DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for weaving various woven fabrics.

[0002]

2. Description of the Related Art Shuttleless looms have been developed mainly for the purpose of improving weaving efficiency. Improvements have been made to eliminate woven flaws that tend to occur as the loom speeds up, and to improve the quality of woven fabrics. In addition, complicated woven patterns are drawn by the jacquard device, but recently, the image processing of the woven pattern is performed by using a computer, and no garment paper is required. Instead, a direct jacquard that can immediately reproduce the original image of the woven pattern on the woven fabric has been developed, and the woven pattern can be switched in a short time in response to a change in the weaving specification.

[0003]

As described above, even if the loom itself is improved so that a high-quality woven fabric can be woven, it is necessary to change the color tone of the woven pattern with the change in the weaving specification. It is necessary to switch the weft, and the yarn to be used must be prepared several weeks before, for example, by test dyeing. It takes a lot of time and effort. Of course, in accordance with the color expression method in the printing field using the fusion phenomenon of colors on the retina, five extra-fine yarns of white, black, red, yellow, and blue are prepared, and the weaving texture points of these color yarns are prepared. As a method, a method of expressing a required color by a combination of bonding points formed on the surface of the fabric can be considered. However, in order to make the joining point of the yarn appearing on the fabric surface as a cloth fine as a printing dot, an ultrafine yarn having a thickness of several microns is required, but such an ultrafine yarn is actually a woven fabric. Such a method is not feasible in practice, since it is not used.

[0004] In consideration of this point, red (R), orange (YR),
Each color of yellow (Y), yellow-green (GY), green (G), blue-green (BG), blue (B), blue-violet (PB), purple (P), and red-violet (RP) is determined by brightness and saturation. An attempt was made to express the required color on the woven fabric surface by combining the bonding points that appear on the woven fabric surface by incorporating a total of 60 colored yarns changed in six stages. Although it is possible to weave while selecting color yarns in the work, it is not possible with an automatic loom because the number of color yarns to be set is limited to 12 colors.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it possible to selectively weave dozens of colored yarns in an automatic loom, and to color a desired original image by combining the joining points of the numerous colored yarns that appear on the fabric surface. On the surface of the fabric. A second object of the present invention is to provide a desired original color on a woven fabric surface using standardized dozens of color yarns without dyeing and preparing color yarns for each original image. It is to be able to express in. A third object of the present invention is to make it possible to immediately weave a variety of woven fabrics based on the changed weaving specifications without performing a weft switching operation each time the weaving specifications change, and thereby weaving. It is an object of the present invention to eliminate time loss associated with a change in specifications and to provide a variety of woven fabrics according to demand in a timely manner.
