Description

【Technical Field】 【0001】 The present invention relates to Japanese-style clothing. 【Background Art】 【0002】 Conventional Japanese-style sewing products (kimonos, yukatas, nagajuban, priest's robes, etc.) are all sewn by hand, or by a sewing machine, or by combining these means. Since all of these means require high technology, skills, experience, and knowledge, they cannot be processed (sewn) by just anyone immediately. In addition, since the number of personnel having these technologies, skills, experience, and knowledge is decreasing year by year, the search for and securing of personnel, education and training, and technology inheritance have become major issues. 【0003】 From such a background, for example, in Patent Document 1, there is a method for manufacturing a kimono in which an adhesive tape made of an acrylic resin agent with a polyester film as a core material is attached along the collar of the kimono, and a part called a half-collar is attached thereon. Also, in Patent Document 2, there has been proposed a method for manufacturing a kimono in which parts such as sleeves and collars and the body are joined using an adhesive tape / or a snap fastener, a chuck fastener. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 7-292506 【Patent Document 2】 Japanese Patent Application Laid-Open No. 61-160401 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 However, in the method of joining using adhesive tape described in Patent Documents 1 and 2, selecting and developing an adhesive tape that can provide sufficient adhesive strength is a major challenge. Furthermore, while Patent Document 2 states that hook-and-loop fasteners or zipper fasteners may be used in addition to adhesive tape, in that case, there are concerns about appearance problems such as increased thickness of the joined area and lifting of the joined area. 【0006】 In light of these circumstances, the present invention aims to provide Japanese clothing items that are excellent in peel strength and appearance quality, are easy to process, and have excellent productivity. [Means for solving the problem] 【0007】 To solve the above problems, the present invention has the following configuration. (1) Japanese clothing that includes at least a collar, front panel, sleeves, and back panel, The aforementioned Japanese clothing item includes at least a portion of an edge that has been folded over twice or more. A Japanese-style garment having a joint at least on a portion of the end of the folded structure, joined by at least one of the following methods: adhesive, bonding, or fusion, with the width of the joint being 0.3 to 1.5 cm. (2) The Japanese clothing item described in (1) above, wherein at least one of the following is included: the cuff, collar lining, sleeve opening, front panel lining, and hem, and the end of the fabric edge is folded over two or more times. (3) The Japanese clothing item as described in (1) or (2) above, wherein the joint is joined by at least one of pressure-sensitive double-sided tape or thermoplastic hot melt tape. (4) Japanese clothing items as described in any of (1) to (3) above, in which the collar, sleeves, back center, side seams, and front panels are joined by machine sewing. [Effects of the Invention] 【0008】 This invention provides traditional Japanese clothing that is excellent in strength and appearance, easy to process, and offers high productivity. [Brief explanation of the drawing] 【0009】 [Figure 1a] Figure 1a is a front view diagram illustrating the kimono, a type of traditional Japanese clothing. [Figure 1b] Figure 1b is a reverse view illustrating a kimono, one of the traditional Japanese clothing items. [Figure 2a] Figure 2a is a schematic diagram showing the edge of the fabric. [Figure 2b] Figure 2b is a schematic diagram showing an example of a folded structure at the edge of the fabric. [Figure 2c] Figure 2c is a schematic diagram showing an example of a folded structure at the edge of the fabric. [Figure 2d] Figure 2d is a schematic diagram showing an example of a folded structure at the edge of the fabric. [Figure 3] Figure 3 is a schematic diagram showing a cross-section of the joint. [Modes for carrying out the invention] 【0010】 The Japanese clothing items in this disclosure include at least a collar, a front panel, sleeves, and a back panel, and at least a portion of the edge has a structure in which the edge of the fabric is folded over two or more times. Taking the kimono in Figures 1a and 1b as an example, 100 in Figure 1a is the collar, 101 in Figure 1a is the front panel, 102 in Figure 1a is the sleeve, and 103 in Figure 1b is the back panel. Furthermore, Figures 1a and 1b illustrate examples such as collar attachment (Figure 1a 1), collar facing (Figure 1a 2), sleeve attachment (Figure 1a 3), cuff (Figure 1a 4), sleeve swing (Figure 1a 5), ​​center back (Figure 1b 6), side seam (Figure 1a 7), front panel attachment (Figure 1a 8), front panel facing (Figure 1a 9), and hem (Figure 1a 10), but at least a part of the Japanese clothing item will have a structure where the fabric edge is folded over two or more times. Here, the fabric edge refers to the cut edge of the fabric, for example, as shown in Figure 2a 11. 【0011】 In this disclosure, the end of the folded structure in which the edge of the fabric is folded back two or more times is preferably included in at least one of the following: the collar (e.g., 2 in Figure 1a), the cuff (e.g., 4 in Figure 1a), the sleeve opening (e.g., 5 in Figure 1a), the front panel (e.g., 9 in Figure 1a), and the hem (e.g., 10 in Figure 1a). In Japanese clothing, there are parts where cut parts are joined together, for example, as explained using Figures 1a and 1b, such as the collar attachment (1 in Figure 1a), the sleeve attachment (3 in Figure 1a), the center back (6 in Figure 1b), the side seam (7 in Figure 1a), and the front panel attachment (8 in Figure 1a). In these cases, the joints may be joined by machine sewing for reasons such as the need for greater strength in the joined parts and the long joining distance, and this is one of the preferred embodiments in the Japanese clothing of this disclosure. On the other hand, in order to avoid the seams being visible on the outside, it is preferable that at least one of the ends of the collar (e.g., 2 in Figure 1a), cuffs (e.g., 4 in Figure 1a), sleeve openings (e.g., 5 in Figure 1a), front panels (e.g., 9 in Figure 1a), and hems (e.g., 10 in Figure 1a) have the structure in which the fabric edge is folded over two or more times in this disclosure, and it is more preferable that all of them have this structure. 【0012】 Next, the folded structure will be explained using diagrams, but it is not limited to these. Figure 2a shows an example of cut fabric, Figure 2b shows an example of a structure where the fabric edge is folded once, Figure 2c shows an example of a structure where the fabric edge is folded twice, and Figure 2d shows an example of a structure where the fabric edge is folded three times. In other words, in this disclosure, a structure where the fabric edge is folded two or more times refers to a structure like those in Figures 2c and 2d. Note that in the case of the fabric edge as it is cut (11 in Figure 2a) or the fabric edge of a structure folded once (11 in Figure 2b), the fabric edge is exposed, so there is a concern that the threads that make up the fabric may fray or fall off from the fabric edge. For this reason, a structure where the fabric edge is folded two or more times (Figure 2c or Figure 2d) is preferred. While there is no particular limit to the number of folds required to prevent fraying or shedding of the fabric edges, a two-fold structure is preferable because fewer folds result in less fabric thickness in the folded areas, improved workability, and a better wearing experience. 【0013】 In addition, the Japanese-style clothing of the present disclosure has a joint portion joined by at least one method of adhesion, adhesion, or fusion at least partially at the end of the folded structure. For example, when described using FIG. 3, the joint portion 13 joined by 12 in FIG. 3 corresponds. Here, adhesion includes, but is not limited to, a method of joining using an adhesive. In adhesion, there are physical adhesion where the adhesive penetrates the unevenness on the surface of the fabric and the fabrics are adhered to each other, scientific adhesion where the adhesive and the fabric undergo a chemical reaction to bond and adhere, and adhesion by physical interaction where the adhesive and the fabric adhere closely and utilize the electrical attraction between molecules. In the present disclosure, as long as the fabrics are adhered to each other, it is not particularly limited. Generally, an adhesive is liquid before adhesion and has the characteristic of solidifying after adhesion and adhering strongly. 【0014】 In addition, adhesion includes, but is not limited to, the contact and joining of a sticky substance with another substance. Generally, adhesion refers to the state where objects are adhered to each other using an adhesive for a short time and can be peeled off. Since the adhesive is sticky both before and after adhesion and its physical properties do not change, it can be easily peeled off and reattached. Examples of general adhesive products include tape and seal. 【0015】 In addition, fusion includes, but is not limited to, a method of joining by melting the fabric using heat, adhering them, and cooling and solidifying them. It is also called heat fusion or welding. Specifically, by heating the fabric adhesion surface to a high temperature, the fabric is melted and softened. Next, the heated fabrics are overlapped and pressure is applied to adhere the fabrics to each other. Finally, that portion is cooled to be solidified and firmly joined. This technique is characterized by obtaining high adhesion strength because the fabric melts and integrates by heat. It is also environmentally friendly because it does not use chemical substances or solvents such as adhesives, and it has the characteristic that it is possible to adhere even large fabrics or those with complex shapes. However, it requires fusion equipment and electricity, and depending on the type of equipment, special skills, techniques, experience, and knowledge may also be required. 【0016】 The aforementioned joints are preferably joined by at least one of pressure-sensitive double-sided tape or thermoplastic hot-melt tape. At different ends, or at the same end, they may be joined by both pressure-sensitive double-sided tape and thermoplastic hot-melt tape. Pressure-sensitive double-sided tape in this disclosure includes, but is not limited to, double-sided tape that exhibits adhesive strength when pressure is applied. These tapes generally use pressure-sensitive adhesives, which can be bonded with only light pressure and exhibit adhesive strength relatively quickly when pressure is applied. Therefore, they are preferred because they do not require waiting for drying or curing like liquid adhesives and can be used on a variety of materials. The pressure-sensitive adhesive in this disclosure is not particularly limited, but preferred pressure-sensitive adhesives include acrylic polymers, which have excellent weather resistance and heat resistance and can bond to a wide range of materials, and are used in industrial and household tapes; rubber polymers, which have high initial adhesive strength and are easy to bond to materials with low surface energy; and silicone polymers, which have high temperature resistance, good adhesion to silicone materials, and resistance to mold and fungi. 【0017】 Furthermore, in this disclosure, thermoplastic hot melt refers to a type of adhesive that melts and adheres when heated and solidifies and sets when cooled. Thermoplastic hot melt tape includes, but is not limited to, a tape made by applying thermoplastic hot melt to a base fabric. Thermoplastic hot melt tape is preferred because it exhibits adhesive strength immediately when heated and solidifies and sets when cooled. In addition, many thermoplastic hot melts contain little to no organic solvents or volatile organic compounds, making them environmentally friendly and preferable because they can be used on a variety of materials such as plastics, metals, glass, rubber, and wood. In this disclosure, the type of thermoplastic hot melt is not particularly limited, but examples of preferred thermoplastic hot melts include polyurethane resins with excellent elasticity and flexibility, polyester resins with high durability and suitable for bonding metals and plastics, polyamide resins with excellent heat resistance and chemical resistance, and polyolefin resins suitable for difficult-to-bond materials such as polyethylene and polypropylene. 【0018】 In addition, in the joining means in the present disclosure, joining means using a pressure-sensitive double-sided tape and joining means using a thermoplastic hot melt tape are preferable, but are not limited thereto, and any means may be used. However, thermoplastic hot melt tapes tend to require equipment and devices for heating and pressurization, as well as techniques, skills, experience, and knowledge for handling such equipment. Therefore, compared with pressure-sensitive double-sided tape means, there are more restrictions. For these reasons, in the present disclosure, it is more preferable to use a pressure-sensitive double-sided tape that does not require special equipment, heat, energy, etc., and also does not require special techniques, skills, experience, knowledge, etc. associated with processing. 【0019】 In addition, the joint in the present disclosure refers to the portion where the fabric body and the folded fabric are joined in the structure where the fabric edge is folded back (for example, 13 in FIG. 2c). When the joining means is other than a tape, the width of the joint is measured at the point closest to the fabric edge (16 in FIG. 3) and the point farthest from the fabric edge (17 in FIG. 3) in the joint, and the difference (15 in FIG. 3) is obtained. Specifically, it can be obtained by the method described in the examples. When the joining means is a tape, for example, in the case of the joining means using the above-described pressure-sensitive double-sided tape or thermoplastic hot melt tape, the width of the tape is the width of the joint. The width of the joint is preferably 0.3 to 1.5 cm. The width is preferably 0.3 cm or more, and more preferably 0.4 mm or more. In the above range, the adhesive strength is improved and the workability is also excellent. Also, it is preferably 1.5 cm or less, and more preferably 1.0 cm or less. In the above range, the workability is also excellent and the texture of the joint surface is flexible. That is, by being within the above range, it is preferable in terms of excellent balance in adhesive strength, workability, appearance quality, texture, etc. 【Examples】 【0020】 Next, the present disclosure will be specifically described with reference to examples. The contents of each item shown in the examples and comparative examples are as follows, but the present disclosure is not limited thereto. Furthermore, each physical property value described in the text or examples was measured using the following methods, and the evaluation was performed as described below. 【0021】 (1) Number of times the edge of the fabric is folded The number of times the fabric edge is folded refers to the number of times the fabric edge is folded. In this context, the fabric edge refers to the cut edge of the fabric (11 in Figure 2a). To illustrate with the diagrams, Figure 2b shows a structure where the fabric edge is folded once, Figure 2c shows a structure where the fabric edge is folded twice, and Figure 2d shows a structure where the fabric edge is folded three times. 【0022】 (2) Width of the joint A straight line was drawn from the edge of the fabric to the point closest to the edge at the joint (16 in Figure 3). This line was then extended to identify the point furthest from the edge (17 in Figure 3), and the difference (15 in Figure 3) was calculated. If tape was used for joining, the tape width was used. Ten points were randomly selected from the joint, measured in units of 0.01 cm, and the average was taken, rounded to one decimal place. If there were multiple ends, the above measurements were performed at the joints of each end, and these measurements were averaged in the same manner. 【0023】 (3) Peel strength This indicates the strength of the joint measured according to JIS L 1093(2011)7.1.1 A-1 method. 【0024】 (4) Appearance Quality The appearance of the ends was visually evaluated. It was rated on a three-point scale: ◎ (best), ○ (average), and × (poor). 【0025】 (5) Texture The thickness and texture of the edges were evaluated by touch. The evaluation was based on three levels: ◎ (best), ○ (average), and × (poor). 【0026】 (6)Special skills / techniques We evaluated whether or not special skills or techniques were required in the processing. We indicated required skills or techniques with ×, unnecessary skills with ○, and intermediate skills with △. 【0027】 (7)Special equipment We evaluated whether or not special equipment is required for processing. "Required" is indicated with ×, and "Not required" with ○. 【0028】 (8) Workability We evaluated the workability during processing. The evaluation was based on three levels: ◎ (extremely easy to process = excellent workability), ○ (easy to process = good workability), and × (difficult to process = poor workability). 【0029】 (9) Processing time required The processing time required to process a 1m length is shown in seconds. A short processing time indicates good work efficiency. 【0030】 [Example 1] As shown in Figure 2c, the edges of a 100% polyester fabric were folded twice, and the joint was joined with 0.3 cm wide pressure-sensitive double-sided tape. A pressure of 980 Pa was applied and left for 1 minute. The pressure-sensitive adhesive tape used had a nonwoven fabric base coated with an acrylic adhesive and was capable of adhering at pressures of 980 Pa or higher. Five of these samples were prepared, and a peel test was performed on the joint. As a result, the peel strength was 21.8 N / 2.54 cm, and both the appearance quality and texture were excellent, requiring no special skills, techniques, or equipment. This edge was applied to the cuffs, collar seams, sleeve flaps, front panels, and hems, and the collar attachment, sleeve attachment, back center, side seams, and front panel attachment were joined by machine sewing to finish the Japanese clothing. This resulted in a Japanese clothing product with excellent productivity. 【0031】 [Example 2] As shown in Figure 2c, the edges of a 100% polyester fabric were folded twice, and the joint was joined with 0.5 cm wide pressure-sensitive double-sided tape. A pressure of 980 Pa was applied and left for 1 minute. The pressure-sensitive adhesive tape used had a nonwoven fabric base coated with an acrylic adhesive and was capable of adhering at pressures of 980 Pa or higher. Five of these samples were prepared, and peel tests were performed on the joints. As a result, the peel strength was 23.2 N / 2.54 cm, and both the appearance quality and texture were excellent, requiring no special skills, techniques, or equipment. These edges were applied to the cuffs, collar seams, sleeve flaps, front panels, and hems, and the collar attachment, sleeve attachment, back center, side seams, and front panel attachment were joined by machine sewing to finish the Japanese clothing. This resulted in a Japanese clothing product with excellent productivity. 【0032】 [Example 3] As shown in Figure 2c, the edges of a 100% polyester fabric were folded twice, and the joint was joined with 1.5 cm wide pressure-sensitive double-sided tape. A pressure of 980 Pa was applied and left for 1 minute. The pressure-sensitive adhesive tape used had a nonwoven fabric base coated with an acrylic adhesive and was capable of adhering at pressures of 980 Pa or higher. Five of these samples were prepared, and peel tests were performed on the joints. As a result, the peel strength was 23.3 N / 2.54 cm, and both the appearance quality and texture were excellent, requiring no special skills, techniques, or equipment. These edges were applied to the cuffs, collar seams, sleeve flaps, front panels, and hems, and the collar attachment, sleeve attachment, center back, side seams, and front panel attachment were joined by machine sewing to finish the Japanese clothing. This resulted in a Japanese clothing product with excellent productivity. 【0033】 [Example 4] As shown in Figure 2c, the edges of a 100% polyester fabric were folded twice, and the joint was bonded with a 0.5 cm wide thermoplastic hot-melt tape. A pressure of 1961 Pa at 120°C was applied and left for 1 minute. A single-layer urethane-based hot-melt double-sided adhesive tape capable of bonding at 120°C and 1961 Pa was used as the thermoplastic hot-melt tape. Five of these samples were prepared, and a peel test was performed on the joint. The results showed a peel strength of 25.3 N / 2.54 cm, and both the appearance quality and texture were excellent. However, it required special skills, technology, and equipment, and although it was finished into a Japanese-style garment as described above, the productivity was lower compared to Examples 1-3. 【0034】 [Example 5] As shown in Figure 2d, the edges of a 100% polyester fabric were folded three times, and the joints were joined with 0.5 cm wide pressure-sensitive double-sided tape. A pressure of 980 Pa was applied and left for 1 minute. The pressure-sensitive adhesive tape used had a nonwoven fabric base coated with an acrylic adhesive and was capable of adhering at pressures of 980 Pa or higher. Five of these samples were prepared, and peel tests were performed on the joints. As a result, the peel strength was 22.2 N / 2.54 cm. Although no special skills, techniques, or equipment were required, and productivity was good, the thickness was noticeable from the outside due to the folded edges, resulting in inferior appearance quality compared to Example 2. Similarly, although the fabric was finished into a Japanese-style garment as described above, the resulting garment had a rougher, stiffer texture. 【0035】 [Comparative Example 1] As shown in Figure 2b, the edge of a 100% polyester fabric was folded once, and the joint was bonded with 0.5 cm wide pressure-sensitive double-sided tape. A pressure of 980 Pa was applied and left for 1 minute. The pressure-sensitive adhesive tape used had a nonwoven fabric base coated with an acrylic adhesive and was capable of bonding at pressures of 980 Pa or higher. Five of these samples were prepared, and peel tests were performed on the joints. As a result, the peel strength was 22.8 N / 2.54 cm, the texture was excellent, and no special skills, techniques, or equipment were required. Although it was possible to finish it as a Japanese clothing item as described above, the productivity was good, but the resulting Japanese clothing item had poor appearance quality due to fraying of threads at the fabric edges. 【0036】 [Comparative Example 2] As shown in Figure 2c, the edges of a 100% polyester fabric were folded twice, and the joint was bonded with 0.2 cm wide pressure-sensitive double-sided tape. A pressure of 980 Pa was applied and left for 1 minute. The pressure-sensitive adhesive tape used had a nonwoven fabric base coated with an acrylic adhesive and was capable of adhering at pressures of 980 Pa or higher. Five of these samples were prepared, and peel tests were performed on the joints. As a result, although no special skills, techniques, or equipment were required, the peel strength was poor at 15.2 N / 2.54 cm, and because the tape was too thin, the application and release paper removal processes were time-consuming. As described above, the resulting Japanese clothing items were finished in the same way, but the productivity was somewhat lower. 【0037】 [Comparative Example 3] As shown in Figure 2c, the edges of a 100% polyester fabric were folded twice, and the joint was bonded with 2.0 cm wide pressure-sensitive double-sided tape. A pressure of 980 Pa was applied and left for 1 minute. The pressure-sensitive adhesive tape used had a nonwoven fabric base coated with an acrylic adhesive and was capable of bonding at pressures of 980 Pa or higher. Five of these samples were prepared, and peel tests were performed on the joints. As a result, although no special skills, techniques, or equipment were required, and the peel strength was acceptable at 24.5 N / 2.54 cm, the wide tape width caused the bonded area to appear raised from the surface, resulting in an inferior appearance, a rough and stiff feel, and a time-consuming application process. Therefore, although the garments were finished as Japanese clothing as described above, the resulting garments were less productive. 【0038】 [Comparative Example 4] Five samples were prepared by folding the edges of 100% polyester fabric twice and joining them by hand stitching, and a peel test was conducted. As a result, the peel strength was 40.3 N / 2.54 cm, which was acceptable, and both the appearance quality and texture were excellent. However, it required special skills and techniques, took 800 seconds to process, and although it was completed as a Japanese-style garment without using tape, similar to Example 1, the resulting garment was extremely unproductive. 【0039】 [Comparative Example 5] Five samples were prepared by folding the edge of a 100% polyester fabric twice and joining them using a scoop sewing machine, and a peel test was conducted. As a result, the peel strength was 34.2 N / 2.54 cm without any problems, and the appearance quality and texture were excellent. However, when finished into a Japanese-style product in the same manner as in Example 1 without using tape, a Japanese-style product that requires special skills, techniques, and special equipment was obtained. 【0040】 【Table 1】 【0041】 【Table 2】 【Explanation of Signs】 【0042】 1: Collar attachment 2: Collar folding 3: Sleeve attachment 4: Cuff 5: Sleeve swing 6: Center back 7: Side seam 8: Lapel attachment 9: Lapel folding 10: Hem 11: Fabric edge 12: Joint location 13: Joint part 14: Folded fabric 15: Width of the joint part 16: Point closest to the fabric edge of the joint part 17: Point farthest from the fabric edge of the joint part 100: Collar 101: Front body 102: Sleeve 103: Back body 104: Lapel
