Description

Technical Field

[0001] The present invention relates to a method for obtaining a production color addition formula, and in particular to an intelligent production color addition method and system. Background Art

[0002] Printing and dyeing production and processing is an extremely critical link in the textile industry chain. It can transform originally monotonous fabrics into colorful ones, and provide rich and diverse basic materials for subsequent clothing manufacturing, home textile and other industries, thereby significantly improving the aesthetics of the products, meeting the increasingly diverse aesthetic needs of consumers, and thus enhancing the company's market competitiveness and brand appeal.

[0003] In the daily production processes of printing and dyeing companies, after the dyeing process is completed, samples are usually taken for color comparison with a standard sample. If the color difference is within an acceptable range, the dyeing process can be completed and the product can smoothly enter the subsequent production process. This situation is called a successful first-time dyeing production. However, if the color difference exceeds the acceptable range, the fabric needs to be color corrected. Depending on the specific color correction, there are two main methods of correction: one is to add dye and dye again, which is called "additional coloring"; the other is to first strip the color from the fabric and then "add coloring" again until the color difference is within the acceptable range. In actual production, due to the combined influence of many factors such as equipment stability, process execution precision, raw material quality stability, operator experience and skills, etc., the probability of successful first-time dyeing production is not high, so the need for additional coloring is relatively common.

[0004] Furthermore, while both color addition in production and color correction during the laboratory sampling process involve color correction, there are significant differences between the two. First, color addition in production is performed on fabrics with existing colors, while color correction during the laboratory sampling process is based on the color correction formula and re-dyed using a blank substrate. Second, color addition in production can only be increased or maintained based on the initial formula, and the increased part is the corresponding color addition formula, while color correction during the laboratory sampling process can be increased, decreased, or maintained based on the initial formula. Finally, the weight of fabric processed in production is typically tens or even thousands of kilograms, so the number of color additions should not be too many. Otherwise, it will not only extend the production cycle but also damage the fabric, consume a lot of manpower and material resources, significantly increase production costs, and the trial and error costs are extremely high. In contrast, the weight of fabric processed during the laboratory sampling process is generally only a few grams to tens of grams, allowing for multiple color corrections, and the trial and error costs are relatively low.

[0005] For this reason, research on computer-aided color correction methods for laboratories began early and has been widely used in industry. However, in stark contrast, research on production color addition is relatively limited. Currently, most companies still rely primarily on experienced technicians to manually add color to production, a method that is highly subjective and difficult to guarantee accuracy and stability. To minimize the situation of "over-adding color, then stripping and adding color again," most companies adopt a "small amount, multiple times" color addition method. This undoubtedly increases the number of color additions, thereby reducing production efficiency and further increasing production costs.

[0006] Digitalization and automation technologies are beginning to be widely applied across various industries. Against this backdrop, developing an intelligent color addition method and system that is simple to operate, stable, objective, and accurate to improve production efficiency and reduce production costs has become an inevitable trend in the future development of the printing and dyeing industry, and holds extremely broad market prospects.
