FIG. 1 is a diagram illustrating a patterned knitted lace 1 according to this embodiment.
As illustrated in FIG. 1, a patterned knitted lace 1 (hereinafter referred to as knitted lace 1) is a knitted lace used for at least part of clothing. For example, the knitted lace 1 is used for all or part of innerwear (underwear) for women. Women's innerwear includes foundation (basic underwear), lingerie (decorative underwear), and underwear.
This knitted lace 1 is, for example, a raschel lace of a warp knitted fabric knitted by a warp knitting machine such as a raschel machine. be done. A knitted lace 1 has a ground knitting structure 2 and a pattern part 6 knitted into the ground knitting structure 2.例文帳に追加The knitted lace 1 has a finished density of 90 courses/inch or more and 130 courses/inch or less, preferably 95 courses/inch or more and 120 courses/inch or less.

The ground knitting structure 2 is a ground knitting structure formed by connecting two adjacent basic patterns (basic patterns 12 to be described later) to each other. The base knitting structure 2 is, for example, a chain knitting structure, a tulle structure, an atlas structure, a power net structure, or the like. The ground knitting structure 2 of this example is a chain knitting structure and has a run stopping (fraying prevention) function.
Further, the ground knitting structure 2 includes a watermark portion 4 and a ground pattern 5. - 特許庁

FIG. 2 is an illustration for explaining the knitting structure of the patterned knitted lace 1. As shown in FIG. For convenience of explanation, the threads are spaced apart from each other, but the threads are actually in close contact with each other.
As illustrated in FIG. 2, the knitted lace 1 includes a chain stitch yarn 10, a basic structure 12 formed by the chain stitch yarn 10, an elastic yarn 20, an adhesive yarn 30, a jacquard yarn (not shown), and a handle. 6 and pattern threads (not shown).

The chain stitch yarn 10 is a knitting yarn that forms a basic structure 12 that is the basis of the ground knitting structure 2, in other words, a knitting yarn that forms a plurality of stitches into which the insertion yarn is inserted. The chain stitch yarn 10 is a yarn formed of synthetic fibers among chemical fibers, and is a single material yarn or a composite yarn. For example, when the chain stitch yarn 10 is a single material yarn (for example, filament yarn), it is formed of polyamide nylon (nylon), acrylic, polyester, or the like. In addition, when the chain stitch yarn 10 is a composite yarn, for example, the nylon yarn is covered with a heat-fusible elastic yarn, which is an elastic yarn that adheres to other yarns by melting the material due to heat, as a core yarn. Composite yarn. Moreover, the chain knitting yarn 10 may be a yarn containing functional fibers such as a contact warm feeling, a contact cold feeling, or an antibacterial and deodorant, or may be a single material yarn or a composite yarn. The material can be selected according to the purpose and effect to be added, such as acrylic fiber thread as a warming functional fiber thread, cupra fiber thread as a cooling functional fiber thread, antibacterial and deodorant, and the combination of composite materials is also appropriate. You can choose. As a method for compositing the conjugate yarn, for example, covering processing, air entangling processing, pliing and twisting processing, and other known compositing processing methods can be appropriately selected. The chain stitch yarn 10 of this example is a multifilament yarn made of nylon.
The thickness of the chain stitch yarn 10 is, for example, in the range of 20 dtex (digitex) or more and 78 dtex or less, preferably 33 dtex or more and 44 dtex or less. The thickness of the chain stitch yarn 10 in this example is 33 dtex.

The basic weave 12 is a knitted weave in which a plurality of chain stitches are continuous with the chain stitch yarn 10 . As illustrated in FIG. 2, the plurality of basic structures 12 include basic structures 12A to 12D and are arranged in parallel at regular intervals. For convenience of explanation, the basic organizations 12A to 12D are referred to as the basic organization 12 when there is no particular need to distinguish them. Two adjacent basic weaves 12 are positioned so that their chain stitches are adjacent to each other in the direction (wale direction) perpendicular to the direction in which the plurality of basic weaves 12 are arranged or the direction (course direction) in which the plurality of chain stitches are continuous. are placed in
In addition, the basic structure 12 has a run stopper 15 that connects two adjacent basic structures 12 . The run stopping portion 15 crosses from the chain stitch of one of the two adjacent basic designs 12 to the chain stitch of the other basic design 12 by the chain stitch yarn 10 forming the basic design 12, Two adjacent basic tissues 12 are connected. The cycle of the run stop portion 15 is, for example, 3 or more courses, preferably 3 or more and 20 or less courses, more preferably 3 or more and 9 or less courses, in the course direction of the basic tissue 12. More preferably, the cycle is 3 courses or more and 7 courses or less. Note that the run stopping portion 15 of this example connects two adjacent basic tissues 12 in a cycle of three courses. Note that the run stopping portion 15 is an example of a connecting portion according to the present invention.

The elastic thread 20 is an elastic thread that stretches in the longitudinal direction of the thread. The elastic thread 20 is, for example, a polyurethane elastic thread (so-called spandex), which is a polyurethane elastic thread that does not have heat-fusibility (the polyurethane elastic thread that does not have heat-fusibility is not a polyurethane stretch thread). sometimes called).
The elastic thread 20 is an insertion thread that is inserted into a plurality of stitches of the basic structure 12, and the elastic thread 20 of this example is inserted into each of the basic structures 12 (12A to 12D in FIG. 2) to form a plurality of strands. The stitches are inserted and arranged in the continuous direction (course direction). Thereby, the elastic thread 20 can stretch and contract the basic structure 12 in the course direction. As a result, the elastic yarn 20 imparts stretchability to the knitted lace 1, making it a stretch lace.
Also, the elastic yarn 20 is inserted into a plurality of chain stitches of the basic structure 12 while being tensioned by adjusting the delivery amount.
Also, the thickness of the elastic thread 20 can be appropriately changed depending on the elongation and stretching force. The thickness of the elastic thread 20 in this example is 234 dtex or more and 311 dtex or less.

The adhesive thread 30 is a thread obtained by forming an adhesive material, specifically, a heat-sealable material into a thread shape. Adhesive yarn exhibits a bonding function with other yarns when the material is melted by heat. For example, the adhesive thread 30 is a heat-sealable polyurethane elastic thread (heat-sealable polyurethane elastic fiber). Alternatively, the bonding thread 30 may be a composite thread including elastic thread that stretches in the length direction of the thread. For example, the adhesive thread 30 may be a composite thread in which an elastic core thread is covered with a covering thread.
The adhesive thread 30 is an insertion thread that is inserted into a plurality of stitches of the basic tissue 12. The adhesive thread 30 of this example is inserted into each basic tissue 12 (12A to 12D in FIG. 2) to form a plurality of strands. The stitches are inserted and arranged in the continuous direction (course direction).
The thickness of the adhesive thread 30 is, for example, in the range of 20 dtex (digitex) or more and 155 dtex or less, preferably 22 dtex or more and 78 dtex or less, and the thickness of the adhesive thread 30 in this example is 44 dtex.

A jacquard yarn is an example of an insertion yarn according to the present invention, and is an insertion yarn that is inserted into the chain stitches of the basic fabric 12 . The jacquard thread connects two adjacent basic weaves 12 to form the ground weave 2 with a lace pattern. Jacquard yarns are single-material yarns or composite yarns, in this case single-material yarns.
Also, when the jacquard yarn is a single-material yarn, it is, for example, a synthetic fiber or a regenerated fiber. When the jacquard yarn is a composite yarn, it is, for example, a composite yarn of natural fibers or regenerated fibers and synthetic fibers, or a composite yarn of synthetic fibers. Here, natural fibers are, for example, cotton, linen, silk, wool, etc., and regenerated fibers are, for example, rayon, cupra, polynosic, and the like. Synthetic fibers are, for example, acrylic, polyester, nylon, or polyurethane.
Also, the jacquard yarn may be a heat-sealable adhesive yarn, for example, a composite yarn in which a heat-sealable elastic yarn of polyurethane or a polyurethane elastic yarn is used as a core yarn and a nylon yarn is covered. There may be. As a result, fraying and tearing of the base knitted structure 2 can be prevented. As a method for combining the jacquard yarn, a known method such as covering, air entangling, or pliing and twisting can be appropriately selected, and the composite yarn is manufactured by the above-described method suitable for the conditions.
Further, the jacquard yarn may be a yarn containing functional fibers such as a contact warm feeling, a contact cold feeling, or antibacterial and deodorizing like the chain knitting yarn 10, or may be a single material yarn or a composite yarn. The material can be selected according to the purpose and effect to be added, such as acrylic fiber thread as a warming functional fiber thread, cupra fiber thread as a cooling functional fiber thread, antibacterial and deodorant, and the combination of composite materials is also appropriate. You can choose.

The pattern yarn is an insertion yarn that is inserted into the chain stitches of the basic structure 12 . The pattern yarn is positioned on the front side of the knitted lace 1 and is a yarn that forms a predetermined pattern. The pattern yarn is woven into the base knitting structure 2 illustrated in FIG. 1 to form the pattern portion 6 . The knitted pattern yarn makes the ground knitting structure 2 appear the contour, shading, or unevenness of the pattern motif depending on the thickness and density per unit area.

FIG. 3 is a diagram illustrating the details of the knitting structure of the patterned knitted lace 1. As shown in FIG. For convenience of explanation, the threads are spaced apart from each other, but the threads are actually in close contact with each other.
FIG. 3 is a diagram focusing on the A part of FIG. As illustrated in FIG. 3, the elastic yarn 20 and the adhesive yarn 30 are inserted into the chain stitches 11A to 11D of the basic fabric 12 in the direction from the chain stitch 11A to the chain stitch 11D in the course direction, and with the same insertion route. It's becoming That is, the elastic thread 20 and the adhesive thread 30 have the same insertion path at least in part. In addition, when the elastic thread 20 and the adhesive thread 30 are inserted in the same course direction, the insertion paths may be different from each other.
The adhesive thread 30 includes a curved portion 31 in which at least a portion of the adhesive thread 30 is curved while being inserted into the chain stitch 11 . The curved portion 31 is a portion that curves or bends at a gentle or steep bending angle in the course direction, the wale direction, or the thickness direction of the knitted lace 1 . The curved portion 31 is located, for example, at a position where the curvature or degree of bending of the adhesive thread 30 is changed.
In addition, the elastic yarn 20 includes a turning portion 21 in which the orientation of the elastic yarn 20 changed along the insertion path of the elastic yarn 20 while being inserted into the chain stitches 11 .
Focusing on the chain stitch 11A and the chain stitch 11B, the adhesive yarn 30 is in a state before the knitted lace 1 is stretched in the course direction, between the insertion source chain stitch 11A and the insertion destination chain stitch 11B. Bent in many positions. Specifically, the adhesive thread 30 is provided with one or more curved portions 31 between the turning portions 21A and 21B of the elastic thread 20 . Since the adhesive thread 30 of this example has a plurality of curved portions 31, the adhesive thread 30 is bent at more positions than the elastic thread 20.例文帳に追加Also, the bonding thread 30 is entirely bonded at the position where it contacts the elastic thread 20 .

Similarly, between the insertion source chain stitch 11B and the insertion destination chain stitch 11C, and between the insertion source chain stitch 11C and the insertion destination chain stitch 11D, the adhesive yarn 30 is located at more positions than the elastic yarn 20. is bent at Specifically, the adhesive thread 30 is provided with one or more curved portions 31 between the turning portions 21B and 21C of the elastic thread 20 and also between the turning portions 21C and 21D. Since the adhesive thread 30 of this example has a plurality of curved portions 31, the adhesive thread 30 is bent at more positions than the elastic thread 20.例文帳に追加Also, the bonding thread 30 is entirely bonded at the position where it contacts the elastic thread 20 .
That is, the adhesive yarn 30 is in a state before being stretched in the course direction in which a plurality of stitches are continuous between the stitches of the insertion source and the stitches of the insertion destination (the elastic yarn 20 and the adhesive yarn 30 are not stretched and are in a natural state ( In the non-stretched state)), the elastic thread 20 is entirely curved, and at least a portion thereof is adhered to the elastic thread 20 . Note that FIG. 3 has been described by focusing on the A portion of the basic structure 12A illustrated in FIG. For the entirety of 20 , the adhesive thread 30 is arranged in a loop with respect to the elastic thread 20 .
As described above, since the elastic thread 20 is bonded to the surface of the elastic thread 20 with the adhesive thread 30 that is in a wavy or undulating state, the surface of the elastic thread 20 has an irregular shape. An uneven shape is formed.

FIG. 4 is an enlarged photograph of the knitted lace of the example and an enlarged photograph of the conventional knitted lace. FIG. 4(A) is an enlarged photograph of the knitted lace of the example, and FIG. 4(B) is an enlarged photograph of the conventional knitted lace.
As illustrated in FIG. 4A, in the non-stretched state of the knitted lace 1 of the present example, the elastic yarn 20 is wavy or wavy with respect to the surface of the elastic yarn 20. You can confirm that it is attached.
Further, as illustrated in FIG. 4(B), in the non-stretched state of the conventional knitted lace, the elastic thread is bonded to the surface of the elastic thread 20 with the bonding thread 30 in a relatively straight state. I can confirm that.
As described above, in the knitted lace 1 of this embodiment, the surface of the elastic yarn 20 has an irregular uneven shape by bonding the curved adhesive yarn 30 to the surface of the elastic yarn 20 .

Next, a method for manufacturing the knitted lace 1 will be described with reference to FIG.
FIG. 5 is a flow chart for explaining the method of manufacturing the patterned knitted lace 1 (S10).
The knitted lace 1 of this embodiment is knitted by a front jacquard Russell knitting machine (hereinafter referred to as a front jacquard machine). Hereinafter, in the manufacturing method of this example, the knitted lace 1 is obtained by knitting the lace fabric using the front jacquard machine, dyeing the knitted lace fabric, and heat-treating the dyed lace fabric.
As illustrated in FIG. 6, in step 100 (S100), the operator causes the front jacquard machine to stretch the chain stitch yarn 10 to form the basic design 12 illustrated in FIG. Specifically, the front jacquard machine guides the chain stitch yarn 10 to the knitting needles by a base reed to form chain stitches for warp knitting, and forms a plurality of basic designs 12 by connecting a plurality of the formed chain stitches in the course direction. do. A plurality of basic structures 12 to be formed are arranged in parallel at equal intervals in the wale direction. Also, the chain knitting yarn 10 is crossed in a cycle of three courses, and the run stopping portion 15 is inserted to connect two adjacent basic structures 12.例文帳に追加

In step 102 (S102), the operator causes the front jacquard machine to insert the elastic yarn 20 into the chain stitches of the basic structure 12 formed by stretching the chain stitch yarn 10 . The front jacquard machine of this example, as illustrated in FIG. An elastic thread 20 is inserted into chain stitches of a basic structure 12 formed by stretching the thread 10.例文帳に追加Regarding the knitting density, the course density is 25 courses/inch or more and 55 courses/inch or less, preferably 35 courses/inch or more and 45 courses/inch or less. The course density in this example is 38 courses/inch.
Thus, by knitting in a stretched state at the time of knitting, a large elongation can be obtained after knitting. The ratio of the knitting density to the finished weaving density (finishing density) is the elongation. That is, when increasing the elongation, knitting is performed so that the finishing density is higher than the knitting density. In addition, in a knitted fabric with a large stretch ratio, the tightness of each loop of the basic structure 12 is weakened due to the large stretch ratio, so the texture (touch) of the fabric is soft.
Further, the elastic yarn 20 is fed less than the yarn feeding amount of the adhesive yarn 30 and is inserted into the chain stitch. In other words, the elastic thread 20 is inserted into the chain stitch in a state where the tension of the adhesive thread 30 is tensioned. As a result, by adjusting at least one of the cycle of inserting the elastic yarn 20 into the chain stitch, the thickness of the elastic yarn 20, and the amount of each yarn sent out, according to the target stretchability of the lace fabric, kickback (stretching) The force to return to the original state from the collapsed state) can be adjusted as appropriate.

In step 104 (S104), the operator causes the front jacquard machine to insert the bonding yarn 30 into the chain stitches of the basic design 12 formed by stretching the chain stitch yarn 10. As shown in FIG. In this example, as illustrated in FIG. 2, the adhesive thread 30 is inserted into the chain stitches in the course direction in which a plurality of chain stitches are continuous. Specifically, it is inserted along the same insertion path as the elastic thread 20 . The bonding yarn 30 is sent out in a yarn amount larger than the elastic yarn 20 and is inserted into the chain stitches. In other words, the adhesive thread 30 is inserted into the chain stitches in a looser tension than the elastic thread 20 .
By adjusting at least one of the cycle of inserting the adhesive yarn 30 into the chain stitches and the amount of each yarn feeding in accordance with the target elongation of the lace, the kickback and the twisted state after bonding are appropriately adjusted. be able to.

In step 106 (S106), the operator causes the front jacquard machine to insert the jacquard yarn and the pattern yarn into the chain stitches of the basic structure 12 formed by stretching the chain stitch yarn 10 . As a result, the watermark portion 4, the background pattern 5, and the pattern portion 6 illustrated in FIG. 1 are formed.
As described above, in steps S100 to S106, knitting and the like are performed on the same course by the knitting operation of the front jacquard knitting machine, and the lace ground before dyeing is manufactured. The produced lace fabric shrinks linearly in the course direction due to the shrinking force of the elastic yarn 20 after knitting. At this time, since the shrinkage rate of the adhesive thread 30 is smaller than the shrinkage rate of the elastic thread 20, the adhesive thread 30 is curved while following the elastic thread 20. - 特許庁In this example, the front jacquard machine is used for knitting, but the knitting is not limited to this, and can be realized by a back jacquard machine or the like.

At step 108 (S108), the operator dyes the knitted lace ground. In this example, the case of post-dyeing is explained, but the present invention is not limited to this, and the yarn may be pre-dyed.

In step 110 (S110), the operator heats the bonding thread 30 of the lace fabric to a temperature at which it melts to bond the bonding thread 30 to the elastic thread 20 (heat setting step). In the heat setting process, the bonding thread 30 arranged in a curved manner is bonded to the surface of the elastic thread 20 . As a result, unevenness is formed on the outer wall surface of the elastic thread 20 . The heat setting conditions for the heat setting step are 160° C. to 200° C. for 90 seconds or less, preferably 180° C. to 190° C. for 40 seconds to 80 seconds. Thereby, the worker can obtain the knitted lace 1 illustrated in FIG.

As described above, according to the knitted lace 1 of the present embodiment, by bonding the adhesive yarn 30 to the elastic yarn 20 in a curved state, the surface of the elastic yarn 20 has an irregular uneven shape. . Therefore, for example, when underwear including the knitted lace 1 is worn or washed, when an external force is applied and pulled, the adhesive yarn 30 adhered to the elastic yarn 20 is caught by the chain stitch 11, so that the elastic yarn It is possible to prevent the 20 from coming out of the basic structure 12 and from fraying. In addition, the slippage of the net is reduced, preventing the lace from twisting and maintaining the texture.
In addition, according to the knitted lace 1, by increasing the crossing of the chain stitch yarn 10 and inserting many run stopping portions 15, the cross stitch of the chain stitch yarn 10 is increased to form one basic structure. The yarn is in a bellows state in which it moves back and forth between the two wales, improving stretchability in the course direction. Furthermore, since the difference between the knitting density and the finished density at the time of knitting can be kept low compared to the case where the run stopping portion 15 is not provided, the tightness of the loops and the bursting strength of the basic structure 12 are also improved. In addition, since the bursting strength is improved, it becomes possible to use a thin thread for the chain stitch thread 10, and even if the number of the run stopping portions 15 increases, a clear pattern and a net can be expressed.

In addition, in order to further improve the effect of preventing the polyurethane from slipping out of the knitted lace 1 and the effect of preventing the net from slipping, it is possible to provide a knitted lace having more excellent physical properties by inserting an adhesive thread separately. In this case, the direction of insertion of each thread, the cycle of insertion, and the arrangement of the threads in front and behind the front and back of the lace are not limited.

Further, in the knitted lace 1, since the elastic yarn 20 and the adhesive yarn 30 are inserted into the basic structure 12 so as to follow the same insertion path in the same course direction, the sense of sheerness is not impaired.
Although the embodiments according to the present invention have been described above, the present invention is not limited to these, and various modifications, additions, and the like can be made without departing from the scope of the invention.

Next, each example will be described.

[Modification 1]
FIG. 6 is a detailed diagram of a knitting structure illustrating Modification 1 of the patterned knitted lace 1 of the present embodiment.
In the adhesive yarn 30 of the knitted lace of the above embodiment, the case where the thickness is generally uniform and is adhered to the elastic yarn 20 in a continuous state has been described, but the thickness is not limited to this, and the thickness is uneven. , or may be partially broken. As illustrated in FIG. 6 , the adhesive thread 30 includes a broken piece 302 where the adhesive thread 30 is partially broken, and a knot portion 304 where the adhesive thread 30 is partially raised.
The broken piece 302 is a piece of thread obtained by partially breaking the adhesive thread 30 . The broken piece 302 in this example is a piece of yarn that is broken by melting and deforming the heat-fusible yarn in the heat setting process. Note that the broken pieces 302 also include yarn pieces that are naturally broken by the fabric tension of the knitted lace 1 .
The knot portion 304 is a knot-like portion in which a portion of the adhesive thread 30 protrudes and protrudes. The knot portion 304 of this example is a partially raised portion caused by melting and deformation of the heat-fusible thread due to the heat setting process. Since the knot portion 304 is caught when the knitted lace 1 is stretched and contracted, it is possible to prevent the thread from coming off. In addition, when the knot portion 304 is provided at a position where the curved portion 31 exists, it is possible to more effectively prevent thread slippage in cooperation with the curved portion 31 .
In this way, the adhesive thread 30 forms the broken pieces 302 and the knots 304 on the surface of the elastic thread 20, and the surface of the elastic thread 20 can be irregularly uneven. can be strengthened and the thread can be prevented from coming off. The bonding thread 30 of Modification 1 may be a single material having heat-sealing properties, or a composite thread including threads that stretch in the length direction.

[Modification 2]
FIG. 7 is a diagram illustrating Modification 2 of the patterned knitted lace 1 of the present embodiment. FIG. 7A is an enlarged illustration of the elastic thread 20 and the adhesive thread 30 inserted into the basic tissue 12, and FIG. 7B is an enlarged view of the adhesive thread 30 unwound from the elastic thread 20. FIG. It is an example of illustration.
Although the case where the adhesive thread 30 in the knitted lace of the above embodiment is a heat-fusible thread has been described, the present invention is not limited to this, and may be, for example, a heat-fusible thread. Here, the heat bonding yarn is
For example, it is a yarn that is softened by heat during dyeing or heat setting, deformed in shape, and retains the deformed shape after cooling. For example, a heat-bonding yarn deforms its surface shape when it is woven with other yarns by performing a heat-setting process, and after cooling, the deformed shape is retained and bonded. In addition, the heat-bonded yarn deforms its shape by performing heat setting processing in a state where it enters the unevenness of the surface of other yarns and the gaps between yarns, and after cooling, the deformed shape is retained and adheres. . When the adhesive thread 30 is a thermal bonding thread, for example, it is a low melting point polyurethane thread, and in addition to being caught by the deformed shape held, the frictional force of the polyurethane thread itself is combined to prevent the elastic thread 20 from coming off. can be planned.

The bonding thread 30 of this example is a thermal bonding thread, and the surface shape of the bonding thread 30 is deformed according to the shape of another thread in contact with this bonding thread 30, and the deformed shape is maintained. Other yarn shapes include other yarn surface shapes and yarn arrangement shapes such as stitches of other yarns and intersections of other yarns. Specifically, the bonding yarn 30 has a shape that bites into the chain stitch yarn 12 in the shape after thermal processing due to tightening by the chain stitches formed by the chain stitch yarn 12 at the portion that contacts the chain stitch yarn 12. It is deformed and glued according to the In addition, as illustrated in FIG. 7(B), the adhesive thread 30 matches the surface shape of the elastic thread 20 in the shape after heat processing due to the difference in tension with the elastic thread 20 at the portion in contact with the elastic thread 20. The surface shape is deformed and adheres. Therefore, the adhesive thread 30 can have a surface shape corresponding to the surface shape of the elastic thread 20 and a surface shape of the adhesive thread 30 corresponding to the chain stitches of the chain stitch yarn 12. The yarn 20 can be provided with an irregularly textured surface profile.
In this way, the adhesive thread 30 forms an irregular surface with respect to the elastic thread 20, thereby preventing the thread from coming off. That is, the adhesive thread 30 may be a heat-fusible thread or a heat-fusible thread as long as at least a portion thereof adheres to the elastic thread 20 and as a result, the elastic thread 20 can be prevented from coming off. Note that the adhesive thread 30 is not limited to the heat-fusible thread or the heat-fusible thread, and any thread that adheres to the elastic thread 20 can be substituted. The thickness of the heat-fusible thread or the heat-fusible thread is approximately the same as the thickness of the elastic thread 20 or slightly thinner than the thickness of the elastic thread 20 . In addition, the force acting as an external factor that deforms the adhesive thread 30 is not limited to a thread that is deformed by heat such as a heat-sealing thread or a heat-sealing thread. The thread may be deformed by an external force or the like. Note that the bonding thread 30 of Modification 2 may be a single material having heat-sealability or a composite thread including threads that stretch in the length direction.
