Abstract

[Problem] To provide a color control system for four-color field jet dyeing. [Solution] The system searches for whether there are pre-color parameters corresponding to the fabric parameters and the color of the sample fabric. If there are no pre-color parameters, it generates temporary pre-color parameters based on the fabric parameters and the color of the sample fabric, and uses these temporary pre-color parameters as reference sample parameters. These reference sample parameters generate field jet dyeing parameters, and the fabric is dyed. If there are pre-color parameters, the system uses the pre-color parameters in the field jet dyeing database as reference sample parameters, and generates field jet dyeing parameters based on these reference sample parameters, and the fabric is dyed.

Description

This invention relates to a color control system for four-color field jet dyeing. Textile dyeing is the technique of dyeing materials using dyes. In traditional textile dyeing, with the exception of special dyeing techniques such as discharge dyeing and batik, most dyeing is done using special inks prepared according to the desired color. This is a schematic diagram of a color control system based on an embodiment of the present invention.This is a schematic diagram of an integrated first color detection device and/or second color detection device in a color control system based on an embodiment of the present invention.This is a schematic diagram of a split-type first color detection device and/or second color detection device in a color control system based on an embodiment of the present invention.This is a flowchart of a color control method for four-color field jet staining based on an embodiment of the present invention. Here, the technical features described above, the technical features described below, and the technical features shown in the drawings can be combined in any way, as long as they do not contradict each other. All technically feasible combinations of functions are included in the technical content described in the specification. The present invention will be described in more detail below, with reference to schematic diagrams and exemplary embodiments. Figure 1 is a schematic diagram of a color control system 100 based on an embodiment of the present invention. In the embodiment shown in Figure 1, the color control system 100 includes a first color detection device 120, which performs detection on a sample fabric. The first color detection device 120 may also be configured to detect the color of the fabric after color development. To better detect the color of the sample fabric 2, the first color detection device 120 can be positioned above the sample fabric stand. By examining the color of the obtained sample fabric and the fabric parameters of dyed fabric 1, it is possible to determine whether the planned pre-color parameters corresponding to the fabric parameters and the color of the sample fabric exist in the field jet dyeing database. Based on this, temporary pre-color parameters are generated or planned pre-color parameters are obtained. In this way, the corresponding contrast sample parameters are determined and used as a criterion for judging the degree of color deviation during dyeing. The color control system 100 further includes four four-color field jet dyeing apparatuses 110. Each four-color field jet dyeing apparatus 110 is configured for four-color field jet dyeing using three primary dyes and one black dye. The four four-color field jet dyeing devices 110 can be installed on both sides of the fabric. In this way, both sides of the fabric 1 can be dyed, or single-sided dyeing can be achieved by using only two of the four-color field jet dyeing devices 110 on one side. In some embodiments, to achieve single-sided dyeing, the four-color field jet dyeing apparatus 110 can be installed on only one side of the dyed fabric 1. The four-color field jet dyeing apparatus 110 is configured for four-color field jet dyeing using three primary color dyes and one black dye. In this embodiment, each of the four-color field jet dyeing apparatus 110 is configured as a four-color nozzle for four-color field jet dyeing. In this embodiment, the four-color nozzle has four dyeing nozzles, each designed to spray a dye of one of the three primary colors and black via a field jet. Of course, the present invention is not limited to this, and it is possible to provide other numbers of dyeing nozzles. Similarly, any other number of four-color field jet staining devices 110 can be provided. For example, only one four-color field jet staining device 110 can be provided on the same side, or two or more four-color field jet staining devices 110 can be provided. When two or more four-color field jet staining devices 110 are installed on the same side, the downstream four-color field jet staining device 110 can achieve complementary colors. Here, complementary colors can be achieved by adjusting the four-color field jet staining parameters based on online color detection, thereby enabling online adjusted staining. Of course, even if only one four-color field jet staining device 110 is installed on the same side, online adjustment staining can be performed. The four-color field jet staining device 110 can adjust its own four-color field jet staining parameters in real time based on downstream online color detection. Therefore, it is possible to maximize the advantages of four-color staining and reduce color deviation (color discrepancy) with the parameters of the comparison sample by changing the parameters unique to four-color field jet staining. As shown in Figure 1, the color control system 100 also includes a heating device 140 positioned downstream of the four-color field jet dyeing apparatus 110 alon
