Description

Detailed Description of the Invention (Field of Industrial Application) This invention is based on a warp striped pattern allocation table, a weft striped pattern allocation table, and a fabric organization chart, which are the basis for weaving yarn-dyed dobby pattern fabrics. The present invention relates to a method and an apparatus for creating a surface pattern of a textile fabric, and particularly to a method and an apparatus for creating a surface pattern in a high-density area of a textile fabric using additional threads.

(Prior art) Conventionally, in order to create the surface pattern of this type of fabric from a warp striped pattern allocation table, a weft striped pattern allocation table, and a fabric organization chart, which are the basis for weaving yarn-dyed dobby pattern fabrics, there has been a general method. The method used is to capture the weaving information two-dimensionally (two-dimensionally), and to fit the yarn attributes (thread color, thickness, material texture, etc.) at each weave point in the textile organization chart. It was determined and depicted pictorially.

(Problems to be Solved by the Invention) In the conventional method described above, the vertical relationship between the warp and weft is determined two-dimensionally to determine the threads appearing on the surface of the fabric. In so-called high-density textile areas where the amount of yarn is increased by increasing the amount of yarn, it is necessary to consider not only the vertical relationship between the warp and weft, but also the vertical relationship between warps or wefts. The threads that appear on the surface of the fabric are also determined by the textile texture relationship, so it is not possible to determine the threads that appear on the surface of the fabric using only the conventional two-dimensional relationship between warp and weft. In such cases, the creator often relied on his or her intuition. For this reason, the pattern pattern of the fabric that is actually woven may not match the pattern pattern intended by the creator. It was necessary to make a prototype of the fabric and confirm it.

In addition, conventional methods for obtaining an image of a designed textile from the weaving information without actually weaving the textile include a method that requires a lot of time to draw by hand like a painting, and a simulation method using a computer. However, with these conventional methods, it is difficult to create textiles with simple designs, or in cases where the weaving information is incomplete, such as design drawings or reproductions based on free creativity. However, it is very difficult to simulate a textile design intended for a textile structure such as a high-density textile region from the above-mentioned weaving information.

This invention was made in view of the above points, and by simply inputting weaving information based on a textile organization chart etc. into a computer, pattern patterns on the surface of textiles in high-density areas of textiles where the amount of yarn has been increased by adding yarn can be accurately determined. To provide a method and apparatus for creating a surface pattern of a yarn-dyed dobby fabric using a computer, which can be created in a short time and is easy to operate.

(Means for Solving the Problems) The gist of the production method of the present invention for achieving the above-mentioned purpose is to provide a warp striped pattern allocation table and a weft striped pattern necessary for weaving yarn-dyed dobby fabrics. The weaving information based on the layout table and the textile organization chart is input into a computer, and the types of yarns exposed on the fabric surface in the high density area of the textile due to the extra threads are determined by inputting the weaving information based on the layout table and the textile organization chart into a computer. The surface pattern of the entire fabric is created using a computer based on the weaving information, and the gist of the creating device for carrying out the creating method of the present invention is that the weaving information In a computer that has an input device, an arithmetic device that performs calculations based on information from the input device, a display device that displays the results of the arithmetic device, and a display device such as a color printer,
The arithmetic device has a means for determining the presence or absence of a high density area of fabric in the warp striped pattern allocation table, and a means for determining whether or not warp yarns in a range corresponding to standard fabric density (so-called ground density) are above weft yarns in the fabric organization chart. a determining means, a determining means for determining whether there is a plurality of warps on the weft, and a method for determining whether there is a plurality of warps on the weft;
A search means for a warp that has the largest number of wefts consecutively on top of the weft for six or more weaves in front and behind the surface pattern creation position (point) in the textile organization diagram, and an attribute of the warp searched by the search means. and a means for determining the pattern as a surface pattern.

(Operation) According to the method and apparatus of the present invention, the type of yarn appearing on the surface in a high-density area of the fabric due to extra yarn is determined by checking the condition of the yarn in several weaves before and after the planned pattern creation position based on the fabric organization chart. It is determined by Furthermore, to explain the operation of the present invention using drawings, Fig. 8a shows a fabric structure in a high density region of a fabric made of three types of warp yarns, No. 1 to No. 3, in which the amount of warp yarns is increased to three times the standard yarn amount. In the figure, the areas painted black indicate that the warp is above the weft;
is a cross-sectional view in the warp direction of the fabric corresponding to the fabric organization diagram in Figure a, the hatched portion indicates the weft, and Figure c is a cross-sectional view of the fabric surface determined by this invention based on the fabric organization diagram in Figure a. Types of threads that appear
This indicates the number. For example, at position a in the same figure, the warp threads No. 2 and No. 3 are above the weft threads, but
When we examine several weaves before and after (preferably 6 or more weaves including), we find that the No. 3 warp is consecutively on top of the warp, so as shown in Figure c, the No. 3 warp is It is judged that it appears on the surface of However, at position a in the same figure, the No. 1 and No. 3 warps are above the weft, but the No. 1 warp has 5 consecutive stitches in the back, while the No. 3 warp has 5 stitches in the front. Since the texture is continuous and the conditions are exactly the same, the threads that appear on the surface are actually determined by the attributes of the warp threads and the tension of the threads, but in order to create the surface pattern pattern, it is necessary to decide on something. , here, there are 6 tissues, 4 tissues in the front and 3 tissues in the rear, including the tissue as an example.
Regarding the texture, the one with the largest number of continuous textures of the warp above the weft was determined as the warp that appears on the surface, so in Figure c, it is determined that the warp No. 3 appears on the surface of the fabric.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a flowchart showing an embodiment of the method for creating a surface pattern according to the present invention, FIG. 2 is a block circuit diagram showing the hardware of a well-known computer used in the present invention, and FIG. The surface pattern pattern of the yarn-dyed fabric created by this method, Figure 4 is a reference diagram of the surface pattern pattern created after converting the high-density area of the fabric to a normal density area, and Figure 5 shows the pattern of the fabric. The organization chart, Figure 6, is a striped pattern allocation table for the warp and weft. First, in this example, as shown in FIG. 6, the density of the fabric is 1.
60 x 60 pieces per square inch. In addition, the weft is one type of yarn No. 5, and there is no high-density area of the fabric due to additional yarn.

There are four types of warp threads, Nos. 1 to 4, and No. 4 is a white thread, which is three times higher than the normal density range (hereinafter referred to as C area) consisting of three different types of threads, Nos. 2 to 4. density area (hereinafter referred to as A area) and double high density area (hereinafter referred to as area A) consisting of two different types of yarns, No. 2 and No. 4.
Area B) is provided.

The warp arrangement of the fabric is such that area A is repeated 9 times, area B is repeated 8 times, and No.
Area C, in which a plurality to several tens of yarns of two types of No. 4 are alternately arranged, continues, and finally area B is repeated 8 times to form a group that is repeated 10 times.

In addition, in the fabric organization chart shown in FIG. 5, the black colored portions indicate that the warp yarns appear above the weft yarns.

First, Figure 2 is a block circuit diagram showing a well-known microcomputer, which basically consists of CPU1,
Consists of RAM2 and ROM3, ROM3 has
A program is written to control the CPU 1, and according to this program, the CPU 1 receives necessary data from the input device 4 such as a keyboard, displays it on the display device 5, or simultaneously exchanges data with the RAM 2. Arithmetic processing is performed while sending and receiving, and the processed data is output to the color printer 6 or print printer 7 as necessary.

The weaving information described in the above-described textile organization chart and striped pattern table is input in advance to the RAM 2 and stored as a data table.

Next, the program written in the ROM 3 is shown in a flowchart as shown in FIG. That is, when the data of the position where the surface pattern is to be created is sent from the data table of RAM2 to the CPU1, in the first step _P1 it is determined whether or not the warp side designation of the striped pattern allocation table at that position is in the high density area. do.

If the determination in _P1 is YES, then in a second step _P2 , it is determined whether or not there are weft yarns in a range corresponding to the standard fabric density (one warp yarn) above the warp yarns in the textile organization chart.

If the determination in _P2 is YES, it is determined in a third step _P3 whether or not there are a plurality of warp threads above the weft threads. Here, if the judgment of P ₃ is YES, proceed to the fourth step.
In P ₄ , out of multiple warps, the front and back 6 including the surface pattern creation position (point) in the textile organization chart
For more than one texture, search for the warp that has the largest number of textures that are consecutively placed on top of the weft. Then, the warp attributes searched in P ₄ are used as the surface pattern pattern for the fifth
It is determined in step _P5 and output to the color printer 6 if necessary.

This output signal is also sent to the sixth step _P6 ,
At _P6 , the pattern creation position is advanced by the standard density of the fabric and sent to the next control program.

Further, if the determination in the first step _P1 is NO, it is determined in a seventh step _P7 whether or not the warp is above the weft in the fabric organization chart.

If the judgment in P ₇ is YES, proceed to the fifth step above.
In P ₅ , the attributes of the warp are determined as the surface pattern in the same way as above, but if the judgment is NO, in the eighth step P ₈ , the attributes of the corresponding weft are determined as the surface pattern, and the necessary It outputs to the color printer 6 according to the color. This output signal is also sent to the sixth step _P6 .

Furthermore, if the judgment in the second step _P2 is NO,
At the eighth step _P8 , if the decision at the third step _P3 is NO, the same decision as above is made at the fifth step _P5 .

In this way, the attributes of the threads in one row of the surface pattern pattern are determined, and the determination of the threads in this pattern row is repeated to create the surface pattern pattern of the entire fabric as shown in FIG.

In the above embodiment, the extra thread is inserted only on the warp side, but the extra thread may be inserted not only on the warp side but also on the weft side. FIG. 7 shows a flowchart for creating a surface pattern of a fabric in which additional threads are inserted in both the warp and weft, and the differences from the flowchart shown in FIG. 1 are as follows. That is, in the above embodiment, if the judgment in the first step _P1 is NO, the seventh step P1 is determined as NO.
In step P ₇ , it was determined whether the warp is above the weft in the textile organization chart, but in this flowchart, if the determination in the first step P ₁ is NO, then in the 1st step P' ₁ It is determined whether the weft side designation of the striped pattern allocation table at that position is in a high density area.
If the determination in P′ ₁ is YES, it is determined in the 2nd step P′ ₂ whether or not there is a weft yarn in the range corresponding to the standard fabric density (one weft yarn) on the warp in the textile organization chart. do.

If the determination in _P'2 is YES, it is determined in the 3' step _P'3 whether there are a plurality of wefts above the warp. Here, if the judgment of P′ ₃ is YES, the 4th step
In P′ ₄ , search for the weft yarn with the highest number of wefts consecutively on top of the warp for 6 or more weaves in the front and back in the weft direction including the surface pattern creation position (point) in the textile organization chart from among multiple wefts. do. When the corresponding weft yarn is retrieved, the attributes of the weft yarn are determined as a surface pattern pattern in the eighth step _P8 , and the weft yarns 1' to 4' are outputted to the color printer 6 as necessary. This is because a step has been added. Furthermore, in the embodiment described above, if the determination in the second step _P2 is NO, the determination is made in the eighth step _P8 , but in this flowchart, if the determination in the second step _P2 is NO, the determination is made in the eighth step P8. 1st step P′ ₁
If the judgment at the second step _P'2 is NO, the judgment is made at the eighth step _P8 .
Another difference is that if the determination at the third step _P'3 is NO, the determination is made at the eighth step _P8 .

In addition, in general textiles, both warp and weft do not have high density areas, but in such a case, this flowchart can be solved by giving priority to the high density areas on the warp side. However, instead of this, as shown in the flowchart of Figure 9,
Step P ₉ is added, and the warp and weft yarns that have the largest number of structures continuously appearing on the surface, which were searched by the fourth step P ₄ and the 4th step P' ₄ , are compared in the ninth step P ₉ to determine which one. If you search for the corresponding thread based on whether the thread has a larger number of textures,
It is possible to more accurately determine the threads appearing on the surface of the fabric.

(Effects) As explained above, since the method and device for creating a surface pattern of yarn-dyed dobby fabric of the present invention has the above-described configuration, it produces the following effects.

That is, according to the present invention, the type of yarn appearing on the fabric surface in the fabric high-density region due to the so-called extra yarn, in which the yarn amount is increased over the standard yarn amount, can be determined by, for example, Among the yarns with the longest continuous interlacing in the laid state, in other words, among the multiple warps on the weft, examine several weaves in front and behind the target weave point, and find the weave that is continuous on the weft. Since the warp threads with the largest number are determined to be the ones appearing on the surface of the fabric and the surface pattern is created, it is easier to create the surface pattern than the conventional method of creating the surface pattern by hand. In particular, since it can be created using a computer, the creation time can be extremely shortened, and it is also possible to accurately determine the type of thread appearing on the surface, which previously relied on the intuition of the operator in high-density textile areas. Therefore, there is no need to check the suitability of the surface pattern created by trial weaving the fabric, and it is possible to efficiently create a highly accurate surface pattern.
