks, penetration of sheet raw material on the wire, and loss of fibers and fillers can be suppressed.
For example, in the lower surface side warp 3, a knuckle is formed on the lower side of the lower surface side weft 2'd simultaneously with the warp binding yarn 4 adjacent to the right side, and then adjacent to the left side. At the same time as the warp binding yarn 2, a knuckle is formed on the lower side of the lower surface side weft 7'd. Then, the lower surface side warp 3 is shifted to the right side at the intersection with the lower surface side weft 3'd and is shifted to the left side at the intersection with the lower surface side weft 7'd. It becomes. Since the upper surface side warp and warp binding yarn do not form the same zigzag arrangement as the lower surface side warp on the upper surface, the upper and lower warps overlap in some parts and the upper and lower warps do not overlap in some parts. The shape of the dewatering hole penetrating from the upper side to the lower side is also random, so that partial rapid dehydration can be suppressed. Although only the lower surface side warp 3 has been described above, the other lower surface side warps and warp binding yarns have the same random structure, and the same surface property can be obtained as a whole fabric.

(Example 2)
FIG. 4 is a design diagram of the fabric of Example 2 of the present invention. FIG. 5 shows a cross-sectional view of the warp group 1, the binding warp group 2, and the warp group 3 in the design diagram of FIG. In Example 1, there are two types of structures forming the upper surface side surface structure, the upper surface side warps 1, 3, 5, 7 are 1/1 structures, and the upper surface side warps 2, 4, 6, 8 are 2/2. In this embodiment, this was replaced, and the warp 1, 3, 5, 7 on the upper surface side had a 2/2 structure, and the warp 2, 4, 6, 8 on the upper surface side had 1 / 1 It was set as the structure | tissue which forms a structure | tissue. Thus, in this example, the set of binding warp yarns is a structure that forms a 1/1 structure on the upper surface. Other conditions are the same.
The lower surface of the present embodiment is composed of three different warps. The lower surface warps 1 and 5 are above the five lower surface wefts, below the one lower surface weft and above the one lower surface weft. It is a 5 / 1-1 / 1 structure that passes under one lower surface side weft. The lower surface side warps 2, 4, 6, and 8 are the upper surface of three lower surface side wefts and one lower surface side weft. The warp yarns 3 and 7 on the lower surface side are above the four lower surface side wefts, below the one lower surface side weft, above the two lower surface side wefts, It is a 4 / 1-2 / 1 structure passing under the lower surface side weft of the book. Here, warps 2, 4, 6, and 8 are a set of binding warps, but by forming two pairs, it functions as one lower surface side warp and forms a structure like other lower surface side warps. Yes. And the lower surface side weft has a structure in which a long crimp of the weft thread is formed on the lower surface side surface through the upper side of the adjacent two lower surface side warps and then the lower side of the six continuous lower surface side warps. . By forming a structure in which weft long crimps are formed on the lower surface, the fabric is excellent in abrasion resistance. In addition, the lower side wefts are woven from the lower side by two adjacent warps, and the rigidity is improved. Further, the long crimp protrudes from the lower side surface and the wear resistance volume is increased, resulting in excellent wear resistance. .

The upper surface is formed by alternately arranging two different warps. Upper surface warps 1, 3, 5, and 7 are formed by passing a structure passing over two upper surface wefts and under two upper surface wefts. Repetitive 2/2 structure, warp 2, 4, 6, 8 on the upper surface side is a 1/1 structure that repeats the structure passing over one upper surface side weft and under one upper surface side weft. . In this way, the binding warp group may be a structure that forms a 1/1 plain weave structure on the upper surface side surface. Further, in this embodiment, the warp binding yarns forming the pair have the same structure, and when the cross-sectional view of the warp binding yarn 2 in FIG. 5 is seen, 2A is the upper side of the upper weft 1'u. 2'u, 3'u, then lower side, lower side weft 7'd, and upper side weft 11'u, 12'u It is an organization that passes below. Further, the other warp binding yarn 2B passes through the lower side of the lower surface side weft 1'd to the upper side, above the upper surface side weft 5'u, below 6'u, above 7'u, The structure passes under 8'u, 9'u, and then toward the lower surface. These are structures that pass through the lower side of one lower surface side weft after forming three knuckles that pass above the upper surface side weft, and are the same as each other. A 3/1 structure is formed on the tissue and the lower surface. In addition, the warp binding yarns 2A and 2B have a left and right uniform structure based on the lower side knuckle. Since the arrangement ratio of the upper surface side wefts and the lower surface side wefts is 3: 2, the left and right are not even at all, but the lower surface side wefts 7'd may be shifted to the 8'd side in terms of the fabric structure, and substantially substantially An equal organization. In this way, the warp binding yarns forming the pair are made to have the same left and right structure and the same structure, respectively, so that the height of the knuckle on the upper surface side surface of the warp binding yarns forming the pair, The depression can be made uniform. That is, as in the present embodiment, when the left and right uniform structures are based on the lower surface side knuckle and the two are the same structure, the warp binding yarn 2A draws the upper surface side weft 3'u to the lower surface side, and the upper surface The height of the portion where the side weft 11'u is drawn to the lower surface side is the same. In the other warp binding yarn 2B, the portion where the upper surface side weft 5'u is drawn to the lower surface side and the upper surface side weft 9 ' The warp binding yarn 2A having the same height at the portion where u is pulled to the lower surface side, and between the upper surface side wefts 3'u and 4'u and between 9'u and 10'u Since the depression that can be made at the intersection of 2B is also uniform, it is possible to obtain a woven fabric having excellent uniformity as a whole.
Then, the warp on the lower surface side was arranged in a zigzag manner. As a result, the fabric's diagonal rigidity is improved, and the upper side warp and the lower side warp overlap and the non-overlapping parts coexist. It is possible to suppress the generation of dehydration marks, the penetration of sheet raw material on the wire, and the loss of fibers and fillers.

FIG. 6 is a design diagram of the fabric of Example 3 of the present invention. FIG. 7 is a cross-sectional view of the warp group 1, the binding warp group 2, and the warp group 3 in the design diagram of FIG. In Examples 1 and 2, there were two types of structures forming the upper surface side surface structure, but in this example, one type was used, and all the upper surface side warps were 1/1 structures. Thereby, the set of the binding warps of this example was a structure that formed a 1/1 structure on the upper surface. Other conditions are the same.
The lower surface of the present embodiment is composed of three different warps. The lower surface warps 1 and 5 are above the five lower surface wefts, below the one lower surface weft and above the one lower surface weft. It is a 5 / 1-1 / 1 structure that passes under one lower surface side weft. The lower surface side warps 2, 4, 6, and 8 are the three lower surface side wefts above the one lower surface side weft. The warp yarns 3 and 7 on the lower surface side are above the four lower surface side wefts, below the one lower surface side weft, above the two lower surface side wefts, It is a 4 / 1-2 / 1 structure passing under the lower surface side weft of the book. Here, warps 2, 4, 6, and 8 are a set of binding warps, but by forming two pairs, it functions as one lower surface side warp and forms a structure like other lower surface side warps. Yes. And the lower surface side weft has a structure in which a long crimp of the weft thread is formed on the lower surface side surface through the upper side of the adjacent two lower surface side warps and then the lower side of the six continuous lower surface side warps. . By forming a structure in which weft long crimps are formed on the lower surface, the fabric is excellent in abrasion resistance. In addition, the lower side wefts are woven from the lower side by two adjacent warps, and the rigidity is improved. Further, the long crimp protrudes from the lower side surface and the wear resistance volume is increased, resulting in excellent wear resistance. .
The upper surface is composed of one type of warp structure, and all upper surface warps have a 1/1 structure in which a structure passing over one upper surface side weft and under one upper surface weft is repeated.
Further, in this embodiment, the warp binding yarn has a left and right uniform structure with reference to the lower surface side knuckle. In this way, the warp binding yarns forming the pair have a uniform structure on the left and right sides, so that the drop of the intersection of the warp binding yarns forming the pair can be made uniform, and the overall woven fabric is excellent in uniformity. Woven fabric.
Then, the warp on the lower surface side was arranged in a zigzag manner. As a result, the fabric's diagonal rigidity is improved, and the upper side warp and the lower side warp overlap and the non-overlapping parts coexist. It is possible to suppress the generation of dehydration marks, the penetration of sheet raw material on the wire, and the loss of fibers and fillers.

Example 4
FIG. 8 is a design diagram of the fabric of Example 4 of the present invention. FIG. 9 is a cross-sectional view of the binding warp sets 1, 2, and 3 in the design diagram of FIG. There are two types of warp structures on the upper surface side, and the warp threads on the upper surface side were alternately arranged in a 1/1 structure and a 2/2 structure. In this example, all warp pairs are made into a set of binding warps, and the fabric is excellent in binding strength.
The lower surface of the present embodiment is composed of three different warps. The lower surface warps 1 and 5 are above the five lower surface wefts, below the one lower surface weft and above the one lower surface weft. It is a 5 / 1-1 / 1 structure that passes under one lower surface side weft. The lower surface side warps 2, 4, 6, and 8 are the upper surface of three lower surface side wefts and one lower surface side weft. The warp yarns 3 and 7 on the lower surface side are above the four lower surface side wefts, below the one lower surface side weft, above the two lower surface side wefts, It is a 4 / 1-2 / 1 structure passing under the lower surface side weft of the book. Here, the warps 1 to 8 are a set of binding warps, but by forming two pairs, they function as one lower surface side warp and form a structure in the same manner as the lower surface side warp. And the lower surface side weft has a structure in which a long crimp of the weft thread is formed on the lower surface side surface through the upper side of the adjacent two lower surface side warps and then the lower side of the six continuous lower surface side warps. . By forming a structure in which weft long crimps are formed on the lower surface, the fabric is excellent in abrasion resistance. In addition, the lower side wefts are woven from the lower side by two adjacent warps, and the rigidity is improved. Further, the long crimp protrudes from the lower side surface and the wear resistance volume is increased, resulting in excellent wear resistance. .
The upper surface is composed of two types of warp structures. The warp on the upper surface side is composed of 2/2 textures in which a structure passing through two upper surface side wefts and two lower surface side wefts is repeated. The 1/1 structure which repeated the structure | tissue which passes the lower side of one upper surface side weft was arrange | positioned alternately on the upper surface side weft.
In this embodiment, the warp binding yarns have a left and right uniform structure with reference to the lower surface side knuckle, and the warp binding yarns forming the set have the same structure.

Then, the warp on the lower surface side was arranged in a zigzag manner. As a result, the fabric's diagonal rigidity is improved, and the upper side warp and the lower side warp overlap and the non-overlapping parts coexist. It is possible to suppress the generation of dehydration marks, the penetration of sheet raw material on the wire, and the loss of fibers and fillers.

(Example 5)
FIG. 10 is a design diagram of a fabric according to Example 5 of the present invention. FIG. 11 is a sectional view of the warp group 1 and the binding warp group 2 in the design diagram of FIG. This fabric is a 16-shaft two-layer fabric in which a set of binding warps is arranged at a ratio of 1/8, and the lower surface texture is composed of three different warps, and the upper surface and lower surface wefts are disposed. Is 1: 1.
In the design diagram of FIG. 10, 2 is a set of binding warps composed of two warp binding yarns, and 1, 3, 4, 5, 6, 7, and 8 are upper surface side warps and lower surface side warps. It is a set of warp. A set of binding warps that interweave the upper and lower layers is arranged at a ratio of 1/8, but even at this level, the binding strength is sufficient.
The warp binding yarns forming the pair are such that when one warp binding yarn is interwoven with the upper surface side weft to form the upper surface surface texture, the other warp binding yarn is at least The lower surface side surface texture is formed by interweaving with one lower surface side weft. That is, in the portion where one warp binding yarn forms the lower surface structure, the other warp binding yarn complements the upper surface structure, and one warp binding yarn is the upper surface. In the portion forming the side surface texture, the other warp binding yarn complements the lower surface texture. In this way, the two warp binding yarns complement each other to form a top surface structure and a bottom surface structure.
The lower surface is composed of three different warps. The lower surface warps 1, 5 are above five lower surface wefts, below one lower surface weft, above one lower surface weft, one 5 / 1-1 / 1 structure passing under the lower surface side wefts, and warp threads 2, 4, 6, 8 on the lower surface side are structures passing over the three lower surface side wefts and under one lower surface side weft. The warp yarns 3 and 7 on the lower surface side are above four lower surface side wefts, below one lower surface side weft, above two lower surface side wefts, and one lower surface side. It is a 4 / 1-2 / 1 structure that passes under the weft. Here, the warp 2 is a set of binding warps, but by forming two pairs, it functions as one lower surface side warp and forms a structure like the other lower surface side warps. And the lower surface side weft has a structure in which a long crimp of the weft thread is formed on the lower surface side surface through the upper side of the adjacent two lower surface side warps and then the lower side of the six continuous lower surface side warps. . By forming a structure in which weft long crimps are formed on the lower surface, the fabric is excellent in abrasion resistance. In addition, the lower side wefts are woven from the lower side by two adjacent warps, and the rigidity is improved. Further, the long crimp protrudes from the lower side surface and the wear resistance volume is increased, resulting in excellent wear resistance. .

The upper surface side surface is a 1/1 structure obtained by repeating a warp structure passing over one upper surface side weft and under one upper surface side weft. The warp 2 is a set of binding warps, but functions as one upper surface side warp and forms a structure in the same manner as the other upper surface side warps.
The warp binding yarns forming a pair in this example have the same structure. When the cross-sectional view of the warp binding yarn 2 in FIG. 11 is viewed, 2A is below the upper surface side weft 1'u, 2 ' The structure passes above u, then toward the lower surface, passes below the lower surface side weft 5'd, and passes upward to the upper side of the upper surface side weft 8'u. Further, the other warp binding yarn 2B passes through the lower side of the lower surface side weft 1'd and moves upward, on the upper surface side weft 4'u, below 5'u and above 6'u. It is an organization that goes to the lower surface side. By combining these, a 1/1 structure is formed on the upper surface and a 3/1 structure is formed on the lower surface. In addition, the warp binding yarns 2A and 2B have a left and right uniform structure based on the lower side knuckle. Thus, by making the warp binding yarns forming the pair into a right and left uniform structure, the drop of the intersection of the warp binding yarns forming the pair can be made uniform. That is, when the left and right uniform structures are used with reference to the lower surface side knuckle as in this embodiment, the warp binding yarn 2A draws the upper surface side weft 2'u to the lower surface side and the upper surface side weft 8'u to the lower surface side. The height of the part pulled in to the side becomes the same. Further, since the other warp binding yarn 2B has a left and right uniform structure with respect to the lower surface side knuckle, the portion for drawing the upper surface side weft 4'u to the lower surface side and the upper surface side weft 6'u The height of the part drawn in to the lower surface side is the same. As a result, the drop formed at the intersection of the warp binding yarns 2A and 2B between the weft yarns 2'u and 3'u and between 7'u and 8'u becomes uniform. A woven fabric excellent in uniformity can be obtained.
Further, by arranging the warp pairs on both sides of the binding warp group, it is possible to reduce wear on the lower surface side of the warp binding yarn having a relatively small wire diameter.
Then, the warp on the lower surface side was arranged in a zigzag manner. As a result, the fabric's diagonal rigidity is improved, and the upper side warp and the lower side warp overlap and the non-overlapping parts coexist. It is possible to suppress the generation of dehydration marks, the penetration of sheet raw material on the wire, and the loss of fibers and fillers.

Is 1: 1.
In the design diagram of FIG. 12, 2 is a set of binding warps composed of two warp binding yarns, and 1, 3, 4, 5, 6, 7, and 8 are upper surface side warps and lower surface side warps. It is a set of warp. A set of binding warps that interweave the upper and lower layers is arranged at a ratio of 1/8, but even at this level, the binding strength is sufficient.
The warp binding yarns forming the pair are such that when one warp binding yarn is interwoven with the upper surface side weft to form the upper surface surface texture, the other warp binding yarn is at least The lower surface side surface texture is formed by interweaving with one lower surface side weft. That is, in the portion where one warp binding yarn forms the lower surface structure, the other warp binding yarn complements the upper surface structure, and one warp binding yarn is the upper surface. In the portion forming the side surface texture, the other warp binding yarn complements the lower surface texture.

The warp binding yarn 2A passes under the upper surface side weft 1'u, passes over 2'u, goes downward, passes under the lower surface side weft 5'd, and goes upward. 8′u, 9′u, 10′u, upper side, lower side weft 13′d, lower side upper weft 16′u, upper side It becomes an organization that passes through.

Thus, by making the warp binding yarns forming the pair into a left-right uniform structure or a mirror image structure, it is possible to make the drop of the intersection of the warp binding yarns forming the pair uniform.
Further, by arranging the warp pairs on both sides of the binding warp group, it is possible to reduce wear on the lower surface side of the warp binding yarn having a relatively small wire diameter. When the lower surface side warp adjacent to the lower surface side weft passes below the lower surface side weft as in the present embodiment, the lower surface side warp also passes below the lower surface side weft. The ground yarn binding yarn is not worn and cut before the lower side warp having a large wire diameter, and the fabric is not unusable due to the breakage of the warp binding yarn.
In addition, on the lower surface side, when two adjacent warps have a structure in which one lower surface side weft is simultaneously woven from the lower surface side, the lower surface side weft forms a plurality of warp long crimps on the lower surface. At the same time, it is preferable that the warp forming the lower surface side has a zigzag structure with the adjacent left and right warps alternately.
The zigzag arrangement improves the diagonal rigidity of the fabric, and the upper side warp and the lower side warp overlap and the non-overlapping parts coexist. It is possible to suppress generation of dehydration marks, penetration of sheet raw material on the wire, and loss of fibers, fillers, and the like.
