A Method for Gradient Yarns Based on Discrete Gradient Chromatography Based on Coupling and Blending of Three Primary Color Fibers

Abstract

The invention relates to a method for spinning graded yarns based on the coupling and blending of three-primary-color fibers based on discrete gradient chromatograms. The quality of the three-primary-color fibers is used as a carrier to construct an increasing and decreasing mass sequence, and the combined pairing is used as the mass coupling and mixing of the three-primary-color fibers. Based on this model, the discrete gradient color spectrum of the three primary colors fibers and the discrete algorithm of the draft ratio for spinning the color discrete gradient color yarns are constructed, and the three primary colors are obtained based on the coupled 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. Therefore, based on the coupling mass ratio between the three primary color fibers, the secondary color matching between the multi-primary color fibers can be efficiently realized, and the serialized color and discrete gradient color in the full color gamut space can be obtained, and then the three primary colors can be accurately realized. Obtaining colored yarns with discrete gradients of colors corresponding to fibers of different colors.

Description

technical field [0001] The invention relates to a method for preparing gradient yarn by coupling and mixing three primary color fibers based on discrete gradient color spectrum, and belongs to the technical field of digital color-color spinning and color spinning. Background technique [0002] The color of textiles is basically obtained by fabric dyeing, and the color spinning in the spinning field is achieved by mixing two or more fibers of different colors to achieve color matching. Color matching is usually carried out in several ways such as pre-spinning cotton blending, bag blending, cotton box blending, drawing blending, roving blending, and spun yarn blending. [0003] In the invention patent "CN201510140466.6 Method and device for regulating yarn linear density and blending ratio by three-component synchronous drafting" proposed by the inventor, the asynchronous drafting of the three-color roving changes the color fiber content of the yarn. Blending ratio, and then ...
