A method for constructing the primary color system of colored spinning yarn

Abstract

The invention discloses a method for constructing the primary color system of the color spinning yarn, which includes: obtaining the color data of the color gamut boundary of the color spinning; filling K points in the color gamut to discretize the color gamut space; selecting from the color gamut space filled with color points A subset composed of k primary colors, the primary color data in this subset should meet the MAXMINC method principle; use the triangulation algorithm to determine the number of tetrahedrons generated by k primary color points, and calculate the average value of the tetrahedron vertex color difference; when The average value of the color difference is close to the maximum primary color difference threshold for generating plain colors, and the corresponding number of primary color points is determined as the final number of primary colors. If the conditions are not met, the screening of primary color points and the calculation of the average value of tetrahedral color difference are performed cyclically; according to the visual perception characteristics The color data of the primary color system is arranged; the proofing preparation of the solid color samples is carried out and bound into a book, and the construction of the primary color system of the melange yarn is completed. This method can realize small inventory, scientific color matching, efficient development and digital management in the color spinning industry.

technical field [0001] The invention belongs to the technical field of textile industrial production and application, and in particular relates to a method for constructing a primary color system of color spinning yarn. Background technique [0002] In the field of textile industry production, colored yarn is loved by consumers because of its unique color and style, and is widely used in various textiles such as needles and wovens. color standard. Moreover, it has always been the pursuit of color spinning enterprises to achieve colorful yarns with a minimum amount of basic colors. Some colored fibers are no longer used after one or two use, 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.

Problems solved by technology

[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
