Color-spun yarn color matching method based on least square support vector machine

Abstract

The invention relates to a color-spun yarn color matching method based on a least square support vector machine. The method is characterized by comprising the following steps that reference color fibers are determined, and the corresponding color data value is acquired; a part of or all reference color fibers are selected, combined in different ways and mixed in different mixing ratios for spinning and sample preparation, and the reflectance values of all samples are measured; the reflectance value of a standard sample and the corresponding proportional relation serve as training samples, and an LS-SVM function model is trained; a corresponding sample recipe C is calculated; according to the prediction recipe C, sample making is conducted, a simulated sample is obtained, and the reflectance value of simulated sample is measured; through the comparison, the chromatic aberration between a target sample and the simulated sample is obtained, if the chromatic aberration meets a preset value, the proportion is determined as an optimum recipe, otherwise, recipe modification is conducted; the optimum recipe is input in an LS-SVM training set for training. The types of the reference color fibers adopted by the method are less, after the recipe obtained by calculation is verified and modified, the accuracy of the optimum recipe is high, color matching is simple and reliable, and the efficiency and the practicability are high.

Description

technical field [0001] The invention relates to a color-matching method for melange-spinning yarns based on a least-squares support vector machine, and belongs to the technical field of color-spinning computer color matching. Background technique [0002] Color spinning is to dye the fibers first, choose two or more fibers of different colors, and mix and spin them through a specific spinning process. It has a hazy and three-dimensional color mixing effect, a special appearance style, and high added value. Color spinning does not require dyeing and finishing processes, and has obvious advantages in energy saving and environmental protection. [0003] The color of colored spun yarn mainly depends on the type, color and proportion of selected colored fibers. Knitted fabrics made of colored spun yarn are very popular in the textile and garment market. The color spinning market at home and abroad is gradually expanding, the proportion of color spinning yarn in textile fabrics i...
