JPS6042310B2 - Machine embroidery method where the sewing thread does not appear on the back side of the embroidery fabric - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of machine embroidery in which cotton thread does not appear on the back side of embroidered cloth.

That is, in this invention, the cotton thread created by the so-called sachin stitch, which is the embroidery part where the embroidery thread crosses diagonally across the pattern structure of the embroidery pattern, does not appear on the back side, and the back side is smooth and smooth. This machine embroidery method saves embroidery thread because it can be tightened, and the tension on the surface is gentle, giving it a nice texture and a soft-feeling embroidery pattern.

Traditional embroidery using a sewing machine is desired to be as close to hand embroidery as possible technically and to be efficient. On the other hand, when using a sewing machine, a certain amount of tension is required for the embroidery upper thread and embroidery bobbin thread, so
The embroidered cloth may shrink or tear around the pattern, making it difficult to obtain a beautiful, well-textured embroidery pattern. Therefore, the present invention solves the above-mentioned disadvantages of conventional sewing machines, and also does not allow the cotton thread to appear on the back side, making the embroidery surface thin and smooth, which causes a feeling of discomfort when worn. We have developed a rational and resource-saving embroidery method.

Basically, when embroidering a desired pattern 2 on an embroidery cloth 1, this invention basically involves making the back side of the embroidery cloth face the upper surface, and embroidering the ring part 2 of the pattern 2 on the back side 3 of the embroidery cloth 1.
A first needle thread 5 for embroidery and a second needle thread cloth 6 for embroidery are placed on both sides (hereinafter referred to as "first needle thread 5, second needle thread 6").

” attached to the machine, and use the two needles installed on the sewing machine to
The upper thread 5 and the second upper thread 6 are passed through the embroidery cloth 1 alternately, and the embroidery lower thread 7 (hereinafter referred to as "lower thread 7") is caught and sewn to create a surface of the embroidery cloth 1. It is characterized in that a cotton thread 9 is exposed on the back side 3 by a so-called sachin stitch, and an embroidery pattern 10 is applied on the back side 3 without being exposed. Next, embodiments of the present invention will be described in detail based on a non-limiting embodiment of a sewing machine with reference to the drawings.

Figures 1 to 5 of the drawings are part 5 of the implementation instructions for the sewing machine (parts are omitted in Figures 2 to 5).
1 is the sewing machine body, 12' is the needle bar of the first needle 12, 13' is the needle bar of the second needle 13, 12'' and 13'' are the needle holes of each needle, 1
4 is a needle plate, 15 is a needle window, 16 is a hook, 17 is a bobbin thread bobbin,
18 is a feed dog device for feeding the embroidery cloth 1 to an appropriate position according to the pattern, 19 is a tension adjustment device, and 20 is a balance.

The first needle 12 is a needle to which the first needle thread 5 is attached, in which a hook 16 containing the bobbin thread 7 moves up and down every predetermined number of operations and pauses once. Further, the second needle 13 moves up and down while the first needle 12 is at rest, and attaches the second needle thread 6. Therefore,
The embroidery method of the present invention will be specifically described.

(See Fig. 1) Insert the first needle 12 into the embroidery cloth 1 facing the throat plate 14 (processed side) with the back side 3 facing upward (see Fig. 2), and thread the lower thread using the first upper thread 5. 7 and returns to the original position to sew 21 and rest (see FIG. 3). At the same time, the first upper thread 5 is moved to the hook 1 by the action of the thread take-up 20.
6 and is tightened together with the bobbin thread. Next, the embroidery cloth 1 is carried by the feed dog device 18 to a suitable position according to the embroidery pattern 2 to be obtained, and at that position the second needle 13 is inserted from the back side 3 of the embroidery cloth 1 ( (See FIG. 4), the lower thread 7 is caught by the second upper thread 6 and returned to the original position, thereby sewing 2' and stopping (see FIG. 5).

At the same time, the second upper thread 6 is moved to the hook 1 by the action of the thread take-up 20.
6 and is tightened together with the bobbin thread 7. The above movement is achieved at the limbal part of pattern 2, 4 (Figs. 6 to 9).
(see figure) alternately (sew 21, 2" above)
By continuously repeating the sewing, sewing 2 on the surface 8 is performed.
1 and 2 are embroidery patterns 10 and 2 in which satin stitches are used in between to expose the sewing thread 9 and the embroidery pattern 10 is applied on the reverse side without the embroidery thread being exposed.

A part of the example pattern 2 shown in FIG. 6 will be explained.

The parts where the bobbin thread 7 is sewn with the first needle 12 using the first needle thread 5 are indicated by A, C, E, G~, and the parts where the bobbin thread 7 is sewn with the second needle 13 with the 24th needle thread 6 are shown. are denoted by B, D, F~.

Since sewing and embroidery are performed using the method described above and the position of each embroidery thread, the tension of the first and second needle threads 5 and 6 is set to Y-Y in FIG. 6 with respect to the embroidery cloth 1. Acts in the axial direction, X-X
Since only the tension of the bobbin thread 7 is exerted in the axial direction, the embroidery pattern applied to the embroidery cloth surface 8 appears in a soft state, and is characterized by a good texture.

Also, since there is no embroidery thread 9 on the back side 3 and it is very smooth and smooth, the first and second embroidery cloths of the same color as the embroidery cloth 1 are
If upper threads 5 and 6 are used, it can be felt that there are almost no threads on the back surface 3. As mentioned above, the present invention provides an embroidery method that can create an embroidery pattern that is completely different from conventional sewing machines.
The explanation will be as follows with reference to FIGS. nine
When sewing with the upper thread 22 and the lower thread 23 In order to sequentially sew the A, opening, C, 2, H, H ~ portions of the pattern 25 on both the front and back sides of the embroidery cloth 24, the upper thread 22 and the lower thread 23 are The embroidery thread 27 by so-called satin stitch appears diagonally between the ring portions 26 on both sides on both the front and back surfaces 7, and the tension acts doubly.
Distortion or shrinkage of the pattern in the X-axis direction may occur, and the embroidery cloth 2
Furthermore, since the upper and lower threads 22 and 23 are sewn in the same amount on both the front and back sides, the embroidered portion of the embroidery cloth 24 becomes thick and lumpy. Therefore, it had the disadvantage of making people feel uncomfortable when wearing something using this material.

The present invention uses an extremely rational embroidery method that disperses the tension of the upper and lower threads, thereby reducing the tension on the embroidered cloth and improving the quality of the finished product.
In the end, it is possible to obtain an embroidered product that is closer to hand embroidery, and since the embroidery thread does not appear on the back side,
The embroidery surface becomes smooth and thin, so when you wear something made of this material, you will feel much less uncomfortable, and the embroidery thread will also be saved, so it can be produced and provided economically. It is.
