Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a seam reinforcing tape used for reinforcing a sewn portion and obtaining dimensional stability when sewing clothes.

[0002]

[Prior art]

 Conventional seam reinforcement tapes, which are used to sew the edges of two part cloths together when sewing clothes or other cloth products, are usually thinner than the part cloth and have one side of cloth of an appropriate structure. A heat-adhesive tape obtained by cutting a raw cloth having a heat-adhesive layer on its entire surface to a width of 10 to 15 mm is generally used.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional seam reinforcing tape is formed by laminating and bonding a heat-adhesive layer on one side of the cloth along the seam allowance of one part cloth of the cloth to be sewn and then laminating the other part cloth. The sewing allowances are overlapped and sewn on the sewing machine. For example, at the sewn edge of the body part cloth and the facing part cloth of the garment, seam reinforcing tape is laminated on the back side of the seam part cloth in advance and heat-bonded by ironing, and then the body part cloth Lay the facing part cloth on the front side, pass the seam reinforcing tape through the parts, and sew both parts cloth on the sewing machine, then turn both parts cloth over in the opposite directions and position the seam allowance part between the two cloths. The sewing thread line is used as the edge, and a stable shaped edge is obtained by ironing.

In addition, the body part cloth to which the two outer material part cloths are sewn in a plane, and the seam part cloth, the sleeve part cloth, the back collar part cloth, etc. In the heat-sealed seam reinforcing tape part, both parts cloth are sewn together, and the seam allowance of both cloths is divided and ironed on the back side to obtain a stable seam.

In the above stitching means, since the seam reinforcing tape is heat-bonded to almost the entire surface of one seam allowance, a seam-reinforcing and stretch-preventing sewn portion can be obtained. The texture is hardened by the adhesion, and the thickness of one part cloth edge part where the seam reinforcing tape part is folded is further increased, and when the iron part is applied to stabilize the sewn part. However, there is a defect that it may cause damage to the appearance of clothes.

[0006]

[Means for solving the application]

 The present invention solves the above-mentioned problems in the conventional seam reinforcing tape in which one side is entirely heat-bonded. That is, the present invention is a thin wide bias tape having repulsion and a thin narrow width of one third or less of the width of the wide bias tape overlapped and stitched along one side edge of the wide bias tape. The tape has a narrow width, and the narrow tape has a heat-adhesive layer distributed and adhered on the outer surface thereof, and is characterized by a seam reinforcing tape for sewing.

In the above description, the repulsive thin wide width bias tape is obtained by bias cutting a thin woven fabric using a relatively rigid thin yarn into a width of usually 15 to 30 mm. As the woven fabric, for example, a plain woven fabric having a cloth thickness of 50 μ or less with a synthetic mono or multifilament yarn of 25 de or less and a warp / weft density of 50 yarns / 25 mm or less is preferably used. The narrow tape is made of a woven cloth, a non-woven cloth, or other thin cloth of any desired structure, on one side of which a thermal adhesive layer made of thermoplastic synthetic resin such as polyamide, polyester, or polyethylene is distributed and adhered. It is cut to a width of 3 to 6 mm, which is one third or less of the width of the wide width bias tape. The width of the narrow tape is the same as or slightly thicker than that of the wide bias tape, and the heat-adhesive layer distributed and adhered to one side of the tape is usually 4 to 10 g / square meter of fine particles of the heat-adhesive. Those that are distributed and attached so as to have a density are preferable.

In the reinforcing tape of the present invention, one side along one side edge of the wide width bias tape is contact-polymerized with a surface of the narrow width tape on which the thermal adhesive layer is not provided, and is usually a single-line sewing machine sewing machine. It is obtained by joining both tapes by gluing. With the above structure, the flexible wide width bias tape is reinforced by the narrow width tape that is sewn on one side edge of the flexible wide bias tape to provide easy-to-handle shape retention. It is about half or less than the heat-bonding seam reinforcing tape.

[0009]

[Action]

 The seam-reinforcing tape of the present invention can be used in the following manner according to the sewing conditions for two part cloths, so that a soft and stable seam can be obtained together with seam reinforcement. Hereinafter, a case will be described as a typical example in which the sewn portions of the outer material cloth, the facing material cloth, and the lining material material form the edges of the garment. 1st step: On the back side of the seam allowance of the outer material part cloth, the seam allowance cloth edge and the narrow width tape edge of the seam reinforcing tape are made to substantially coincide with each other or an appropriate space is provided from the outer material part cloth edge to make a wide bias tape. Are laminated so that they are located beyond the seam allowance, and the thermal adhesive layer surface of the narrow tape is adhered to the seam allowance surface of the outer material part cloth by ironing.

Second step; a wide bias tape which is placed on the surface of the outer material part cloth so that the facing material cloth or the lining material cloth is overlapped with each other so that the seam allowances of both cloths coincide with each other, and is close to the narrow width tape of the seam reinforcing tape. Sewing the sewing machine through the surface. 3rd step: Along the sewing line of the sewing machine, the wide bias tape part of the outer material part cloth and the seam reinforcing tape is turned over to one side, and the facing part cloth is turned over to the other side. Do

According to the above-mentioned sewing means, the narrow tape of the seam reinforcing tape is located in the seam allowance of both parts cloth, and the folded wide bias tape is overlapped beyond the narrow tape. It is held between both parts cloth, so that the surface side of the sewn edge avoids the hand-hardening due to the adhesion of the narrow tape, and during the intermediate ironing, the narrow tape part has a wide repulsive width. By superposing the bias tape, it is possible to prevent the occurrence of contact with the ground surface, and to obtain the effect of shaping the ground surface. The above-mentioned sewing method is suitable for sewing body part cloth and collar, front facing part cloth, or part cloth such as cuff hem and hem hem and lining part cloth, and especially the outer cloth has a transparent portion such as lace. In this case, the folded portion of the wide bias tape is on the lower surface of the outer cloth of the sewn portion, and the presence of the seam reinforcing tape portion is obscured to obtain a good appearance.

[0012] In the above-mentioned sewing means, the seam reinforcing tape has the overlapping portion of the narrow tape sewn on one side edge thereof, which is bonded to the sewing seam allowance. When a non-adhesive interlining such as a hair core is provided, a narrow tape of the seam reinforcing tape is attached to the edge of the interlining, and the wide bias tape portion is extended on the outer seam allowance, The narrow tape portion may be sewn on the outer material. In this case, the narrow tape portion is located on the interlining surface, and the folded portion of the wide bias tape is a sewn edge that is overlapped. It is possible to omit the step of sewn sewn stitches, and it is possible to obtain the same shaping, shape-retaining effect, and iron hitting prevention effect as described above.
