Description

[Technical Field]

[0001] This invention relates to a shirt that is comfortable to wear, has a good appearance, and is suitable for mass production due to a novel adhesive structure, and is particularly directed to casual T-shirts and polo shirts. [Background technology]

[0002] Generally, clothing is made by joining together multiple pieces of fabric cut according to a predetermined pattern to form a three-dimensional structure that conforms to the body. To achieve this three-dimensional structure, the joining lines of the fabric pieces are often curved, and the shapes of the joining edges are the same length but slightly different lines so that the joining parts have a three-dimensional shape. To join such curved joining edges three-dimensionally, sewing is performed using a sewing machine that is capable of curved joining.

[0003] In the case of fabric pieces that have been sewn, the edges and sewn areas of the joints are thick, which causes the fabric to feel rough and uncomfortable against the skin. Moreover, sewing is time-consuming and increases manufacturing costs. On the other hand, in recent years, adhesive bonding has been developed as an alternative to sewing, and this simpler and less costly bonding method has been introduced into the clothing manufacturing process.

[0004] Patent Document 1 discloses a short-sleeved T-shirt in which multiple fabric pieces are joined together with an adhesive, resulting in a thin joint, which is soft to the touch and easy to manufacture. The main body of the T-shirt is made of a tubular fabric knitted on a circular knitting machine. Specifically, a long tubular fabric is cut to the required length, and a collar cut in a concave arc shape is formed in the center of the top edge of the main body of the tubular body, sleeve connection edges that are cut in a J shape and an inverted J shape on the upper side of the tubular body to become armholes, and a shoulder line is cut between the collar cutout and the armholes.

[0005] Then, fabric pieces that form the sleeves are cut from the cut pieces. The fabric pieces that form the sleeves are roughly rectangular, and one short side of the sleeve is joined to the other short side by adhesive to form a tubular sleeve. One ring-shaped edge of the tubular sleeve becomes the main body connecting edge for the armhole of the main body. The main body connecting edge of this sleeve is cut to fit the shape of the armhole. In the main body portion, the cut shoulder lines are joined together to form shoulder seams, thereby forming ring-shaped armholes at the upper part of the body side and a collar opening at the top edge.

[0006] Next, adhesive is applied in a zigzag pattern with a predetermined width to the surface of the adhesive area of ​​the main body connecting edge of the sleeve.The adhesive-coated main body connecting edge is then inserted into the armhole of the T-shirt main body portion to overlap the adhesive areas, and then the two are temporarily fastened together for positioning.After the temporary fastening, a cylindrical press base is inserted into the sleeve, and the adhesive areas of the overlapping portions of the two fabric pieces are sandwiched between the cylindrical press base and a heating roller.The heating roller is then rotated around the cylindrical press base to heat and pressurize the entire overlapping area and bond it.Furthermore, the round collar part is joined to the collar opening in the same manner. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2018-159166 Summary of the Invention [Problem to be solved by the invention]

[0008] However, as described in Patent Document 1, applying liquid adhesive in a zigzag pattern to the adhesive area of ​​the curved cylindrical sleeve portion, and during the bonding process, accurately overlapping the adhesive area of ​​the cylindrical sleeve portion with the adhesive area of ​​the armhole to temporarily secure them, inserting a cylindrical press base into that part, and performing heat treatment while rotating a heating roller along the band-shaped area, are extremely time-consuming manufacturing processes and have been an obstacle to mass production. For mass production, it is more suitable to stack all of the bonding portions of the component parts on a flat press base, temporarily attach them, and then bond them together by applying high pressure and high heat in a flat press. However, while a flat press can be used to bond flat joints, it cannot be used to bond three-dimensional joints such as armholes.

[0009] The present invention was made to solve these problems of the past, and provides a shirt structure that eliminates the ring-shaped armhole itself from the shirt, thereby eliminating the three-dimensional joining part that would be required to glue a cylindrical sleeve to the armhole, making all joining parts flat, and allowing the use of a flat press machine for all joining processes of the shirt. [Means for solving the problem]

[0010] In order to achieve the above-mentioned objective, the characteristic configuration of shirt A according to the present invention (claim 1) has the following structure, which makes it possible to apply a flat press to all bonding processes. Shirt A, which is based on this invention, The garment is composed of a front body 10, a back body 20, each made of a free-cut fabric, and left and right shoulder and sleeve parts 30 arranged between the front body 10 and the back body 20, The front body 10 comprises a front collar cutout portion 11a constituting the front side of the collar cutout E provided at the center of the upper edge, a front sleeve cap portion 12 constituting the front side of the sleeve cap provided at the upper part of the side edge, a shoulder joining portion 13 provided between an end portion 11p of the front collar cutout portion 11a and an upper end 12p of the front sleeve cap portion 12, and a front side edge lower portion 16 between a lower end 12q of the front sleeve cap portion 12 and a hem 15, The back body 20 comprises, at its upper edge, a back collar cutout portion 21a which forms the back side of the collar cutout E, a back inclined joining portion 25 which extends from an end 21p of the back collar cutout portion 21a to a point 25q on the side edge of the back body 20 which is superimposed on the lower end 12q of the front sleeve cap portion 12 of the front body 10, and a back side edge lower portion 26 which is bonded to the front side edge lower portion 16 of the front body 10, The shoulder and sleeve part 30 includes a shoulder portion 31 and a sleeve portion 36. The shoulder portion 31 comprises a horizontal collar opening portion 31a on the upper side that constitutes the horizontal portion of the collar opening E, a shoulder joining portion 33 adhered to the shoulder joining portion 13 of the front body 10, a front sleeve cap joining portion 32 adhered to the front sleeve cap portion 12 of the front body 10, and a back inclined joining portion 35 adhered to the back inclined joining portion 25 of the back body 20, The sleeve portion 36 is a portion that extends integrally outward from the shoulder portion 31 from the line L2 connecting the lower end 32q of the front sleeve cap joining portion 32 and the lower end 35q of the back inclined joining portion 35, and is characterized by having an under-sleeve joining portion 36a in which the edges extending from the lower end 32q to the cuff 37 are joined together by adhesive.

[0011] Claim 2 (Fig. 1, Fig. 3) is a shirt A according to claim 1, The upper end 32p of the front sleeve cap joined portion 32 of the shoulder / sleeve part 30 is provided in the vicinity of the apex Pt of the sleeve cap, The shoulder joining portion 33 extending from the upper end 32p to the horizontal collar cutting portion 31a of the shoulder sleeve part 30 is characterized in that it is arranged to extend along the shoulder line L1 of the shoulder sleeve part 30 extending from the apex Pt of the sleeve cap to the horizontal collar cutting portion 31a.

[0012] Claim 3 (Figs. 7 to 16) shows a case where the round collar part 40 is composed of two parts, and in the shirt A of claim 1 or 2, The ring-shaped round collar part 40 is composed of a horseshoe-shaped front round collar part 41 and an arc-shaped back round collar part 42, The front round collar part 41 and the back round collar part 42 are characterized in that they are bonded at both ends to each other and also to the periphery of the collar opening E.

[0013] Claim 4 (Fig. 21, Fig. 22) is a case where the round collar part 40 is composed of one part, and in the shirt A described in claim 1 or 2, The ring-shaped round collar part 40 is configured in a C-shape, and the ends of the round collar part 40 are bonded together to form a ring shape, and are bonded around the collar opening E. [Effects of the Invention]

[0014] From the above, in the shirt A of the present invention, the shoulder portions 31 of the left and right shoulder sleeve parts 30 extending from the collar opening E are positioned between the shoulder joint portion 13 of the front body 10 and the back sloping joint portion 25 of the back body 20, thereby eliminating the ring-shaped armholes used in the past.

[0015] In such a shirt A, when the shoulder joining portion 33 and the front sleeve seam joining portion 32 connected thereto of the shoulder sleeve part 30 are overlapped on the adhesive application area R of the shoulder joining portion 13 of the front body 10 and the front sleeve seam joining portion 12 connected thereto, the shoulder joining portion 13 and the front sleeve seam joining portion 32 connected thereto are connected at their upper ends 12p, and the shoulder joining portion 33 and the front sleeve seam joining portion 32 are connected at their upper ends 32p, and by gathering and slightly deforming the shoulder sleeve part 30, the adhesive application areas R of both can be made flat. Similarly, by gathering and slightly deforming the shoulder and sleeve parts 30, the adhesive application area R of the back inclined joining portion 25 of the flat back body 20 is also superimposed on the back inclined joining portion 35 of the flat shoulder and sleeve parts 30, so that the adhesive application areas R of both can also be made flat. When the adhesive-applied area R of the front edge lower portion 16 of the flat front body 10 and the back edge lower portion 26 of the flat back body 20 are overlapped, this portion is also flat, and when the short side extending from the lower end 32q of the front sleeve-cap joined portion 32 of the sleeve portion 36 to the cuff 37 (one underarm joining portion 36a) and the adhesive-applied area R of the other underarm joining portion 36a extending from the lower end 35q of the back inclined joined portion 35 to the cuff 37 are overlapped, this portion also becomes flat. When the sleeve portion 36 is folded, the adhesive-applied area R of the sleeve portion 36 is connected flat to the overlapping portions on the body side (the front edge lower portion 16 and the back edge lower portion 26) at the lower end 12q of the front sleeve-cap joined portion 12 (the lower end 32q of the front sleeve-cap joined portion 32), and as a result, a flat press can be used for all of the bonding operations of the shirt A of this invention.

[0016] In addition, on the back body 20 side, the back side edge of the shoulder sleeve part 30 (back inclined joining portion 35) is deeply hollowed out so as to pass through the shoulder blades or their vicinity, making it easier for the wearer to move their arms and providing a comfortable fit.

[0017] As described in claim 2, the shirt A of the present invention has the shoulder joint portion 33 of the shoulder sleeve part 30 arranged to extend along the shoulder line L1, so that when viewed from the front, the shoulder joint portion 13 of the front body 10 is located on the wearer's shoulder and cannot be seen, and the front side of the shirt A has an excellent appearance that is no different from the appearance of a conventional shirt with armholes. Furthermore, by configuring the round collar part 40 in this way, the round collar portion can also be bonded using a flat press. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following describes the shirt A of the present invention with reference to the drawings. There are various types of shirt A, but this invention focuses on casual T-shirts and polo shirts. Figures 1 and 2 show a perspective view from the front and a perspective view from the back of an example of the shirt A of the present invention. The shirt A according to the present invention is composed of a front body 10, a back body 20, left and right shoulder and sleeve parts 30, and a round collar part 40, which is used as needed. The front body 10, back body 20, and left and right shoulder and sleeve parts 30 are cut according to a paper pattern, with the cut edges left raw. The material used is free-cut fabric. Free-cut fabric is a fabric that can be cut in any direction without fraying, has high stretchability in both the vertical and horizontal directions (four-way stretch effect), and also has the ability to maintain its shape. It is characterized by its ability to fit closely to the body without causing a feeling of pressure on the wearer, ensuring comfort even when worn for long periods of time. The material is typically a blend of polyester or nylon with spandex. These components are adhesively joined using a flat press, and in the drawings, the adhesive parts are indicated by the symbol S, the temporary fastening points by the symbol K, and the adhesive application area by the symbol R. The flat press is also indicated by a dashed line in the drawings and is designated by the symbol Hp.

[0020] As can be seen from Figure 3, the front body 10 has a concave arc-shaped front collar cutout 11a, which is the front part of the collar cutout E, formed in the center of its upper edge, and further has a front sleeve cap 12, which is the front part of the sleeve cap, formed in a J-shape and an inverted J-shape at the upper part of the side edge. The part from the lower end 12q of the front sleeve cap 12 to the hem 15 of the front body 10 is the lower front edge 16 of the front body 10. The part from the end 11p of the front collar cutout 11a to the upper end 12p of the front sleeve cap 12 is the shoulder joint part 13, which is formed in a gentle convex arc shape to match the curvature of the shoulder.

[0021] As can be seen from Figure 3, the upper half of the back body 20 is cut into an approximately trapezoidal or hat-shaped shape with the width decreasing towards the top edge, and a concave arc-shaped back collar cutout portion 21a, which is the back part of the collar cutout E, is formed in the center of the top edge. The oblique side of the trapezoidal or hat-shaped cut part is the back inclined joining part 25, and one side is cut to form a gentle S-shape and the other side to form an inverted S-shape so that it can be formed three-dimensionally to fit the curve of the back when glued.

[0022] The shoulder and sleeve parts 30 are cut symmetrically in pairs, left and right, and are composed of shoulder parts 31 and sleeve parts 36 that extend integrally from the shoulder parts 31. The sleeve parts 36 in Figure 3 are short sleeves. Although not shown, they can also be long sleeves. Since the shoulder and sleeve parts 30 are positioned between the front body 10 and the back body 20, the present invention naturally does not have ring-shaped armholes like the conventional example. The shoulder portion 31 is a portion that is bonded to the shoulder joining portion 13 of the front body 10 and the front sleeve cap portion 12 that follows this, as well as the back inclined joining portion 25 of the back body 20. The sleeve portion 36 is a portion that extends outward from a line L2, shown by a dashed line in Fig. 3, which connects the lower end 32q of the front sleeve cap joined portion and the lower end 35q of the back inclined joined portion 35. The vertex Pt of the sleeve cap is a point on the line L2, which is the boundary between the shoulder portion 31 and the sleeve portion 36, that is close to the intersection of the shoulder line L1, which is the fold of the shoulder / sleeve part 30 described later, and the upper end (switching point) 32p of the front sleeve cap joined portion.

[0023] The narrow upper edge of the shoulder portion 31 on the collar side is cut into a concave arc, forming the horizontal collar cutout portion 31a that constitutes the horizontal portion of the collar cutout E. The inner angle of the front end 31p of the horizontal collar cutout portion 31a on the front body 10 side is cut at an obtuse angle, while the inner angle of the back end 31q is cut at an acute angle, designed to create a three-dimensional neckline when assembled by gluing. The edge of the shoulder portion 31 that is glued to the shoulder joining portion 13 of the front body 10 is called the shoulder joining portion 33, and the edge that is glued to the front sleeve cap joining portion 12 is called the front sleeve cap joining portion 32. The transition point between the shoulder joining portion 33 and the front sleeve cap joining portion 32 is the upper end 32p of the front sleeve cap joining portion 32.

[0024] The shoulder bonded portion 33 is cut to the same length and in the same gentle concave arc shape as the shoulder bonding portion 13 to be bonded, so that it can be pressed flat. On the other hand, as can be seen from Figures 3 and 5, when the shoulder / sleeve part 30 is placed between the front body 10 and the back body 20, the front sleeve cap joined part 32 of the shoulder part 31, which extends from the transition point 32p of the shoulder joined part 33 toward the front body 10, is cut to form a gentle S-shaped curve, different from the curve of the front sleeve cap joined part 12. In other words, the length of the front sleeve cap part 12 and the length of the front sleeve cap joined part 32 are equal, but their linear shapes are different. This is to make the sleeve part 36 three-dimensional when assembled. In addition, as can be seen from Figure 5, the opening angle (inner angle) of the front sleeve cap joined part 32 relative to the shoulder joined part 33 is cut to be larger than the opening angle (inner angle) between the shoulder connection part 13 and the front sleeve cap part 12 so that the sleeve part 36 will be three-dimensional when assembled.

[0025] In the shoulder and sleeve parts 30, the back inclined joined portion 35 of the shoulder part 31, which is connected to the back inclined joined portion 25 of the back body 20, is cut to the same length as the back inclined joined portion 25, but is cut into a gentle concave arc shape along its entire length. In order to ensure the three-dimensional shaping of the back from the shoulder blades after bonding and assembly, the line shape is slightly different from that of the back inclined joined portion 25 of the back body 20. The bonding and assembly of this portion will be described later. The sleeve portion 36 is the portion beyond the line L2 connecting the lower end 35q of the back inclined joined portion 35 and the lower end 32q of the front sleeve cap joined portion 32.

[0026] The round collar part 40 is glued as needed. In this invention, the material for the round collar part 40 is a free-cut fabric. In this embodiment (Fig. 3), the round collar part 40 is made up of a horseshoe-shaped front round collar part 41 and an arc-shaped back round collar part 42 that fit the collar opening E. Of course, as will be described later, it is also possible to use a single round collar part 40 (Fig. 21).

[0027] Next, we will explain the adhesive used in this invention. The adhesive used to bond the component parts is an adhesive whose main component is at least one selected from polymers, prepolymers, and oligomers, which have a softening or melting temperature lower than the heat distortion temperature of the heat-deformable elastic yarn used in the component fabric pieces. With such an adhesive, when the fabric pieces to be bonded are overlapped and heat-treated, the adhesive softens or melts without thermally deforming the heat-deformable elastic yarn in the process of bonding the two fabric pieces, and the two fabric pieces are bonded without being damaged by the heat of the heat-deformable elastic yarn woven into the fabric pieces.

[0028] In this invention, adhesive is applied to the component parts in adhesive application regions R in multiple rows (three rows in FIG. 6) or zigzag lines (not shown) using an application device such as a dispenser. The adhesive application regions R are indicated by thick diagonal strips along the edge of each part. The adhesive is applied as appropriate during the assembly process, as will be described later.

[0029] - Assembling the front body 10 and shoulder / sleeve parts 30 (Figures 4 to 6) - As shown in Fig. 4, adhesive is applied to the left and right shoulder joining portions 13 and the front sleeve cap portion 12 of the front body 10. The portions to which the adhesive is applied are referred to as adhesive application regions R. Next, the shoulder joining portion 33 of the shoulder sleeve part 30 is overlapped on the adhesive application area R of the shoulder joining portion 13 of the front body 10. Since the shoulder joining portion 13 and the shoulder joining portion 33 have the same shape, they overlap without any discrepancies. After that, the shoulder joining portion 13 and the shoulder joining portion 33 are temporarily fastened together at multiple points. The temporary fastening is done by applying heat and pressure to parts using a heating device such as an iron to bond them together. The heated points are indicated by circles and are marked with the symbol K.

[0030] As described above, the shoulder joining portion 13 and the shoulder joining portion 33 overlap as they are, but the adhesive-applied area R of the front sleeve cap portion 12 of the front body 10 and the adhered area of ​​the front sleeve cap joined portion 32 of the shoulder / sleeve part 30 are slightly different in shape and also differ in opening angle, so they do not overlap in plan view. Therefore, after temporarily joining the shoulder joining portion 13 and the shoulder joining portion 33 as described above, the adhered area of ​​the front sleeve cap joined portion 32 is gradually overlapped on the adhesive-applied area of ​​the shoulder joining portion 13 while gathering the sleeve portion 36, and temporary joining is then performed. Figure 5 shows the state after the left shoulder joining part 13 and shoulder joining part 33, and the front sleeve cap part 12 and front sleeve cap part 32 are temporarily joined, followed by the right shoulder joining part 13 and shoulder joining part 33, and before the right front sleeve cap part 12 and front sleeve cap part 32 are temporarily joined. Once the left and right temporary joining is complete, the process moves to the actual heat bonding process for this part (Figure 6).

[0031] In this thermocompression bonding process, the temporarily fixed left and right shoulder joining parts 13 (shoulder joining parts 33) and front sleeve cap part 12 (front sleeve cap joining part 32 of shoulder / sleeve part 30 with gathers) become flat and can be placed on a flat press base. As a result, both parts can be bonded at once using a flat press machine Hp as shown in Figure 6. The flat press machine Hp is indicated by a dashed rectangular line, and the bonding parts are indicated by the symbol S.

[0032] - Assembling the round collar part 40 (Figures 7 to 14) - The round collar part 40 can be one piece or two pieces. First, the two-piece piece will be described. Adhesive is applied along the outer periphery of the rear surface of the horseshoe-shaped round front collar part 41 (FIG. 7). The thick diagonally shaded area is the adhesive application area R. This horseshoe-shaped rounded collar part 41 is then overlapped with the adhesive application area R around the periphery of the front collar cutout 11a of the front body 10 and the side collar cutouts 31a of the shoulder and sleeve parts 30, and temporarily secured in several places (Figure 8). Because the length of the arc of the rounded collar part 41 is shorter than the length of the front collar cutout 11a and the left and right side collar cutouts 31a, the entire rounded collar part 41 is temporarily secured to the front collar cutout 11a and the left and right side collar cutouts 31a. Because these temporarily secured parts are flat, they are bonded using a flat press Hp (Figure 9).

[0033] Next, adhesive is applied to the back surface of the rounded back collar part 42 along its outer periphery (Figure 10). After that, a portion (the center portion) of the adhesive-applied area R of the rounded back collar part 42 is overlapped and temporarily attached to the back collar cutout part 21a of the back body 20. Because the length of the rounded back collar part 42 is longer than the length of the back collar cutout part 21a, both ends of the rounded back collar part 42 protrude outward from the back collar cutout part 21a (Figure 11). Because this temporarily attached part is flat, it is then adhered using a flat press machine Hp (Figure 12).

[0034] - Assembling the back body 20 to the shoulder and sleeve parts 30 (Figures 13 to 17) - As shown in Figure 13, the back body 20, with the back round collar part 42 adhered to the back collar cutout part 21a, is placed between the two shoulder and sleeve parts 30 adhered to the front body 10, and the adhesive application area R of the protruding part of the back round collar part 42 is overlapped with the periphery of the side collar cutout part 31a of the shoulder and sleeve parts 30 and both end parts of the front round collar part 41, and the overlapped parts are temporarily fastened (Figure 14).

[0035] Next, adhesive is applied along the periphery of the left and right back inclined joining portions 25 of the back body 20. Then, the back inclined joining portions 35 are temporarily attached to the back inclined joining portions 25. However, in this state, the left and right back inclined joining portions 25 of the back body 20 and the back inclined joining portions 35 of the left and right shoulder / sleeve parts 30 are widely separated, making it impossible to temporarily attach them (Figure 14). Therefore, the back body 20 and shoulder / sleeve parts 30 are stretched to draw the back inclined joining portions 25 and the back inclined joining portions 35 closer to each other, and the to-be-adhered areas of the back inclined joining portions 35 are successively overlapped with the adhesive-applied areas R of the back inclined joining portions 25 to temporarily attach them. This process is carried out from the back round collar part 42 side toward the bottom ends 35q of the back inclined joining portions 35, until the entire length is temporarily attached (Figure 15). Once one step is completed, the other step is carried out.

[0036] After this temporary fastening is completed, the parts to be joined are released and the contraction force causes them to deform three-dimensionally, so the parts to be joined are clamped in a flat press Hp while maintaining their flat shape while still applying a pulling force, and the temporary fastening area is permanently bonded (Figure 16). After that, the shoulder and sleeve parts 30 are folded at the shoulder line L1 so that the back body 20 is positioned at the back of the front body 10 (Figure 17). Here, the shoulder line L1 is a straight line from the horizontal collar opening 31a of the shoulder / sleeve part 30 to the cuff 37, and passes through the highest ridge of the shoulder. The shoulder joining part 33 of the shoulder / sleeve part 30 runs along and close to this shoulder line L1. Therefore, the upper end (switching point) 32p of the front sleeve cap joining part 32 is located near the apex Pt of the sleeve cap. The flat pressing may be performed on the left and right temporary fastening areas separately as shown in the figure, or both temporary fastening areas may be flat pressed at the same time (not shown). At the end of pressing, the underarm and side portions of the sleeve portion 36 are not yet bonded (Figure 17).

[0037] - Assembly of sleeve part 36 and side part (Figure 18 to Figure 20) - Adhesive is applied along the side edges of the front edge lower portion 16 of the front body 10 and along the edge of the end portion (one of the underarm joining portions 36a) of the sleeve portion 36 leading to the front cuff 37 (Fig. 18). Thereafter, the adhesive-applied area R is folded back, and the joined portion of the back edge lower portion 26 of the back body 2 is overlapped and temporarily fastened onto the adhesive-applied area R of the front edge lower portion 16 of the front body 10. Similarly, the back edge of the sleeve 36 is temporarily joined to the adhesive-applied area R on the front side (the other underarm joining area 36a) (Fig. 19). These temporarily joined areas are flat, so they are bonded by applying heat and pressure with a flat press (Fig. 20). This completes the assembly of the shirt A of the present invention.

[0038] 1 and 2, the adhesive areas at the ends of the front round collar section 41 and back round collar section 42 of the round collar part 40, as well as the overlapping areas of the back collar cutout section 21a and the side collar cutout section 31a, which are glued over the adhesive areas, may be sewn together for reinforcement. The sewn areas are designated by the reference numeral 50. In addition, although not shown, the overlapping portions of the lower end 12q of the front sleeve cap portion 12, the lower end 32q of the front sleeve cap joined portion 32, the lower end 25q of the back inclined joined portion 25, and the lower end 35q of the back inclined joined portion 35, which are the bases of the underarm joining portion 36a, may also be sewn together to reinforce the adhesion.

[0039] -When the round collar part 40 is one piece (Figure 21, Figure 22)- When the round collar part 40 is a single piece, the fabric for the round collar is cut into a C shape and adhesive is applied along the outer edge. On the back surface of the round collar part 40, one end 40a is left uncoated, and the other end 40b is coated with adhesive from the outer edge to the inner edge.

[0040] Next, the central portion of the round collar part 40 to which adhesive has been applied in this manner is overlapped with the areas to be adhered of the front collar cutout 11a of the front body 10, the shoulder and sleeve parts 30, and the side collar cutout 31a of the shoulder part 31, as shown in Figure 21, and temporarily secured in several places. One end 40a and the other end 40b of the round collar part 40 protrude outward from the side collar cutout 31a of the shoulder part 31. Thereafter, the other end 40b of the round collar part 40 is pulled toward the one end 40a, and the ends 40a and 40b are temporarily fastened together. Next, as shown in Figure 22, the back collar cutout portion 21a of the back body 20 is overlapped and temporarily fixed onto the adhesive application area R of the round collar part 40. The subsequent steps are as shown in Figure 14 and subsequent figures.

[0041] - Shirt A without round collar part 40 - A normal shirt A has a round collar part 40 attached, but the round collar part 40 may be omitted to create a simpler shirt A. In this case, as shown in Figure 6, after both shoulder and sleeve parts 30 are attached to the front body 10, the back body 20 is attached to both shoulder and sleeve parts 30, and finally the front edge lower part 16 of the front body 10, the back edge lower part 26 of the back body 20, and the underarm joining part 36a of the shoulder and sleeve parts 30 are attached. [Industrial Applicability]

[0042] Conventional shirts have armholes, and the sleeves are attached to these armholes in a three-dimensional structure, making it impossible to assemble them using a flat press. However, the shirt structure of this invention eliminates the armholes, making it possible to bond the entire adhesive application area by applying heat and pressure using a flat press, making it possible to produce shirts more cheaply and in larger quantities than before.
