The present disclosure relates to a color control method for four-color field jet dyeing, a color control device for four-color field jet dyeing, and a color control system for four-color field jet dyeing.
Textile dyeing is a technology that uses dyes to dye and process a material to be dyed. Traditional textile dyeing, in addition to special dyeing technologies such as discharge dyeing and wax dyeing, is mostly based on the color of the dye to prepare spot color ink for dyeing. In practical use of this technology, the use of spot color dyeing requires comprehensive cleaning of an ink supply system in equipment for each product order, which is time-consuming, laborious and not environment-friendly. Therefore, a four-color field jet dyeing system similar to that used in the printing industry can be used, where the four-color field jet dyeing system combines four-color and field jet dyeing technologies. However, at present, there is an urgent need to develop a color control method for four-color field jet dyeing, as well as a corresponding color control device and color control system.
The present disclosure aims to provide a color control method for four-color field jet dyeing, a color control device for four-color field jet dyeing, and a color control system for four-color field jet dyeing. The color control of four-color field jet dyeing can be achieved by virtue of the method, the color control device and the color control system.
A first aspect of the present disclosure relates to a color control method for four-color field jet dyeing. The method includes: obtaining fabric parameters of a fabric to be dyed; obtaining a fabric sample color; ascertaining whether predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color exist in a field jet dyeing database; if not, generating temporary pre-color-development color parameters based on the fabric parameters and the fabric sample color, taking the temporary pre-color-development color parameters as contrast sample parameters, and generating field jet dyeing parameters according to the contrast sample parameters to dye the fabric; and if yes, taking the predetermined pre-color-development color parameters in the field jet dyeing database as the contrast sample parameters, and generating the field jet dyeing parameters according to the contrast sample parameters to dye the fabric. Therefore, for two cases that the predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color exist and do not exist in the field jet dyeing database, the present disclosure proposes corresponding solutions to meet the requirements of different cases. In the present disclosure, the four-color includes three primary colors and black, where the three primary colors refer to cyan, magenta and yellow respectively, and the three primary colors and the black are together referred to as CMYK.
In some embodiments, after the fabric parameters of the fabric to be dyed are obtained, whether the fabric parameters corresponding to the fabric to be dyed already exist in the field jet dyeing database can be ascertained; and if not, establishing the fabric parameters corresponding to the fabric to be dyed in the field jet dyeing database.
In some embodiments, when the fabric is dyed through the field jet dyeing parameters, a first four-color field jet dyeing device can be enabled to dye the fabric according to the field jet dyeing parameters, a first fabric color is detected after color fixing, and the first fabric color is compared with the contrast sample parameters to obtain a first fabric color deviation, where if the first fabric color deviation is less than or equal to a color deviation threshold, a color development process is performed directly; and if the first fabric color deviation is greater than the color deviation threshold, the field jet dyeing parameters are readjusted, and the first four-color field jet dyeing device and/or a second four-color field jet dyeing device arranged at a downstream side of the first four-color field jet dyeing device is enabled to perform online adjustment of dyeing according to the adjusted field jet dyeing parameters until the first fabric color deviation is less than or equal to the color deviation threshold. Therefore, the advantages of four-color field jet dyeing can be fully used, that is, a four-color nozzle can be directly used for field jet dyeing without changing an ink system, and controlled online adjustment of dyeing can be achieved by online real-time monitoring of the fabric color and real-time adjustment of the dyeing parameters according to the color deviation.
In some embodiments, the adjusted field jet dyeing parameters for the first four-color field jet dyeing device and/or the second four-color field jet dyeing device can be provided according to the first fabric color deviation and a current dye concentration.
In some embodiments, if it is ascertained that the predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color do not exist in the field jet dyeing database, after color development of the fabric, a second fabric color after color development can be detected, and the second fabric color is compared with the fabric sample color to obtain a second fabric color deviation, where if the second fabric color deviation is less than or equal to the color deviation threshold, batch production is performed based on the field jet dyeing parameters used in a dyeing process before the color development process; and if the second fabric color deviation is greater than the color deviation threshold, the contrast sample parameters and the field jet dyeing parameters are readjusted, and the dyeing and color development are performed again until the second fabric color deviation is less than or equal to the color deviation threshold. Therefore, for the case that the predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color do not exist in the field jet dyeing database, the present disclosure proposes corresponding solutions for different cases after color development, and especially for the case that the color deviation requirement is met during dyeing but there is an unacceptable color deviation after color development.
In some embodiments, the adjusted contrast sample parameters and field jet dyeing parameters can be provided according to the second fabric color deviation.
In some embodiments, the temporary pre-color-development color parameters can be computed and simulated by a field jet dyeing database model.
In some embodiments, the fabric sample color can be detected by a first color detection device to obtain the fabric sample color.
In some embodiments, the first fabric color can be detected by a second color detection device.
In some embodiments, the second fabric color can be detected by the first color detection device.
In some embodiments, if it is ascertained that the fabric parameters corresponding to the fabric to be dyed do not exist in the field jet dyeing database, monogenetic dyes with different concentrations in three three-primary color dyes and one black dye can be used for performing field jet dyeing on the fabric and performing color development on a textile, where color parameters before color development of the fabric are detected by the second color detection device, color parameters after color development of the fabric are detected by the first color detection device, and a new field jet dyeing database for the fabric is generated by the field jet dyeing database model based on the color parameters before color development of the fabric and the color parameters after color development of the fabric. Therefore, for the case that the fabric parameters corresponding to the fabric to be dyed do not exist in the field jet dyeing database, the present disclosure proposes a corresponding solution. Here, the three-primary color dyes include a cyan dye, a magenta dye and a yellow dye.
In some embodiments, the field jet dyeing parameters can be generated according to the contrast sample parameters and inputted running speed.

The present disclosure is further described below with reference to the schematic accompanying drawings by exemplary implementations, where
In the embodiment shown in
The color control system 100 further includes four four-color field jet dyeing devices 110, and the four-color field jet dyeing devices 110 are configured to use three three-primary color dyes and one black dye to perform four-color field jet dyeing. The four four-color field jet dyeing devices 110 can be respectively arranged on two sides of the fabric, so that double-sided dyeing of the fabric 1 can be achieved, or single-sided dyeing can be achieved by only using two of the single-sided four-color field jet dyeing devices 110. In some embodiments, the four-color field jet dyeing devices 110 can also be only arranged on one side of the fabric 1, thus achieving single-sided dyeing. The four-color field jet dyeing devices 110 are configured to use three three-primary color dyes and one black dye to perform four-color field jet dyeing. In this embodiment, each four-color field jet dyeing device 110 is respectively constructed as a four-color nozzle for four-color field jet dyeing.
In this embodiment, the four-color nozzle has four dyeing nozzles, and the four dyeing nozzles are respectively configured to eject dyes with one of three primary colors and black by virtue of field jet. Of course, the present disclosure is not limited to this. Any other number of dyeing nozzles can be arranged. Similarly, any other number of four-color field jet dyeing devices 110 can also be arranged. For example, only one or more than two four-color field jet dyeing devices 110 can be arranged on the same side. When two or more four-color field jet dyeing devices 110 are arranged on the same side, the four-color field jet dyeing device 110 arranged at a downstream side can achieve color complement, where the color complement can be achieved by four-color field jet dyeing parameters adjusted based on online color detection, thus achieving online adjustment of dyeing. Of course, in a case that only one four-color field jet dyeing device 110 is arranged on the same side, online adjustment of dyeing can also be achieved, where the four-color field jet dyeing device 110 can adjust its own four-color field jet dyeing parameters in real time according to the downstream online color detection, that is, the advantages of four-color dyeing are fully used, and a color deviation from the contrast sample parameters is reduced by the change of its own four-color field jet dyeing parameters.
As shown in
In order to detect the color of the dyed fabric, the color control system 100 includes a second color detection device 130 arranged at the downstream side of the corresponding four-color field jet dyeing device 110 in the movement direction of the fabric 1. In the embodiment, the second color detection device 130 is also arranged at a downstream side of the heating device 140, so as to detect a first fabric color after color fixing. The first fabric color is a fabric color after dyeing and before color development. After color development of the fabric, a second fabric color is formed on the fabric. The second fabric color can be detected by the first color detection device 120. In some embodiments, the second fabric color can be detected by another color detection device different from the first color detection device 120 and the second color detection device 130.
In order to perform color control of four-color field jet dyeing, the color control system 100 further includes a color control device 150 for color control and a storage device matched with the color control device 150. A field jet dyeing database can be stored in the storage device. The color control device 150 can be in communication connection with the four-color field jet dyeing device 110 to control the four-color field jet dyeing device 110. The color control device 150 can also be in communication connection with the first color detection device 120 and the second color detection device 130 to receive detection data from the first color detection device 120 and the second color detection device 130. The color control device 150 can also be in communication connection with the storage device to call data from the storage device or store data in the storage device. By connecting the color control device 150 with the four-color field jet dyeing device 110, the first color detection device 120 and the second color detection device 130, online control or online adjustment of dyeing of the four-color field jet dyeing device 110 can be achieved. Therefore, the first fabric color detected by the second color detection device 130 can be inputted to the color control device 150, and then, the color control device 150 can compare the first fabric color with the contrast sample parameters generated based on the fabric sample color obtained by the first color detection device 120 to obtain a first fabric color deviation, where if the first fabric color deviation is less than or equal to a color deviation threshold, a color development process is performed directly; and if the first fabric color deviation is greater than the color deviation threshold, the field jet dyeing parameters are readjusted, and the corresponding four-color field jet dyeing device 110 is enabled to perform online adjustment of dyeing according to the adjusted field jet dyeing parameters until the first fabric color deviation is less than or equal to the color deviation threshold. In addition, for the case that the predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color do not exist in the field jet dyeing database, after color development of the fabric, the second fabric color after color development, detected by the first color detection device 120, can be inputted to the color control device 150, and then, the color control device 150 can compare the second fabric color with the fabric sample color to obtain a second fabric color deviation, where if the second fabric color deviation is less than or equal to the color deviation threshold, batch production is performed based on the field jet dyeing parameters used in a dyeing process before the color development process; and if the second fabric color deviation is greater than the color deviation threshold, the contrast sample parameters and the field jet dyeing parameters are readjusted, and the dyeing and color development are performed again until the second fabric color deviation is less than or equal to the color deviation threshold.
The color control device 150 and the storage device can be integrally constructed. In some embodiments, the color control device 150 and the storage device can be integrated. In some embodiments, the color control device 150 and the storage device can also be separated.
As shown in

In addition, the integrating spheres 230 and 330 can be constructed as d/8 degree integrating spheres. A side wall of each of the integrating spheres 230 and 330 is provided with an entrance port, and light emitted by the light source enters the integrating spheres 230 and 330 through the corresponding entrance port. The fabric 1 is located at lower openings of the integrating spheres 230 and 330. The color sensor 210 and the optical fiber head 360 are arranged at a −8° position perpendicular to a normal of the fabric 1 on the corresponding integrating spheres 230 and 330. The light traps 240 and 340 can be arranged at a +8° position perpendicular to the normal of the fabric 1 on the corresponding integrating spheres 230 and 330.

A color control method for four-color field jet dyeing according to an embodiment of the present disclosure is described below with reference to
In the method, first, fabric parameters of the fabric 1 to be dyed are obtained, for example, the fabric parameters are inputted to the color control system 100. After the fabric parameters of the fabric 1 to be dyed are obtained, whether the fabric parameters corresponding to the fabric 1 to be dyed already exist in the field jet dyeing database can be ascertained; if yes, the next step is performed directly; and if not, the fabric parameters corresponding to the fabric 1 to be dyed are established in the field jet dyeing database.
Then, the color of the fabric sample 2 is obtained, for example, the fabric sample color is obtained by the first color detection device 120. After the fabric sample color is obtained, whether predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color exist in the field jet dyeing database can be ascertained; if yes, the predetermined pre-color-development color parameters in the field jet dyeing database are taken as contrast sample parameters, and field jet dyeing parameters are generated according to the contrast sample parameters to dye the fabric; and if not, temporary pre-color-development color parameters are generated based on the fabric parameters and the fabric sample color, the temporary pre-color-development color parameters are taken as the contrast sample parameters, and the field jet dyeing parameters are generated according to the contrast sample parameters to dye the fabric. Here, the field jet dyeing parameters are generated according to the contrast sample parameters and inputted running speed. The temporary pre-color-development color parameters are computed and simulated by a field jet dyeing database model.
Then, when the fabric is dyed through the field jet dyeing parameters, a first four-color field jet dyeing device is enabled to dye the fabric according to the field jet dyeing parameters, a first fabric color is detected by the second color detection device 130 after color fixing, and the first fabric color is compared with the contrast sample parameters to obtain a first fabric color deviation, where if the first fabric color deviation is less than or equal to a color deviation threshold, a color development process is performed directly; and if the first fabric color deviation is greater than the color deviation threshold, the field jet dyeing parameters are readjusted, and the first four-color field jet dyeing device and/or a second four-color field jet dyeing device arranged at a downstream side of the first four-color field jet dyeing device is enabled to perform online adjustment of dyeing according to the adjusted field jet dyeing parameters until the first fabric color deviation is less than or equal to the color deviation threshold. As mentioned above, the online adjustment of dyeing can be completed together by the first four-color field jet dyeing device and the second four-color field jet dyeing device, that is, the second four-color field jet dyeing device is used for color complement; and the online adjustment of dyeing can also be completed by the first four-color field jet dyeing device, that is, the field jet dyeing parameters of the first four-color field jet dyeing device are adjusted in real time according to the downstream color deviation detection result. Here, the adjusted field jet dyeing parameters for the first four-color field jet dyeing device and/or the second four-color field jet dyeing device are provided according to the first fabric color deviation and a current dye concentration.
If it is ascertained that the predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color do not exist in the field jet dyeing database, after color development of the fabric, a second fabric color after color development is detected by the first color detection device 120, and the second fabric color is compared with the fabric sample color to obtain a second fabric color deviation, where if the second fabric color deviation is less than or equal to the color deviation threshold, batch production (also known as “bulk production”) is performed based on the field jet dyeing parameters used in a dyeing process before the color development process; and if the second fabric color deviation is greater than the color deviation threshold, the contrast sample parameters and the field jet dyeing parameters are readjusted, and the dyeing and color development are performed again until the second fabric color deviation is less than or equal to the color deviation threshold. Here, the adjusted contrast sample parameters and field jet dyeing parameters are provided according to the second fabric color deviation. In addition, if it is ascertained that the predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color exist in the field jet dyeing database, after the dyeing meeting requirements and the subsequent color development are completed, it is not necessary to detect the second fabric color after color development, and the batch production is performed directly.
If it is ascertained that the fabric parameters corresponding to the fabric 1 to be dyed do not exist in the field jet dyeing database, monogenetic dyes with different concentrations in three three-primary color dyes and one black dye are used for performing field jet dyeing on the fabric and performing color development on a textile, where color parameters before color development of the fabric are detected by the second color detection device 130, color parameters after color development of the fabric are detected by the first color detection device 120, and a new field jet dyeing database for the fabric 1 is generated by the field jet dyeing database model based on the color parameters before color development of the fabric and the color parameters after color development of the fabric.
In the present disclosure, the color deviation threshold ΔE may be 0.5. Of course, other values may also be considered.
The present disclosure is further described below with non-restrictive embodiments. However, it should be noted that these embodiments should not be considered as limitations to the present disclosure.
Because the specifications of the fabric 1 (including yarn specifications, density, fabric texture and the like of the fabric 1) may affect the final color presentation during dyeing, in a specific implementation process, a corresponding field jet dyeing database is established based on the fabric 1. Therefore, the sample processing mainly involves two cases: (1) a field jet dyeing database with the fabric 1, and (2) a field jet dyeing database without the fabric 1.
The case with a field jet dyeing database may also be divided into: (1-1) a fabric sample color has been made, and (1-2) no fabric sample color has been made.
For the case that a color control system 100 for four-color field jet dyeing has already made a fabric sample color for this machine and a field jet dyeing database has already stored parameters of a fabric 1, a first color control process includes:
For the case that a color control system 100 for four-color field jet dyeing does not make a fabric sample color for this machine and a field jet dyeing database has already stored parameters of the fabric 1, a second color control process includes:
For the case that a color control system 100 for four-color field jet dyeing does not store data of the fabric to be dyed of a fabric sample color in a field jet dyeing database, a third color control process includes:
