Description

Non Overlapping Sewing Method and the Cloth of the same}

The present invention relates to a non-overlapping (NOL) sewing method in which two or more fabrics do not generate waves, have good tension, and do not require seam allowance.

In general, when you want to put both fabrics together after cutting the fabric, you sew one piece of cloth on the other, usually sewing one cloth on top of another and sewing it on top of another. The method of sewing was used.

1a to 1e shows a sewing method according to the prior art.

As shown in FIG. 1A, first, another second cloth 2 is placed on the first cloth 1, and the seam is sewn on the part to be sewn to make a seam allowance line (4) to form a seam allowance (3).

Then, cut off only part of the seam allowance 3 (FIG. 1B). Then, the other second cloth 2 is unfolded on the opposite side of the first cloth 1 around the seam allowance line (FIG. 1C).

Then, by sewing the coupling portion of the two fabrics (1, 2) around the seam allowance to combine the two fabrics (Fig. 1d).

1A to 1D, the cross section of the sewing part is sewn together by sewing three cloths as shown in FIG. 1E, so that the sewing part is thickened by this method.

In addition, there is a problem in that the case of sewing the fabrics sewn as described above again, that is, in the case of the portion where the four fabrics are combined, there may be a case where the overlapping of the fabric six times.

Therefore, the present invention is to solve the above problems, the object of the present invention when sewing the cloth after sewing, the sewing is sewn so that the fabric is not overlapped in the sewing portion does not cause the skin bleeding and less pressure when worn The present invention provides a method of sewing a fabric that can feel comfortable and a fabric produced by the method.

Non-overlapping sewing method according to the present invention that can achieve the above object, the first step to overlap the first cloth and the second fabric to be sewn with the first cloth; A second step of cutting and pasting the overlapped first and second fabrics using an ultra sonic welding apparatus to form a first assembly; And a third step of sewing the joined portion of the first assembly; It relates to a non-overlapping sewing method comprising a.

And the sewing method of the third step can be sewn by the Guy Rupa method. In addition, it is preferable that the first and second cloths are provided as a knitted material such as a lightweight woven jacket or a lining-free wind woven material or a material for t-shirts, swimwear, tights, and underwear.

And after the third step, a fourth step of overlapping the third cloth and the fourth cloth to be sewn with the third cloth; A fifth step of cutting and pasting the overlapped third and fourth fabrics using an ultra sonic welding apparatus to form a second assembly; A sixth step of sewing the joined portion of the second conjugate; A seventh step of overlapping the first assembly and the second assembly to be sewn together; An eighth step of cutting and bonding the overlapped first and second binders using an ultra sonic welding apparatus to form a third binder; And a ninth step of sewing the joined portion of the third conjugate; It is possible to be sewn, including.

And the fabric produced by the above method can be provided.

According to the present invention, there is an advantage in that the sewing portion is not thickened because the sewing is not made by overlapping the cloth and the cloth, but sewing the cloth and the cloth side by side.

In addition, it is not necessary to form a seam allowance because it is not necessary to form a margin during sewing. And since a thick sewing portion does not occur, the wear phenomenon is less on the skin when wearing such a cloth can reduce the discomfort to the wearer.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows a flow chart of a non-overlapping sewing method according to an embodiment of the present invention, Figures 3a to 3e is a view showing a non-overlapping sewing method according to an embodiment of the present invention.

As shown in the drawings, first, the two cloths to be sewn, that is, the first cloth 110 and the first cloth 110 and the second cloth 120 to be aligned so as to overlap each other.

At this time, the alignment may not be accurate. This is because when the overlapped first cloth 110 and the second cloth 120 are cut using the ultra sonic welding device, the cut portions are exactly matched. The ultra sonic welding device may be an ultra sonic lace machine (HTM-6770) manufactured by Nawon Machinery Co., Ltd. (www.nawon.com).

The use of the ultra sonic welding device not only cuts the first cloth 110 and the second cloth 120 but also joins the first cloth 110 and the second cloth 120 to each other. In this way, the bonded fabric is called the first assembly 100 for convenience.

The first assembly 100 shares one side of the first cloth 110 and the second cloth 120 with each other and is attached to the first cloth based on the coupling part 140 with the second cloth 120 placed thereon. Spread to the other side of the 110 is a sewing operation is made for the coupling portion 140.

In this case, when the second cloth 120 is unfolded to the opposite side of the first cloth 110, the whole of the cloth is based on the coupling part 140 instead of being unfolded as the second cloth 120 overlaps as shown in FIG. 1E. The shape of the cross section of the first assembly 100 is thus almost completely flat as in FIG. 3E.

Thus, the sewing is made to the coupling part 140 (150).

In this way, even if sewing is made, a non-overlapping sewing method of the cloth, in which the sewing portion is not thickened as in the prior art, becomes possible.

The above sewing method may be based on the Guy Rupa method. The gairupa method is a method of sewing a cloth, and means a method of sewing each other in a loop form that is connected like a staircase, which is obvious for those skilled in the art.

The fabric produced by the manufacturing method as described above, the bonding portion 140 and the sewing portion 150, which is a portion where the cloth is attached to each other is not relatively thicker than the thickness of the cloth, even if the cloth directly touches the skin, the skin of the skin is relatively There is little and can feel comfort. Therefore, the cloth is preferably a knitted material such as a lightweight woven jacket or a lining-free wind woven material, and also has a less irritating effect on the skin when used on t-shirts, swimwear, tights and underwear that can be worn directly on the skin. have. Woven material here refers to the fabric of the material consisting of weft and warp.

Figure 4 shows a flow chart of a non-overlapping sewing method according to another embodiment of the present invention, Figure 5a to 5d is a view showing a non-overlapping sewing method according to another embodiment of the present invention.

The method of sewing the third cloth 230 and the fourth cloth 240 with each other is the same as that described in FIGS. 2 to 3E and is made by combining the third cloth 230 and the fourth cloth 240. This is called the second assembly 202 for convenience. In addition, what is made by combining the first cloth 210 and the second cloth 220 is called a first assembly 201 for convenience.

That is, in the method of sewing the third cloth 230 and the fourth cloth 240 to each other, firstly, the third cloth 230 and the third cloth 230 and the fourth cloth 240 to be sewn overlap each other. The overlapped third cloth 230 and the fourth cloth 240 are cut and bonded using an ultra sonic welding apparatus to make a second binder 202 and sewing the bonded portion of the second binder 202. By doing so.

As shown in the drawings of FIGS. 5A to 5D, first, the two fabrics to be sewn, that is, the first assembly 201 and the first assembly 201, and the second assembly 202 to be sewn are arranged to overlap each other.

At this time, the alignment may not be accurate. This is because when the overlapped first and second assemblies 201 and 202 are cut using an ultra sonic welding device, the cut portions are exactly matched. The ultra sonic welding device not only cuts the first assembly 201 and the second assembly 202 but also joins the first assembly 201 and the second assembly 202 to each other. In this way, the bonded fabric is called the third assembly 203 for convenience.

The third assembly 203 is configured to bond one side of the first assembly 201 and the second assembly 202 to each other, and to attach the second assembly 202 placed thereon to the first assembly based on the coupling portion 260. Unfolding to the opposite side of the 201 is a sewing operation is made to the combined portion.

At this time, when the second assembly 202 is unfolded to the opposite side of the first assembly 201, the second assembly 202 is not expanded while overlapping as shown in FIG. The entirety of 202 is spread out on the opposite side. As a result, the shape of the cross section of the third assembly 203 is almost completely flat as in FIG. 3E.

Thus, the sewing is made to the coupling portion 260 (270).

In this way, even if sewing is made, a non-overlapping sewing method is possible in which the sewing portion is not thickened as in the prior art.

The above sewing method may be based on the Guy Rupa method. The gairupa method is a method of sewing the cloth, which means a method of sewing the fabrics together in a loop form connected like a staircase, which is obvious for those skilled in the art.

Even when three or more fabrics are combined as described above, the fabric made by the manufacturing method according to another embodiment of the present invention has a thickness of the fabric that is relatively the thickness of the joining portion 260 and the sewing portion 270 where the fabrics stick to each other. Even if the cloth does not become thicker and the fabric comes into direct contact with the skin, the skin is less swept and can feel comfortable.

Therefore, the cloth is preferably a knitted material such as a lightweight woven jacket or a lining-free wind woven material, and also has a less irritating effect on the skin when used on t-shirts, swimwear, tights and underwear that can be worn directly on the skin. have.

The present invention has been described with reference to preferred embodiments of the present invention, but the present invention is not limited to these embodiments, and the claims and detailed description of the present invention together with the embodiments in which the above embodiments are simply combined with existing known technologies. In the present invention, it can be seen that the technology that can be modified and used by those skilled in the art are naturally included in the technical scope of the present invention.
