基于全显色结构的二组纬提花织物的混色特征

 在满足两组纬全显色的条件下，通过色纬的色彩组合方式及比例来研究提花织物空间混色的色彩变化特征。以红色纬与其他基本有彩原色纬组合即红绿（RG）、红蓝（RB）和红黄色彩组合（RY）进行试样，将试样通过扫描仪输入计算机，对试样进行计算机仿真模拟，采用计算机色彩平均计算法计算扫描图和模拟图的L*a*b*色度值，比较两者的明度L*值，计算两者的色差。结果表明：两组纬全显色提花织物空间混色后其明度变化规律性强，试样实物与模拟试样之间有色差，两组纬全显色提花织物依据自己的混色特征可以建立起实用的色彩模型或色卡用于指导该类织物的设计。

Research on mixed color characteristics of double weft jacquard fabric with colored wefts

The sample fabrics were woven with colorless warp and two colored wefts,one with red,and the other with basic colors,i.e.,RG(red-green),RB(red-blue),or RY(red-yellow),and the spatial mixed color characteristics on the surface of the fabrics were investigated by varying color combinations and proportion of colored wefts.And then the sample fabrics were scanned,and mixed color effect of the scanned images was analyzed using computer.A comparative study of the L*,a* and b* chromatic values of the simulated images of sample fabrics and the control based on ″color average computation″ method showed that the change of the spatial mixed color of the sample fabrics had distinct regularity and there existed chromatic aberration in simulated images between the sample fabric and the control.In accordance of the mixed color characteristics,a color model and standard color card of the double weft jacquard fabric with colored wefts can be developed and used to guide the design of this kind of fabrics.
