Spinning method for constructing discrete gradient chromatograms and making gradient colored yarns through coupling mixing of double-primary-color fibers

Abstract

The invention relates to a spinning method for constructing discrete gradient chromatograms and making gradient colored yarns through coupling mixing of double-primary-color fibers. With the mass of the double-primary-color fibers as a carrier, an increasing mass sequence and a decreasing mass sequence are constructed and then combined and paired to serve as a double-primary-color fiber mass coupling mixing and gradient mixing model, the discrete gradient chromatograms of the double-primary-color fibers and a draft-ratio discrete algorithm for spinning the color discrete gradient colored yarnsare constructed according to the model, and the discrete gradient effect of the colors of the yarns is achieved based on coupling mixing of double 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 mass coupling mixing ratio of the double-primary-color fibers, secondary color matching among multi-primary-color fibers 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 with discrete gradient colors corresponding to the fibers with the two colors are accurately obtained.

technical field [0001] The invention relates to a discrete gradient color spectrum constructed by coupling and mixing double primary color fibers and a spinning method 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] The traditional color matching method is used to mix different color fiber raw materials in the pre-spinning processes such as cotton blending, patterning, packing, opening and cleaning, drawing, roving, and spun yarn. On the one hand, it is impossible to accurately control the mixing ratio of different colored fibers , the mixing of fibers of different colors cannot be achieved in any proportion; on the other hand, the mixing ratio of fibers of different colors cannot be changed online

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

And how to realize the coupled gradient of color spinning RGB value through the coupled gradient of multi-element color fiber weight mixing ratio? Further, how to realize the gradient of the color of the dyed yarn through the coupling gradient of the RGB value of the dyed yarn? no solution given
