[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing method for preventing slippage of a sword rag in a shirt or the like.

[0002]

2. Description of the Related Art Conventionally, a slit formed on a sleeve for sewing a cuff, such as a shirt, blouson or blouse, covers a cut on both side edges of the slit and has an overlap on both side edges. Furthermore, a button is attached as a means for opening and closing the slit, and a cloth called a sword rag for forming a buttonhole is sewn.

As shown in FIGS. 4 and 5 (a), this sword rag is sewn to one side edge 53a on the right side of the slit in the drawing, and an upper cloth piece having a sword shape from which the name is derived. 51
And a lower cloth piece 52 sewn to another side edge 54a on the left side of the slit in the figure and smaller than the upper cloth piece 51.

At the time of sewing, first, the lower cloth 5
After the side edge 58a of the second back portion 58 is stitched 61 to the back side of the slit side edge 54a, the lower cloth piece 52 is turned back, and the folded front side portion 57 is overlaid on the back side portion 58, and the cut edge is cut. The folded side edge 57a and the slit side edge 54a are stitched 62 together. The same applies to the upper cloth piece 51. The side edge 56a of the back side portion 56 is changed to the slit side edge 53a.
Then, the upper cloth piece 51 is turned upside down, pulled out to the front side of the slit and overlapped on the lower cloth piece 52, and the folded front side portion 55 is superimposed on the back side portion 56, and cut off. 55a and slit side edge 53
a is sewn 64. Thereafter, the halved portion is stitched 65, and the upper and lower cloth pieces 5 are further cut at the slit base end.
The sewing is completed by sewing 66, 67 on the sleeve body 50 with 1, 52. Reference numeral 59 denotes a button.
The upper cloth piece 51 has a buttonhole (not shown).

The upper and lower cloth pieces 51, 52 of the sword rag thus sewn are slit side edges 53a, 5a as described above.
The main purpose is to cover the cut of 4a, and the seam allowance of both side edges 53a, 54a of the slit is sewn to the respective cloth pieces 51, 52 in a flat state without folding or the like. When a tensile force F acts on the slit side portions 53, 54, the slit side edges 53a, 54a
Thread 6 for sewing the upper and lower cloth pieces 51 and 52 of the sword rag
1, 62, 63, 64, the total tensile force F acts directly on the warp yarns 53y, 54y of the slit side edges 53a, 54a intersecting with the pulling direction, and the frictional force between the warp yarns 53y, 54y and the weft yarns. It will receive a tensile force F.

[0006] For this reason, a material having a low frictional force for integrating the weft and the warp of the fabric, that is, a material woven with a yarn having a small surface friction coefficient, or a simple pattern of intersection between the warp and the weft as in a plain weave. If the material, furthermore, a material with a weak threading or a flannel material, has insufficient sewing allowance, and when a tensile force F acts on both side portions 53, 54 of the sleeve body 50 at the time of changing clothes, the slit side edges 53a, 54a Warp thread 5
There is a problem that the ragged cloth pieces 51 and 52 slip off together with 3y and 54y.

In particular, the lower cloth piece 52 of the sword rag must be covered under the upper cloth piece 51, so that the width of the seam allowance 54a must be reduced, and the button 59 is sewn 68. Since the pulling force F acts intensively on the part where it is present, this part often slips off as shown in FIGS. 4 and 5 (b).

[0008]

SUMMARY OF THE INVENTION In view of the above-mentioned points of the conventional sword rag sewing, the present invention can completely prevent the sword rag from slipping off even with a material such as a material that is easily driven into a fabric thread. The purpose is to obtain a sewing method.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of a sword rag that implements the slippage prevention sewing method of the present invention. In the figure, the sword rag is sewn to the right edge 31a of the slit formed at the tip of the sleeve 3 and is sewn to the left edge 32a of the slit, and is located below the upper cloth 1. The front side portions 11 and 21 and the back side portions 12 and 22 are formed by folding one piece of cloth in two along a slit direction which is a longitudinal direction thereof. . Hereinafter, the sewing process will be described with reference to FIG.

First, as shown in FIG. 3 (a), the interlining 4 is adhered to the portion where the upper and lower cloth pieces 1 and 2 are sewn, that is, the surface of the sleeve body 3 where the slit is formed. Next, as shown in FIG. 3 (b), the upper cloth piece 1 formed in advance on the back surface of the sleeve body 3 to which the interlining 4 is adhered, and having the side edges 11a, 21a and the sword tip portion 13 folded back. After the surfaces of the lower cloth pieces 2 are aligned and the side edges 12a, 22a of the respective back portions 12, 22 are aligned with the slit forming line (33), the sewing is performed in order 41, 42, and then the slit forming is performed. A cut is made along the line (33) to form a slit 33.

At this time, at the end of the slit 33, Y
Cuts 34 are formed in the shape of a letter so that the ends of the cuts 34 reach the ends of the sutures 41 and 42.

Then, as shown in FIG. 3 (c), the lower cloth piece 2 of the sword rag is pulled out to the front side of the slit 33, and the left edge 32a of the slit 32 and the rear side edge of the lower cloth piece 2 are stitched. Split the seam allowance of 22a by ironing operation,
The front side portion 21 is superimposed on the seam allowance of the slit left side edge 32a obtained by dividing the seam allowance, and the side edge 21a and the slit left side portion 32 are stitched 43. Further, the triangular portion 35 between the above-mentioned Y-shaped cuts 34 is folded back to the front side.

Further, as shown in FIG. 3 (d), the upper cloth piece 1 of the sword rag is pulled out to the front side of the slit 33 and superimposed on the lower cloth piece 2, and the above-mentioned stitched right edge 31a of the slit 41 and the upper cloth piece. 1, the seam allowance of the back side portion side edge 12a is divided, the front side portion 11 is superimposed on the seam allowance of the slit right side edge 31a, and the side edge 11a and the slit right side portion 31 are overlapped.
Are stitched 44 as shown in FIG.

When the upper cloth piece 1, the lower cloth piece 2 and the sleeve body 3 are double-stitched 46 and 47 near the end of the slit 33, sewing of the sword is completed. In the stitching 47, the folded triangular portion 35 at the end of the slit is stitched together, and in the stitching 46, the portion immediately before the end of the slit 33 is stitched.

As described above, in the upper and lower cloth pieces 1 and 2 of the sewn sword rag, the slit side edges 31a and 32 of the sleeve body 3 are formed.
a, and the seam allowances of the back side edges 12a, 22a of the cloth pieces 1, 2 sewn thereto are folded back by the seam allowance, and therefore, the weft (FIG. 2 in the left-right direction) is folded in the same manner, and intersects the sewing threads 41 and 42 at the folding point, respectively.

For this reason, when a tensile force in the lateral direction as shown by F in FIG. 2 acts on both side portions 31 and 32 of the slit 33 to which such a sword rag is sewn, the tensile force F becomes the slit. Each of the wefts of the side edges 31a, 32a and the back side edges 12a, 22a of the cloth pieces 1, 2 is received by the weft thread itself, and the shear strength of the weft thread and the sewing threads 41, 42 is as follows.
It is much larger than the friction force that unifies the warp and weft of the fabric.

The upper and lower cloth pieces 1 and 2 of the sword rag are also sewn on the front side portions 11a and 21a.
Separately, sutures 43 and 44 are provided on both sides 31 and 32 of the slit.
Then, the tensile force F is shared between the sewn portions and the sewn portions 41 and 42, and the tensile force acting on each sewn portion is reduced accordingly.

Further, the cloth itself is reinforced by bonding the interlining 4 to the both side edges 31a and 32a of the slit, and stitches 41 and 42 are formed at the reinforced portions.

Therefore, in the sword rag according to the sewing method of the present invention, the tensile strength of the sword rag composed of the pair of upper and lower cloth pieces 1 and 2 is remarkably improved due to the synergistic action of the sword rag, and slippage thereof is completely prevented. In spite of such strength advantages, the time required for sewing and ironing operations at the time of sewing, the required skills, and the appearance are not much different from those of the conventional art. Except for the interlining 4, the upper and lower sewn portions have four layers (five layers in the past), and the seam allowance is reduced. The seam allowance does not become too thick.

Incidentally, the pair of upper and lower cloth pieces 1 and 2 may be constituted by one piece of cloth, and after the stitches 41 and 42, the slit 33 may be cut together with the sleeve body 3 when cutting the slit 33. In the above embodiment, the folded portion of the upper cloth piece 1 is
Although the case of performing is shown, it may be omitted depending on the type of the shirt. In the case of a material having a small tendency to slip off, the adhesive interlining 4 can be omitted.
Tensile strength is significantly improved compared to conventional sword rags,
A considerable slip-off prevention effect is obtained. Further, in the above-described embodiment, the case where the sewing method of the present invention is applied to both the upper and lower cloth pieces 1 and 2 has been described. However, the sewing margin at the side edge of the slit has to be relatively narrow, and the button 5 is not used. Even if the sewing method of the present invention is applied only to the lower cloth piece 2 in which the pulling force acts intensively on the sewn portion and the tendency of slippage is more remarkable at that portion, a considerable slippage prevention effect can be obtained. it can.

[0023]

As described above, in the sewing method for preventing the sword rag from slipping in the shirt or the like according to the present invention, the slits 33 formed on the sleeves are sewn to both side edges 31a and 32a, and one piece of cloth is attached to each piece. A sword which is composed of a pair of cloth pieces 1 and 2 on both sides comprising front side portions 11 and 21 and back side portions 12 and 22 folded in two along the slit direction and covering the cuts of the side edges 31a and 32a. In the rag sewing method, the sleeve body 3 of the slit forming portion is formed before the slit 33 is formed.
After the back side portions 12 and 22 of the ragged cloth pieces 1 and 2 are aligned with the back surface of the sword, and both sides of the slit forming line are sewn 41 and 42 so that the seam allowance along the forming line of the slit 33 remains.
A cut is made along the slit forming line to form a slit 3
3 is formed, and then the ragged cloth pieces 1 and 2 are slit 33.
Of the sword ragged cloth pieces 1 and 2 with the seams cut back, and the slit side edges 31 where the seam allowances are divided.
a, 32a, the side edge of the slit and the suture 4
3, 44, it is excellent in the strength against the tensile force acting in the direction in which the sewn portion is pulled away, and can prevent the sword rag from slipping off even with a material or a flannel material that is easily driven into a fabric thread.
In addition, since only four layers of fabric are required at the seam allowance, the seam allowance is reduced, which is advantageous for thick materials.

Furthermore, despite the above advantages, the labor and required skills of sewing are not much different from those of the prior art, and there is no need to sacrifice productivity and cost.

In the sewing method described above, before forming the slit 33, the interlining 4 is bonded in advance to the surfaces of the side edges 31a and 32a of the sleeve body 3 at the portion where the slit 33 is formed.
Sleeve body 3 and sword ragged cloth back side 1 together with the adhesive interlining 4
When the stitches 41 and 42 are stitched to each other, the tensile strength of the stitched portion is further improved, and in addition to completely preventing slippage of the sword rag, deformation of the fabric at the time of sewing is prevented. There is also an advantage that work such as sewing allowance can be easily and reliably performed.
