TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing a weave structure for producing a weave structure for controlling warps and wefts in the process of weaving an original figure into a woven fabric.
[0002]
[Prior art]
In the weaving texture generation method, in a commonly used fabric design system, a woven original texture (design) is used to fabricate a previously prepared weaving texture (a combination of a front texture and a back texture prepared so as not to cause a defect). A method of applying by a profession called a designer, and a method of applying a woven structure capable of expressing the colors of pixels prepared in advance to an original drawing color-coded for each pixel in generating a woven structure generally called a picture weave. Each of these methods has a conceptual configuration in which a previously prepared woven tissue is applied to an original drawing.
[0003]
[Problems to be solved by the invention]
In the concept of applying the prepared woven structure to the original drawing in this way, at the stage of the original drawing, a simple and planar design configuration is mainly used, and it looks like there is a prepared woven structure prepared in advance. . However, the work of applying the woven structure according to the colors existing in the original drawing is mechanical, and it is difficult to sufficiently reflect the designer's image and aesthetic features of the original drawing on the woven fabric depending on the limited existing woven structure. The designer of the original drawing and the designer of the fabric are separated from each other, and it is up to the designer of the fabric to decide which color of the original drawing to apply to which weaving structure. As a result, reproducibility is lost.
[0004]
[Object of the invention]
Therefore, an object of the present invention is to express an original drawing as it is without being bound by the weaving structure of an existing fabric, and to directly reflect the image of the designer of the original drawing on the fabric.
[0005]
[Means for Solving the Problems]
According to the method for producing a woven texture according to the present invention, (1) the woven structure has a multi-layered structure of at least two layers of front and back sides in which wefts constitute a surface material and a lining, and (2) an original drawing to be woven is divided vertically and horizontally by meshes. (3) Each mesh of the original image is defined as a surface texture point, and the surface texture point at which the color of the adjacent mesh is switched is defined as a surface-weft junction where warp and weft turn over. Some of the weft binding points are used as surface warp binding points at which warps appear on the surface, and the original image is used as the weave organization chart of the outer fabric (face weave organization chart). On the back side, the warp and the weft that do not appear in the mesh of the dressing structure diagram constitute the design point on the back side, and the warp that does not appear in the mesh of the dressing texture diagram appears on the back surface of the fabric and becomes the back warp binding point. The back woven structure shall be formed, and the connection points shall be The total number of front and rear warp binding points of the warp is set in advance, and the back side warp binding points are arranged by calculation according to the set value (total number) of the binding points (back side weave structure diagram (back) Woven organization chart).
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
The shape of the grid that divides the original drawing vertically and horizontally is not particularly specified, and may be any of a square, a rectangle, and a round shape. On a computer screen, the pixel itself plays the role of the grid, and is thus formed by a line called a grid. May not be provided. That is, the mesh may have color information of the yarn (warp and weft) used for the woven fabric.
[0007]
If an image drawn with a color that can be expressed as a woven fabric, that is, the color of the warp and the weft used for the woven fabric, or a mixed color that mixes those colors is used as it is as the original drawing, those colors can be expressed An original image having a mesh function represented by color information of various colors is prepared to form a texture diagram. In the original drawing drawn with full color data like a painting, the color of the warp, the color of the weft, and the mixed color used in the fabric are used as palette information by the color reduction / redisplay method (dither method) used in image processing. Converted to an image, an original image having a mesh function represented by the color information of the colors that can be represented (warp color, weft color, mixed color of warp and weft) is prepared and made into a weave texture chart. .
[0008]
FIG. 1 is an image in which a painting is converted into an image having, as palette information, a warp color, a weft yarn color, and a mixture of these colors, using a color reduction / redisplay method (dither method). Portion A is shown enlarged in FIG. In FIG. 2, several kinds of weft colors (14.15.16.17.18.19) used for the fabric indicated by spots 14, horizontal lines 15, vertical lines 16, black 17, lattice meshes 18, and left-downward slanting lines 19 are shown. Is converted into an image having palette information of three kinds of warp colors (11, 12, and 13) used for the fabric indicated by the double circle 11, the right-downward slanting line 12, and the diagonal mesh 13, and the part A of the painting is A top weave organization chart is constructed, and the first mesh is composed of one cycle of weft color arrangement (14.15.16.17.18.19) and one cycle of warp color arrangement (11.12.13). ). As shown in FIG. 4, in the surface weave organization diagram, the location where the color of the adjacent mesh is switched is the surface-weft connection point where the warp and the weft are turned over. FIG. 2 shows only the surface warp binding points at which the warp (11.12.13) indicated by the double circle 11, the right-downward slanting line 12, and the diagonal mesh 13 appear on the surface. 3 is rewritten as the warp information into the dressing organization chart shown in FIG. FIG. 4 is a cross-sectional view of a woven fabric showing an interlaced structure of a warp and a weft constituted by the lowest design point and the connection point in FIGS. 2 and 3.
[0009]
The woven fabric information shown in FIGS. 2 and 3 includes the information that the warp and the weft appearing on the surface of the woven fabric form the weave, and the portion that does not appear on the surface of the warp and the weft is arranged on the lower side (back side) of the weave. Only the backing weave structure preliminary information to be made, and a stable fabric is not formed. Therefore, on the back side of each cell in the dressing texture diagram, the warp and weft that do not appear in the cells in the dressing texture diagram constitute the texture points on the back side, and the warps that do not appear in the cells in the dressing texture diagram are on the back of the fabric. To form a back weave design that becomes a back warp binding point, and in configuring the binding point, the total number of the surface warp binding point and the back warp binding point of each warp is set in advance. According to the setting value (total number) of the joining points, a weave organization diagram (back weave organization diagram) of the lining in which the back warp joint points are arranged is created by calculation. Specifically, the area B of the weave diagram of FIG. 3 will be described in detail. In the area B, the warp 11 indicated by a double circle forms three surface warp connection points and is indicated by a hatched line to the right. The warp 12 forms one surface warp binding point, and the warp 13 indicated by the diagonal mesh 13 does not form the surface warp binding point, and the shrinkage of those warps (the warp of the warp with respect to the length of the woven fabric) (Ratio of length) is not uniform, and the fabric becomes unstable. Therefore, two warp binding points on the back side of the warp 12 indicated by the oblique line to the lower right where two front warp binding points are missing from the warp 11 indicated by the double circle are added to the warp 11 indicated by the double circle. On the other hand, three back warp binding points of the warp 13 indicated by the diagonal mesh lacking three surface warp binding points are respectively provided in the back weave organization chart, and the surface warp binding points and the back warp binding of those warps are provided. Align the total number of nodes. FIG. 5 shows the back warp binding points of the warp yarns 12 and 13 provided in the area B of the weave diagram of FIG. 3 by a thick right-down diagonal line (12P) and a thick cross-hatched line (13P), respectively. Things. The adjustment of the shrinkage of the warp based on the back warp binding point is performed for each warp based on the set value of the binding point over the entire woven fabric, thereby forming the back weave structure of the lining.
[0010]
In the original drawing drawn for textiles, there is no problem because the designer created the image of the length of the warp and weft floating on the surface, but it was drawn without being aware that it will be expressed on the fabric When a general painting is used as a design source, a portion where the same color continues vertically and horizontally may occur in the original image. However, even in such a case, warp yarns of low lightness color and high lightness color are used, and if the image processing is performed in consideration of the lightness values of the low lightness color and the high lightness color of the warp yarns to be used, the warp and the weft yarns may have The problem of "floating" that continues to float for a long time does not occur.
[0011]
【The invention's effect】
According to the present invention, in comparison with the conventional method of applying the existing woven structure to the original drawing, the original drawing drawn in a color that can be expressed as a woven fabric, that is, the colors of the warp and the weft used in the woven fabric and the colors are mixed. The design itself drawn in the mixed colors is used as a surface texture diagram, and the warp and weft yarns that do not appear on the surface of the fabric in the original image (design) and are in a non-textured state are connected to the surface warp connection point and the entire fabric. The back woven structure is formed by the setting value of the point and the back warp binding point calculated based on the warp shrinkage ratio and the arrangement corresponding to the surface weave structure, and the woven structure of the entire woven fabric is generated. Without being bound, the fabric designers with different sensibilities from the designers of the original drawing have escaped from the traditional division of labor style that assigns existing woven tissues to pixels with their own sensibilities, without relying on fabric designers, original Creating a designer sensibility (image) direct to can be reflected in the fabric, spread the width of the aesthetics that are represented by the fabric.
