Research On Color Mixing Theory Of Full-coloring Woven Fabric And Its Application

In this paper, a comprehensive analysis on color design principle and method of wovenfabric was proposed in order to resolve the issue that colour aberration is always caused andunpredictable when designing colour mixture of woven fabric. The study found that the colormixture of woven fabric under full-color structure features regularity based on the review ofrelated literatures and outcomes so far. And the scientific and practicable color experiments weredevised, including color table design and color measurement, color simulation as well as test andanalysis of mixed color effect. The study explored the general characteristic and color mixingtheory of woven fabric with double-weft and triple-weft under full-color structure. And then, thefindings of the study were put into design application of figured woven fabric.Firstly, based on in-depth analysis of woven fabric coloring theory, juxtaposition colormixture theory, additive color mixing theory, and the color space system and its measuringmethod six colors (red, yellow, green, blue, black, white) were selected as basic colours to meetthe requirement of color mixture for woven fabric design, and CIE1976L a b uniform colorspace was recognized as an ideal color space for colour quantification of woven fabric. Moreover,the study found that the “average color measurement” is one of convenient and accurate methodsfor the color measurement of woven fabric.Secondly, an innovative design was proposed based on the design principle and method offull-coloring structure. The weave databases were designed for setting up the color tables withboth double-weft and triple-weft. The fabric samples of color tables were made by using basiccolor weft, and then, were simulated and measured by both computer system and the method of“average color measurement”. The experimental results showed that practical color table or colormodel of full-coloring structure for colour design of woven fabric can be set up based on its owncolor mixture characteristics. It is of great benefit to design creations of this kind of fabrics.Moreover, the study found that the deviation between real color mixture effect and predicted effect will be reduced when designing fabric by the larger repeat weaves and/or optimizedstructure designing method.Lastly, the color table with two wefts that corresponding computer color to weave structurewas set up according to the difference proportion of color areas. This color table has6optionalbasic colors (K, G, B, Y, C, M) and12combination methods of basic colors that can be used todesign colour gradation of wefts. The effectiveness and availability of color mixture principlewere verified by colour experiment, design practice of color table and jacquard fabric withdouble-weft.This study provided not only a technical reference for color design of woven fabric that willreduce the color variation between the designing color and actual fabric color to a certain extent,but also a convenient design method for color simulative and innovative design of figured wovenfabric under full-color structure. Moreover, the study laid the foundation for research onintelligent design of woven fabric.
