Method of double-primary color fiber coupling blending and spinning to make gradient yarn based on discrete gradient chromatography

Abstract

The invention relates to a method for spinning gradient yarns based on dual-primary-color fiber coupling and blending based on discrete gradient chromatograms. The mass of dual-primary-color fibers is used as a carrier to construct an increasing and decreasing mass sequence, and the combination and pairing thereof are used as two-primary-color fiber mass coupling and mixing. Based on this model, the discrete gradient chromatogram of dichromatic fibers and the discrete algorithm of the draft ratio for spinning color discrete and gradient colored yarns are constructed, and the dual-primary colors are obtained based on coupling mixing to realize the color of the yarn. Discrete gradation effect, used for spinning yarns with color serialization characteristics of discrete gradation of color, or spinning gradation yarns with natural color gradation effect on one yarn. Based on the mass coupling mixing ratio between dual-primary-color fibers, it is possible to efficiently realize secondary color matching between multi-primary-color fibers, and obtain serialized colors and discrete gradient colors in the full color gamut space, thereby accurately realizing dual-primary colors Obtaining colored yarns with discrete gradients of colors corresponding to the fibers.

Description

technical field [0001] The invention relates to a method for producing gradient yarn by coupling and blending of dual primary color fibers based on discrete gradient chromatography, belonging to the technical field of digital toning spinning and color spinning. Background technique [0002] The color of textiles and apparel products is affected by fashion trends, and has the characteristics of short cycle, rapid change, and significant fashion effect. Textile enterprises must have fibers, yarns, fabrics and garments that can rapidly modulate and spin discrete and gradient colors of hue, lightness, and saturation to respond to fast and changing market demands with agile manufacturing and quick response. [0003] Colored spinning enterprises usually mix at least two or more fibers of different colors in the processes of cotton matching, parquet, catching, opening and cleaning, drawing, roving, and spinning to obtain discrete gradients such as hue, lightness, and saturation. s...

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.

[0007] According to the invention patent "Method and device for spinning colorful slub yarn with two-component synchronous two-stage drafting (CN104711730)" and "Method and device for regulating yarn linear density and blending ratio by three-component synchronous drafting (CN201510140466) .6)” provides the method, although the online change of the blending ratio can be regulated, but how to regulate the change of the draft ratio of the two channels to realize the coupling gradient of the weight mixing ratio of the multi-primary color fibers, and how to achieve the coupling of the multi-primary color fiber weight mixing ratio The gradient realizes the coupling gradient of the RGB value of the color spinning yarn, and how to realize the color gradient of the color spinning yarn through the coupling gradient of the RGB value of the color spinning yarn, no solution is given
