Abstract

PURPOSE:A plurality of sheets are arranged so that small gaps are left between adjacent sheets and they are sewed by threading across the interface to give sheets suitable for use as summer clothing, because of its high breathability. CONSTITUTION:A plurality of sheets in the form of bands or rectangles, for example, sheets of waste artificial leather after removing defect parts, are arranged in parallel so that small gaps are left between adjacent sheets 1, 1 and they are sewed by threading across the gap 4, e.g., they are sewed in zigzag where the needle thread 2a and the bobbin thread 2b are connected by round binding and at least 3 knots per 1 stroke are formed to prevent these threads from untying. The small openings 4 between sheets gives the resulting sheet breathability and the sheet can be suitably used as summer clothing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sheet formed by joining sheet pieces with thread.

[Background Art] Artificial leather has been introduced as a substitute for natural leather, but as the manufacturing technology of artificial leather has improved, there has been a desire for higher quality leather. The current situation is that as the desire for luxury products increases, the manufacturing process becomes more complex, and as a result, the probability of producing defective products increases. The defective fabrics that occur in this way are ranked according to the degree of defectiveness, and those with a low degree of defectiveness will have their prices reduced, while those with a high degree of defectiveness will be discarded. This also reduces the manufacturing cost of artificial leather, and there is a desire to recycle defective fabrics with high commercial value. This is true not only for artificial leather but also for textiles, nonwovens, resin sheets, etc.

Therefore, in order to regenerate the above-mentioned artificial leather in terms of its commercial value, the present inventors, for example, sewed together rectangular or band-shaped sheet pieces obtained from fabrics of artificial leather to create one piece from a large number of artificial leather sheet pieces. We considered regenerating artificial leather seats.

However, in this case, it has been found that various problems arise when the sheet pieces are sewn using conventional sewing methods.

That is, as one of the conventional sewing methods, the one shown in FIG. 6(a) is one in which the ends of the sheet pieces 1, 1 are overlapped on one side, and this overlapped part is sewn together with thread 2. In the case shown in FIG. 6(b), the ends of the sheet pieces 1.1 are overlapped vertically and the overlapped parts are sewn together with thread 2. However, in these cases, an overlap allowance is required for sewing, resulting in a loss of dimensions for the overlap allowance, which poses a problem in terms of cost.Also, this overlap allowance increases the thickness at the sewn part. It becomes stiff and feels bad to the touch, and in addition, since the sheet pieces are sewn together with the same overlap, the sheet pieces 1°1 are stuck together at the sewn part, and there is no breathability in this area (especially with artificial leather, it is difficult to breathe). (If there is no air permeability in the sewn part, the body will get stuffy, making it unsuitable for clothing.) As a result, the sheet obtained by sewing the sheet pieces 1 together cannot be used for clothing, especially summer clothing. There is a problem that the usage is limited. Furthermore, especially in the case shown in FIG. 6(a), the overlapping allowance protrudes from the sheet piece 1, so the overlapping allowance can only be provided on the back side of the sheet, and the sheet must be used only on the front and back sides. There is also the problem of it disappearing.

[Object of the Invention] The present invention has been made in view of the above points, and it is possible to sew the sheet pieces without loss, and has excellent feel and breathability, making it suitable for summer clothing. The object of the present invention is to provide a sheet that is not limited in its use and is not limited in its front and back sides.

[Disclosure of the Invention] The sheet according to the present invention has a plurality of sheet pieces 1.1.
... are arranged so as to face each other with a gap 4 between the end faces of adjacent sheet pieces 1, 1, and each adjacent sheet piece 1, 1 straddles between the end faces of sheet pieces 1, 1. The above object is achieved by arranging and sewing the sheet pieces 1 in this way. Explain in detail.

As the sheet piece 1, in addition to those obtained from the defectiveness of the artificial leather described above, those obtained from natural leather, woven fabric, nonwoven fabric, resin sheet, etc. can be used, and in some cases, those obtained from artificial leather of good quality. You can also use

In short, any sheet-like material that can be sewn with thread can be used. The sheet piece 1 is usually formed into a band shape, and first, a case where the sheet piece 1 is a band shape will be explained.

FIG. 1 shows an embodiment of the present invention, in which a large number of strip-shaped (tape-shaped) sheet pieces 1, 1, . . . are arranged in parallel with a gap 4 between adjacent sheet pieces 1, 1. Each adjacent sheet piece 1, 1 is sewn by a thread 2 spanning between its ends. Here, to illustrate the dimensions of the sheet piece 1 and the gap 4, the width dimension of the sheet piece 1 is 1.5 mm, and the width dimension of the gap 4 is 0.51 mm. The thread 2 is sewn, for example, in a zigzag stitch by a zigzag stitch sewing machine, and when sewing with a zigzag sewing machine, the thread 2 is composed of two threads, an upper thread 2a and a lower thread 2b, and the upper thread 2
a is from one side of sheet piece 1, bobbin thread 2b is from one side of sheet piece 1
will be sewn into the sheet piece 1 from the other side, but at this time, the upper thread 2a and the lower thread 2b will be sewn into the round knot 3.
It is so that they are tied together. That is, as shown in FIG. 5(,), part A of upper thread 2a that is fed downward by the previous step of the needle of the sewing machine is caught on part B of upper thread 2b that is fed from the bobbin, and The upper thread 2a and the lower thread 2b are respectively supplied so that the C portion of the upper thread 2a, which is pulled upward by the reversing process of the sewing machine needle, is further hooked on the downward D portion of the lower thread 2b, and the sewing machine When the sheet piece 1 is fed by the feeding mechanism, a tensile force is applied to the upper thread 2a and the lower thread 2b, so that the hooked part of the upper thread 2a is absorbed.
and the bobbin thread 2b are tied with a round knot 3 as shown in Figure 5 (1). And Figure 4 (,
), the knots 3 are made in three places per 10-stack S of the zigzag stitch. In the embodiment of FIG. 4, one of the three knots 3 is made in the sheet piece 1 and the other two are made in the gap 4 between the sheets 1, 1; It is also possible to have two in the gap 4, one in the gap 4, etc. In this way, when sewing the sheet piece 1.1 with the upper thread 2a and lower thread 2b using a sewing machine, the upper thread 2a and the lower thread 2b are connected by the knot 3, so that the sheet can be sewn together. Even if the upper thread 2a and lower thread 2b are cut due to cutting or washing, the fraying of the upper thread 2a and lower thread 2b will stop at the knot 3 and the fraying will not progress any further. This prevents the sheet pieces 1 from coming unstitched and coming apart due to fraying of the upper thread 2a and lower thread 2b. Here, if the knot 3 is provided in one stroke S, :E, as in the case shown in FIG. The effect can be obtained even if the number of 3 locations is less than this. It should be noted that the threads 2 (upper thread 2a, lower thread 2b) are stronger than the sheet piece 1, such as Tetoron thread coated with a petroleum-based reinforcing resin to increase its strength by about 2.5 times. If this is done, even if the sheet piece 1 is torn, the sewing thread will not break and a strong sheet can be obtained, and the thread 2 can be formed into a thin piece for use.

A large number of sheet pieces 1°1 obtained as described above...
The sheet with ・ sewn is formed by arranging the sheet pieces 1.1..., so by forming each sheet piece 1 in a different color, it is possible to create sheets with various color patterns. The sheet piece 1 can be finished and the raw material from which the sheet piece 1 was obtained can be sold as a product, but it also has various other excellent features. That is, since the gaps 4 are interposed between the ends of each adjacent sheet piece 1, this gap 4 can provide a large amount of breathability, making it possible to make the sheet suitable for summer clothing. Ru.

The thread 2 used to sew the sheet pieces 1 and 1 is the sheet piece 1.1.
The gap 4 between the garments has a mesh-like appearance, making it suitable for summer clothing. Of course, in addition to summer clothes, it can also be used as a covering material for hakamako, etc. In this case, the mesh can provide the coolness of a formal dress. In addition, since the gaps 4 are interposed between the ends of each adjacent sheet piece 1 in this way, an overlap allowance is not required when sewing the sheet pieces 1, and a loss due to the overlap allowance does not occur. There is no
Rather, sheet piece 1. The sheet piece 1 is separated by the gap 4 in [1].
This means that it is possible to obtain a sheet with a larger area than the total area of . In addition, since there is no overlap, the thickness of the sewn part does not increase due to overlapping of the overlap, and the flexibility of the sheet piece 1 is maintained without becoming stiff in this area. be able to. Furthermore, since there is no overlapping allowance and the sheet pieces 1 are butted together as described above, it is possible to prevent the sewn portions from distinguishing between the front and back of the sheet. In this case, if the front and back sides of the sheet piece 1 are formed with different colors or patterns, the sheet F can be used on both sides with different color patterns. Since the sheet is formed by aggregation of sheet pieces 1, 1..., it is possible to obtain a sheet of any size by increasing or decreasing the number of sheet pieces 1. However, by increasing the number of sheet pieces 1 sewn in the width direction, the sheet can be made as wide as desired. be.

In the embodiment shown in the fjSi diagram, the strip-shaped sheet pieces 1 are arranged in the horizontal direction, but of course they may be arranged in the vertical direction. Each sheet piece 1 may be of the same color or may be of a different color to form a knitted pattern. Further, in the case of the embodiment of tAlrg, sheet pieces 1 of the same width were used, but sheet pieces 1 of different widths may be used in combination as shown in FIG. 2(a).

Furthermore, in each of the examples described in Section 2, all the sheet pieces 1.1...
In this case, a gap 4 was formed between adjacent sheet pieces 1, 1, but as shown in FIG. 2(b), some sheet pieces 1
, 1, the end surfaces may be butted against each other without leaving a gap between them.

In each of the above embodiments, a strip-shaped (tape-shaped) sheet piece 1 is used, but a rectangular sheet piece 1 can also be used. That is, as shown in FIG. 3(,), a large number of rectangular sheet pieces are arranged vertically and horizontally with gaps 4 in between, and adjacent sheet pieces 1.1 are sewn together with thread 2. In the embodiment shown in Fig. 3(,), sheets are made using sheet pieces 1 of various different sizes, or as shown in Fig. 3(b), sheets 1 of the same size and weight are used. They may be arranged vertically and horizontally with rows and columns aligned.

In this case, for example, if you color-code the sheet pieces 1, 1, etc. into two different colors and arrange the sheet pieces 1 so that the sheet pieces 1 of different colors are next to each other, you can create the sheet for Marquis Ichimatsu. can be finished. Furthermore, even if these sheet pieces 1 are formed into rectangular shapes, some of the sheet pieces 1.1
A gap 4 may be formed in the opening, and the end surfaces of the sheet pieces 1, 1 may be butted against each other without forming a gap between some of the other sheet pieces 1, 1. In addition, in each of the above embodiments, by using a colorful thread as the thread 2, the thread 2
This allows you to create a design with an accent. Further, the sheet piece 1 can be of any shape, such as the above-mentioned band shape or rectangle shape, triangular shape, hexagonal shape, or the like.

1. Effects of the Invention] As described above, in the present invention, a plurality of sheet pieces are arranged in a state where the end portions of adjacent sheet pieces are opposed to each other with a gap between them, and each adjacent sheet piece is connected to the sheet 1. Since the sheets are sewn together with a thread that spans between the ends of the sheets, there is a gap between the ends of each adjacent sheet piece, and this gap provides great ventilation, making it ideal for summer use. The sheet can be made into a sheet suitable for clothing, and the thread used to sew the sheet pieces has a mesh-like appearance in the gaps between the sheet pieces, making it suitable for summer clothing. It is a matter of fact. In addition, since there is a gap between the ends of each adjacent sheet piece in this way, there is no need for an overlap allowance when sewing the sheet pieces, and there is no loss due to the size of the overlap allowance. Rather, the gap between the sheet pieces makes it possible to obtain a sheet with a much larger area than the total area of the sheet pieces.
The cost can be reduced. Also, since there is no overlap, the thickness of the sewn part will not increase due to overlapping of the overlap, and the flexibility of the sheet piece can be maintained without becoming stiff in this area. Furthermore, since there is no overlapping allowance, it is possible to prevent the front and back of the sheet from being distinguished by the sewn portion, and the use of the sheet F can be widened.
