Problems solved by technology

However, in the process of pattern design, the process of pattern creation and modification relying on the human brain is very cumbersome and often becomes a bottleneck in product design, which is difficult to meet the needs of modern production models
[0005] Before the present invention was made, in the document "Geometric Two-square Continuous Pattern Design Based on Peano Curve" ([J] Silk 2007, No.1, p.16-18), a method for generating a Peano curve was involved, the steps Including: using the L-Systems algorithm, first define the initial form as an alphabet or a symbol string, and then replace each initial character with a new character form according to the iterative rewriting rule, and perform repeated replacement and rewriting in this process, and finally To generate graphics, according to the method disclosed in the text, the obtained Peano curve is the basic graphics, and the color and width of the lines in the graphics cannot be changed, so the graphics with style changes cannot be obtained

Embodiment 1

[0037] One: Construct the Peano curve according to the composition principle of the fractal L system.

[0038] Use a ternary formula L= , Used to represent the object to be constructed. Among them, symbol set G={F,+,-,X,Y}; starting symbol element W=X; generating rule set P={F→F, X→-YF+XFX+FY-, Y→+XF -YFY-FX+, +→+, -→-}; recursion depth n. The generator of X is "-F+F+F-", and the generator of Y is "+F-F-F+".

[0039] According to the composition method of the fractal L system, the strings with different recursion depths generated by L are shown in Table 1. When different recursion depths are taken, different pipeline-shaped Peano curves are obtained. When the recursion depth reaches a certain level, The curve fills the entire plane.

[0040] Table 1

[0041]

[0042] In computer processing, if you draw each line in a single color, you will get a binary image (the line and the background are each in the same color), see attached figure 1 , It is the Peano curve diagram provided by ...

Embodiment 2

[0052] Step 1: Generate Peano curve pattern

[0053] In the program, set the drawing line width to 1.2% of the side length of the image, and use different colors to draw different line segments corresponding to the characters "F", "X" and "Y". The rest is the same as the step 1 of Example 1, and the result is as follows Figure 4 The three-color image shown.

[0054] Step 2: Edit the pattern

[0055] Cut part of the edge of the image, the resulting image is as Figure 7 As shown, the patterns are stitched up and down symmetrically. In this embodiment, the edge-cut pattern is simply modified. For example, the too long section in the figure is cut off in the CAD software to make the flower and ground layers more distinct.

[0056] Step 3: Draw an idea map

[0057] The image is divided into two colors by weaving, and different weaves are filled in different colors. In this embodiment, the ground weave adopts 5 2 flying weft surface satin weaves, and the flower weave adopts plain weave. ...

Abstract

The invention relates to a jacquard fabric designing and processing method and in particular relates to a processing method of jacquard fabric with Peano curve fractal graph textures. The method comprises the following steps: according to a fractal L system composition principle, generating a peano curve graph through computer treatment; changing the recursion depth, line drawing width, line color and the like of the peano curve graph to obtain a changeful peano curve graph; using jacquard CAD (computer-aided design) software to edit a selected pattern, and separating color, paving different textures at different color positions to obtain a pattern grid, outputting a pattern card file, then reading the pattern card file by an electronic jacquard machine to weave so as to obtain the jacquard fabric with the fractal textures. By using the method provided by the invention, the fabric with different texture effects can be conveniently and rapidly obtained by selecting the peano curve patterns with different recursion depths, different line widths and different line colors, and adopting different pattern splicing modes, different fabric textures or different warps and wefts in an unit circulation.

Description

Technical field [0001] The invention relates to a design and processing method of a jacquard fabric, in particular to a processing method of a jacquard fabric with a Peano curve fractal graph texture. Background technique [0002] When the jacquard fabric is weaving, the warp and weft weaves are changed to form a pattern. The yarn count is fine. The warp and weft intertwine up and down to form different patterns. The concave and convex patterns are more beautiful, such as flowers, birds, fish, insects, birds and animals. [0003] Jacquard fabrics are mostly used in middle and high-end clothing fabrics or home textile fabrics. They are products that combine artistry and practicality. While having a wide range of practical values, they also give people artistic edification and enjoyment through decoration and beautification of the environment. [0004] The preparation process of traditional jacquard fabrics is complicated. If you want to show delicate and colorful patterns on the fabri...
