Description

  The present invention relates to a method for weaving a full-color pile fabric and a method for producing color sample data used therefor. For details, we use special color swatch data for weaving a full-color pile fabric with dyed yarn using a full-color original drawing such as photographs and paintings, and perform image processing to perform color reproducibility. This makes it possible to produce a full-color pile fabric with a strong aesthetic sense.

  2. Description of the Related Art Conventionally, embroidery is applied to a fabric using a pre-dyed thread and designed. In addition, as shown in Japanese Patent Publication No. 2000-45146, a design is made by weaving a pressed flower pattern between double woven silk fabrics, and as shown in Utility Model Publication No. 5-94286, towels with different patterns can be used. Weaving continuously to make color products with high added value. Printing technology is also used to print photographs and painting figures and designs on the fabric surface.

  Furthermore, pile fabrics similar to black-and-white photographs have been made using black-and-white dyed colors. This is possible by changing the pile density of the black thread based on the density of the black and white image to express the shading.

  When representing original drawings such as full-color photographs and paintings on a towel, it is usually necessary to perform color separation for each pitch of the design drawing to determine the color of the pitch and to pile that color on multiple threads. You will control the card. Since the original drawing is rewritten as a design drawing for textiles and expressed using pile yarn of several colors (2 to 4 colors), there is a limit to the color expression by single color and combination, and the planned color does not appear, It is virtually impossible to produce a full color expression with a strong aesthetic sense including reproducibility.

  On the other hand, in textiles other than pile fabrics, full-colored textiles have been researched several years ago and presented at exhibitions and the like. As a common feature of this weaving method, eight colored yarns of R (red), G (green), B (blue), C (cyan), M (magenta), Y (yellow), W (white), and K (black) are used for the weft. Although color expression is realized by using it, when expressing only by warp yarn (pile yarn) like a towel, it is difficult to divert the technology due to warp yarn density and the like.

In this case, applying the principle of subtractive color mixing and making a full-color towel fabric using CMY yarns, the colors C, M, and Y change abruptly for each pitch of about 1 to 2 mm square. The color is tight and the actual product can be simulated, but the color reproducibility is not good, the aesthetics are not higher than the actual product, and the aesthetic sense is inferior. If eight yarns are used to improve the color reproducibility, the width of the eight warp yarns reaches 3 to 4 mm, and the warp yarn pitch becomes coarse. In addition, although the color reproducibility is improved, the color change of the adjacent pitch is still severe when viewed from near, and the aesthetics are inferior.
Japanese Patent Publication No. 2000-15146, page 1, FIG. Japanese Utility Model Publication No. 5-94286, page 1, FIG.

  When creating a full-color woven fabric with dyed yarn, R (red) G (green) B (blue) C (cyan) M (magenta) Y (yellow) W (white) K ( The theory is to combine colors into logical colors such as black), but pile weaving cannot produce faithful color expression, color reproducibility is poor, and even high value-added aesthetic products can be achieved. There wasn't.

  Therefore, the present invention makes a color swatch that is formed by weaving a color that can be expressed by a combination of weaving structures by predetermining the color of an arbitrary warp yarn without processing with a logical color. Based on the data, the object is to realize a fabric of aesthetic touch color expression such as aesthetics and painting by adding a special analog touch while keeping color reproducibility faithful. In other words, instead of simulating the original drawing faithfully, the colors that can reproduce the original drawing are specially created. With the goal.

  The method of weaving the full-color pile fabric of the present invention for solving the above-mentioned problems is that dyed yarns of five colors, R (red), B (blue), Y (yellow), W (white), and K (black) are used. This is a full-color pile weaving method that repeats and arranges warp yarns and weaves jacquard. First, using the above-mentioned five color yarns, a single, two-color, three-color, and four-color total combination is added to the actual weave color. A sample S (n) is created, this real image is input as a color image, and the color, hue, lightness, and saturation corresponding to each sample number n are digitized and stored. The original color image to be taken is taken in the coordinates of the color image and decomposed into unit pitches P (ij) corresponding to the planned fabric structure, and the color, hue, brightness, and saturation of each divided pitch are determined, and each pitch is determined. The color sample number n of the color closest to that color is searched for and assigned to the assignment. And forming jacquard control data for driving the jacquard so that each pitch P (ij) is woven in the color of the color sample number (n) and controlling the loom using the formed jacquard control data. Then, a full-color pile fabric that simulates the original drawing is woven.

  The reason why W (white) and K (black) are added is that the colors W and K do not appear in the pile depending on the subtractive color mixing method. There are a total of 31 combinations of 5 colors: 1 color (5 ways), 2 colors (10 ways), 3 colors (10 ways), 4 colors (5 ways), 5 colors (1 way). If the color of the part without pile is added, it becomes 32 kinds. This is the theoretical maximum number of combinations, and the reproducibility of exceptional colors is better than the conventional three, four, or eight colors.

  In addition, the actual weaving sample is an actual towel weave with a pile, so it actually represents all the contents of the color, such as light reflection, gloss, appearance, etc., so the color reproducibility is three-dimensional, Overall better. Product color can be confirmed by pre-simulation.

  In the pitch separation of the original color drawing, color matching is performed for each pitch in accordance with the pitch P (ij) determined by the width of the weft yarn and the vertical yarn width of five colors. This color matching is performed in correspondence with the color sample number n described above. Therefore, for example, 31 colors correspond to each pitch, so that analog changes can be given to adjacent pitches. Because it is possible to reproduce colors in a feasible range, it is possible to simulate the touch of unusual color changes, and the finished full-color fabric has good color reproducibility and reproduces the actual product as it is Rather than doing it, it is reproduced with a brush touch and painting touch most suitable for pile fabrics, and can be made into a special art product with high aesthetics and paintability.

  The actual woven color sample may be modified by omitting one part of the combination. That is, even if the color reproducibility is slightly inferior, it is possible to obtain an appropriate aesthetic.

  A sample of the real weave color sample is created, this real image is input as a color image, and the hue, lightness, and saturation corresponding to each sample number (n) are not numerically stored, and the same or similar procedure is used. The created color sample data D (n) can be transcribed and used. This is the same as there is no difference from real weaving.

  The color swatch data of the present invention is created by creating a real woven color swatch of a total combination of colors that can be colored using a plurality of pre-dyed yarns on a single cloth, and creating this real image under the same imaging conditions. The color corresponding to the sample number (n) of each color is converted into a numerical value and stored, and numerical data D (n) for each sample (n) is obtained. It is also possible to change 5 threads to 4 or 6 or change the degree of color (eg red and red). Although it is basically a real woven yarn, a yarn different from the actual woven yarn can also be used. Sample data of multiple colors can be created with different threads. It can also be used by simulation. Since the overall color change can be performed by adjusting the color of the model, it is not necessary to use four colors or five colors. However, this is also useful as a weaving technique by changing to a special color. In actual weaving, the model is made to correspond to the sample, and the aesthetic expression of the finished product is confirmed while simulating the actual weaving result, the color sample is changed, and the model color is adjusted and determined.

  The present invention is a method for weaving a full-color pile woven fabric that matches the color of the unit pitch of the woven fabric based on a color swatch made by actually weaving a combination of five dyed yarns and weaves it in the same color as the swatch. Therefore, the color reproducibility is good, and the change in color can be made analog for adjacent pitches, giving it a three-dimensional appearance and aesthetics, giving it a high artistic value and high added value. Can weave the fabric. According to the sample of rich colors, it can be an art product that gives a unique touch to the pile.

  Even if the number of the five colors and the number of combinations is changed, an art product having a corresponding color change can be obtained.

  The method of creating color sample data of the present invention is to create a real weave color sample with a total combination that can be colored using a plurality of pre-dyed yarns on a single cloth, and this real image is a color image under the same imaging conditions. Input, color corresponding to each sample number (n) is converted into numerical values and stored, numerical data D (n) for each sample is obtained, and the colors of each pitch of the original drawing are actually woven according to the sample. It is possible to express the same color as the simulation color, and it is possible to weave a pile fabric that has good color reproducibility and the best color touch. Create multi-color swatches and weave artistic full-color pile fabrics with the best touch while changing color touch.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a system configuration for carrying out a method of weaving a full-color pile fabric according to the present invention. This system includes a color digital camera 3 or scanner that captures a full-color original image 1 such as a picture or a photograph or a real weave color sample 2 specially produced by the present invention as a color image, a computer 4 that performs image processing, and a jacquard controller 5. It is comprised with the loom 6 with.

  As the original drawing 1, a full-color original drawing or original drawing such as money, monet or picasso, ukiyo-e, landscape painting, photograph or print is selected. A mere full-color design created for pile weaving, such as a flower leaflet or a colored pattern, is not selected. This is because it is only necessary to use a normal weaving method. On the basis of the original image, a material that can give a color touch peculiar to the present invention and can make a pile product having a taste is selected. For this purpose, it is possible to make an original picture for carrying out the present invention, that is, to make a photograph or a picture.

  First, the color sample 2 will be described in detail. As one of the most preferable embodiments, one color, two colors, three colors using five dyed yarns of red (R), blue (B), yellow (Y), white (W), and black (K), Make a combination of 4 colors and 5 colors. There are 5 ways for 1 color, 10 ways for 2 colors, 10 ways for 3 colors, 5 ways for 4 colors, and 1 way for 5 colors, for a total of 31 ways.

  As shown in the figure, these combinations are actually woven as a single cloth, for example, in a size of about 30 cm × 60 cm. One section is finished to a size that can be imaged by a digital camera and a size of 3 cm to 5 cm square or more. As a result, a color sample 2 with which the weaving condition and the color condition can be visually understood is obtained. In each section of the illustrated color sample 2, combinations of colors such as RW, BW, YW... Are formed from the upper left, and yarns of the respective colors are piled.

  In the actual weaving of color sample 2, as shown in FIG. 4 and FIG. 5, a combination 5 (5-1, 5-2, 5-3...) Of five yarns is formed on a beam (not shown) At the part, the required yarn is pile 6 and one section is woven evenly. Incidentally, since one pitch that can be controlled by jacquard is 1 mm to 2 mm square, a uniform color fabric is woven as an aggregate of a large number of pitches in each section of the color sample 2 of 31 sections. If this color sample number (n) is designated, a pile fabric that is exactly the same as the color shown in each section of the color sample 2 can be finished.

  The computer 4 includes a full color image data capturing unit 7 that captures a color image captured by the digital camera 3, a color sample data creating unit 8, and a color sample data storage unit 9.

  The color sample data creation unit 8 performs color analysis on the color corresponding to each number (n) of the color sample 2, and as shown in Table 1, the hue and brightness of the color for each sample number (n). , Which determines the saturation.

As shown in FIG. 2, color data is created by inputting color data of a color sample to be created in step 201, analyzing it in step 202, and determining analysis values for each element in steps 203 and 204. Through step 205, the color samples of all numbers 1 to 31 are processed. An analysis example is shown in Table 1.

  In Table 1, each section is shown corresponding to the section of the color sample 2 shown in FIG. The numbers are 8, 11, 13, 22,... In order from the upper left, and are shown in the lowermost row of the left column of each section. RGB represents red, green, and blue elements, yy represents lightness (0 to 255), ss represents saturation (0 to 255), and hh represents hue (0 to 360). The color sample data storage unit 9 stores the values shown in Table 1.

  On the other hand, the computer 4 reads the data of the original drawing 1 fetched from the full-color image data fetching unit 7 and adjusts the color, a color adjusting unit 10, a fabric pitch decomposing unit 11, and a pitch color data creating unit. 12 and a color corresponding unit 13.

  The color adjustment unit 10 deforms and color-adjusts the captured image, and creates a design drawing to be woven from now on. For example, the scale can be changed, the color can be added, or the overall color can be changed.

  In creating a full-color fabric based on the original drawing 1, it is necessary to faithfully reproduce the color. However, this is not necessarily faithful to the original drawing 1, but to be faithful to the design drawing 10b created here. I need. This is not to print the original drawing 1 but to improve the quality of the finished pile product. Therefore, the creation of the design drawing 10b here is important, and the design drawing 10b is carefully added with the simulation in the design drawing simulation unit 10a.

  The fabric pitch decomposition unit 11 performs the pitch decomposition of the design drawing 10b. That is, a rectangular pitch P (ij) (i = 1, 2,..., J = 1, 2,...) Is set in accordance with the weft pitch of the woven fabric and the pitch obtained by combining five warp yarns. Specifically, the pitch is 1 to 2 mm square.

  The pitch color data creating unit 12 analyzes the color of the design drawing 10b for each pitch P (ij) by the same procedure as shown in FIG. The closest color is determined by comparing which number (n) is closest. That is, the number (n) of the color sample 2 is associated with each pitch P (ij), stored in the pitch corresponding data storage unit 14, and stored in the jacquard data storage unit 15 as a control signal. Specifically, as shown in FIG. 3, pitch data is input in step 301, compared in step 302, color number (n) is associated in step 303, and repeated until the entire fabric pitch is completed in step 304. .

  This data is performed while determining whether the finished product is optimal as a product while observing the finished color of the finished product while simulating with the corresponding color simulation unit 14a. Since the product drawing 14b by this simulation changes corresponding to the design drawing 10b, the design drawing 10b of the design drawing simulation unit 10a is changed and repeatedly examined.

  As described above, since the product drawing 14b set by the product drawing simulation unit 14a is stored in the jacquard control data storage unit 15, the drawing, that is, each pitch P (ij) is designated as a specified color sample (n ) The data is completed to weave with the color.

  After that, data is set in the jacquard control device 5 and the loom 6 is driven to complete the fabric as shown in the product diagram 14b designated in the pitch correspondence data storage unit 14. At this time, the full-color product diagram 14b simulated by the corresponding color simulation unit 14a is the same as the full-color diagram woven by the loom 6, and the color reproducibility is certain as long as this is the case. In the present invention, it is possible to generate a color suitable for a product by changing the touch of the color while ensuring the color reproducibility without simulating the original drawing 1 as it is. Thereby, product quality can be improved.

  FIG. 4 shows a specific example of the weaving method of the loom 6 based on the product diagram 14b. As shown in the drawing, five colors of RBYWK yarns are repeatedly arranged on a beam (not shown), and these are sent as warp yarns 16 (16-1, 16-2, 16-3,...). Using the upper thread, the weft thread 17 and the lower thread 18, the jacquard is activated for each color and lower thread of the upper thread, and the designated upper thread is piled 19 for each pitch according to the jacquard control data. As shown in an enlarged view in FIG. 5, the pile 19 is entangled with three weft yarns with respect to the ground yarn 20 and protrudes on one surface, and a portion that is not piled protrudes on the other surface.

  As shown in FIG. 6, when the design drawing 10 b is a product drawing 14 b according to the present invention, an analog sensation can be obtained without a sudden color change for each pitch due to the classification of 31 colors. The product drawing 14b of the present invention is analog, has good color reproducibility of the original picture 1, and has high artistic added value. On the other hand, as shown in FIG. 8, the conventional eight-color processing is an image in which the change for each pitch is severe and the eyes flicker visually, and it is digital and imitates the original figure 1 in any way. It is an image and its artistic value as the product diagram 14b is low. When the color is changed through the design drawing simulation unit 10a, there is no color reproducibility with respect to the original drawing, but the artistic value of the product drawing 14b can be increased.

  In the embodiment described above, the weft yarn 17 was not touched, but a pre-dyed color can be used for the weft yarn 17 as a back color. Moreover, although the example which piles only a warp yarn was shown also as a weaving method, it is applicable to the various weaving methods used conventionally.

  As shown in FIG. 7 (a), the type of the actual weaving thread is changed in the same combination as the color sample 2 shown in FIG. 1, for example, red is red, yellow is magenta, etc. Even if it exists, it can be changed to indigo, or the color of the thread can be changed to make a different sample 2A. Since this is actually woven after being simulated by the product drawing simulation section, it is possible to weave a full-color pile fabric by changing the color tone of the design drawing. Color samples 2 and 2A can be used alternately. Multiple kinds of products can be made by changing the color tone. For pile yarn, subtractive color mixture cannot be applied as it is. It should be woven while confirming the aesthetic color sensation using the actual weave sample 2.

  As shown in FIG. 7B, it is possible to omit one part of the color samples 2, 2A, for example, one part (RBYK) of a part having many similar colors. Although the color reproducibility is slightly inferior, it is possible to make a similar product of the present invention.

  Further, as shown in FIG. 7C, red (R) is white (W), and it is possible to make a sample 2C that is colored with five threads of four colors. In this way, there are two white (W) lines, and in particular, it is possible to develop applications for expressing winter scenery and the like. However, in this case, of course, the actual weaving yarns must be set to five of four types according to these colors. By adding these color swatches 2C and holding them together with a plurality of color swatches 2, 2A, 2B, etc., it is possible to weave a full-color pile fabric as a predetermined artwork by selectively using them.

  In the above-described embodiment, the color is referred to as full color and includes all colors including RGB. However, the present invention is a combination of colors other than R (red), G (green), and B (blue), for example, only W (white) and K (black). But it can be done. That is, a W (white) yarn and a plurality of K (black) yarns (for example, five) yarns (for example, true black and four mice) are combined to represent a black picture realistically. In this case as well, 31 different color swatches are made with a combination of 6 yarns of 5 colors, and the primary color is simulated, so the black color as simulated in the product diagram 14b as shown in the original figure or modified by it is modified. It is possible to create a high-value-added towel art product.

  The present invention is not limited to the above-described embodiment, and various design changes can be added without departing from the gist of the present invention, and the invention can be implemented in various modes.
