BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel fabric sewing method for preventing seam slippage.

0002

BACKGROUND OF THE INVENTION In recent years, fabrics for clothing have been preferred to have a soft texture. In order to give a fabric a soft texture, effective methods include making the threads that make up the fabric thinner, making the weave density coarser, reducing the number of tissue points in the woven structure, and applying weight reduction processing. However, in fabrics processed by this method, the threads that make up the fabric tend to move, and when tension is applied to the seam, the base thread of the seam moves and opens (this phenomenon is called seam slippage). ), impairing the appearance of the seam and reducing its windproof and waterproof functions. Furthermore, in severe cases, the sutured portion may break, rendering the suture useless. Such problems often occur with georgette fabrics that have been subjected to weight reduction processing and satin fabrics with few tissue points, but with conventional sewing methods, such as ground stitching indicated by JIS-B-9003, number 325, the seam slips. Although the fold-down stitch indicated by number 336 and the fold-down stitch indicated by number 337 slightly reduce the seam slippage, the effect of preventing the seam slippage is small and cannot be said to have a practical effect.

[0003] As described above, conventional suturing methods cannot prevent seams from slipping off, so the above-mentioned soft-textured fabrics, which tend to slip off at seams, cannot be used as sewn products. Woven texture (twill weave,
In order to prevent the seams from slipping, fabrics with a soft texture had to be made to have a hard texture against their will, such as by making them plain weave (plain weave, etc.).

SUMMARY OF THE INVENTION An object of the present invention is to provide a fabric sewing method that prevents seams from slipping off.

[0005]

[Means for Solving the Problems] The present invention provides a method for sewing two pieces of fabric by folding back the edge of only the upper fabric of the two pieces of fabric overlapped at the seam part to the outside. After sewing the folded part together with the lower fabric (3 pieces),
Fabric suturing characterized by folding the other end of the lower fabric to the outside of the seam side and sewing together (4 pieces) the overlapped part of the folded part of the upper fabric and the folded part of the lower fabric. It's a method.

The present invention will be explained with reference to the drawings. FIG. 1 is a perspective view showing an example of the suturing method of the present invention in progress. In FIG. 1, 1 and 2 are two pieces of fabric to be sewn together, which are overlapped along the seam part (middle front), and the upper fabric 1 is folded back to the outside at the fabric edge line 4, and the lower fabric is folded at the seam 5. 2 and 3 pieces are sutured together. At this time, fold line 4 of the upper fabric
The distance between the seam line 5 and the seam line 5 is in the range of 1 to 6 mm, especially 2 to 4 m.
It is preferably within the range of m. When the interval is less than 1 mm, the effect of preventing seam slipping is great, but sewing is difficult and troubles such as the seam 5 coming off from the folding line 4 tend to occur.On the other hand, when the interval exceeds 6 mm, the effect of preventing seam slipping is small.

FIG. 2 is a perspective view illustrating an example of the suturing method of the present invention, showing a seam structure obtained by the method. In the sewing method of the present invention, the two pieces of fabric sewn together at the seam line 5 are then sewn together at the seam line so that the lower fabric 2 of the two pieces of fabric has the other end 10 of the fabric apart from the seam side. 5, and the overlapping part of the folded part 7 of the upper fabric and the folded part 9 of the lower fabric forms a seam line 8 and is integrated (
4 pieces) are sutured. In the seam structure obtained by the present invention, the distance between the seam line 8 and the seam line 5 (same as the folding line of the lower fabric) is preferably in the range of 1 to 6 mm, particularly 2 to 6 mm, for the same reason as above. Preferably, it is in the range of 4 mm. Here, seam lines 8 and 5 are lines passing through the center of the threads forming each seam.

[0008] Other dimensions are not particularly limited, but to give a preferred example, the distance between the cloth edge line 3 of the upper fabric and the folding line 4 of the upper fabric shown in FIG. 2, and the distance between the folding line 4 of the upper fabric and the bottom The distance between the cloth edge lines 6 of the side fabrics should be the same size from the viewpoint of workability when aligning and overlapping the cloth edges, and it is preferable that the interval be 8 to 12 mm, which is the same as the general seam allowance.

In the present invention, lock stitches and chain stitches can be used as the seams, and multiple stitches such as double stitches can also be used. The seam density is preferably low in order to prevent seams from slipping off, but is not particularly limited.

EXAMPLES The present invention will now be explained in more detail with reference to Examples. Example 1 Two pieces of satin fabric obtained by a conventional method (warp: polyester woolly 50 denier/24 filaments, weft: polyester filament 70 denier/36 filaments,
A sewn product having the seam structure shown in FIG. 2 was prepared using a woven structure of 8-ply satin, warp density of 45 threads/cm, and weft thread density of 41 threads/cm. For details on the seam structure, see the seam format;
Lockstitch, number of stitches: 5 stitches/cm, sewing thread: polyester filament #50, sewing machine needle: #11, the dimensions of each part shown in Figure 2 are the distance between the fabric edge line 3 of the upper fabric and the folding line 4 of the upper fabric ( (hereinafter referred to as 3-4); 10 mm, 4-6; 1
They were 0 mm, 5-4; 4 mm, and 5-8; 3 mm. Next, regarding the obtained sewn product, JIS-L-1096-6,
Seam slippage of the warp threads was measured by the 21,1B method (stitch slippage method, load: 5 kgf). As a result, seam slippage was 0.
It was 5 mm.

Comparative Examples 1 to 3 The same two pieces of satin fabric as used in Example 1 were sewn using method J.
Ground stitch specified by IS-L-1096-6, 21, 1B (stitch type: lockstitch, number of stitches: 5 stitches/cm, sewing thread: polyester filament #50, sewing machine needle: #11, seam allowance: 10 mm) (comparative example) 1), JIS-B-9003, down stitch shown in number 336 (stitch type: lockstitch, number of stitches: 5 stitches/cm, sewing thread: polyester filament #50, sewing machine needle: #11, seam allowance: 10 mm, stitch spacing ;7mm) (Comparative Example 2), JIS-B-9003,
Fold-down stitch indicated by number 337 (stitch type: lockstitch, number of stitches: 5 stitches/cm, sewing thread: polyester filament #50, sewing machine needle: #11, seam allowance: 12 mm,
Stitching was performed with a stitch interval of 7 mm (comparative example 3). Seam slippage was measured for each of the obtained sewn products in the same manner as in Example 1. The results are 5.6mm (Comparative Example 1), 3.8m
m (Comparative Example 2) and 3.0 mm (Comparative Example 3).

As shown in the measurement results of seam slippage, products sewn using the conventional suturing method (Comparative Examples 1 to 3) have large seam slippage, which is a problem for sewn products. Since the seam slippage is extremely small, there is no problem at all as a sewn product.

[0013]

According to the present invention, the effect of preventing seam slippage can be obtained. Seam slippage is a phenomenon in which when tension is applied to the seam, especially tension in the direction perpendicular to the seam line, the ground thread of the fabric moves toward the seam allowance (stitch slippage), and a hole is created in the seam by the amount of movement. Even if the stitch density is increased, this phenomenon has almost no effect, similar to untangling hair with a comb. However, when there is a folded part on the seam allowance side, the folded part prevents the seam from slipping off, just as a comb stops when untangling hair. Since the seam allowance in the seam structure formed according to the present invention is provided with a folded portion on both sides, the seam can be prevented from slipping off at the folded line.

Furthermore, by reducing the distance from the seam line on which tension is applied to the folding line that prevents seam slippage, the range in which the ground thread can move can be further reduced, and seam slippage can be prevented to an extremely low level. Can be done.

[0015] Since the present invention has such an effect, it can be effectively applied to sports clothing, work clothing, high-fitting clothing, bags for storing heavy objects, etc., in which strong tension is applied to the seams.
