DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiple woven fabric capable of expressing a design on the surface of a woven fabric using only weft yarns without being affected by the color of the warp yarns.

[0002]

2. Description of the Related Art Conventionally, a woven fabric is formed by weaving a warp and a weft, and the color tone is changed by increasing or decreasing the number of connection points where the warp exceeds the weft, so-called warp points. Even if the number of warp points is increased or decreased in this way, warp yarns appear on the surface of the woven fabric, so that the color of the woven fabric depends on the color of the warp yarns.

In order to solve the above problem, Japanese Patent Laid-Open No. 8-32
Japanese Patent No. 5893 describes a picture weave in which a warp is composed of two or three adjusting yarns, and one of the adjusting yarns is selected for each connection point and is passed over the weft to form a woven fabric. Have been.

[0004]

However, Japanese Patent Application Laid-open No.
Also in the woven fabric described in Japanese Patent No. 325893, one of the adjusting yarns always appears on the surface of the woven fabric at the joining point, so that the color of the woven fabric depends on the color of the adjusting yarn, that is, the warp yarn. is there.

[0005] The present invention has been made to solve the above problems, and it is an object of the present invention to make it possible to express a design on the surface of a woven fabric using only weft yarns regardless of the color of the warp yarns.

[0006]

According to a first aspect of the present invention, there is provided a multi-layer woven fabric for solving the above-mentioned problems, in which an original picture such as a picture is decomposed into a large number of dots. a plurality of different colors of weft 2a, by determining the tissue pattern composed of a combination of 2b · · ·, with the fabric body representable said original on at least one surface is formed in the fabric body, the surface representing the original <br/> plurality of weft yarns 2a, only 2b · · · are arranged, and the plurality of weft
2a, 2b ... Up and down with respect to the surface representing the original picture of the fabric body
The warp 1 overlap in the direction is characterized by comprising coated multiply.

As described above, since the texture pattern composed of a combination of a plurality of different colors of wefts 2a, 2b... Is defined for the dots, the dots are diversified by the combination of the colors of the wefts 2a, 2b. And further in the fabric body,
Only a plurality of wefts 2a, 2b ... are arranged on the surface representing the original image
The surface representing the original picture of the woven fabric is warp

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a multi-layer fabric according to an embodiment of the present invention. FIG.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partially omitted cross-sectional view showing an embodiment of a multiple woven fabric according to the present invention. Hereinafter, a set of dots in a row in a horizontal direction, that is, a direction substantially perpendicular to a warp will be described as an example.

Here, one dot corresponds to each of the warp 1 and the weft.
2a and 2b, that is, a junction point where the two cross each other, that is, a region A in FIG.

In FIG. 1, 1 indicates a warp, and 2a and 2b indicate two wefts of different colors. As the weft, for example, ama-yarn is used. The two wefts 2a and 2b are positioned substantially at right angles to the warp 1, and with respect to the horizontal dot set in FIG. 1), the weft 2b is disposed below the warp (that is, on the back side) with respect to the third warp 1 from the left and the second warp 1 from the right in FIG. Is repeated in the direction of the warp yarn (weaving direction) to form the woven fabric main body 5.

Next, the principle of the arrangement of the two wefts in the vertical direction will be described. First, the weft 2b is arranged on the warp 1. At this time, when there is a dot arranged below the warp 1 (as shown in FIG. 1), the weft 2b is
I am nervous because I am hung on and pulled. After the weft 2b is arranged, if the weft 2a is more relaxed than the weft 2b and is arranged on the warp 1, the higher degree of tension of the yarn is always arranged below the weaker, so that the weft 2b is the weft 2a. It is arranged below.

As a result, the weft 2a is arranged on the weft 2b, the weft is "multiple", and the woven fabric is also "multiple".

Reference numeral 3 denotes a warp provided on the wefts 2a, 2b at predetermined intervals to hold the wefts 2a, 2b.
Thereby, the fabric main body 5 is pressed to form a desired multiple fabric.

The multi-layer fabric constructed as described above is formed by the following steps. First, an original image such as a painting or a photograph to be woven is read by a scanner, digitized, and the data is input to a computer. In a computer, input data is subjected to image processing to obtain a desired resolution, and then the original image is decomposed into dots at the resolution, and the color and saturation of each dot are stored in a memory. Less than,
One dot will be described. Further, a case where the color of the dot is orange will be described as an example.

From the colors of the dots stored in the memory, that is, the orange color and its saturation, the weft of the color necessary to express orange and the saturation of orange are analyzed by a computer. Is stored in the memory. For example,
If it is orange, you need red and yellow wefts,
Among the orange colors, the color is stored in the memory as a tissue pattern set in advance by a color such as a reddish orange color or a yellowish orange color.

Here, the texture pattern in the specification of the present application means a pattern of data that instructs a weaving machine how to draw a weft yarn with respect to a warp for one dot. At this time, the degree of weft pulling for one dot depends on whether or not the weft is arranged below the warp positioned on both sides of the dot.

The data relating to one dot stored in the memory as described above, that is, the color and texture pattern of the weft, are input to the weft selecting device and the loom, and the wefts 2a and 2b are passed through the warp as shown in FIG. The dots are represented by a woven fabric by combining the weft yarns 2a and 2b up and down.

By repeating the above operation for each dot, a combination of a plurality of wefts according to the texture pattern is connected, and the fabric body 5 is formed. The surface of the woven fabric main body 5 is pressed in a lattice shape by a warp yarn 3 having a diameter smaller than that of the warp yarn, and a multiplex woven fabric expressing a desired original image is formed.

In this embodiment, since the linseed yarn is used as the weft yarn, the color of the weft yarn 2b can be seen from between the single yarns of the weft yarn 2a.

As another embodiment of the multi-woven fabric according to the present invention, as shown in FIG. 2, four wefts 2a, 2b, 2c, 2d are used, and the vertical relationship of the wefts is more complicated than that of FIG. Is conceivable. FIG. 2 is a cross-sectional view showing a set of dots arranged in a row in a direction substantially perpendicular to the warp, similarly to FIG.

In FIG. 2, the warps are referred to as warps 1a, 1b, 1c, 1d and 1e in order from the left in FIG. Here, the dots formed by the warp yarns 1a and 1e are represented by the color of the weft yarn 2a, and the dots formed by the warp yarns 1b and 1d are represented by the mixed color of the weft yarns 2b and 2c based on the color of the weft yarn 2a. Are formed by the colors of the weft yarns 2c and 2d.

First, since the dots formed by the warp yarns 1a and 1e need only the weft yarn 2a, the weft yarn 2a is arranged above the warp yarn 1a and the other weft yarns 2b, 2c and 2d are arranged below the warp yarn 1a. A tissue pattern is applied to be placed.

Next, the dots formed by the warps 1b and 1d include:
The texture pattern is applied so that the weft 2a is arranged at the top, that is, the surface (the side on which the design is formed) of the woven fabric body 5, and the wefts 2b, 2c are arranged from the surface in this order.

The dots formed by the warp 1c are mixed with the color of the weft 2c and the color of the weft 2d.
The tissue pattern is applied such that d is placed from the surface in this order.

By arranging the design pattern applied in this way to the warp 1a to 1e, it is determined which weft is arranged under which warp. That is, in these texture patterns, the pulling condition cannot be determined by only one dot, and the pulling condition (up-down relationship of the weft) is finally determined by a series of dots in one row in the horizontal direction. .

As described above, since the wefts can be combined by vertically arranging the respective wefts, various colors can be expressed with a small number of wefts. Moreover, it is possible to express as if a plurality of wefts are twisted.

As another embodiment of the multiple woven fabric according to the present invention, it is possible to form a multiple woven fabric having a pattern whose one surface is different from that of the other.

As shown in the sectional view of FIG. 3, such a multi-layer fabric is prepared by first preparing, for example, two warps 1 and knitting each of the warps 1 with a weft group 2 formed by a plurality of wefts. Then, the weft group 2 is locked by the warp yarn 3 to form the cover. That is, each of the warps 1 and 1 is a weft group 2 so that the warp 1 is invisible from both surfaces of the respective fabric bodies 5 and 5 ′.
It is covered with. In each of the woven fabric bodies 5, 5 ', weft yarns are formed on one surface so that the original picture is represented.

Next, the first fabric main body 5 and the second fabric main body 5 'are put together in a state where the other surfaces thereof are inside (that is, the outside is a surface showing a design). The first fabric body 5 and the second fabric body 5 'are connected to the connecting yarn 6 (the warp 6a and the weft 6b different from those constituting the first and second fabric bodies).
To form a reversible multi-layer fabric having originals on both surfaces.

As described above, since the warp does not appear on the surface of the woven fabric body, it is possible to simultaneously weave two woven fabric bodies using two warp yarns and form the two woven fabric bodies into one woven fabric. it can.

Also, one dot is represented by a plurality of weft colors.
In addition, since the wefts are arranged vertically and combined, it is possible to express an original image such as a watermark.

In the above-described embodiment, the number of wefts is two or four. However, if the number of wefts is plural, the number can be changed as appropriate.

Further, in the above-described embodiment, the lower weft can be seen from the gap between the upper wefts by using the linseed yarn as the weft, but the weft is not limited to this. However, by using the amaori thread, the color expression can be made more versatile.

The multiple woven fabric according to the present invention is particularly preferably used for originals such as photographs, paintings, posters and the like which require detailed expressions.

[0038]

According to the present invention, it can be colorfully represented by the color combination of the plurality of dots weft, further textile
In the main body, only multiple wefts are on the surface representing the original image
Is arranged , the fabric main body is not affected by the color of the warp, and the original image can be expressed on the surface of the fabric main body using only a plurality of wefts.

Further, the plurality of wefts form an original image of the woven fabric.
Expressed the warp overlap in the vertical direction with respect to the surface to be covered in multiple Runode can peek the other weft from the gap of one weft, thus the conventional multiple wefts are arranged in the same plane The expression of various colors is possible with fewer wefts than those of.

Further, if a plurality of wefts are provided with a warp different from the warp on the surface side representing the original image of the woven fabric main body, it is possible to prevent the wefts located on the surface of the woven fabric main body from floating due to the warp yarns. In addition, the weft can be securely locked to the surface of the woven fabric body.
