BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to industrial fabrics such as paper fabrics, conveyor belts and filter cloths.

[0002]

2. Description of the Related Art Conventionally, as a woven fabric for industrial use, a woven fabric made of warp and weft has been widely used. For example, it is used in many other fields such as a wire for papermaking, a conveyor belt and a filter cloth. Textile properties suitable for the environment of use and usage are required. In particular, the demands on papermaking wires used in the paper manufacturing process where the raw material is dehydrated by utilizing the mesh of the fabric are strict, and the fabric with excellent surface properties that does not transfer the wire mark of the fabric to the paper There is a demand for a woven fabric that has a rigidity that can be suitably used even under various environments, and that can maintain the conditions necessary for producing good paper for a long period of time. In addition, fiber support, improved yield of papermaking, good drainage, abrasion resistance,
Dimensional stability and running stability are required. Further, in recent years, the speed of papermaking machines has increased, and accordingly, the demand for papermaking wires has become more severe. As described above, the requirements for most industrial fabrics and their solutions can be understood by describing the demanding papermaking fabrics among the industrial fabrics. Therefore, the present invention will be described below on behalf of the papermaking fabrics. For example, if the papermaking speed becomes high, the dehydration speed inevitably becomes high, and it is necessary to increase the dehydration power. As a result, the fibers, fillers, etc. are naturally removed and wire marks are significantly generated, so that it is necessary to further improve the fiber supportability and surface property. In addition, when the wet paper web is deeply caught in the papermaking fabric or the fibers are squeezed into the paper fabric, there arises a problem that the wet paper web releasability is deteriorated when the wet paper web is transferred to the felt. The wet paper that remains on the fabric is pressed against the surface of the fabric by the dehydration force, so it is difficult for the wet paper to be present in the areas where the threads are present, and conversely, the wet paper is a mesh between the meshes where no threads are present. This is because it is difficult to insert the threads and generate a mesh mark on the surface of the wet paper. It is impossible to completely eliminate the wire mark, but in order to make it as small as possible and inconspicuous, it is necessary to make the upper surface of the woven fabric fine so as to improve the surface smoothness and the fiber supporting property. However, finely woven fabrics that place importance on surface properties and fiber support properties are basically inferior in wear resistance because they are woven with threads having a small wire diameter. Further, since the papermaking fabric travels at a high speed, there is a phenomenon that the fabric gradually wears due to friction with a roll or the like on the running surface side that is in contact with the machine, and the wear may cause the service life to expire. In order to improve wear resistance, various measures are required, such as changing the woven structure to a weft-wear type structure or changing the material of the yarn. Especially, by using a yarn with a large wire diameter, wear resistance is imparted. The method of doing 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. In order to solve the problems of both surface property and wear resistance, two fabrics composed of different warp and weft yarns are used for the upper layer and the running layer, respectively, Two-ply fabrics have been used that are united by yarn ties. This method has an effect that a woven fabric can be adopted according to the performance required for each. A dense upper layer surface was formed by using warp yarns and weft yarns having a small wire diameter in the upper surface side layer, and a running surface having large wear resistance was formed by using warp yarns and weft yarns having a large wire diameter in the running surface side layer. As the binding yarn, a yarn having a smaller diameter than the upper surface side warp and the upper surface side weft is generally used so as not to deteriorate the surface property. A plain weave is often used to form a dense surface in the upper side layer design, but since a binding yarn is actually used to interweave two layers, the binding yarn is substantially attached to the plain weave surface. Surfaces arranged in places will be formed. Since the binding yarn also has a portion that appears on the surface as described above, it is not preferable to use a yarn having a too large wire diameter because of the problem of surface smoothness. In addition, usually, the papermaking fabric is often tensioned in the warp direction during use, and the warp yarn is always in tension, so that the warp yarn hardly loosens and moves when the fabric is running. However, due to problems such as weavability and fiber supportability, the binding yarn that is often placed between the wefts stretches when tension is applied, or the binding yarn is rubbed between the upper surface layer and the running surface side layer, Wear occurs,
There has been a problem that a gap is generated between the fabrics or the fabrics are separated from each other. This is because the endless belt is hung on several rolls and runs, and in the part where the fabric contacts the roll, the two-layer fabric is curved along the arc of the roll and the difference in circumferential length between the layers of the fabric is large. Because it will occur. As a result, the binding yarns interwoven with the layers are rubbed and internal wear occurs. Internal wear is often seen in binding yarns with a small wire diameter and low strength used to improve surface properties. The binding force of the upper surface layer and the running surface side layer only with the binding yarn having a small wire diameter was insufficient. In addition, the binding yarn is entangled with the yarn of the upper surface side layer to connect the two fabrics, and the binding force pulls the yarn to form a recess in the upper surface side surface to deteriorate the surface property of the fabric. There was also. Therefore, a multi-layer woven fabric has been developed which uses warp ground yarn binding yarns that form an upper surface on the warp direction yarns and also weave the upper surface side layer and the running surface side layer. In the upper layer, the upper surface was formed by weaving the upper surface-side weft yarn together with the upper surface-side warp yarn and forming the upper surface-side warp yarn. The running surface side layer was formed by the running surface side warp and the running surface side weft. Further, for the purpose of improving the binding force and making the openings even, a woven fabric or the like has been developed in which all of the warp yarns forming the upper surface side layer are warp ground yarn binding yarns. However, in the conventional multi-layer woven fabric that is bound by the warp ground yarn binding yarn, a set of two warp ground yarn binding yarns is arranged next to one running surface side warp yarn. Since one set of warp ground yarn binding yarns is always arranged adjacent to the same running surface side warp yarn, in the running face side layer, two warp ground yarn binding yarns are biased to the side of one running face side warp yarn. Are arranged. Similarly, in the upper surface side layer, the two warp ground yarn binding yarns forming a set are arranged in a biased manner as in the running surface side layer,
There was a problem that the uniformity of the drainage space could not be ensured and uniform dehydration could not be performed.

[0003]

SUMMARY OF THE INVENTION In view of the above problems, the present invention is a warp yarn that is woven with an upper surface side weft to form a part of the upper surface side surface and connects the upper surface side layer and the running surface side layer. Two warp binding yarns are arranged in one set, and two warp ground yarn binding yarns that form a set on the running surface side are respectively brought close to the traveling face side warp yarns on both sides, and two warp binding yarns form a set on the upper surface side. The woven fabric having a structure in which the warp binding yarns of the above-mentioned warp alternately appear on the upper surface side and they approach each other to form a structure of substantially one warp above the approximately center between the warp on the running surface side.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The industrial woven fabric of the present invention is used as an industrial woven fabric such as a papermaking wire, a conveyor belt and a filter cloth, and is particularly suitable as a papermaking wire that is strictly requested by users. Can be used for The present invention is an industrial multilayer woven fabric comprising at least an upper surface side layer and a traveling surface side layer, and connecting the upper surface side layer and the traveling surface side layer by warp binding yarn forming a part of the upper surface side layer. A part or all of the upper surface side warp was used as the warp ground yarn binding yarn. Two warp ground yarn binding yarns are arranged in a set in the running direction of the fabric, and the upper surface is formed together with the upper surface side warp yarns or the warp yarn ground yarn binding yarns alone to form two warp ground yarn binding yarns. When one of them is on the upper surface side surface, the other yarn is present on the lower side of the upper surface side layer and alternately appears on the upper surface side surface to form a structure of substantially one upper surface side warp. , Is woven with the upper surface side weft to form a part of the upper surface side surface. In the traveling surface side layer, one of the two warp ground yarn binding yarns forming a set is close to the traveling surface side warp yarn that is closer to that yarn, and the other warp yarn The yarns are separated from each other in the vicinity of the running surface side warp, and on the upper surface side, the two warp ground yarn binding yarns are close to each other in the center of the running surface side warp yarns. A structure was formed in which the design of the upper surface side warp was formed on the upper side. Since this multi-layer woven fabric uses warp ground yarn binding yarns arranged in the warp direction for connecting the two layers, the binding force is strong, and the warp yarn ground yarn binding yarns have two layers. Since it forms a part of the upper surface side layer while binding, it has excellent surface smoothness, and on the upper surface side, two warp ground yarn binding yarns are paired on the upper side of the center between the running side warps. In order to form a structure of substantially one warp, a uniform mesh space is provided on the entire surface of the woven fabric, and the drainage becomes uniform.

[0006] The greatest effect of arranging the warp ground yarn binding yarn for weaving two layers in the running direction of the fabric as in the present invention is the conventional binding which does not participate in the formation of the surface texture. Unlike the yarns, the warp ground yarn binding yarns function as a part of the surface of the woven fabric, so that local dents do not occur. In addition, since the warp yarn binding yarn is used while being stretched in the warp direction, that is, generally in the running direction of the woven fabric and always under tension, the slack of the yarn does not occur, and the woven fabric structure does not cause any slack. It tends to be strong. Two warp ground yarn binding yarns are arranged between the warp yarns in one set, and one of the two warp ground yarn binding yarns forming a set in the traveling surface side layer is the yarn. By arranging it so that it is arranged adjacent to the running surface side warp that is closer to the other side, and the other warp ground yarn binding yarn is arranged adjacent to the running surface side warp that is closer to that yarn, it becomes a set in the running surface side layer. The warp ground yarn binding yarns are arranged apart from each other, whereby a relatively large drainage space can be secured. Further, in the upper surface side layer, a design for substantially one upper surface side warp is formed above the center between the two traveling surface side warps. That is,
Since all the warp-direction yarns forming the upper surface layer are arranged at equal intervals, a uniform drainage space is arranged in the upper surface layer. Further, when the running surface side warp passes under the running surface side weft, it is preferable that one warp ground yarn binding yarn adjacent thereto passes under the same running surface side weft.
That is, of the two warp ground yarn binding yarns on the left side, the warp ground yarn binding yarn on the left side is the warp yarn which is disposed on the left side when the running face side warp passes below the running face side weft yarn. The structure is such that the ground yarn binding yarn passes under the same running surface side weft yarn, and the right warp ground yarn binding yarn of the set of two warp ground yarn binding yarns is arranged on the right side of the running yarn. Where the surface side warp passes under the running surface side weft, the warp ground yarn binding yarn passes under the same running surface side weft. With this structure, the warp ground yarn binding yarns are arranged close to the traveling surface side warp yarns on both sides, so that the two warp ground yarn binding yarns are arranged separately in the traveling face side layer. A relatively large drainage space can be formed in the traveling surface layer. There is also an effect that it is possible to reduce the wear of the warp ground yarn binding yarn, which is generally smaller in diameter than the running surface side warp.

There are a method of using both the upper surface side warp and the warp ground yarn binding yarn as a warp forming the upper surface side layer, and a method of using only the warp ground yarn binding yarn. The upper surface side warp, the warp ground yarn binding yarn, the running surface side warp, and the like that form the woven fabric are not particularly limited in structure, but the upper surface side layer may have a structure that does not easily give the woven fabric mark to the wet paper. Desirably, the running surface side layer preferably has a structure that is resistant to abrasion caused by running of the fabric. On the traveling surface side, the traveling surface side warp yarns may be arranged in the traveling surface side layer, and the warp ground yarn binding yarns which are paired therebetween may be arranged therebetween. The design of the warp ground yarn binding yarn may be the same or different. As an example of using warp ground yarn binding yarns of different design, one upper surface side weft and one upper surface side weft are alternately passed to form six knuckles on the upper surface side, and then 5 A warp ground yarn binding yarn having a design that passes under the upper surface side wefts, then under one running surface side wefts, and then under the seven upper surface side wefts, There is one formed by combining two warp ground yarn binding yarns with a structure in which the traveling direction is opposite. This reverse design is only because the adjacent running surface side warp and the warp ground yarn binding yarn are adjacent to each other and pass under the same running surface side weft. Absent. Preferably, as in this example, one running surface side weft includes both running surface side warps and warp ground yarn binding yarns, that is, adjacent running surface side warps and warp yarns A structure in which the adjacent weft yarns pass under the same running surface side weft can ensure the drainage space of the running surface side layer, the stability of the warp ground yarn binding yarn, and a countermeasure against abrasion. This design is a design in which two warp ground yarn binding yarns are combined to form a plain weave on the upper surface. When the woven surface has a plain weave structure, the number of fiber supporting points is increased, so that the fiber supporting property is improved, and the texture is fine, and thus the surface smoothness is excellent. As described above, it is preferable that the warp ground yarn binding yarns forming the upper surface side layer have a design in which a set of two does not give a mark to the paper. Also, in the case of a structure in which the warp yarn binding yarn is different,
You may arrange | position by combining them right and left for every group. This is because the diagonal mark appearing on the surface of the woven fabric can be destroyed, and it is suitable for papermaking fabrics and the like in which the surface property of the woven fabric is important. The design of the running surface side warp is not particularly limited and may be appropriately determined depending on the combination with the warp ground yarn binding yarn.

The yarn used in the present invention may be selected according to the application or the function of each yarn on the woven fabric. For example, in addition to monofilament, multifilament, spun yarn, crimping process, bulking process and the like are performed. Generally, textured yarns, bulky yarns, stretched yarns, or processed yarns, or yarns obtained by combining these yarns can be used. Further, the cross-sectional shape of the thread is not limited to a circular shape, and a short-shaped thread such as a quadrilateral shape or a star shape, an oval shape, or a hollow thread can be used. Also, the material of the thread can be freely selected, and polyester, nylon, polyphenylene sulfide, polyvinylidene fluoride, polypro, aramid, polyether ether ketone, polyethylene naphthalate, polytetrafluoroethylene, cotton,
Wool, metal, etc. can be used. Needless to say, a yarn obtained by blending or containing a copolymer or these materials with various substances depending on the purpose may be used.

As the papermaking wire, it is generally preferable to use polyester monofilaments which are rigid and have excellent dimensional stability for the upper surface side warp, the running surface side warp and the upper surface side weft. As the warp binding yarn, it is preferable to use polyester monofilament like the upper surface side warp. The upper surface side warp and the warp base yarn binding yarn may be the same or different in type, line diameter, etc., and can be selected at any time depending on the properties of the woven fabric, the weavability, 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 yarns are often arranged between the warp yarns in pairs, it is preferable to use yarns with different diameters. Is preferred. In addition, it is preferable to interlace the polyester monofilament and the nylon monofilament alternately on the running surface side weft, which requires abrasion resistance, because the abrasion resistance can be improved while ensuring the rigidity. Each wire diameter may be selected according to the application and appropriateness. Generally, it is preferable to use a relatively small diameter yarn for the upper surface side warp and the upper surface side weft which form the upper surface side layer. It is preferable to use relatively large diameter yarns for the running surface side warp and the running surface side weft forming the side layers. Also, since the warp binding yarns that interweave the upper surface layer and the running surface layer while forming the upper surface by one set are arranged in pairs, the diameter is smaller than the upper surface side warp. Although some are preferable, they may be appropriately changed according to the intended use and the desired physical properties.

Embodiments of the invention will be described based on embodiments with reference to the drawings. 1 and 2 are design diagrams showing the complete design of the embodiment of the present invention. The complete design is the smallest repeating unit of the woven design, and the complete design is connected vertically and horizontally to form the entire design of the woven design. Also, FIG.
2 is a cross-sectional view of the weft yarn 15 'in the design diagram, and FIG. 4 is a cross-sectional view of the weft yarn 1'in the design diagram of FIG. In the design drawing, warp and warp ground binding yarn are Arabic numerals, for example, 1, 2, 3, ...
Indicated by. Odd number of warp threads, for example 1, 3,
5 ..., upper surface side warp and running surface side warp are arranged vertically. The even numbered numbers 2, 4, 6 ... are a set of warp ground yarn binding yarns, and 2a and 2b, 3a and 3b ... 24a.
And 24b are paired and arranged in pairs between the warps. The weft is an Arabic numeral with a dash, eg 1
It is shown by ', 2', 3 '. The upper surface side weft and the running surface side weft are respectively arranged above and below. A cross indicates that the upper surface side warp or the warp binding yarn binds above the upper surface side weft to form a knuckle, and a ○ indicates that the running surface side warp is located below the running surface side weft. Indicates that the warp ground yarn binding yarn is located below the running surface side weft yarn. In the present embodiment, the upper surface side weft and the running surface side weft, and the upper surface side warp and the running surface side warp are arranged on top of each other for convenience sake in the design drawing, but they may be arranged to be offset in an actual fabric. . Also, the warp ground yarn binding yarns a and b that are paired are arranged in parallel on the design diagram, but in reality, there are portions that are arranged one above the other.

Example 1 In the design diagram of FIG. 1, this example is a two-layer woven fabric composed of warp ground yarn binding yarn, upper surface side warp, upper surface side weft, running surface side warp and running surface side weft. The upper surface side warp and the warp ground yarn binding yarn are arranged on the warp forming the upper surface side layer, and are arranged between the warp threads 2
The upper layer and the lower layer are woven by one set of warp ground yarn binding yarns. In the embodiment of FIG. 1, a set of two warp ground yarn binding yarns is arranged between the warps, and when one of these is exposed on the upper surface side, the other is below the upper surface surface,
In this way, a design is obtained in which the design of substantially one warp is formed on the upper surface side weft and the non-woven upper surface side surface. A set of two warp ground yarn binding yarns passes through the upper side and the lower side of one upper surface side weft to form a plain weave design for one substantial warp. On the running surface side, of the two warp ground yarn binding yarns forming the set, the warp ground yarn binding yarn (yarn with a) arranged on the left side in the design drawing is placed on the left side. And the other warp ground yarn binding yarn (yarn with b) is arranged in close proximity to the warp yarn arranged on the right side thereof. This is because the warp ground yarn binding yarn is woven together with the running face side warp by one running face side weft, and the warp ground yarn binding yarn having a smaller diameter than the running face side warp is the running face side warp. It will move to the side and will be placed closer. In other words, since the warp ground yarn binding yarns forming a set are arranged apart from each other in the running surface side layer, a relatively large drainage space is formed between them, and the woven fabric is excellent in drainage. Further, in the upper surface side layer, the two warp ground yarn binding yarns forming a set are close to each other and are located above the substantially center between the traveling surface side warp yarns, and are woven with the upper surface side weft yarns to substantially form one warp yarn. Form a plain weave structure for the minutes.
One of the pair of warp ground yarn binding yarns is below the upper surface side layer, and the other one is below the running surface side weft yarn and weaves the two layers together. The two wires are not arranged adjacent to the upper surface side layer at the same time but alternately appear on the upper surface side surface. Among the warp ground yarn binding yarns thus formed, when the yarn arranged on the left side of the design drawing forms the upper surface side layer, when the other warp ground yarn binding yarn in the set is Since it does not appear in the upper layer, the force to move it to the right side on the design drawing works. On the other hand, since the warp ground yarn binding yarn arranged on the right side does not show the other warp ground yarn binding yarn in the pair in the upper surface side layer, a force to move to the left side on the design drawing works.
As a result, a force acts on the two warp ground yarn binding yarns in a direction in which they face each other, and a structure such as one upper surface side warp is formed on the upper surface side surface at approximately the center between the warp threads. Further, since the upper surface side warp also forms a plain weave design, the upper surface side surface forms a plain weave design with a pair of warp ground yarn binding yarn, upper surface side warp and upper surface side weft. In addition, since the warp ground yarn binding yarn has the above structure, a uniform drainage space is formed between the warp yarns forming the upper surface. FIG. 1 is one of the embodiments of the present invention, in which two warp ground yarn binding yarns having different designs are provided between the warp yarns.
Two warp ground yarn binding yarns forming a set are arranged close to adjacent running surface side warp yarns in the running surface side layer, and in the upper surface side layer, almost between the two running surface side warp yarns. When one warp ground yarn binding yarn appears on the upper surface in the upper part of the center, the other is on the lower side of the upper surface and forms a design of substantially one warp. The warp ground yarn binding yarns alternately pass through one upper surface side weft and one upper surface side weft to form six knuckles on the upper surface side, and then five upper surface side wefts. The warp ground yarn binding yarn having a design of passing through the lower side, then under the one traveling surface side weft yarn, and then under the seven upper surface side weft yarns, and this warp yarn base yarn binding The thread is formed by combining two yarns that are oriented in opposite directions to each other. More specifically, taking the warp ground yarn binding yarn 2 as an example, the warp ground yarn binding yarn 2a passes under one traveling surface side weft yarn 1 ', and then seven upper surface side weft yarns 2', 3 ', 4', 5 ',
6 ', 7', 8'and running surface side wefts 2 ', 3', 4 ', 5
A knuckle is formed on the upper surface side by passing between the upper surface side weft 9'and the upper surface side weft 9 ', and then the upper surface side weft 10' and the running surface side. A knuckle is formed on the upper surface side by passing between the wefts 10 'and one upper surface side weft 11', and passing between one upper surface side weft 12 'and the running surface side weft 12', One upper surface side weft 13 '
A knuckle is formed on the upper surface side through the upper side of the ridge and passes between one upper surface side weft 14 ′ and the running surface side weft 14 ′.
A knuckle is formed on the upper surface side through the upper side of the upper surface side weft 15 ′ and passes between one upper surface side weft 16 ′ and the running surface side weft 16 ′. A knuckle is formed on the upper surface side through the upper side, passes between one upper surface side weft 18 'and the running surface side weft 18', and passes over one upper surface side weft 19 'to the upper surface side surface. Form a knuckle, then 5 upper surface side wefts 20 ', 21', 22 ',
23 ', 24' and running surface side wefts 20 ', 21', 22
It is a tissue that passes between ', 23', and 24 '. The warp ground yarn binding yarn 2b paired therewith passes over one upper surface side weft 1'to form a knuckle on the upper surface side, and one upper surface side weft 2'and one running surface side weft 2 '. Knuckle is formed on the upper surface side by passing between the upper surface side weft 3'and the upper surface side weft 4'and the running surface side weft 4 '. A knuckle is formed on the upper surface side through the upper side of the upper surface side weft 5'and passes between one upper surface side weft 6'and the running surface side weft 6'and the upper side of one upper surface weft 7'is A knuckle is formed on the upper surface side through, and 7 upper surface side wefts 8 ', 9', 10 ', 11', 12 ', 13', 14 '
And running surface side wefts 8 ', 9', 10 ', 11', 12 ',
It passes between 13 'and 14', then passes under one running surface side weft 15 ', and five upper surface side wefts 16' and 17 '
', 18', 19 ', 20' and running surface side weft 16 ', 1
7 ', 18', 19 ', 20' pass through one upper surface side weft 21 'to form a knuckle on the upper surface side, and then one upper surface weft 22' and the running surface. Side weft 2
A structure in which a knuckle is formed on the upper surface side by passing between the upper surface side wefts 23 'and between the upper surface side wefts 24' and the running surface side wefts 24 '. Is. In this pair of warp ground yarn binding yarns, 2a and 2b have opposite designs when viewed in the traveling direction, that is, in the vertical direction of the design drawing. These two warp ground yarn binding yarns 2a and 2b are arranged in parallel between the two warp yarns 1 and 3 on the design diagram, but in reality, in the running surface side layer, the warp ground yarn binding yarns are arranged. Since the binding yarn 2a is woven together with the running surface side warp 1 by the running surface side weft 1 ', the warp ground yarn binding yarn 2a having a diameter smaller than that of the running surface side warp 1 moves to the running surface warp 1 side. Are arranged close to the running surface side warp yarns 1, and the warp ground yarn binding yarns 2
Since b is woven together with the running surface side warp 3 by the running surface side weft 1, the warp ground yarn binding yarn 2b having a diameter smaller than that of the running surface side warp 3 moves to the running surface warp 3 side and moves. It is arranged close to the side warp 3. This is because when the running surface side warp passes under the running surface side weft, the warp ground yarn binding yarn that is close to it runs under the same running surface side weft. Since the pair of warp ground yarn binding yarns are close to the traveling surface side warp yarns on both sides, a relatively large drainage space can be formed in the traveling surface side layer, and freeness can be improved. . In addition, by arranging the running surface side knuckle of the warp ground yarn binding yarn adjacent to the running surface side knuckle of the running surface side warp, it is possible to make a stable fabric without movement of the warp ground yarn binding yarn. Further, it also has the effect of reducing the wear of the warp ground yarn binding yarn having a smaller wire diameter than the running surface side warp.
In the upper surface side layer, the warp ground yarn binding yarns alternately appear on the upper surface side and are interwoven with the upper surface side weft yarns to function as one warp yarn. In the warp ground yarn binding yarn 2, The warp yarn binding yarn 2a is the upper surface side wefts 9 ', 10', 11 ', 1

Functions like a single warp above the center of the running surface side warp 1 and the running surface side warp 3, and is woven with the upper surface side weft to form a plain weave design. This is because one of the warp ground yarn binding yarns forming a pair forms the upper surface side layer while the other warp ground yarn binding yarn appears in the upper surface side layer. Rather, the two warp ground yarn binding yarns alternately form the upper surface side surface, so that a force acts in a direction in which they face each other, and they function like one upper surface side warp at approximately the center between the warp yarns. The warp yarns arranged on both sides of the warp ground yarn binding yarn are also interwoven with the warp ground yarn binding yarn, the upper surface side warp yarn and the upper surface side weft yarn on the upper surface side to form a plain weave design on the entire upper surface side surface. . Since the plain weave structure can form a dense surface, it has excellent smoothness and can secure a uniform drainage space. In the weft direction, the upper surface side wefts and the running surface side wefts are arranged in the same number in the upper and lower sides, but other arrangement ratios are also possible, and the running surface side layer is a weft wear type structure capable of withstanding the wear caused by running of the fabric. There is. In the running surface side weft 1 ', after passing over one running surface side warp 1 and the warp ground yarn binding yarn 2a, five continuous running surface side warps 3, 5, 7, 9,

A knuckle is formed on the upper surface side through the upper side of the ridge and passes between one upper surface side weft 14 ′ and the running surface side weft 14 ′.
A knuckle is formed on the upper surface side through the upper side of the upper surface side weft 15 ′ and passes between one upper surface side weft 16 ′ and the running surface side weft 16 ′. A knuckle is formed on the upper surface side through the upper side, and three upper surface side wefts 18 ', 19', 20 'and running surface side wefts 18', 19

The other warp ground yarn binding yarn 2b paired therewith passes through the upper side of one upper surface side weft 1'to form a knuckle on the upper side surface, and one upper surface side weft 2'and a running surface side weft. A knuckle is formed on the upper surface side by passing between the upper surface side weft 3 ′ and the upper surface side weft 3 ′, and passing between the upper surface side weft 4 ′ and the running surface side weft 4 ′. A knuckle is formed on the upper surface side through the upper side of the upper surface side weft 5 ', and passes through between the upper surface side weft 6'and the running surface side weft 6'.

“A” is arranged close to the running surface side warp 1. The warp ground yarn binding yarn 2b is arranged close to the running surface side warp yarn 3. This is where the running surface side warp passes under the running surface side weft,
This is because the warp ground yarn binding yarn that is close to it passes under the same running surface side weft yarn. Since the pair of warp ground yarn binding yarns are close to the traveling surface side warp yarns on both sides, a relatively large drainage space can be formed in the traveling surface side layer and the freeness can be improved. In addition, by arranging the running surface side knuckle of the warp ground yarn binding yarn adjacent to the running surface side knuckle of the running surface side warp, it is possible to make a stable fabric without movement of the warp ground yarn binding yarn. Further, it also has the effect of reducing the wear of the warp ground yarn binding yarn having a smaller wire diameter than the running surface side warp.

The two warp ground yarn binding yarns 2 appearing alternately function as one warp above the center of the running surface side warp 1 and the running surface side warp 3 and function as upper surface side wefts. They are woven together to form a plain weave structure. The warp yarns arranged on both sides of the warp ground yarn binding yarn are also interwoven with the warp ground yarn binding yarn, the upper surface side warp yarn and the upper surface side weft yarn on the upper surface side to form a plain weave design on the entire upper surface side surface. . Since the plain weave structure can form a dense surface, it has excellent smoothness and can secure a uniform drainage space. In the weft direction, the upper surface side wefts and the running surface side wefts are arranged in the same number vertically,
Other arrangement ratios may be used, and the running surface side layer has a weft wear type structure capable of withstanding wear caused by running of the fabric. In the running surface side weft 1 ′, after passing over one running surface side warp 1 and the warp ground yarn binding yarn 2 a, it passes under the four running surface side warps 3, 5, 7, 9, Next, the running surface side wefts passing through the upper side of the one running surface side warp 11 and the warp ground yarn binding yarn 12a and below the four running surface side warp threads 13, 15, 17, 19 are the running surface side warp threads.

Also, in order to explain the positional relationship of the yarns in each warp direction in an easy-to-understand manner, I, II, and III lines were appropriately shown along the warp yarns. I is a straight line passing through the center of the warp yarn 1, II is a straight line passing through substantially the center of the warp yarn 1 and the warp yarn 3, and III is a straight line passing through the center of the warp yarn 3. As can be seen from FIGS. 3 and 4, the warp ground yarn binding yarns are arranged in pairs between the warp yarns, and one warp ground yarn binding yarn forms the upper surface of the lower side. The other warp ground yarn binding yarn is woven with the running surface side weft yarn. Further, the warp ground yarn binding yarns arranged between the warp yarns are woven together by the running face side weft yarns with the traveling face side warp yarns which are adjacently arranged, so that the two warp ground yarn binding yarns forming the set are Of these, the left warp ground yarn binding yarn on the design diagram of FIG. 2 is disposed close to the left running surface side warp 1, and the right warp ground yarn binding yarn of the design drawing of FIG. 3 is the right running surface side.
