Colored spun yarn primary color system construction method

Abstract

The invention discloses a colored spun yarn primary color system construction method. The method comprises the steps of obtaining color spinning color gamut boundary color data; filling K points in a color gamut to discretize a color gamut space; selecting a subset composed of k primary colors from the color gamut space filled with the color points, wherein primary color data in the subset should meet the principle of the MAXMINC method; determining the number of tetrahedrons generated by k primary color points by adopting a triangulation algorithm, and calculating an average value of color differences of vertexes of the tetrahedrons; when the average value of the chromatic aberration is close to the maximum primary color chromatic aberration threshold value for generating the prime color, determining the number of the corresponding primary color points as the final primary color number; if the condition is not met, screening of the primary color points and calculation of the tetrahedron chromatic aberration average value are circularly executed; arranging color data of the primary color system according to visual perception characteristics; and performing proofing preparation and bookbinding of entity color samples to complete construction of the colored spun yarn primary color system. According to the method, small stock, scientific color matching, efficient development and digital management in the color spinning industry can be realized.

Description

technical field [0001] The invention belongs to the technical field of textile industry production and application, and in particular relates to a method for constructing a primary color system of a colored spinning yarn. Background technique [0002] In the field of textile industry production, colored spun yarn is deeply loved by consumers because of its unique color and style, and is widely used in various types of textiles such as needles and wovens; however, so far, no one has recognized the coloring products for fiber mixing. color standard. Moreover, it has always been the pursuit of colored spinning enterprises to realize rich-colored yarns with the least amount of basic colors. Some colored fibers are no longer used after one or two uses, which will lead to an increasing inventory. Not only will it take up a lot of money, but it will also affect the efficiency of production and operation. Therefore, it is necessary to establish a scientific fiber primary color syst...

[0002] In the field of textile industry production, colored spun yarn is deeply loved by consumers because of its unique color and style, and is widely used in various types of textiles such as needles and wovens; however, so far, no one has recognized the coloring products for fiber mixing. color standard

Moreover, it has always been the pursuit of colored spinning enterprises to realize rich-colored yarns with the least amount of basic colors. Some colored fibers are no longer used after one or two uses, which will lead to an increasing inventory. It not only takes up a lot of money but also affects the efficiency of production and operation, so it is necessary to establish a scientific fiber primary color system

[0003] At this stage, in the field of textile and clothing, those enterprises that have not established the primary color system of fibers mostly use the Munsell color system and the NCS color system, but they are all color perception systems based on visual experiments. Although such color cards are convenient to search and Color selection, but it does not involve how to realize the color on textiles, and there is basically no guiding significance for the development of interlocking products with large color differences in fiber dyeing.

In addition, those large-scale enterprises use their own accumulated color standards and corresponding standard books, such as Blum color cards, Huafu color cards, etc. The arrangement and habits of these color cards are not consistent. It is inconvenient to find during use, and their color gamut is smaller than the Munsell color system and NCS color system

The absence and defects of color cards lead to the inability of enterprises to meet the diverse and individual needs of users. In terms of color use, production and control, the production efficiency is greatly reduced, resulting in limitations in color matching and color development, which limits the enterprise's own development. develop

[0004] At present, most of the existing color spinning enterprises mainly carry out commercial delivery through physical color cards, yarn samples, cloth samples and other media, which will consume a lot of time and money, and affect the cost of color production and management of color spinning enterprises and efficiency; some enterprises still have many problems such as no corresponding color formula reference in the color matching process, difficulty in finding physical color information, resulting in inability to effectively develop new colors, and even ignore the color that has been produced and directly carry out color development again. Therefore, It is urgent to establish a scientific fiber primary color system
