Description

七基色纤维全色域混色模式及圆环状网格化配色模型构建及彩色纱纺制方法Construction of full color gamut color mixing mode and circular grid color matching model of seven primary color fibers and method of spinning colored yarn

技术领域Technical field

本发明涉及七基色纤维全色域混色模式及圆环状网格化配色模型构建及彩色纱纺制方法，属于纺织技术领域。The invention relates to the construction of a seven-primary color fiber full color gamut color mixing model and a circular grid color matching model and a method for spinning colored yarn, and belongs to the field of textile technology.

背景技术Background technique

在现有的纺纱工艺流程中，从染色纤维、原液着色纤维或者天然彩色纤维中优选不同色彩的纤维作为基色纤维，通过手工混和、拼花混和、棉包混和、并条混和、粗纱混和、细纱混和等手段纺制色纺纱或彩色纱。In the existing spinning process, fibers of different colors are selected as the base color fibers from dyed fibers, solution-dyed fibers or natural colored fibers, and are blended by hand, parquet blending, cotton bale blending, drawing blending, roving blending, and spun yarn blending. Mixing and other means are used to spin colored yarn or colored yarn.

色纤维的配色设计及纱线的色彩创新是色纺纱生产过程的关键技术之一，通常采用三原色配色法或者主色加辅色配色法。现有色纺纱生产流程中存在问题：一是纤维染色配色与色纱纺制相互脱节；二是以点对点的碎片化手工配色配色为主；三是基于三原色配色的色彩还原不够丰富；四是缺乏对色相、明度、彩度进行统一调控的理论与方法。由于传统配色依靠操作人员的经验对色彩的色相、明度及彩度进行把握，造成配色结果受人的主观影响较大，且配色准确性弱、配色效率低、配色周期长等现状。The color matching design of colored fibers and the color innovation of yarns are one of the key technologies in the production process of colored spinning. The three primary color matching method or the main color plus auxiliary color matching method is usually used. There are problems in the existing color spinning production process: first, fiber dyeing and color matching are disconnected from color yarn spinning; second, point-to-point fragmented manual color matching is mainly used; third, the color restoration based on three primary color matching is not rich enough; fourth, there is a lack of The theory and method of unified control of hue, lightness and chroma. Since traditional color matching relies on the experience of the operator to grasp the hue, brightness and chroma of the color, the color matching results are greatly affected by human subjectivity, and the color matching accuracy is weak, the color matching efficiency is low, and the color matching cycle is long.

由于色彩是由色相、明度及彩度三个维度组成的向量，为了满足色彩还原的丰富性以及多层次色彩明度、彩度的需求，需要开发六彩基色加一灰基色的七基色配色法；为了提升配色准确性，需要开发基于算法的计算机自动配色技术。Since color is a vector composed of three dimensions: hue, lightness and chroma, in order to meet the richness of color restoration and the needs of multi-level color lightness and chroma, it is necessary to develop a seven-primary color matching method of six primary colors plus one gray primary color; In order to improve the accuracy of color matching, algorithm-based computer automatic color matching technology needs to be developed.

In practical application, in the process of color matching, color mixing and dyeing of textiles, it is necessary to consider the three dimensions of hue, lightness and saturation. For color control, generally two groups of adjacent colors are used to mix colors to control hue changes, one group of colors and one group of achromatic colors are used to mix to control brightness changes, and two or more groups of adjacent colors and one or more achromatic colors are used to mix the chroma.

The weights of these seven groups of primary color fibers are respectively W _α , W _β , W _γ , W _δ , and W _ε , W _ζ ,W _O .

Based on the preset reference discrete number corresponding to the fiber quality, six three-dimensional color mixing combinations are composed of any two color fibers and gray fibers among the seven primary color fibers, and the corresponding three-dimensional color mixing combinations are constructed. The top grid is gray and the two bottom grids correspond to the two-color ternary coupled color mixed mass pyramid grid model, and then enter step C.

根据式(2)可知，七基色纤维三元组合混色各子样的重量与基色纤维的基准重量有关，与基准离散数有关，还与离散序号有关。如果混色过程中，对基色纤维基准重量、基准离散数和离散序号不加约束，则混合子样的重量，W _oβα(j ₁,j ₂,j ₃),W _oγβ(j ₁,j ₂,j ₃),W _oδγ(j ₁,j ₂,j ₃),W _oεδ(j ₁,j ₂,j ₃),W _oζε(j ₁,j ₂,j ₃),W _oαζ(j ₁,j ₂,j ₃)是一个非恒定的变量。为了分析混色过程中色纤维混合比例对最终混色色彩的影响，需要使各混合子样重量为恒量，从而可以单因素方式考察三原色纤维混合比对混合色彩的影响。为此需要建立对基色纤维基准重量、基准离散数和离散序号的约束条件，以保障混色过程中各混合子样的重量保持恒定。 According to formula (2), it can be seen that the weight of each sub-sample of the three-dimensional combination of seven primary color fibers is related to the reference weight of the primary color fiber, the reference discrete number, and the discrete serial number. If during the color mixing process, there are no constraints on the base weight, base discrete number and discrete sequence number of the primary color fiber, then the weight of the mixed sample, W _oβα (j ₁ ,j ₂ ,j ₃ ), W _oγβ (j ₁ ,j ₂ , j ₃ ),W _oδγ (j ₁ ,j ₂ ,j ₃ ),W _oεδ (j ₁ ,j ₂ ,j ₃ ),W _oζε (j ₁ ,j ₂ ,j ₃ ),W _oαζ (j ₁ ,j ₂ ,j ₃ ) is a non-constant variable. In order to analyze the influence of the mixing ratio of colored fibers on the final mixed color during the color mixing process, it is necessary to make the weight of each mixed sample constant, so that the influence of the mixing ratio of the three primary color fibers on the mixed color can be investigated in a single-factor manner. To this end, it is necessary to establish constraints on the base weight, base discrete number and discrete sequence number of the primary color fiber to ensure that the weight of each mixed sample remains constant during the color mixing process.

为此定义耦合混色的定义如下：多元基色纤维各离散重量进行组合混色过程中，设各基色纤维的基准重量都相等，其基准离散数也都相等，当各基色纤维的离散序号满足特定约束条件时，可保证多基色纤维混色子样的重量保持恒定且与其基准重量相等，并使多基色纤维的混合比在0％～100％范围内梯度变化，把满足该条件的多元基色纤维的混合模式定义为多元基色纤维的耦合混色。For this purpose, the definition of coupled color mixing is as follows: In the process of combined color mixing of discrete weights of multi-element primary color fibers, it is assumed that the reference weights of each primary color fiber are equal, and their reference discrete numbers are also equal. When the discrete serial numbers of each primary color fiber satisfy specific constraints When , it can be ensured that the weight of the multi-primary color fiber mixed color sample remains constant and equal to its base weight, and the mixing ratio of the multi-primary color fiber can be gradient changed in the range of 0% to 100%. The mixing mode of the multi-primary color fiber that meets this condition It is defined as the coupled color mixing of multi-primary color fibers.

基于颜色科学及其色彩学理论，颜色包涵色相、明度及彩度等三个维度。色彩的调控及配色，通常要从色相、明度及彩度等三个维度在全色域范围内进行调控。色彩的全色域是由0°～360°变化的色相角、0～1变化的明度、0～1变化的彩度所定义的颜色空间决定的。所谓色彩的全色域调控，是指基于调控多元基色比例，实现色相角在0°～360°范围内变化、明度在0～1范围内变化、彩度在0～1范围内变化的色彩调控方法。Based on color science and its color theory, color includes three dimensions: hue, lightness and chroma. Color control and matching are usually controlled within the full color gamut from three dimensions: hue, lightness and chroma. The full color gamut of color is determined by the color space defined by the hue angle that changes from 0° to 360°, the lightness that changes from 0 to 1, and the chroma that changes from 0 to 1. The so-called full color gamut control of color refers to the color control that realizes the change of hue angle in the range of 0° to 360°, the change of brightness in the range of 0 to 1, and the change of chroma in the range of 0 to 1 based on the control of the proportion of multiple primary colors. method.

前述构建的耦合混色网格化模型包涵15个网格点，通过变动网格点坐标可变更七基色彩色纤维α,β,γ，δ,ε,ζ,o的混合比例，并分别在α-β-0,β-γ-0,γ-δ-0,δ-ε-0,ε-ζ-0,ζ-α-0等六个色域范围内调控色彩的色相、明度及彩度的变化。但上述调控手段属于局部色域调控，无法在全色域范围内调控颜色的色相、明度及彩度变化。为了能在全色域范围内调控颜色变化，实现色相、明度、彩度的数字化精准调控，需要构建全色域的网格化混色模型。The coupled color mixing grid model constructed above contains 15 grid points. By changing the coordinates of the grid points, the mixing ratio of the seven primary color fibers α, β, γ, δ, ε, ζ, and o can be changed, and the mixing ratios of the seven primary color fibers α, β, γ, δ, ε, ζ, and o can be changed respectively in α- Control the hue, lightness and chroma of colors within six color gamuts: β-0, β-γ-0, γ-δ-0, δ-ε-0, ε-ζ-0, ζ-α-0. Variety. However, the above control methods belong to local color gamut control and cannot control changes in hue, brightness and chroma of colors within the full color gamut. In order to control color changes within the full color gamut and achieve precise digital control of hue, brightness, and chroma, it is necessary to construct a gridded color mixing model for the full color gamut.

为此，将六个网格化子模型对应各行首尾相互拼接得到一个由七基色纤维构建的包涵彩色色相α,β,γ，δ,ε,ζ和灰色O等七基色的全色域网格化混色模型，该模型共有61个网格点。通过变动网格点坐标可变更七基色纤维α,β,γ，δ,ε,ζ,o的混合比例，并在α-β-γ-δ-ε-ζ-o全色域范围内统一调控颜色的色相、明度及彩度变化。To this end, six gridded sub-models are spliced end to end corresponding to each row to obtain a full color gamut grid constructed from seven primary color fibers that contains color hues α, β, γ, δ, ε, ζ and gray O. The mixed color model has a total of 61 grid points. By changing the coordinates of the grid points, the mixing ratio of the seven primary color fibers α, β, γ, δ, ε, ζ, and o can be changed, and can be uniformly controlled within the full color gamut of α-β-γ-δ-ε-ζ-o. Changes in hue, lightness and chroma of colors.
