Description

  The woven fabric of the present invention is suitable as a woven fabric for marking non-woven fabrics and papers, and relates to an industrial single-layer woven fabric that forms an uneven surface that is excellent in fiber support, bulkiness, etc. and can be used for high-speed machines.

Conventionally, fabrics woven with warps and wefts have been widely used as industrial fabrics that form uneven surfaces, such as wires for making nonwoven fabrics, papermaking wires, conveyor belts, and many other fields. Yes. It is used to impart marks and textures to paper, nonwoven fabric, etc. using unevenness, or to prevent slipping of conveyed items.
In particular, as a woven fabric for marking non-woven fabrics and paper, there are strict requirements such as fiber supportability, sheet peelability, and high-speed machine compatibility in addition to the height of the unevenness. In recent years, the demand has become more severe with the increase in the speed of nonwoven fabric manufacturing machines and papermaking machines.
There are various methods for marking fabrics. As disclosed in Japanese Patent Laid-Open No. 2005-9013, there is a method in which warp and weft floats (long crimps) are formed on the surface of a woven fabric so as to have a height difference in each region. Further, as disclosed in Japanese Patent Application Laid-Open No. 2004-27407, there is a method in which a thick line warp is arranged at some interval so that a mark is given due to the difference in the height of the knuckle top of the fine wire diameter warp and the thick wire diameter warp. is there. However, these are effective for imparting a geometric pattern or a spot-like pattern different from others, such as letters and streaks, but are not suitable for imparting bulk to a nonwoven fabric or the like due to the configuration of the entire fabric.
In addition, as a problem that is currently present, in the woven fabric for marking, there is a scattering of sheet raw materials due to an increase in machine speed. In wet papermaking, etc., fiber can be supplied together with a large amount of water, so a certain speed increase can be realized.However, in the case of dry papermaking, a very light fiber material is supplied on the fabric. May be scattered. This is remarkable when the fiber material is a woven fabric having a relatively flat surface. In order to solve this problem, scattering can be solved by using a woven fabric with a structure with severe unevenness, for example, but the fiber may sink under the component yarn and the sheet peelability may deteriorate. It was. As described above, the scattering of the fibers, the sheet peelability, and the unevenness imparting properties are contradictory problems.

About.
The first, second, and third knuckles that form the surface of the fabric of the present invention are convex portions that are formed along the shape of warps passing over the wefts and auxiliary wefts. The knuckle is a knuckle formed by sequentially passing over one adjacent weft yarn, one auxiliary weft yarn, or formed by sequentially passing over one adjacent weft yarn and two auxiliary weft yarns. It is a knuckle. The second knuckle refers to one auxiliary weft arranged adjacently, one knuckle formed in succession on one weft, or two auxiliary wefts arranged adjacent to each other, and one weft passed in order. The knuckle is formed. The third knuckle is a knuckle formed by sequentially passing over one auxiliary weft, one weft, and one auxiliary weft arranged adjacent to each other.

  The industrial fabric of the present invention has a structure in which two or three kinds of warp knuckles having different shapes based on a plain weave on a weft are randomly arranged on the surface on the upper surface side. It is excellent in high-speed machine compatibility and suitable for manufacturing bulky nonwoven fabrics.

The woven fabric of the present invention can be suitably used especially in the field of production of nonwoven fabrics such as spunbond, meltblown, airlaid, spunlace, wet papermaking, dry papermaking, etc. By applying a concavo-convex pattern of the woven fabric in the drying process by, for example, a bulky nonwoven fabric or a paper having a concavo-convex pattern can be produced.
The fabric of the present invention is an industrial single-layer fabric composed of warps, wefts, and auxiliary wefts having a thinner wire diameter than the wefts. Basically, wefts are preferably thick and rigid yarns, and a plurality of types of warp knuckles having substantially the same length but different shapes are randomly formed on the relatively straight wefts. Thus, in the woven fabric of the present invention, the top part of the warp knuckle is convex, the intersecting part of the warp yarns formed between adjacent wefts, and the auxiliary weft part on the intersecting part becomes the concave part, and the unevenness is caused by the height difference between them. It is formed. Moreover, since it is comprised by several warp knuckles from which a shape differs also in a convex part, it becomes a more complicated uneven | corrugated shape. The present invention forms a plurality of types of convex portions by the difference in height and the shape of the warp knuckle as described above, and does not form unevenness by the length of the warp and weft float. In this case, when the auxiliary weft is excluded, the warp and weft form a plain weave structure.

In the present invention, the warp knuckle refers to a convex portion formed along the shape of the weft thread through the top or the bottom of one weft thread, and one or a plurality of adjacent one weft threads. The convex part formed along the shape of the auxiliary weft of the book through or under is shown. Therefore, it is preferable that the warp yarn is of a wire diameter and a material that can easily bend and form a knuckle. For the height of the unevenness, the wire diameter and wire of each thread are very much involved.For example, if weft material is easy to bend, the weft will bend at the intersection of the warp and weft, and the height of the warp knuckle Becomes lower. Further, even if a rigid yarn is used as the weft, if the weft has a thin wire diameter, the whole becomes relatively flat. In addition, if the warp is made of a material that is difficult to bend, the fabric will have poor stability because the fabric does not intertwine in the vertical and horizontal directions.
The auxiliary weft is a configuration necessary for forming a plurality of types of warp knuckles having different shapes. For example, the knuckle formed through the upper side in the order of the weft and the auxiliary weft is different in shape and arrangement from the knuckle formed through the upper side in the order of the weft and the auxiliary weft. If the difference in the wire diameter between the auxiliary weft and the weft is small, the difference in the formed knuckle shape is small, so that a single type of convex portion is formed. This may be preferable, and it is necessary to examine the wire diameter balance and material of each yarn.

The arrangement ratio of the weft and the auxiliary weft may be 1: 1 in which one auxiliary weft is arranged with respect to one weft, the other 1: 2, or one after the two wefts. An arrangement of 2: 1 or the like with auxiliary wefts arranged may be used. In addition, one auxiliary weft after the one weft, then one weft, then two auxiliary wefts, or one weft. Next, one auxiliary weft, then two wefts, and then one auxiliary weft may be arranged.
As described above, the arrangement ratio and arrangement of the weft and the auxiliary weft are not particularly limited. However, when a structure in which three or more wefts are continuously arranged is formed, different structures such as a first knuckle and a second knuckle are formed. Since it becomes difficult to do, it is not preferable. For this reason, it is preferable that at most two wefts are arranged continuously. Similarly, if three or more auxiliary wefts are arranged continuously, the knuckle shape variation is increased, but the warp and weft yarns are not entangled strongly and the knuckle stability is poor, which is not preferable. Therefore, it is preferable to have a structure in which at most two auxiliary wefts are arranged continuously.

The warp knuckle that forms the upper surface side surface is constituted by any one of the following first, second, and third types or three types of knuckles, and the knuckle that forms the upper surface side surface has the same number of wefts And over the auxiliary weft. The positions of the respective knuckles are arranged at positions where warps and wefts form a plain weave structure, except for auxiliary wefts.
The first knuckle is formed by passing through a total of two or three of one weft and one or two auxiliary wefts adjacent to the warp, and the second knuckle is one adjacent Or the two knitting wefts and one weft that is formed by passing through a total of two or three in order, the third knuckle is one auxiliary weft, one weft and one A total of three auxiliary weft yarns are formed in order.
In the present invention, “the upper surface is composed of knuckles formed on the same number of wefts and auxiliary wefts” means that the upper surface of the woven fabric is one weft and 1 It is formed only of knuckles that pass over a total of two auxiliary wefts. Therefore, a knuckle that passes over a total of three wefts and two auxiliary wefts passing through one weft and two auxiliary wefts adjacent to each other in the fabric structure, and one weft and three auxiliary wefts arranged adjacent to each other. There are no knuckles or the like that pass above, a total of four.
For example, when the upper surface side surface is constituted by a total of two warp knuckles that pass over one weft and one auxiliary weft adjacent to the warp, the first knuckle is arranged so that the warps are adjacent to each other. The two knuckles are formed by passing through a total of two weft yarns and one auxiliary weft yarn in order, and the second knuckle extends over a total of two auxiliary weft yarns and one weft yarn arranged adjacent to each other. They are formed in order. The first knuckle and the second knuckle differ only in the arrangement position of the auxiliary weft arranged adjacent to the weft on the fabric structure, but the shape of the knuckle formed on the straight weft is still different, Two types of warp knuckles having different shapes are formed on the weft on the upper surface side, and two types of protrusions having different shapes in the width direction are formed. In addition, the knuckle is arranged in the front including the weft and the rear including the weft, so that the knuckles are not arranged in a straight line, and the shape and arrangement become random uneven surfaces.
As another example, when the upper surface side is composed of a total of three warp knuckles that pass over one weft and two auxiliary wefts adjacent to the warp, the first knuckle It is formed by passing over a total of three adjacent weft yarns and two auxiliary weft yarns, and the second knuckle is a total of three auxiliary weft yarns and one weft yarn arranged adjacent to each other. The third knuckle is formed by sequentially passing over a total of three auxiliary wefts, one weft and one auxiliary weft arranged adjacent to each other. Even if the upper surface is formed of two types of knuckles, the first knuckle and the second knuckle, or the first knuckle is formed of two types of knuckles, the first knuckle and the third knuckle. And 3 types of knuckles, 2nd and 3rd knuckles But it may be those which are.
Also, there is no limitation as to which warp forms which knuckle. For example, a structure in which one warp forms only the first knuckle and the other one warp forms only the second knuckle. Alternatively, a structure in which one warp forms a first knuckle and a second knuckle and another warp forms only a third knuckle may be used. Any material may be used as long as the upper surface is composed of knuckles formed on the same number of wefts and auxiliary wefts.

There is no particular limitation on the structure of the auxiliary weft, but it is not preferable to use a structure that passes over many continuous warps. Although there is an effect of improving the fiber supportability by arranging the auxiliary wefts between the wefts, the present invention forms warp knuckles having different shapes on the surface on the upper surface side, so that if the auxiliary wefts float too long When the structure is limited and used as a woven fabric for manufacturing a nonwoven fabric, it is necessary to consider them because fibers as a nonwoven fabric material may sink under a long auxiliary weft and reduce sheet peelability. Preferably, the structure passes above and below one warp, or the structure passes above two continuous warps and below two warps. Although the structure of the auxiliary weft may be one type or more, it is preferable that the entire woven fabric has one or two types of structures. It is not preferable to arrange too many types of structures because of problems of weaving properties and tension balance of the fabric.
The weft structure is a structure in which an upper side and a lower side of one warp are alternately passed to form a plain weave structure on the upper surface side and the lower surface side. In the warp structure, the structure from which the auxiliary weft is removed is a structure that forms a plain weave structure. The woven fabric of the present invention forms a complex uneven surface due to the top part of the warp knuckle and the intersecting part of the warps formed between the adjacent wefts, the height difference of the recesses due to the auxiliary wefts, and the difference in the shape of the warp knuckle. Basically, weaving is based on plain weave because it does not form irregularities depending on the length of warp and weft lifting.
In the case of the plain weave structure referred to in the weft of the present invention, since the weft is woven by a rigid and difficult to bend and a warp which is easy to form a knuckle, the weft does not protrude on the upper surface side and the lower surface side. Since the weft yarns pass through one warp and the lower one in sequence, it can be said that the structure is a plain weave.

  Although the lower surface is not particularly limited, since the warp is a structure that forms a plain weave when the auxiliary weft is removed, a warp knuckle that passes under one weft on the lower surface or one continuous thread And a warp knuckle passing under one to four auxiliary wefts. The configuration of the lower surface side knuckle formed by the warp on the lower surface side is always one weft, but the number of auxiliary wefts combined therewith is 0, 1, 2, 3 or 4 at maximum. Good. For example, a lower side knuckle that passes through one weft, an adjacent one weft, a lower side knuckle that passes through a total of two lower sides of one auxiliary weft, an adjacent auxiliary weft, one Lower side knuckles that pass sequentially through a total of three lower sides of one weft, a lower side knuckle that passes through a total of three lower sides of two adjacent auxiliary wefts and one weft, It may be a lower side knuckle that sequentially passes through a total of five lower sides of two adjacent auxiliary wefts, one weft, and two auxiliary wefts. The lower surface is not limited which warp forms which knuckle. For example, a lower knuckle in which one warp passes below one weft and two auxiliary wefts adjacent to the lower surface. And may be a structure forming two knuckles of a lower surface side knuckle passing under one weft, and the warps constituting the woven fabric may be the same structure or different structures. . The lower surface may be any surface as long as the warp is composed of one weft, or one adjacent weft and one to four lower knuckles. What is necessary is just to select suitably from these relationships.

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. 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. Further, in particular, as a woven fabric for manufacturing a nonwoven fabric, a conductive yarn may be used as a part of the woven yarn in order to prevent generation of static electricity. I do not care.
Polyphenylene sulfide and the like are preferable in a high temperature atmosphere, and polyester and polyamide are generally used as industrial fabrics. In particular, the weft constituting the woven fabric of the present invention is preferably a rigid and difficult-to-bend yarn. Therefore, monofilaments, converging yarns in which monofilaments are bundled, twisted yarns and the like are suitable, and those having a relatively large wire diameter are preferred. In the warp, those having a diameter and material that are easy to bend along the shape of the weft and the auxiliary weft to form a knuckle are preferable, and monofilaments, converging yarns in which monofilaments are bundled, twisted yarns, and the like are suitable. Those having a smaller wire diameter are preferable. As auxiliary wefts, monofilaments, multifilaments, twisted yarns, decorative yarns, hollow yarns, etc. are suitable, and they are also used for tension adjustment of warps with large bends in the weaving stage of fabrics. Rather, a flexible yarn is preferred.
In addition, flat yarns are sometimes used for non-woven fabric production purposes for purposes such as resistance to dirt, ease of cleaning, and making smooth joints when joining endlessly. In both the weft and the auxiliary weft, not only a circular cross section but also a short thread such as a quadrangle and a star, and a flat, elliptical and hollow thread can be used. Of course, they may be used in combination. For example, the warp yarn may be a flat cross-sectional yarn, the weft yarn and the auxiliary weft yarn may be a circular cross-sectional yarn, and some of the flat warp yarns may be circular warps. For example, in a high-speed machine for manufacturing nonwoven fabrics, if the surface of the fabric is too smooth, the fiber sheet formed on the fabric may be scattered. Therefore, for the purpose of providing a structure in which fibers are pierced into the woven fabric to some extent, we may weave as a circular warp in which a part of two flat warps are aligned. Such a woven fabric has an effect that the fibers are appropriately inserted and scattering of the sheet is suppressed. However, if too many circular warp yarns are arranged, the fibers may be stuck too much and the sheet peelability may be deteriorated.
Also, within this specification the upper side surface so as to facilitate explanation, has been described as the lower surface side surface, the raw material contact surface either for a single layer fabrics, may be used as the machine contact surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings.
FIGS. 1-31 is an Example of this invention, Comprising: It is either a design drawing, sectional drawing along warp, or sectional drawing along weft. 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 and wefts are indicated by Arabic numerals, for example, 1, 2, and 3, and auxiliary wefts are indicated by Arabic numerals with dashes, for example, 1 ′, 2 ′, and 3 ′.
In addition, the x mark indicates that the warp is located above the weft, and the portion where the warp knuckle is formed by passing the warp over the weft and the auxiliary weft is shaded.
In the design drawing and the cross-sectional view, the weft and the auxiliary weft are arranged at equal intervals, but they may be arranged so as to be shifted due to the structure.

Example 1
FIG. 1 is a design diagram of a fabric of Example 1 of the present invention. FIG. 2 is a sectional view taken along warps 1, 2, 3, and 4 of the design diagram of FIG. FIG. 3 is a sectional view taken along the weft 1 and the auxiliary weft 2 'of the design diagram of FIG. FIG. 4 is a cross-sectional view of the warp where the adjacent warps 1 and 2, 2 and 3, 3 and 4, 4 and 1 intersect. One weft and one auxiliary weft are alternately arranged at a ratio of 1: 1. The symbols A to D on the design drawing represent the positions of the recesses A to D.
The weft yarn is a rigid yarn that has a relatively large wire diameter and is difficult to bend. On the other hand, the warp yarn and the auxiliary weft yarn are bent to easily form a knuckle. Therefore, as can be seen from the cross-sectional view along the weft 1 in FIG. 3, a relatively straight knuckle is formed on both the upper surface side and the lower surface side of the weft.
As shown in the design diagram of FIG. 1, the upper surface side surface is formed by passing the upper side of a total of two yarns, one weft and one auxiliary weft adjacent to each other, in order. The knuckle is composed of two knuckles of a second knuckle formed in order through the upper side of a total of two yarns, one auxiliary weft yarn and one weft yarn arranged adjacent to each other. Each of the first knuckle and the second knuckle is a knuckle formed through two upper sides of one weft and one auxiliary weft. Specifically, in the warp 1, the knuckle passing above the adjacent weft 1 and the auxiliary weft 2 ', and the knuckle passing above the adjacent weft 5 and the auxiliary weft 6' is the first knuckle, and the warp 3 is adjacent. The knuckle passing over the auxiliary weft 4 'and the upper side of the weft 5 and the knuckle passing over the adjacent auxiliary weft 8' and the upper side of the weft 1 are the second knuckle. These are knuckles having different shapes from the cross-sectional views of the warp 1 and the warp 3 shown in FIG.
As can be seen from the weft 1 in FIG. 3, the weft is a plain weave structure that alternately passes above and below one warp. Similarly, if the auxiliary weft is removed from the cross section of the warp, the warp is also above one weft. It is a plain weave structure that passes alternately under. The structures of the auxiliary wefts are all the same structure, and are the structures passing over the two warps and under the two warps. Since it is an appropriate length, the sheet peelability is not hindered while improving the fiber support.
The lower surface side surface is formed by a lower surface side knuckle passing under one adjacent lower surface side weft and one auxiliary weft.
Moreover, the unevenness | corrugation of this textile fabric is demonstrated with reference to FIG. 4 which showed sectional drawing of the adjacent warp. The warps are arranged in the order of warps 1, 2, 3, 4 as shown in the design drawing. Between the warps 1 and 2, the warp 1 passes over the weft 1 and the auxiliary weft 2 ′ to form a first knuckle on the upper surface, then passes under the weft 3 and the auxiliary weft 4 ′, and then the weft 5 The first knuckle is formed on the auxiliary weft 6 ', and then the structure passes under the weft 7 and the auxiliary weft 8'. The warp 2 passes under the weft 1 and the auxiliary weft 2 ', then passes over the weft 3 and the auxiliary weft 4' to form a first knuckle on the upper surface, and then the weft 5 and the auxiliary weft 6 ' The structure passes through the bottom and then forms the first knuckle on the weft 7 and the auxiliary weft 8 '. As a result, the warp 1 and the warp 2 are in this order on the weft 1 and the auxiliary weft 2 ', on the weft 3 and the auxiliary weft 4', on the weft 5 and the auxiliary weft 6 ', and on the weft 7 and the auxiliary weft 8'. First knuckles are formed, and these knuckles become convex portions. A warp intersects between the warp 1 and the warp 2 to form a recess A. This is where warp 1 falls from above auxiliary weft 2 'to below weft 3, and where warp 2 falls from above weft 3 to below auxiliary weft 2'. A difference in height from the top will occur. Similarly, recesses A are also formed between the weft 4 and the auxiliary weft 5 ', between the weft 6 and the auxiliary weft 7', and between the weft 8 and the auxiliary weft 1 '.
Between the warps 2 and 3, the warp 2 passes under the weft 1 and the auxiliary weft 2 ', and then passes over the weft 3 and the auxiliary weft 4' to form a first knuckle on the upper surface. Subsequently, the structure passes through the weft 5 and the auxiliary weft 6 'and then forms the first knuckle on the weft 7 and the auxiliary weft 8'. In the warp 3, a second knuckle is formed on the upper surface through the auxiliary weft 8 ′ and the weft 1, and then passes under the auxiliary weft 2 ′ and the weft 3, and then on the auxiliary weft 4 ′ and the weft 5. The second knuckle is formed in the second knuckle, and then the structure passes under the auxiliary weft 6 'and the weft 7. As a result, the warp 2 and the warp 3 are on the auxiliary weft 8 'and the weft 1, on the weft 3 and the auxiliary weft 4', on the auxiliary weft 4 'and the weft 5, and on the weft 7 and the auxiliary weft 8'. A 2nd knuckle and a 1st knuckle are formed in order, and the top part of these knuckles becomes a convex part from which a shape differs. A warp intersects between the warp 2 and the warp 3 to form a recess B and a recess C.
In the recess B, the auxiliary weft 2 'is present at the intersection of the warp 3 from the weft 1 below the auxiliary weft 2' and the warp 2 from the weft 3 below the auxiliary weft 2 '. It is the most depressed place. Similarly, a recess B in which the auxiliary weft 6 ′ is present is formed between the weft 5 and the weft 7. In this way, a recess in which the auxiliary weft is present is formed between the top of the first knuckle and the top of the second knuckle, resulting in a difference in height.
The concave portion C is an intersection of a portion where the warp 2 passes over the auxiliary weft 4 'and a portion where the warp 3 passes over the auxiliary weft 4'. Since the concave portion C is not an intersection where the warp goes downward, the concave portion is smaller than the other concave portions A and B, but a concave portion is formed as compared with the top of the knuckle. Similarly, a recess C is formed on the auxiliary weft 8 '.
Between the warps 3 and 4, the warp 3 passes over the auxiliary weft 8 'and the weft 1 to form a second knuckle on the upper surface, and then passes under the auxiliary weft 2' and the weft 3, Next, the second knuckle is formed on the auxiliary weft 4 ′ and the weft 5, and then the structure passes under the auxiliary weft 6 ′ and the weft 7. The warp 4 passes under the auxiliary weft 8 'and the weft 1 and then passes over the auxiliary weft 2' and the weft 3 to form a second knuckle on the surface on the upper surface side, and then the auxiliary weft 4 'and the weft 5 The structure passes through the bottom and then forms the second knuckle on the auxiliary weft 6 ′ and the weft 7. As a result, in the warp 3 and the warp 4, the auxiliary weft 8 'and the weft 1, the auxiliary weft 2' and the weft 3, the auxiliary weft 4 'and the weft 5, the auxiliary weft 6' and the weft 7 in that order. A 2nd knuckle is formed and the top part of these knuckles becomes a convex part. The warp intersects between the warp 3 and the warp 4 to form a recess D. This is where the warp 3 falls from the top of the weft 1 to below the auxiliary weft 2 'and the warp 4 falls from the top of the auxiliary weft 2' to below the weft 1, where the second knuckle A difference in height from the top will occur. Similarly, recesses D are also formed between the weft 3 and the auxiliary weft 4 ', between the weft 5 and the auxiliary weft 6', and between the weft 7 and the auxiliary weft 8 '.
Between the warps 4 and 1, the warp 4 passes under the auxiliary weft 8 'and the weft 1, and then passes over the auxiliary weft 2' and the weft 3 to form a second knuckle on the upper surface. Subsequently, the structure passes through the auxiliary weft 4 ′ and the weft 5 and then forms a second knuckle on the auxiliary weft 6 ′ and the weft 7. In the warp 1, the first knuckle is formed on the surface of the upper surface through the weft 1 and the auxiliary weft 2 ', then passes under the weft 3 and the auxiliary weft 4', and then on the weft 5 and the auxiliary weft 6 '. The first knuckle is formed, and then the structure passes under the weft 7 and the auxiliary weft 8 '. As a result, warp 4 and warp 1 are on weft 1 and auxiliary weft 2 ', on auxiliary weft 2' and weft 3, on weft 5 and auxiliary weft 6 ', on auxiliary weft 6' and weft 7. A 1st knuckle and a 2nd knuckle are formed in order, and the top part of these knuckles becomes a convex part from which a shape differs. A warp intersects between the warp 4 and the warp 1 to form a recess C and a recess B.
The concave portion C is an intersection of a portion where the warp 4 passes over the auxiliary weft 2 'and a portion where the warp 1 passes over the auxiliary weft 2'. Since the concave portion C is not an intersection where the warp goes downward, the concave portion is less in comparison with the other concave portions A, B, and D, but a concave portion is formed in comparison with the knuckle top portion. Similarly, a recess C is formed on the auxiliary weft 6 '.
In the recess B, the auxiliary weft 4 'is located at the intersection of the warp 4 from the weft 3 below the auxiliary weft 4' and the warp 1 from the weft 5 below the auxiliary weft 4 '. It is the most depressed place that exists. Similarly, a recess B in which the auxiliary weft 8 ′ exists is also formed between the weft 7 and the weft 1. In this way, a concave portion in which the auxiliary weft is present is formed between the top portion of the first knuckle and the top portion of the second knuckle, thereby causing a height difference.
In this way, the first knuckle and the second knuckle having different shapes and the recesses A, B, C, and D having different shapes are formed on the upper surface side surface. Further, as described above, the recesses have different depths and shapes, and the recesses are not formed in the same row direction as can be seen from the arrangement of symbols A to D in the design diagram of FIG.
