A Method for Gradient Yarns Based on Discrete Gradient Chromatography Based on Coupling and Mixing Spinning of Four Primary Color Fibers

Abstract

Disclosed are a discrete gradient color spectrum constructed by the coupling and blending of four primary color fibers and the spinning of a gradient color yarn. The mass of four primary color fibers is taken as a carrier to construct an increasing and decreasing mass sequence, and same is combined and paired as a four primary color fiber mass coupling and blending and gradient blending model. Based on the model, a discrete gradient color spectrum of the four primary color fibers and a discrete algorithm of the draft ratio of a spun color yarn with a discrete gradient color are constructed, and the discrete gradient effect of the yarn color based on the coupling and blending of the four primary colors is obtained, and same is used to spin yarn with color serialization characteristics with a discrete color gradient, or to spin gradient color yarn with a natural color gradient effect on one yarn. Therefore, on the basis of the coupling mass ratio between the four primary color fibers, a secondary color matching between the multiple primary color fibers can be efficiently achieved, and a discrete gradient serialized color and a discrete gradient color are obtained within the full color range space, so as to accurately obtain discrete and gradient color yarns of each color corresponding to the four color fibers.

technical field [0001] The invention relates to a method for spinning gradient yarns by coupling and mixing fibers of four primary colors based on discrete gradient chromatograms, and belongs to the technical fields 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 discrete gradients ...

AI Technical Summary

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 fibers of different colors cannot be achieved in any proportion; on the other hand, the traditional color matching method can only change the mixing ratio off-line (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.
