  In addition, in each said figure, in order to make description easy to understand, the thickness of the front fabric and the back fabric was disregarded, and it described with the continuous line. In addition, the thickness and size of each member, the enlargement / reduction ratio, and the like are shown without matching the actual ones.

  The down jacket 1 according to the present embodiment includes a jacket body 31 and sleeves 32 sewn on the jacket body 31. The jacket body 31 includes a left front body 33, a right front body 34, and a rear body (not shown). Each piece of the jacket main body 31 and each sleeve piece of the sleeve 32 are the front fabric 11 that becomes the front side when worn by the user, the batting layer 50 including the down, and the back side (the user's body side) when worn by the user. It is formed by cutting a three-layer structure made of the backing fabric 21 into a predetermined shape and joining the pieces together.

  The jacket body 31 includes a plurality of stitched portions 10 formed by stitching the front fabric 11 and the back fabric 21 in the lateral direction (a direction perpendicular to the height direction of the user when worn by the user). Is formed.

  The stitching portion 10 is formed with a first seam allowance 13 between a first stitch 12 that stitches a region in which the front fabric 11 is folded and stacked, and a folded mountain 100 that is formed by the mountain folding. ing. In addition, the stitching portion 10 has a second seam allowance 23 between a second stitch 22 that stitches a region where the backing fabric 21 is folded and stacked, and a folded mountain 110 formed by the mountain folding. Is formed. The first stitch 12 and the second stitch 22 are formed in parallel to the folding mountains 100 and 110.

  Further, in the stitching portion 10, the first seam allowance 13 and the second seam allowance 23 are overlapped with each other, and the overlapped portions 100 and 110 are more folded than the first stitch 12 and the second stitch 22. Both sides are stitched together by a third stitch 43. At this time, the first stitch 12 and the second stitch 22 are almost overlapped on the same line. The front fabric 11 and the back fabric 21 are folded at the positions of the first stitch 12 and the second stitch 22 so that the first seam allowance 13 and the second seam allowance 23 are located inside.

  A space S defined by the stitched portion 10 and the stitched portion 10 adjacent to the stitched portion 10 is formed between the front fabric 11 and the back fabric 21 that are overlapped with each other. Filling layer 50 is filled. That is, the stitching portion 10 plays a role similar to that of a quilting portion applied to a normal down jacket (suppresses down movement and holds it in place).

  As shown in FIGS. 2 and 3 in particular, the stitching portion 10 has a direction in which the stitches of the first stitch 12 (the direction in which the sewing needle is inserted) is the direction in which the space S is arranged, and the front fabric 11 and the surface of the back fabric 21 are not exposed to the sewing needle holes. Therefore, the down or the like constituting the batting layer 50 does not come out from the sewing needle hole formed by the first stitch 12 to the surface of the front fabric 11 and the back fabric 21. Similarly, the direction of the stitches of the second stitch 22 is also the direction in which the space S is arranged, and the sewing needle holes are not exposed on the surface of the front fabric 11 and the surface of the back fabric 21. The down or the like does not come out from the sewing needle hole formed by the second stitch 22 to the surface of the front fabric 11 and the back fabric 21. Furthermore, since the sewing needle holes formed by the third stitch 43 are not exposed on the surface of the front fabric 11 and the surface of the back fabric 21, the down or the like comes out on the surfaces of the front fabric 11 and the back fabric 21. There is nothing. From the above, it is possible to reliably prevent the down or the like from slipping out to the surface of the front fabric 11 and the back fabric 21.

  Next, a method for sewing the stitching portion 10 of the down jacket 1 according to the present embodiment will be described.

  First, as shown in FIG. 4, a mountain fold line A for folding the front fabric 11 is set at a desired position of the front fabric 11. In addition, in FIG. 4, the line shown with the code | symbol B on the both sides of the mountain fold line A is a garment line. These two ground sewing lines B have substantially the same distance from the mountain fold line A.

  Next, as shown in FIG. 5, the mountain fold line A is used as the fold mountain 100, and the front fabric 11 is folded and overlapped, and the top lining line B that is a predetermined distance from the fold mountain 100 is sutured. A first stitch 12 is formed. By this step, a first seam allowance 13 is formed between the fold mountain 100 of the front fabric 11 and the first stitch 12. Further, the same process as that for the outer fabric is performed for the back fabric 21, and a second seam allowance 23 is formed between the fold mountain 110 of the back fabric 21 and the second stitch 22.

  Next, as shown in FIG. 6, the front fabric 11 and the back fabric 21 obtained in the step shown in FIG. 5 are aligned with the folds 100 and 110, and the first seam allowance 13 and the second seam allowance 23 are overlapped. The third stitch 43 is formed by sewing together the folds 100 and 110 with respect to the first stitch 12 and the second stitch 22. In this way, the stitched portion 10 is formed.

  Next, as shown in FIG. 7, the front fabric 11 is folded so that the first stitch 12 becomes a valley line, and the back fabric 21 is folded so that the second stitch 22 becomes a valley line. As shown, the first seam allowance 13 and the second seam allowance 23 are positioned inside the space formed by the front fabric 11 and the back fabric 21.

  Next, as shown in FIGS. 8 and 9, the desired number of stitched portions 10 are formed by repeating the steps shown in FIGS. 4 to 7 for the front fabric 11 and the back fabric 21 folded in the step shown in FIG. 7. To do. In addition, what is necessary is just to determine arbitrarily the distance of the stitching | suture part 10 and the stitching | suture part 10 adjacent to this stitching part 10 by the design, function, etc. of the down jacket 1.

A three-layer structure 21 (see FIGS. 2 and 3) is formed.

  In the present embodiment, the case where the first stitch 12 is formed in parallel to the fold mountain 100 of the front fabric 11 has been described. However, the present invention is not limited to this, and the first stitch 12 is not limited to the design of the down jacket 1 or the like. Depending on the function or the like, it may not necessarily be formed parallel to the folded mountain 100, such as being formed obliquely. The same applies to the second stitch 22.

  In the present embodiment, when the first seam allowance 13 and the second seam allowance 23 are overlapped, the first stitch 12 and the second stitch 22 are positioned on the same line. First, the first stitch 12 and the second stitch 22 do not necessarily have to be located on the same line.

  In this embodiment, the down jacket is described as an example of the sewing product. However, the present invention is not limited to this. For example, down vests, down pants, duvets, scarves, gloves, socks and other small items, plush toys, etc. It is not particularly limited as long as it is a sewn product in which a capillary fiber body having a capillary fiber on its surface is interposed, such as feather, feather, chemical fiber cotton or the like.

  Further, the front fabric and the back fabric used in the present invention are not particularly limited, but when the front fabric and / or the back fabric is a woven fabric, the gap formed by the warp and the weft is small, and the gap It is preferable to use a fabric from which the capillary fiber is not removed. Further, when the front fabric and / or the back fabric is a knitted fabric, it is preferable to use a knitted fabric having a small stitch and from which the capillary fiber body is not removed.

  The present invention provides a sewing product and a sewing method that can surely prevent the capillary fibrous body interposed between the front and back fabrics from slipping out of the surface of the front and back fabrics from the sewing needle holes. it can.
