Description

A Color Jacquard Fabric Design Method Based on Graphic Combination Expression

technical field

The present invention relates to a design method of jacquard fabric interwoven with warp and weft, in particular to a color jacquard fabric design which uses a variety of gradient graphic libraries of different shapes and its length-width multiplication graphic library to combine complex digital images and colorful decorative patterns in different ways and production method.

Background technique

At present, weaving jacquard fabric usually designs the pattern and its color matching first, then designs the fabric weave according to the number of colors of the pattern, and then lays the fabric weave into the corresponding pattern color to form a fabric structure diagram, and then enters the follow-up process. The fabric weave is not considered in the pattern design stage, and the pattern problems are no longer dealt with in the fabric weave configuration stage. Pattern design and fabric weave technology are two relatively independent design links. Secondly, the performance of fabric decorative patterns completely depends on the fabric weave. Similarly, the weave design and application of jacquard fabrics are limited to the imitation of patterns and color matching effects in most cases. Although the conventional fabric weave can make the jacquard fabric have a certain texture effect in addition to satisfying the performance of the shape and color of the pre-designed pattern, if the twill weave is used, the fabric can produce a uniform and regular oblique texture, even like a through hole. Weave, honeycomb weave, mesh weave and rib weave can make the fabric obtain more prominent tactile texture, but they are still only a kind of texture and cannot generate new graphic effects with shapes. The jacquard fabric design method provided by the present invention connects the two process links of pattern design and fabric weave design, on the one hand, it can simplify the drawing of the initial pattern, and improve the efficiency of pattern design; on the other hand, it is the secondary redesign of the initial pattern A way and a method are provided, which are helpful for changing and innovating patterns of jacquard fabrics. In addition, the present invention can reduce the dependence of fabric patterns on conventional fabric weaves, and when transforming pattern design drafts into fabric weave structure diagrams, there is a library of gradient graphics to choose from besides the way of fabric weaves. So far, there is no literature on the design and manufacture of jacquard fabrics using graphic gradients.

Contents of the invention

The invention aims at innovative design of jacquard fabrics in texture and color effects by adopting a gradient graphic library, and provides a method for designing digital jacquard fabrics with various graphic textures and color changes. The present invention forms a series of graphic databases with gradient composition relations by changing the design of simple graphics with concise shapes, and implements the graphic size increasing and enlarging design for multiple gradient graphics libraries of different shapes, and then combines and applies them in different ways , so that the graphics library can redesign the pattern multiple times, and at the same time, the gradient graphics library can be used to express the delicate color change effect of the pattern, and at the same time, the design function similar to the fabric weave can be produced. In addition, for the patterns that have completed the graphic conversion design, the reorganized structure is used to design the fabric with multiple groups of colored yarns, and the jacquard fabric with the main feature of the gradient graphic combination is obtained, which is the color expression of the digital jacquard fabric and the diversification of the graphic texture.

③Select suitable graphics from the 2-5 level graphics library of different shapes, and replace them with the pattern layer (N2) with a limited number of colors. Each pattern color has a graphic with a different shape or a different magnification to replace the design, so that each pattern color is transformed into a graphic texture that is regularly and repeatedly arranged by different graphics, and then the replaced graphics The graphic color of the texture and its background color are recolored, so that the graphic color and its background color of the graphic texture representing each original pattern color are different (F2);

④ The pattern layers (F1, F2) that have undergone graphics replacement design and re-coloring respectively are summed up in pattern colors. The number of colors in the F1 pattern layer is summarized according to the number of warp and weft yarn groups, and the total number of colors does not exceed 5 colors , and the color of the F2 pattern layer is summarized according to the design concept, or it can not be summarized, and the two layers of patterns that have been summed up by color are combined up and down to form a comprehensive graphic pattern map (Z).
