Description

[Detailed description of the invention] [Industrial application field] The invention relates to a thread for binding the outer material and lining of sewn products. The present invention relates to a yarn used to fasten an outer fabric and a lining fabric near a hem or the like, and the yarn is used as a knitting yarn.

[Conventional technology] Conventionally, when sewing the outer material and lining of a sewn product,
The entire area near the hem of these sewn products is sewn directly, and as described in Publication of Utility Model Publication No. 57-40251, the hem is sewn through another cloth.
Fixed using a straight line of thread, or
As shown in Figure 5, a method is used in which one end of a straight thread is sewn into a part of the outer fabric, a part of it is knitted, and finally it is sewn into a part of the lining to secure it. Ta.

When using a single straight sewing thread N as a knitting thread during sewing work as described above, when forming the first loop L and after passing the sewing needle through the loop to prevent the last loop L from slipping off, The part where the last loop L is pulled and becomes a straight sewing thread without forming a knitting thread, that is, the straight part 16,1
7 is formed. In this case, although it is more durable than the case where the outer fabric H and the lining U are simply fastened together using one straight sewing thread, it has the disadvantage that the linear parts 16 and 17 are easy to cut, and the sewing process is difficult. Sometimes, when loops are sequentially formed in the middle of the sewing thread attached to the sewing needle to form the knitted part 15, and when passing the sewing thread through the last loop L, the sewing needle may prick the finger, which is a major drawback in terms of safety. was.

[Problems with the prior art] Among the above-mentioned prior art, there are two methods: one in which the outer material and the lining are sewn together directly, and one in which the entire surface is sewn through another cloth as described in Publication of Utility Model Publication No. 57-40251. In some cases, the outer fabric and lining of the resulting sewn product, such as a suit jacket or skirt, are pulled together and have diagonal wrinkles due to sewing, that is, "hanging".
If these wrinkles appear while the sewing product is new, it is possible to immediately re-sew the product, but
When a sewn product is new, "hanging" is difficult to appear, and it often appears after it has been worn several times, that is, after the tension of the outer material has decreased, causing trouble with customers.

On the other hand, if the outer fabric and the lining are not completely sewn together as described above, and the outer fabric and the lining are fixed in several places with a distance of 5 to 6 cm using a single straight sewing thread, the tensile force is small. It also has the disadvantage of being easily cut due to unresistance.

Fig. 5 is a partial vertical cross-sectional view of a conventional product in which the outer material and the lining are sewn with one sewing thread.The sewing shown in Fig. 5 involves passing one straight sewing thread N through a sewing needle. With a knot 11 formed at one end of the loop L, a loop L is formed on the outer material H, and the sewing thread N on the sewing needle side is threaded through the previous loop in the middle and knitted one after another so that a new loop is formed. The knitted part 15 is formed, and when the knitted part 15 reaches a certain length, the sewing needle is sewn into the lining U and passed through the loop L to prevent the loop L from coming off, and then the needle is sewn into the lining U again. Sew it in. Then, a sewing thread N knot 12 is formed and cut. 13 and 14 are cut portions near the knots 11 and 12.

[Means and effects for solving the problem] An object of the present invention is to cut the knitting yarn after sewing the outer fabric and the lining used to obtain a sewn product that eliminates the drawbacks of the conventional sewn products. To provide a knitting yarn for binding the outer material and lining of a sewn product, in which the cut portion does not spread apart even after the cut portion is formed.

The structure of the present invention is that the knitting yarn for binding the outer material and lining of the sewn product is knitted using three yarns consisting of yarn 1, yarn 2, and yarn 3, and the Thread 1 and Thread 2 are thick yarns, Thread 3 is 40% to 60% thicker than Thread 1 or Thread 2, (A) Thread 2 and Thread 2 are thick. Thread 3 is doubled to form a doubled yarn, and the vicinity of the knitted yarn of yarn 1 is inserted into the loop made of the doubled yarn to form a loop, and with the loop of yarn 1 inserted, the yarn is doubled. (B) Insert the braided portion of the doubled yarn into the loop of the yarn 1 to form a loop, and with the loop of the doubled yarn inserted, tighten the loop of yarn 1; A knitting yarn for binding the outer fabric and lining fabric of a sewn product, characterized in that it is knitted by sequentially repeating the above (A) and (B).

The present invention will be explained in detail using drawings.

1 and 2 are schematic diagrams of the knitting yarn for binding the outer material and lining of the sewn product according to the present invention, FIG. 1 is a front view, and FIG. 2 shows the knitting yarn of FIG. 1 in the vertical direction. to
It is a back view rotated by 180 degrees.

3 and 4 show a sewn product using the knitting yarn according to the present invention, FIG. 3 is a schematic longitudinal cross-sectional view of FIG. 4, and FIG. 4 is a front view of the sewn product. .

The knitting yarn according to the present invention is knitted by yarn 1, yarn 2, and yarn 3 as shown in FIGS. 1 and 2. Yarn 1 and Yarn 2 are thick yarn counts, and Yarn 3 is a fine yarn count. and yarn 2
and yarn 3 are doubled.

The knitting of yarn 1, yarn 2, and yarn 3 is performed by inserting the yarn into the loop 1Y formed by yarn 1 and forming the new yarn 2 and yarn 3 into the unknitted portions 2Z and 3Z. As a result, a loop is formed, and in a state where the loop of yarn 2 and yarn 3 is formed, the unknitted portion 1Z of yarn 1
By pulling, the loop 1Y of yarn 1 is made smaller, and then the unknitted portion 1Z of yarn 1 is inserted into the loop formed by yarn 2 and yarn 3 to form a new loop. is formed, and with the loop of yarn 1 formed, the loop of yarn 2 and yarn 3 is made smaller by pulling the portions of yarn 2 and yarn 3 that have not yet been knitted.

That is, yarn 1, yarn 2, and yarn 3 are knitted by repeating the above operations.

The knitting yarn according to the present invention is knitted as described above, and the yarn 1 is 1A, 1B, 1C, 1D.
...In order, yarn 2 is 2A, 2B, 2C, 2D, 2
In the order of E, 2F..., yarn 3 is 3A, 3B, 3C,
They are organized in the order of 3D, 3E, 3F...
As thread 1, thread 2, and thread 3, it is preferable to use commonly used threads. In the case of sewing thread, it is twisted, and each thread is independent as a thread, so that loops can be easily formed and threads can be inserted into the loops without cutting single threads during knitting.

Thread 1 and Thread 2 are of thick count, and Thread 3 is of thin count. However, Thread 2 of thick count and Thread 3 of fine count are doubled together and knitted with Thread 1. The knitting yarn knitted by this method has excellent binding properties and is strongly knitted, and has the effect that the thread does not come off and the cut portion is difficult to unravel when used in sewn products.

The thickness of the yarn 3 is 40% to 60% of the thickness of the yarn 1 or the yarn 2.
Thread 3 is 20% thicker than Thread 1 or Thread 2.
%, the effect of using yarn 3, that is, there is almost no difference from the knitting yarn knitted using only yarn 1 and yarn 2, and by making it above, the binding property is improved. It becomes noticeable. On the other hand, if yarn 3 exceeds 80% of yarn 1 or yarn 2, the binding property will be low, and the combined yarn of yarn 2 and yarn 3 will be
The yarn is extremely thick compared to the yarn 1, and only the yarn 1 protrudes outward, substantially creating unevenness, making it difficult for the knitting yarn to be smoothly bonded to the outer lining during sewing. These improvements in binding properties and sewing workability become remarkable when the thickness of yarn 3 is 60% or less of that of yarn 1 or yarn 2.

Here, yarn 1 and yarn 2 are created without using yarn 3.
If the knitting yarn is knitted with chisel, the binding properties of each of yarn 1 and yarn 2 that form the knitting yarn will be reduced, and the knitting will not be strong, resulting in a cut part when used for sewn products. The fabric tends to be unraveled into pieces, and when sewing begins, the cut part is nautical and it is necessary to cut and remove the unraveled part. In the end, it may be necessary to use parts that are not organized.

It is preferable to use threads 1 and 2 having a thickness of 40 to 90, respectively, and they may have the same thickness, or either one may be thicker. In the case where either of the yarns is made thicker, it is desirable that the thickness of the yarn 2 be in the range of 70% to 120% of the thickness of the yarn 1. If the thickness of thread 1 and thread 2 is thinner than 90 thread count, the entire knitting thread becomes thin and may come off from the outer material or lining depending on the sewn product, and the strength will also decrease. On the other hand, if it is thicker than 40, the sewn portion may become uneven when the outer material and the lining are sewn together, making the sewn portion visible from the outside, which is not desirable as a product.

If the thickness of yarn 2 is made thinner than 70% of yarn 1, the thickness of yarn 2 and yarn 3 will become close to each other, and the binding properties of the entire knitting yarn may decrease. Furthermore, if the thickness of yarn 2 to yarn 1 exceeds 120%, the knitted yarn will have a shape in which yarn 1 protrudes outside of yarn 2 and yarn 3, and Thread 2 Thread 3
The binding performance with the yarn 1 may decrease, and the strength contribution rate of the yarn 1 may decrease.
Furthermore, the releasability of the cut may be increased.

When the knitting yarn according to the present invention is used for a sewn product 4, for example, a skirt shown in FIG. is sewn with knitting thread K according to the present invention.

6a is the outer material H1, H of the sewn product 4 in FIG.
7a is the seam allowance due to seaming of 2, and 7a is the outer material H
This is the sewing thread that sewed together 1 and H2. 6b shows the seam allowance of the lining U, and 7b shows the sewing thread of the lining. 8
is the joint part between the outer material H and the knitting yarn K, and the joint part 8
is sewn by passing the knitting thread K through the sewing needle so that it does not appear on the surface of the outer material H. Either of the connecting portions 8 and 9 may be formed first. The length between the joining parts 8 and 9 of the knitting yarn K, that is, the free length, can be selected depending on the type of sewing product and the types of fabrics for the outer material H and lining U, and in the case of a suit jacket, it is 5 to 7 cm. is preferable, and in the case of a skirt, 4 to 8 cm is preferable.

When the outer fabric H and the lining U of a sewn product are bonded using the knitting yarn according to the present invention, the entire area from the bonding portion 8 to the bonding portion 9 is knitted, and the knitted yarn 1 and yarn 2 are knitted. and the excellent binding properties of the yarn 3 ensure the connection between the outer material H and the lining U,
In addition to increasing durability, since it is a knitting yarn, it does not twist in one direction unlike twisted yarn, and it is possible to beautifully finish sewn products without damaging the outer material H and lining material U.

In addition, since it is a knitting yarn, even if forces are applied to the outer material H and the lining material U from different directions, the elastic properties of the knitting thread can absorb the force and buffer the force applied to the outer material and the lining material. can.

Further, when sewing the outer material and the lining material, there is no need to form a loop in the thread and insert the thread for knitting, thereby improving safety without causing finger pricks caused by sewing needles.

[Effects of the invention] The knitting yarn according to the invention has excellent binding properties of the knitted yarn, and has elasticity and strength. When combined, the knitting yarn does not have a thick portion and a thin portion, so it is homogeneous and difficult to cut, improving durability, and the sewn product can be of high quality without wrinkles.

Furthermore, by using the knitting yarn of the invention, there is no need to form loops in the thread while knitting the thread during sewing, which improves safety by eliminating the risk of finger stings caused by sewing needles. It has many effects.
