Description
Technical Field
The invention relates to construction and application of a color fiber six-dimensional color mixing space grid model and a grid point array chromatogram, belonging to the technical field of color mixing space grid construction.
Background
The colored fiber with different color effects can be obtained by technical means of dyeing, stock solution coloring, biological transgenosis, structural color generation and the like of textile fiber materials, colored spun yarns with certain color can be obtained by carrying out color mixing spinning on the six fibers with different colors according to a certain proportion, and theoretically, factors such as the primary color, the mixing proportion, the mixing mode, the structure of formed yarns and the like of the blended fiber have great influence on the hue, the lightness and the saturation of the colored spun yarns. The colored spun yarn is spun by utilizing the color mixing of the dyed fiber with multiple primary colors or the dope-dyed fiber, and the hue, the lightness and the saturation of the colored spun yarn are regulated and controlled by changing the proportion of the primary color fiber, so that the method is a necessary means for designing and realizing the colored spun yarn.
The production of the colored spun yarn needs to complete the color design, specification design and spinning process design of the colored spun yarn. In the color design of the colored spun yarn, the following six working procedures are generally available: (1) the color of the yarn is innovated based on the prior color system, and the colored yarn is developed. At the moment, a plurality of colored fibers in a warehouse need to be combined differently and mixed color spinning needs to be carried out according to different proportions, and a plurality of color matching schemes are selected from the serialized colored yarns in the trial spinning as new products for market promotion; (2) and (4) selecting a color system based on popular colors or personal preferences of designers to carry out yarn color innovation and develop the colored yarn. At the moment, a designer selects a plurality of groups of basic color systems for fiber dyeing according to the understanding and imagination of the color, the plurality of groups of color fibers selected by the designer are combined differently and mixed color spinning is carried out according to different proportions, and a plurality of color matching schemes are selected from the serialized color yarns of the trial spinning as new products for market promotion; (3) and (5) carrying out color copying based on the sample to develop the colored yarn. On the basis of analyzing the sample, determining which color fibers are adopted to carry out color mixing spinning according to the geometric proportion? And (4) giving the test spinning colored spun yarn sample to a client for confirmation, and determining the colored spun yarn color matching scheme after a plurality of rounds.
The core technology for producing colored spun yarns or colored yarns is a color matching scheme of optimized colored yarns, and yarn color innovation is carried out based on the existing color system, yarn color innovation is carried out based on the color system selected by personal preference of a designer, or color duplication is carried out based on a sample, so that the change rules of color hue, brightness and saturation are required to be familiar, subtle differences among colors are required to be perceived sensitively, and the color matching skill of the colored yarns is required to be mastered.
At present, the design of a color matching scheme is mainly carried out by depending on personal experience and intuition of a designer, the completion of the color matching process mainly depends on manual sample preparation, manual dyeing and manual color matching, and the evaluation of the color matching result mainly depends on the observation of a real sample on the spot and the evaluation depends on subjective feeling. The color mixing process of the colored fibers is a pigment color mixing process and belongs to color space juxtaposition color mixing.
Colors in existing color systems can be scaled by R, G, B values in the color mixing space, so that any color can be represented by a certain vector in the color mixing space. If the color a (R) is to be changeda、Ga、Ba)、b(Rb、Gb、Bb)、b(Rb、Gb、Bb)、d(Rd、Gd、Bd) Color blending can obtain color value m (R) of a blended color samplem、Gm、Bm) Then the color value R of the mixed color samplem=Ra+Rb+Rc+Rd、Gm=Ga+Gb+Gc+Gd、Bm=Ba+Bb+Bc+BdThis corresponds to an operation of summing up vectors in a color mixture space. Since the color and the color mixture can be expressed digitally, the color mixture process of the colored fiber can also be expressed digitally. Based on the above analysis, we consider that the following problems mainly exist in the conventional color matching method:
1. the color mixing process of the color fibers is a pigment color mixing process, a digital physical model is not established in the traditional color mixing method to express the color mixing process of the color fibers, and the physical model needs to be established and the color mixing process of the color fibers needs to be digitally expressed;
2. the color mixing process of the color fiber is to select several color fibers as basic colors and obtain a series of chromatograms by changing the blending ratio. In the traditional color matching method, a mixed color sample is manufactured by hand proofing, a digital method for solving the color value of a mixed color body based on a base color value and mixed color proportion change is not established, a color fiber discrete mixed color model and a visualization algorithm of a mixed color chromatogram thereof need to be established, and digital virtual color matching of color yarns is realized;
3. the series chromatogram can be obtained by the color matching process of the colored fiber. The traditional color matching method adopts manual sampling to obtain color matching chromatograms, and is low in efficiency, long in time consumption and inconvenient for remote transmission. A standard color mixing chromatogram formed by combining and mixing eight primary colors of red, green, blue, cyan, blue, magenta, black, white and the like is required to be constructed, and a reference basis is provided for color matching of the colored yarns;
