JP5382571B2 - Sewing fabric and method for producing the same - Google Patents

Description

  The present invention relates to a woven fabric such as clothing and bags by substantially no sewing, and a method for manufacturing the same.

Conventionally, the manufacturing method of clothing using woven fabric is woven by cutting the front and back, using the pattern of each part such as the collar and sleeves after weaving the woven fabric, and sewing the cut parts It was normal.
Further, in the history of Banshu weaving, which is the origin of the non-sewn fabric of the present invention, there were lapet weaving developed in Taisho 11th, swivel weaving developed in 1948, loop weaving developed in 1958. They were used as embroidery, but in particular, swivel weaving techniques are used.

  Up to now, a technique has been known in which a woven fabric is woven in two layers and only the portions in the shape of clothes are joined and woven (for example, see Patent Document 1).

JP 2001-115357 A

Originally, when manufacturing garment clothing, bags, or industrial filter products, it is necessary to manually cut the fabric and material along the pattern and sew the cut fabric and material manually. It was. For this reason, it becomes a complicated process, and mass production by machines is difficult, and even if you want to make custom-made garments such as clothes, you have to wake up the pattern from what was measured on an individual order and apply the pattern to cut it. There was a tendency to spend too much time and money.
Accordingly, there is an urgent need for non-sewing technology when manufacturing textile garments, bags, or industrial filter products.

  In the technique of Patent Document 1 described above, in a method for forming a fabric product from a woven fabric, weaving is performed with multiple structures using jacquard, and at least one first layer of the multiple structures is attached to at least one side surface of the fabric product. Weaving between the first layer and the second layer along the outline of the fabric product so that one second layer is the other side of the fabric product, leaving the joint except for the opening. By cutting the cloth, the cloth product in which the first layer and the second layer are connected by the connecting portion is cut out.

The structure of the connecting portion described in Patent Document 1 is a yarn with little entanglement between the warp and the weft so that the opening of the collar, sleeve, and hem can be easily exposed at the time of cutting. The collar, sleeves, and hem are frayed. For this reason, it has been necessary to increase the confounding property by giving an angle to the weft so that it is difficult to fray, or by driving every few (for example, every 8) processed yarns (weary nylon) as wefts. .
Moreover, in the structure of the connection part described in patent document 1, in order to maintain intensity | strength in a connection part, there exists a subject that a textile structure has a restriction | limiting.

  Therefore, an object of the present invention is to be able to join (that is, sew) without depending on multiple structures in the configuration of the connecting portion. And it aims at realization of the substantial non-sewing which sews with the process of weaving and is completed as clothes etc. only by cutting along the outline of the woven fabric.

  As a result of diligent research, the present inventors focused on the method of using the weft peculiar to the swivel weaving technique peculiar to the region, and weaved the weft together along the outline of the shape of the clothing in the process of weaving the fabric. succeeded in. By cutting the outer shape line so as not to cut the weft of the woven fabric, it is possible to realize non-sewing of the finished fabric such as clothing.

  Conventional swivel weaving has been a common sense that embroidery is performed while weaving at a fixed position. In the present invention, this concept of common sense is overturned, and the swivel weaving in the present invention is devised so that the shuttle moves in accordance with the position of the warp. In the swivel weave, since the above-described connecting portion is configured, unlike the above-described Patent Document 1, there is no restriction on the fabric structure for maintaining the strength in the connecting portion, and the weft structure is made of another weft. There is no such thing as a piece coming out when cutting the connecting part.

That is, in the method for producing a non-sewn fabric according to the present invention, a two-layer or multilayer first woven structure is woven, and at the same time, at least one or more wefts that do not form the first woven structure are formed while moving. the different second weave from said first weave being the the first weave suture, said second weave is configured using a woven Suwaiberu Suwaiberu yarn moves Rukoto It is characterized by.

In the above-described method for producing a non-sewn fabric, the weft forming the second woven structure does not pass through the entire width of the first woven structure.
In addition, the above-described method for manufacturing a non-sewn fabric is characterized in that the second woven structure is constituted by wefts that do not form a ground structure .
In the above-described method for producing a non-sewn woven fabric, the woven fabric is woven with a two-layer or multilayer first woven structure, and at least one layer of the first woven structure is formed on one side surface of the woven fabric and the other at least one layer. Is the other side surface of the woven fabric, and the connecting portion that non-separably connects the side surfaces along the outer contour of the woven fabric is configured by the second woven structure.

The non-sewn woven fabric of the present invention is a first woven fabric formed by moving a first woven structure having two or more layers and at least one or more wefts not forming the first woven structure. A second woven structure different from the structure, and the first woven structure is stitched by the second woven structure, and the second woven structure is configured using a swivel weaving in which a swivel yarn moves. It is characterized by.

Here, specifically, the weft forming the second woven structure does not pass through the entire width of the first woven structure. Specifically, the second woven structure is composed of wefts that do not form a ground structure . More specifically, the first and second layers are woven in a two-layer or multi-layer first woven structure, and at least one layer of the first woven structure is provided on one side of the woven fabric, and at least one other layer is provided on the other side of the woven fabric. A connecting portion that is a side surface and connects the side surfaces in a non-separable manner along the outer contour of the fabric is configured by the second woven structure.
These non-sewn fabrics are used as clothing, industrial filters and bags.

  According to the non-sewn woven fabric of the present invention, since it is a simple operation of inserting a special weft thread into the weaving machine, everything can be performed by a machine. For this reason, costs such as labor costs are suppressed, and the process of cutting and sewing each part is incorporated into the weaving process, which shortens the time.

  In addition, since the non-sewn woven fabric of the present invention does not use a pattern paper, clothing can be obtained simply by measuring and inputting data. For this reason, even if you want to make custom-made clothes, it can be offered at a low price.

Further, unlike a sewing machine that is sewed with two threads tangled, it is the same as hand-sewing that sews a kimono, so even people with weak skin will not rub at the seam.
Furthermore, there are no particular restrictions on the woven material, and all materials such as cotton, wool, acrylic, polyester, rayon, silk, etc. are applicable.

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

  As Example 1 of the present invention, a two-layer woven structure (first woven structure) is woven, and at the same time, at least one swivel yarn that does not form the first woven structure is formed while moving. A non-sewn fabric in which two layers of the first woven structure are sewn by a woven structure (second woven structure) different from the one woven structure will be described.

  FIG. 1 shows a state in which a swivel yarn moves and a special weft is woven into a two-layer woven structure to provide a connecting portion in the two-layer woven structure. Here, the swivel weaving performed by the swivel yarn moving is mechanically performed by a swivel weft insertion mechanism using a movable shuttle.

  This swivel woven structure becomes a connecting portion, and the two layers of the woven structure are joined at an arbitrary position, an arbitrary shape line, or a shape surface. Originally, the swivel weaving technique is preferably used for embroidery and the like, and can be constructed at an arbitrary position, arbitrary shape line or shape surface.

  In FIG. 1, the swivel woven portions are a woven structure A of A1 to A2 and a woven structure B of B1 to B2. The woven structures A and B serve as a connecting portion of the two layers of the woven structure C. Here, by cutting along the left line of the woven structure A and the right line of the woven structure B, a tubular woven fabric as shown in FIG. In this case, the woven structures A and B which are swivel woven parts are independent and independent of the two-layered woven structure C.

  3-5 is a figure for demonstrating how to thread | yarn the swivel woven part of FIG. Here, both FIG. 3 and FIG. 4 are viewed perpendicularly to the surface of the two-layered weave structure of FIG. 1, and the difference between FIG. 3 and FIG. 4 is that the viewpoint for viewing the swivel yarn is changed by 90 °. . The two layers of the weave structure shown in FIG. 3 and FIG. 4 are each composed of a weft 1 and a warp 2. In FIG. 3, the weft thread (the weft thread) of the swivel thread 3 passes through the warp thread A from the front to the back of the figure. FIG. 4 illustrates a state in which the swivel yarn 3 is woven as a weft yarn. FIG. 5 is an enlarged view of the state where the weft (weft) of the swivel yarn 3 is applied to the warp yarn A.

FIG. 6 shows how a female one-piece garment was made in the manner described above. Here, the outlines (21, 22, 23, 24) are connecting portions of the woven structure formed by the wefts (wefts) of the swivel yarn 3. Further, the collar portion 31, the sleeve portions (32, 33), and the skirt portion 34 are portions that are not the connecting portion of the woven structure formed by the weft (weft) of the swivel yarn 3, and the two layers of the woven structure are separated. As a result, an opening is formed.
In this way, there are a portion where a special swivel weft yarn is woven and a portion where it is not woven. The woven portion is a portion that should be sewn, and is joined because it is a non-sewn fabric. The unwoven parts are the collar, sleeve and hem.
In the state of FIG. 6, it has already been completed as a one-piece garment.

  FIG. 7 is an enlarged view of an example of a two-layer woven structure of Example 1 and a swivel woven structure serving as a connecting portion thereof. FIG. 7 (1) is the fabric surface, and FIG. 7 (2) is the fabric back surface.

  FIG. 8 shows a part of a sample of the non-sewn fabric of Example 1.

As a device that weaves swivel yarn into the fabric while weaving multilayer fabric while simultaneously moving at least one swivel yarn, which is a sewing thread, the shuttle that operates the swivel yarn operates at high speed in air or linearly. is there.
Here, the operation of the shuttle will be described with reference to FIG. As shown in FIG. 9, the swivel yarn shuttle 5 is entangled with the warp yarn of the upper layer fabric and the warp yarn of the lower layer fabric, but when inserting the yarn from the left side to the right side and when inserting the yarn from the right side to the left side, The shuttle 5 has a reciprocating motion in which the movement direction is opposite.

  The present invention is useful for clothes, bags, and industrial filters.
