Description

The present invention relates to clothing constructed using adhesives and a method for manufacturing clothing.

Conventionally, there is known a technique for joining the edges of a garment fabric with an adhesive instead of sewing the fabric together with a sewing machine. For example, Patent Document 1 proposes a technique for bonding a hot melt sheet when folding back the outer fabric, such as the hem of a swimsuit.
Furthermore, Patent Document 2 proposes a garment in which the tip of the folded-over edge of the fabric of the garment is further folded inward to hide the cut edge of the fabric, and the edge of the fabric is constructed by sandwiching and bonding a thermoplastic elastomer resin layer so as not to impede elasticity.

JP 2005-264394 A Japanese Utility Model Application Publication No. 7-40710

However, in the technology proposed in Patent Document 1, as shown in FIG. 12(a), the edge region C of the fabric A is simply folded over once, leaving the cut edges of the fabric exposed. Repeated wearing and washing causes the cut edges to fray, resulting in a poor appearance. In addition, the surface adhesion of the hot melt sheet T inhibits the elasticity of the fabric, resulting in a feeling of tension and a poor texture compared to the fabric's natural elasticity.
In addition, the garment proposed in Patent Document 2 has a triple structure in which the tip of the folded end region C of fabric A is further folded inward to hide the cut edge, as shown in Fig. 12(b), and therefore looks good after wearing and washing. However, the thermoplastic elastomer resin T' used so as not to inhibit the stretchability of the fabric is more expensive than general adhesive resins, and because fabric A and thermoplastic elastomer resin T' are laminated and bonded in a planar manner, the fabric edge hardens like a film, causing the fabric to lose its flexibility and giving it a poor feel.

The present invention has been made in consideration of the above, and provides a garment and a method for manufacturing the garment, which is configured so that the cut edges of the fabric are not exposed to prevent deterioration of appearance due to wearing and washing, and which has openings with a good texture without losing the flexibility and stretchability of the fabric even when the fabric is laminated and joined with an adhesive.

In order to solve the above-mentioned problems and achieve the object, the garment according to the present invention is made of a stretchable fabric and has an opening formed by a joint part formed by folding the end of the fabric twice to form a triple structure, the joint part being located at the end of the fabric and including a first folded region located in the middle of the triple structure, a second folded region connected to the first folded region and located outside the triple structure, a third region connected to the second folded region and located outside the triple structure, a first adhesive that is intermittently attached in a single or double row and bonds the first folded region to the second folded region, and a second adhesive that is intermittently attached in a single or double row and bonds the first folded region to the third region, and when the joint part is seen through in a plan view, the percentage of the area to which the first adhesive or the second adhesive is not attached is 50% or more of the area to which the first adhesive and the second adhesive are attached.

In addition, in the clothing of the present invention, the difference between the stress of the joint when stretched 50% in the longitudinal direction and the stress of the fabric when stretched 50% in a direction parallel to the longitudinal direction of the joint is within 50%.
In addition, in the clothing of the present invention, in the above invention, the application pattern of the first adhesive and the application pattern of the second adhesive are the same, and are applied at the same position when viewed through the joint.
In the garment according to the present invention, in the above invention, a fabric edge of the first folded region is in contact with a boundary line between the second folded region and the third region obtained by folding.

The method for manufacturing clothing according to the present invention includes the steps of: applying a first adhesive intermittently in a single or double row parallel to the edge of the fabric on the folded side of the second folded region adjacent to the first folded region; folding the first folded region and folding the first folded region and the second folded region together; applying a second adhesive intermittently in a single or double row parallel to the edge of the fabric on the side opposite to the folded side of the first folded region; folding the second folded region and folding the first folded region and the third region adjacent to the second folded region together; and bonding the first folded region and the second folded region together with the first adhesive, and bonding the first folded region and the third region together with the second adhesive.

According to the present invention, even when the fabric edges of the garment opening are joined using adhesive, it is possible to provide garments that look good and have a soft feel without losing the suppleness and stretchability of the fabric.

Below, a mode for carrying out the present invention (hereinafter, "embodiment") will be described with reference to the attached drawings. Note that the drawings are merely schematic.

(Embodiment 1)
Fig. 1 is a plan view showing a schematic diagram of a garment 1 according to embodiment 1. The garment 1 shown in the figure is an example of a short-sleeved undergarment top, and has openings 2, 3, and 4 for passing the head, arms, and torso.
The garment 1 is made of a stretchable fabric. For example, knitted fabric materials such as circular knitting and warp knitting provided as general clothing materials have the stretch required for implementing the present invention and are not limited thereto. In addition, even if it is a woven material, materials having stretchability for clothing are suitable for the present invention. The garment 1 can be applied to general underwear, innerwear with cups, as well as innerwear such as camisoles and tank tops, and is suitable. In addition, it can be applied to outerwear materials such as T-shirts and cut-and-sewn items and is not limited thereto.

Figure 2 is a cross-sectional view showing the configuration of the garment 1 according to embodiment 1, Figure 3 is a cross-sectional view showing the order in which the openings of the garment 1 according to embodiment 1 are configured from (a) to (c), and Figure 4 is a plan view and a cross-sectional view showing the openings of the garment 1 according to embodiment 1 in a see-through manner.

The garment 1 of the present invention has an opening formed by a joint part formed by folding back an end of a fabric twice to form a triple structure. The joint part is provided with a first folded-back region C1 located at the end of the fabric and in the middle of the triple structure, a second folded-back region C2 connected to the first folded-back region C1 and located outside the triple structure, a third region C3 connected to the second folded-back region C2 and located outside the triple structure, a first adhesive B1 provided intermittently in two rows and bonding the first folded-back region C1 and the second folded-back region C2, and a second adhesive B2 provided intermittently in two rows and bonding the first folded-back region C1 and the third region C3. When the joint part is seen through in a plan view, the proportion of the area to which the first adhesive B1 and the second adhesive B2 are not bonded is 50% or more of the area to which the first adhesive B1 and the second adhesive B2 are provided.
The joints of garment 1 are invisible because the end E of the fabric is folded inside the triple structure, resulting in a garment with a good appearance in which fraying of the end E of the fabric is not noticeable even after repeated wearing and washing of garment 1. Furthermore, in the region where first adhesive B1 and second adhesive B2 are applied, there are parts where the first adhesive or second adhesive is not fixed, so that a garment with a good feel can be obtained without losing the flexibility and stretchability of the fabric.

The width of the joints may be the width of the seam allowance or fold allowance required to construct a typical garment. For example, the openings 3 and 4 of the cuffs and hem of garment 1 may be folded back by about 10 to 30 mm. However, for the opening 2 of the collar, which is curved, if the width of the fold back is too large, it will cause pulling due to the difference between the inner and outer circumference of the curve, so it is preferable to keep it small, around 3 mm to 10 mm.

The first adhesive B1 and the second adhesive B2 are intermittently applied and arranged in a single or double row. The preferred size of the first adhesive B1 and the second adhesive B2 varies depending on the structure and thickness of the fabric A constituting the garment 1. A dot shape with a diameter of about 1.0 to 2.0 mm is likely to provide a relatively strong adhesive strength, but if the fabric A is thin, the adhesive may seep out to the front side of the fabric A and become noticeable, damaging the appearance, so a small adhesive within the range that provides the required adhesive strength is preferred. For example, in the case of an inner fabric with a thickness of about 0.5 to 0.8 mm, a diameter of about 0.6 to 1.0 mm is preferred because the first adhesive B1 and the second adhesive B2 are less likely to seep out to the front side of the fabric A. In the case of an even thinner fabric with a thickness of about 0.3 to 0.5 mm, a diameter of about 0.3 to 0.6 mm is preferred because the first adhesive B1 and the second adhesive B2 are less likely to seep out to the front side of the fabric A.

In the garment 1, as shown in FIG. 4, the first adhesive B1 and the second adhesive B2 are circular in shape, but are not limited to this. Any shape may be used as long as the first adhesive B1 and the second adhesive B2 are repeatedly applied in an intermittent, separated state, and may be linear if not continuous, or may be a geometric shape such as a triangle, square, or ellipse, or may be a combination of these shapes.

The resins constituting the first adhesive B1 and the second adhesive B2 are preferably synthetic resins rather than natural resins, and among these, thermoplastic resins are more preferable. For example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, polytetrafluoroethylene, polyacrylic, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyethersulfone, polyetheretherketone, polyimide, polyamideimide, and other polymer compounds can be used without any particular limitation, and various types can be used.

The resin constituting the first adhesive B1 and the second adhesive B2 is preferably a reactive hot melt. When the resin is a reactive hot melt, it softens or melts and seeps into the gaps between the structures at the bonded portion, and after cooling and solidifying, it reacts with the surrounding moisture to promote cross-linking, forming a joint with excellent heat resistance and solvent resistance, and even a small amount of adhesive applied in a dot pattern can provide strong adhesive strength. If a resin that has elasticity after adhering to the fabric is used, it is possible to obtain clothing with a good texture without losing the flexibility and stretchability of the fabric.

When the garment 1 of the present invention is viewed through a plan view of the joint, it is important that the proportion of the area to which the first adhesive B1 and the second adhesive B2 are applied where the first adhesive or the second adhesive is not fixed is 50% or more. It is preferably 60% or more. There is no particular upper limit, but since the peel strength of the joint tends to weaken as the proportion increases, it is preferable that the proportion be approximately 90% or less in order to obtain a joint that can withstand repeated wearing and washing.

4, in the garment 1, the application pattern of the first adhesive B1 and the application pattern of the second adhesive B2 are the same, and when the joint is viewed through, the first adhesive B1 and the second adhesive B2 are applied at the same position. In this specification, the region M where the first adhesive B1 and the second adhesive B2 are applied (adhesive application region) refers to the region where the first adhesive B1 and the second adhesive B2 are applied, and means an area (M=W×L) represented by the product of the outermost width W where the first adhesive B1 and the second adhesive B2 are applied and the repetition pitch L where the first adhesive B1 and the second adhesive B2 are intermittently applied. In the case where the diameter of the first adhesive B1 and the second adhesive B2 is very small and the pitch is random, etc., and it is difficult to specify the pitch, the length L is set to 3 cm, the average pitch is calculated from the number of adhesives applied thereto, and model diagrams such as those shown in Figures 4 to 10 are drawn, and the diameter of the adhesive is also measured for the adhesive applied in the 3 cm interval, the average is calculated, and the model diagram is drawn to calculate the adhesive application area. At this time, when actually measuring the application position and diameter of the adhesive, the first folded region C1, the second folded region C2, and the third region C3 that are fixed are actually measured by cutting them open with a razor like filleting a fish. In this way, even if the repeat pitch L1 of the first adhesive B1 and the repeat pitch L2 of the second adhesive B2 are different, an accurate model diagram obtained from the actual measured values of each is drawn, and the adhesive application area is calculated.

Also, as shown in Fig. 5, the application pattern of the first adhesive B1 and the application pattern of the second adhesive B2 are the same, but when the joint is viewed through, the first adhesive B1 and the second adhesive B2 may be applied with a relative shift in the longitudinal direction. In such a case, the adhesive application area M may be calculated as the product of the outermost width W where the first adhesive B1 and the second adhesive B2 are applied and the repetition pitch L where the first adhesive B1 and the second adhesive B2 are intermittently applied, as in the case of Fig. 4. In this case, if it is difficult to specify the pitch, the adhesive application area is calculated by setting the length L to 3 cm.
On the other hand, as shown in Fig. 6, there are cases where the application pattern of the first adhesive B1 and the application pattern of the second adhesive B2 are the same, but the first adhesive B1 and the second adhesive B2 are applied with a relative deviation in the width direction when the joint is viewed through. In such cases, the maximum width of the joint obtained by viewing through the first adhesive B1 and the adhesive B2 is W.

On the other hand, the adhesion area of the first adhesive B1 and the second adhesive B2 can be calculated from the shape when viewed in a plan view. In the first embodiment, the first adhesive B1 and the second adhesive B2 are approximately circular, so the adhesion area can be calculated from the diameter (maximum diameter of the approximately circular shape) and number of the first adhesive B1 and the second adhesive B2. Even if the application positions of the first adhesive B1 and the second adhesive B2 are shifted relative to each other, the adhesion area can be calculated from the diameter, amount of shift, and number of the first adhesive B1 and the second adhesive B2.

As described above, it is important that the ratio of the area not fixed by the first adhesive B1 or the second adhesive B2 is 50% or more in the adhesive application region M. As shown in Fig. 2, the first folded region C1 located on the inside of the triple structure of the joint is fixed to the second folded region C2 and the third region C3 from both sides by the first adhesive B1 and the second adhesive B2, respectively, and therefore is more likely to have its stretchability hindered than the second folded region C2 and the third region C3 on the outside of the triple structure.
For example, as shown in Fig. 9, if the application patterns of the first adhesive B1 and the second adhesive B2 are the same, but the application positions of the first adhesive B1 and the second adhesive B2 are significantly shifted in the longitudinal direction, the first folded region C1 located on the inside of the triple structure will be in a state in which the first adhesive B1 and the second adhesive B2 are continuously fixed in the longitudinal direction. As a result, as in the case of the tape-like adhesive of the conventional technology, the longitudinal stretchability of the joint is easily hindered, making it difficult to obtain the effects of the present invention. In such a case, the outermost width W and the repeat pitch L of the adhesive application region do not change, so that the proportion of the area of the adhesive application region M that is not fixed by the first adhesive B1 or the second adhesive B2 decreases. In the example shown in Fig. 9, the first folded region C1 is continuously bonded in the longitudinal direction with the first adhesive B1 or the second adhesive B2, and the ratio of the area in the adhesive-applied region M that is not bonded with the first adhesive B1 or the second adhesive B2 is small at 47.7%, which reduces the longitudinal stretchability of the joint, but if the first adhesive B1 and the second adhesive B2 are not continuously bonded in the longitudinal direction and gaps are formed, the ratio of the area in the adhesive-applied region M that is not bonded with the first adhesive B1 or the second adhesive B2 increases, which makes it easier for the joint to exhibit longitudinal stretchability, making it easier to achieve the effects of the present invention. That is, in the garment 1 of the present invention, by setting the ratio of the area in the adhesive-applied region M that is not bonded with the first adhesive B1 or the second adhesive B2 to 50% or more, it is possible to create an opening with a good texture without losing the suppleness and stretchability of the fabric.

On the other hand, as shown in FIG. 6, for example, if the application pattern of the first adhesive B1 and the application pattern of the second adhesive B2 are the same, but the application positions of the first adhesive B1 and the second adhesive B2 are significantly shifted in the width direction, the first adhesive B1 and the second adhesive B2 are not continuously fixed in the longitudinal direction as in the example shown in FIG. 9, and the longitudinal stretchability of the fabric is relatively less likely to be hindered. In the example of FIG. 6, the proportion of the area of the first adhesive B1 and the second adhesive B2 in the adhesive application region M becomes large, but the width W of the adhesive application region M also becomes large, so that the area of the part of the adhesive application region M where the first adhesive B1 and the second adhesive B2 are not fixed can be configured to be 50% or more. In other words, the effect of the present invention can be obtained.

In the garment 1 of the present invention, it is preferable that the difference between the stress at 50% elongation in the longitudinal direction 10 of the joint (see FIG. 4) and the stress at 50% elongation in the direction 11 parallel to the longitudinal direction of the joint of the fabric (see FIG. 4) is within 50%. By doing so, it is possible to obtain a garment with a good texture, in which the joint is not easily felt as a part that is difficult to stretch when actually touched and stretched. More preferably, the difference in stress at 50% elongation is within 25%, and more preferably within 20%.
Generally, the elongation property of a material for clothing is expressed by the elongation rate under a load of 1.5 kg, but when actually wearing a garment or inspecting its texture, such a load is rarely applied. When the actual texture is felt by hand, a load of about 50% is applied, so it is preferable that the difference in stress in this region be within the above range.

When comparing the stress at 50% elongation, the stretch direction of the fabric itself is set to a direction 11 parallel to the longitudinal direction 10 of the joints being compared, as shown in Fig. 4. In other words, the stretch direction is not necessarily the warp or weft direction of the fabric. It depends on the cut shape of the fabric constituting the garment 1 and the direction in which the fabric is cut.
The method for measuring the stress at 50% elongation is based on the grab method for elongation described in JIS-L-1096 (2010). If a sample of the desired size cannot be obtained due to the design of the garment 1, the size of the sample may be reduced to 5 cm in width and 10 cm in length, and the measurement may be performed with a gripping distance of 5 cm. In measuring the stress at the joint, the sample may be taken by aligning the joint with the fabric area connected to the joint. It is important that the joint is gripped when gripping with the tensile tester, and the sample is gripped and tested at a position where the gripping end and the fold end coincide as much as possible.

As described above, when the garment 1 of the present invention is viewed through a plan view of the joint, it is important that the proportion of the area of the region M where the first adhesive and the second adhesive are applied (adhesive application region) where the first adhesive B1 or the second adhesive B2 is not fixed is 50% or more. By doing so, it becomes easier to keep the difference between the stress at 50% elongation in the longitudinal direction 10 of the joint and the stress at 50% elongation in the direction 11 parallel to the joint of the fabric within 50%, and the texture can be improved.

In the garment 1 of the present invention, the application pattern of the first adhesive B1 and the application pattern of the second adhesive B2 are the same. In order to fix the opening of the garment 1, which has a triple structure, without excess fabric, it is necessary to fix the first folded region C1 and the second folded region C2, and the first folded region and the third region C3, respectively, with the first adhesive B1 and the second adhesive B2, but it is not necessary for the two to be in the same pattern. For example, the first adhesive B1 may be applied in a single row, and the second adhesive B2 may be applied in a double row, and the repeat pitch may be different, or the diameter may be different. However, if the application patterns of the first adhesive B1 and the second adhesive B2 are different, the adhesive and the fabric are laminated, and the thick parts and the non-thick parts tend to be irregular, resulting in an unnatural uneven feeling, so it is preferable that the application patterns are the same. In addition, it is preferable that the application patterns are the same in terms of simplifying the manufacturing process.

In the garment 1 of the present invention, it is preferable that the end E of the fabric in the first folded region C1 is in contact with the inside of the fold line F, which is the boundary line between the second folded region C2 and the third region C3 obtained by folding. In order to fold the end E of the fabric inside the fold, it is necessary to fold it twice, but it is not necessary to make the width of the two folds, i.e., the width of the first folded region C1 and the width of the second folded region, the same. For example, the width of the second folded region C2 may be larger than that of the first folded region C1. However, if the widths of the first folded region C1 and the second folded region C2 are different, a portion of the joint will be a three-layer structure and a two-layer structure, which is likely to cause an uncomfortable uneven feeling, so it is preferable that the widths of the first folded region C1 and the second folded region C2 are the same. In other words, it is preferable that the end E of the fabric is in contact with the inside of the fold line F of the fabric obtained by folding.
Furthermore, in the case of the garment 1 of the present invention, where there are parts in the joint that are fixed with the first adhesive B1 and the second adhesive B2 and parts that are not fixed, the fiber bundle becomes a free end at the end E, and fiber dust and dust may fall off from this fiber bundle, resulting in a poor appearance. By having the end E of the fabric contact the inside of the fold line F of the fabric obtained by folding back, the progress of fraying of the end E of the fabric is suppressed, and the fall off of fiber dust and the generation of dust are suppressed, which is preferable.

Next, a method for manufacturing the garment 1 of the present invention will be described. The garment 1 is manufactured by applying a first adhesive B1 intermittently in a single or double row in parallel to the edge of the fabric on the folded surface A1 of the first folded region C1 located at the edge of the fabric or the second folded region C2 adjacent to the first folded region C1, folding the first folded region C1 and folding the first folded region C1 and the second folded region C2 together, and applying a first adhesive B1 to the surface A2 opposite to the folded surface A1 of the first folded region C1 or to the second folded region C2. It is manufactured by the steps of applying the second adhesive B2 intermittently in a single or double row in parallel to the edge of the fabric on the folded surface A1 of the third region C3 connected to C2, folding the second folded region C2 and folding the first folded region C1 and the third region C3 together, and bonding the first folded region C1 and the second folded region C2 with the first adhesive B1 and bonding the first folded region C1 and the third region C3 with the second adhesive B2.

The first adhesive B1 can be applied to the first folded region C1 or the second folded region C2, but when the second adhesive B2 is applied in the same application pattern as the first adhesive B2 and in the same position, it is preferable to apply it to the second folded region C2 as shown in FIG. 3(a). By applying the first adhesive B1 to the second folded region C2, it becomes easier to accurately configure the opening, and the effect of the present invention becomes easier to obtain. When the first adhesive B1 is applied parallel to the end E of the fabric on the first folded region C1, if the opening is configured with a curve such as a neckline, the end of the fabric will be stretched and folded in two due to the difference between the inner and outer circumferences of the curve, and the interval of the first adhesive B1 applied intermittently will also be stretched. Therefore, when applying the second adhesive B2 with the same application pattern as the first adhesive B1 later, it becomes difficult to apply it to the same position as the first adhesive B1. When the second adhesive B2 is applied in the same application pattern and in the same position as the first adhesive B2, applying the first adhesive B1 to the second folded region C2 that has a distance between it and the end E of the fabric makes it easier to apply the second adhesive B2 to the same position as the first adhesive B1.

The process of bonding the first folded region C1 to the second folded region C2, and the first folded region C1 to the third region C3 with the first adhesive B1 and the second adhesive B2, respectively, is preferably carried out by heat pressing. A flat-plate press or a roller press used in general clothing production can be used for the bonding process. The pressing temperature may be a temperature at which the first adhesive B1 and the second adhesive B2 soften and melt and penetrate the fabric, and is preferably around 70 to 160°C. The pressing pressure may be a pressure at which the softened and melted first adhesive B1 and second adhesive B2 penetrate the fabric, and is preferably around 0.01 to 0.4 MPa in actual pressure.

(Embodiment 2)
Fig. 11 is a diagram showing the configuration of a garment according to embodiment 2. The garment 5 shown in the figure is an example of an undergarment such as shorts, and has an opening 6 through which the torso passes, and openings 7 through which both legs pass. It goes without saying that the effects of the present invention can be obtained in embodiment 2 in the same way as in embodiment 1.

Up to this point, we have explained the form for carrying out the present invention, but the present invention should not be limited to the above-mentioned embodiment. For example, the present invention can be applied to the joints of openings of wearable textile products, such as hats, headbands, masks, and other headwear, arm covers, neck warmers, supports, belly warmers, and other cylindrical wearable products, and aprons, scarves, and other items that cover parts of the body.

Example 1
A garment 1 was produced as a general undergarment as shown in FIG. 1, made of bare jersey material of 84% nylon and 16% polyurethane. A triple-structure joint was formed at the neck opening 2 of the garment 1, with the widths of the first folded-back region C1, the second folded-back region C2, and the third folded-back region C3 each being 6 mm. As shown in FIG. 3, the joint was formed by applying a dot-like first adhesive B1 with a diameter of 0.8 mm (1.0 mm after bonding) to the folded-back surface A1 of the second folded-back region C2 parallel to the edge of the fabric, and folding back the first folded-back region C1. At this time, the first adhesive B1 was applied in two rows, the distance between the centers of the rows was 2.0 mm, and the longitudinal pitch of the rows was also 2.0 mm. A reactive polyurethane hot melt resin was used as the first adhesive. Next, the second adhesive B2 was applied to the surface A2 opposite to the folded surface of the first folded region C1, and the second folded region was folded to form an opening 2 having a triple-structure joint. As shown in FIG. 4, the second adhesive B2 was applied to the same position as the first adhesive B1 in a transparent manner with the same size, resin, and application pattern as the first adhesive B1. Next, a heat and pressure adhesive press was performed in a flat-plate adhesive press to obtain a test piece of Example 1 of the present invention. In Example 1, the width W of the adhesive application region M was 3.0 mm, and the pitch L was 2.0 mm. As the adhesive, a reactive hot-melt PU resin with a viscosity of about 12,000 mPa·s at 120°C was used. The obtained test piece was evaluated for the stress difference between the joint and the fabric at 50% elongation, and the tension and texture of the joint. The results are shown in Table 1. Regarding the tension and texture of the joints, those that were flexible and had no noticeable tension were marked with an O, and those that were bothersome in terms of flexibility and tension were marked with an X.

Example 2
As shown in Fig. 5, the application position of the second adhesive B2 was shifted in the longitudinal direction from the application position of the first adhesive B1. A test piece of Example 2 was obtained in the same manner as Example 1, except that the application was shifted by a length of one-third of the diameter of the adhesive. In Example 2, the width W of the adhesive application region M was 3.0 mm, and the pitch L was 2.0 mm.

Example 3
As shown in Fig. 5, the application position of the second adhesive B2 was shifted in the longitudinal direction from the application position of the first adhesive B1. A test piece of Example 3 was obtained in the same manner as Example 1, except that the application was shifted by a length of half the diameter of the adhesive. In Example 3, the width W of the adhesive application region M was 3.0 mm, and the pitch L was 2.0 mm.

Example 4
As shown in Fig. 6, the application position of the second adhesive B2 was shifted in the width direction from the application position of the first adhesive B1. The adhesive was applied with a shift of half the length of the diameter of the adhesive. At this time, the width W of the adhesive application region M viewed through the film was 3.5 mm. Otherwise, the test piece of Example 4 was obtained in the same manner as Example 1. In Example 4, the width W of the adhesive application region M was 3.5 mm, and the pitch L was 2.0 mm.

Example 5
As shown in Fig. 7, the application position of the second adhesive B2 was shifted from the application position of the first adhesive B1 by the same length as the diameter of the adhesive in the longitudinal direction and also by the same length as the diameter of the adhesive in the width direction. At this time, the width W of the adhesive application region M viewed through the film was 4.0 mm. Otherwise, the test piece of Example 5 was obtained in the same manner as Example 1. In Example 5, the width W of the adhesive application region M was 4.0 mm, and the pitch L was 2.0 mm.

(Comparative Example 1)
As shown in Fig. 8, a test piece for Comparative Example 1 was obtained in the same manner as in Example 1, except that a triple-layered joint was formed using hot melt tapes T1 and T2 as the adhesive. In Comparative Example 1, the width W of the adhesive application region M was 3.0 mm, and the pitch L was 30.0 mm.

(Comparative Example 2)
9, a test piece for Comparative Example 2 was obtained in the same manner as in Example 1, except that the application position of the second adhesive B2 was shifted by the length of the diameter of the adhesive in the longitudinal direction from the application position of the first adhesive B1. In Comparative Example 2, the width W of the adhesive application region M was 3.0 mm, and the pitch L was 2.0 mm.

(Comparative Example 3)
As shown in Fig. 10, the diameter of the first adhesive B1 and the second adhesive B2 was 1.4 mm (diameter 1.5 mm after bonding), the distance between the centers of the rows was 1.5 mm, and the longitudinal pitch of the rows was also 1.5 mm. The width W of the adhesive application region M viewed through the transparent glass was 3.0 mm. The longitudinal adhesive repeat pitch L was 1.5 mm. Otherwise, a test piece of Comparative Example 3 was obtained in the same manner as in Example 1.

The examples and comparative examples obtained as described above were evaluated, and the results are shown in Table 1.
In a plan view of the joint, the percentage of the area where the first adhesive B1 or the second adhesive B2 is not fixed to the area (adhesive application area M) seen through the area where the first adhesive and the second adhesive are applied is expressed as the porosity of the adhesive application area. As is clear from Table 1, in the examples of the present invention, the porosity of the adhesive application area M is 50% or more, so that the fabric does not lose its flexibility and a good texture can be obtained. In contrast, in the comparative examples, the porosity of the adhesive application area is less than 50%, so the fabric loses its flexibility and a tight feeling is felt.
