2. Description of the Related Art The procedure for making a yarn-dyed fabric is to determine the yarn (color, thickness, twist), weave design (plain weave, saori, satin weave, etc.), yarn arrangement (combination of warp and weft), density. (Count, standard density). By combining these, weave (weave) the fabric exactly as the designer intended.
However, since there are a large number of elements and combinations, the impressions and finishes (feeling, hue, pattern, etc.) received will differ even if only one of them is different. In particular, the color of the yarn is important in the woven fabric, and even if only the warp and the weft are sufficient, when the fabric becomes a woven fabric, the combination of the warp and the weft gives different feelings and patterns.

For example, there are innumerable combinations of a plurality of yarns (hereinafter referred to as a weaving unit) in accordance with the weave design of warp yarns, and even if the order of each yarn is changed, a completely different color pattern is obtained. , Changing the number of colors makes it a different thing. The same applies to wefts, which is the reason why more combinations of warp and weft are created, and designer-specific color designations and combinations are born, and these subtly different shades can express originality.

However, in order to express colors on a computer, the characteristics of color CRTs and color printers should be well understood, and the designer can specify the density unit normally used, the number of colored threads, and any registered color. I can't find a system that I can call.

It is composed of a logical operation unit 16 that logically operates the expression data of the sprue yarn generated by the sprue yarn expression generation unit 14, and a color data generation unit 17.

2 to 3 are process flowcharts of the surface pattern pattern forming apparatus for the dyed dobby fabric of the present invention.
Shows a flow of the entire system, and FIG. 3 shows a block flow of array input. Hereinafter, the present invention will be described in detail with reference to these flowcharts.

Printer Selection (Step 21) In this step, the density N of the color printers to be used is
Enter (dots / inch).

User color registration (step 22) In this step, when the user (person in charge) changes,
When you want to perform a new color registration entirely, such as when you want to set the initial state all at once, create a new user color and register it.
Output a color sample. In addition, the registered name that is no longer needed is canceled and deleted.

Input of Thread (Step 23) In this step, the tablet 8 is used to indicate the type of thread, that is, whether it is a single-color twisted thread or a two-color twisted thread, according to the menu on the work screen displayed on the color CRT 4. Input to the control unit 1. In the case of a two-color twisted yarn, the twisting direction and the number of twists of the yarn are input by the keyboard 7.

Tissue input (step 24) In accordance with the menu of the work screen displayed on the color CRT 4, information on forward feeding and glass feeding is input to the control unit 1 using the tablet 8 in order to specify the weave. .. In case of forward order, enter the basic organization data, and in case of debris, enter the basic organization and method data.

FIG. 4 is a diagram showing the basic structure of a woven fabric,
The figure (a) shows a plain weave, the figure (b) shows a twill weave, and the figure (c) shows a satin weave. In the figure, black lines are warp yarns (warp yarns) and white lines are weft yarns (weft yarns). Figures (d) to (f) are schematic diagrams in which a part (chain line portion) of a plain weave, a twill weave, and a satin weave are enlarged, and, for example, in the case of a plain weave, as shown in (d), The basic structure in which wefts are alternately arranged is used as a unit. In Figs. (D) to (f), the portions painted in black indicate that the warp appears on the weft.

Array Input (Step 25) Array input will be described in detail below with reference to FIG.

(1) Designate the density of warp and weft in inches or centimeters (step 251) 1) According to the menu of the work screen displayed on the color CRT 4, the color information is input to the tablet in order to input the arrangement. 8 to input to the control unit 1. The work screen becomes "Arrangement input", and items necessary for arrangement of warp and weft appear. 2) The density of warp and weft, which is the basis of the woven fabric, is only in inches (MKS type) by the loom. However, with the adoption of the CGS system, thinking in centimeters has become the standard. For this reason, it is necessary to handle both inches and centimeters, and it is desirable that the designer can select them. 3) In the "Unit designation" menu on the work screen displayed on the color CRT 4, picking inches or centimeters with the tablet 8 allows you to select your preferred unit, and the subsequent warp and weft numbers will be the selected units. Treated as a hit,
Input from the keyboard 7. 4) For example, pick inches in the "designated unit" of FIG.
When 60 warps and 100 wefts are input, the density of the woven pattern is 60 warps / inch and 100 wefts / inch. This density is displayed on a color CRT and printed on a color printer.

(2) The color is designated by the registered color name (steps 252, 253, 254) 1) Each designer holds the color of the thread and the name of the color individually. Therefore, it is difficult to use only the uniform color and color name, and it is difficult to express a subtle difference in color. 2) Therefore, it is necessary to register and change the color and color name (registered name or color number) for the designer in "user color registration" (the applicant of the present application, the 1991 patent application). 282104). 3) Even in the "array input", by inputting this registered color name, the specified color and color CRT
It is important to be able to display above. Both the warp yarn arrangement and the weft yarn arrangement are displayed immediately after the color name on the color CRT. 4) If the color name does not match the registered name or number, you are prompted to enter it again, and if it still does not apply,
Pick "Menu" and finish "Array Input".

(3) Arbitrary designation of color arrangement of warp and weft (steps 252, 253, 254) 1) Input of warp arrangement and weft arrangement (hereinafter referred to as yarn arrangement) is the same, which is easy to use. ， It is intended for convenience. 2) The normal yarn arrangement is designed with the loom in mind. Therefore, it is sufficient to handle a maximum of eight types of threads. For this reason, as shown in FIG. 5, indexes indicating the positions A to H are added in the vertical direction on the color CRT so as to prevent an error. 3) In the horizontal direction, the number of threads corresponding to each color name is 14
You can enter up to the points. The end (far right)
The total entered in is calculated. There are usually no inconveniences if there are 5 to 10 weaving units. 4) For example, color numbers 4625 and 4913, registered name red 1
If you specify 2, 2 and 10, respectively, color C
When the pen is moved on the tablet while watching the RT, the input position is picked and determined, and the number is input from the keyboard, as shown in FIG. The number 14 in the number of times column is an important number that is the total number of threads in the weaving unit. 5) By comparing and examining the value of this total and the density of the yarn, the woven pattern intended by the designer can be obtained. 6) When you want to change the number of threads, pick the corresponding part of the corresponding color name and reenter the number from the keyboard. 7) If you don't need or want to delete, you can delete the entire color name by putting a space at the beginning of the color name,
In the case of the number of lines, if 0 is input in the corresponding place, the line is deleted.

Simulation (color processing) (step 2)
6) FIG. 7 shows, for example, the warp yarn A of interest in a plain weave fabric design.
5 and warp yarns A1, A3, A7, A9 and weft yarns A around them
It is a surface view of the textile structure which consists of 2, A4, A6, A8. The division processing unit 13 uses the expressible number of dots d, the dither z used, and the number of repetitions k obtained by the yarn expression calculation unit 12 to calculate the warp yarn, for example, A5 (referred to as a region) n (longitudinal) ×
It is divided into m (horizontal) small areas aij (the number of dots in the horizontal direction is m), and each small area is 1 in the color printer.
Configure to correspond to dots. Other warps and wefts are similarly divided into a matrix.

For each of the above-mentioned areas, the muzzle yarn expression generating section 14 determines the color to be composed and the twisting direction (right or left).
Then, based on the number of twists, the floss expression data is generated.
The color of the small area a ₁₁ of the area A5 may be determined according to an algorithm in consideration of the colors of A1, A2 and A4. A color mask process for extracting each color from the expression data of the fuzz thread created as described above is performed on the control unit 1. 1
The color data and coordinate values of the lines (M warps or N wefts) are passed to the print controller 5.

Since the color representation method on the color CRT 4 and the hard copy by the color printer 6 are different (color CRT is RGB signal, color printer is YMCBk), color display on the color CRT 4 in advance. And a hard copy by the color printer 6 are set, and for example, the RGB signals are converted into a dither pattern capable of expressing halftone and then output. By doing so, the color of which the design is determined on the color CRT 4 and the color of the hard copy by the color printer 6 which is a sample of the fabric can be matched.

Textile Printing (Step 27) The surface pattern pattern of the fabric is examined and processed by simulation and then printed on the textile. Since the simulation in which the three-dimensional effect and the texture are taken into consideration in the previous step (step 26), the print with the three-dimensional effect and the texture is output at a high speed (no processing) at the current step (step 27) on the paper. To be done.

As is apparent from the above description, the present invention has the following effects. (1) MKS type of loom (in inches) and designer C
Since it is possible to select GS type (centimeter unit) or MKS type, it is easy to use for both elderly and young people. (2) By inputting the registered color name, the specified color is displayed on the color CRT together with the color name, so that the color can be known both digitally and in analog, which is easy for the user to understand and makes no mistake. Can be prevented. (3) The input of the warp and weft arrangements is the same, which is easy and convenient to use. (4) At the time of inputting the thread arrangement, an index indicating the positions A to H is added in the vertical direction on the color CRT so as to prevent an error. (5) The total in the number of times column is an important number that is the total number of threads in the weaving unit, and the relationship between the thread arrangement and the weaving unit can be confirmed. It is easier to make woven patterns.
