[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a connection structure for a suture used to connect ends of a suture such as a woven fabric, a non-woven fabric, and a knit, and a suture connected by this structure.

[0002]

[Prior art]

 When a manufacturing process of a sewn product such as a woven fabric or a non-woven fabric has been conventionally completed, the ends of these sewn products are connected to each other, and the process proceeds to a subsequent process such as a dyeing process or a washing process. Here, as a conventional method for connecting end portions of a sutured article, as shown in FIG. 3, one end edge 50a of one sutured article 50 and the other end edge 51a of the other sutured article 51 are linear. A so-called straight stitch is performed with the thread 52 so as to form a single stitch 53. Then, as shown in FIG. 4, the one sutured article 50 and the other sutured article 51 connected to each other by this method are spread out as one piece of fabric 53, and the next step such as a dyeing step or a washing step. Will be migrated to. However, when connecting the one suture 50 and the other suture 51 by the above-mentioned method, the connected one suture 53 is squeezed by sandwiching the two sutures 53 by two rotary drive rollers (not shown), When the cleaning liquid, the dyeing liquid, etc. are removed by the work, the thickness of only the connecting portion becomes three times as thick as the thickness of the suture 53, and the two rotary drive rollers are often damaged. Therefore, in order to solve these problems, as shown in FIG. 5 or 6, respectively, one suture material 60, 70 and the other suture material 61, 71 are connected by threads 62, 72 so that they are flush with each other. A structure in which the fabrics 63, 73 are made into one sheet by rubbing can be considered. The connection structure of the sewn product shown in FIG. 5 has a thread 62 having a portion sewn from the vicinity of one end edge 60a of one sewn product 60 to the vicinity of the other end rim of the other sewn product 61. The structure for connecting the sewn object 60 and the other sewn object 61. The connection structure for the sewn object shown in FIG. 6 is sewn from one end edge 70a side of one sewn object 70 to the other sewn object 71 side. This is a structure in which the one sutured article 70 and the other sutured article 71 are connected by a thread 72 having a different portion.

[0003]

[Problems to be solved by the device]

 According to the method for connecting sutures shown in FIG. 5 or FIG. 6 described above, there is no portion where one suture 60, 70 and the other suture 61, 71 overlap each other, and the one suture 60, 70 and the other suture 60, 70 Since it is flush with the sutures 61 and 71, the rotary drive rollers are not damaged when the fabrics 63 and 73 are squeezed by being sandwiched by the rotary drive rollers as described above. However, in the suture connecting structure shown in FIG. 5, the thread 62 having a portion sewn from the vicinity of one end edge 60a of one suture 60 to the vicinity of the other end edge of the other suture 61 is provided. The length is extremely short, and the distance from the portion penetrated from one side to the other side of the fabric 63 to one end edge or the other end edge of the one suture 60 or the other suture 61 is extremely short. If the other sutures 60 and 61 are roughly woven, such as gauze, or depending on the material of the threads that make up the suture, it is possible that a predetermined tension is applied to the fabric 63 during the washing process or the like. In some cases, one suture 60 or the other suture 61 may be frayed from one end edge or the other end edge, and a stable connected state may not be maintained. On the other hand, in the connection structure of the suture object shown in FIG. 6 described above, the distance from the portion penetrated from one surface to the other surface of the fabric 73 to one end edge or the other end edge of the one suture object 70 or the other suture object 71. Since it is longer than the method of connecting the sutures shown in FIG. 5, the above-mentioned fraying is unlikely to occur, but as shown in FIG. The other end side of the sutured article 71 may be curved due to various processes.

Therefore, the present invention has been proposed in order to solve the problems of the above-described conventional connection structure for a suture, and is applicable to a connected stitch during various steps such as a washing step. A stable connected state can be maintained even when a predetermined tension is applied, and one end edge or the other end edge of one and the other sutures is not curved. The purpose is to provide a suture used.
