Spinning method for constructing discrete gradient chromatograms and making gradient colored yarns through coupling mixing of fibers in four primary colors

Abstract

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.

technical field [0001] The invention relates to a discrete gradient color spectrum constructed by coupling and mixing of fibers of four primary colors and the spinning of gradient color yarn, which belongs to the technical field of digital color-color spinning and color spinning. Background technique [0002] The color of textile and apparel products is affected by fashion trends, and has the characteristics of short cycle, fast change, and significant fashion effect. Textile enterprises must be able to quickly modulate and spin serialized colors of fibers, yarns, fabrics and clothing with discrete gradients in hue, lightness, and saturation, so as to respond to rapid and changing market demands with agile manufacturing and rapid response. [0003] Color spinning enterprises usually mix at least two or more fibers of different colors in the process of cotton blending, parquet, cotton picking, cotton opening and cleaning, drawing, roving, and spun yarn, so as to obtain discre...

Problems solved by technology

[0006] Using the traditional color matching method, different color fiber raw materials are mixed in the pre-spinning processes such as cotton blending, mosaic, baling, opening and cleaning, drawing, roving, and spun yarn. On the one hand, the traditional color matching method cannot accurately control different color fibers. The mixing ratio of different colors cannot be achieved in any proportion; on the other hand, the traditional color matching method can only change the blending ratio offline (Off-line), and cannot change the mixing ratio of different colored fibers on-line (On-line)

Therefore, it is impossible to achieve color gradients through the mixing of two color fibers by traditional methods.
