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.
