The invention relates to a
spinning method for constructing discrete gradient chromatograms and making gradient
colored yarns through
coupling mixing of fibers in four primary colors. With the
mass ofthe fibers in the four primary colors as a carrier, an increasing
mass sequence and a decreasing
mass sequence are constructed and then combined and paired to serve as a mass
coupling mixing and gradient mixing model for the fibers in the four primary colors, the discrete gradient chromatograms of the fibers in the four primary colors and a draft-ratio discrete
algorithm for
spinning the color discrete gradient
colored yarns are constructed according to the model, and the discrete gradient effect of the colors of the yarns is achieved based on
coupling mixing of the four primary colors; the method is used for
spinning color discrete gradient yarns with color
serialization characteristics or spinning the gradient
colored yarns with the natural
color gradient effect on each
yarn. Based on the coupling
mass ratio of the fibers in the four primary colors,
secondary color matching among fibers in multiple primary colors can be efficiently achieved, discrete gradient serial colors and discrete gradient colors in a
full color gamut space are obtained, and therefore the colored yarns in discrete gradient colors corresponding to the fibers in the four colors are accurately obtained.
