摘　　要：针对彩色纤维混色过程中缺乏数字化推演手段等问题,以构建全色域网格化混色模型为目标,选取彩色三原色纤维与灰色纤维进行混色,以10%为梯度构建3组三元双重耦合混色模型;整合四基色节点与三元双重耦合混色网格点序号,得到全色域混色模型及其网格混色样的质量矩阵、混合比矩阵与颜色值矩阵;通过直角坐标与极坐标的转换,同时代入四基色彩色纤维颜色值,可得到矩形和圆形的全色域网格化混色模型及其色谱;依据构建的全色域混色模型,给出不同离散度的全色域网格化混色色谱及与之相对应的色相、明度、彩度的渐变色谱,并应用到服装面料色彩设计领域。研究表明,构建的全色域混色模型,不但可在全色域范围内获取彩色纤维的可视化混色色谱,还可为彩色纱线的数字化设计提供有效方法。In view of the lack of digital means to calculate the color mixing process of colored fiber,this paper aimed to build a full color gamut grid color mixing model.Three primary color fibers and gray fibers were selected for color mixing,and three groups of ternary double-coupled color mixing models with 10%gradient was constructed.The weight matrix,mixing ratio matrix and color value matrix of the full color gamut color mixing model were obtained by integrating four primary color nodes and three double-coupled color mixing grid point numbers.By converting cartesian coordinates and polar coordinates and substituting the color values of four primary color fibers,the full color gamut grid color mixing model of rectangular and circular panchromatic gamut and its chromatogram could be obtained.According to the constructed full color gamut color mixing model,the full color gamut meshing mixed color chromatography of different dispersion and the corresponding gradient color chromatography of hue,brightness and chroma were given,which was applied to the field of clothing fabric color design.The results showed that the constructed full color gamut color mixing model could not only obtain the visual color mixing chromatography of color fibers in the range of full color gamut,but also provided an effective means for the digital design of color yarns.
