[Diagram 3] 1 is a flow chart of a color control method for four-color field jet dyeing according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Here, the above-mentioned technical features, the technical features described below, and the technical features shown in the drawings may be arbitrarily combined as long as they are not mutually contradictory. All technically feasible combinations of functions are included in the technical content described in the specification.

[0024] The invention will now be described in more detail with reference to exemplary embodiments with reference to schematic diagrams: Figure 1 is a schematic diagram of a color control system 100 according to an embodiment of the invention.

[0025] In the embodiment shown in Figure 1, the color control system 100 includes a first color detection device 120 that performs detection on a sample fabric and may be configured to detect the color of the fabric after color development.

[0026] In order to better detect the color of the sample cloth 2, the first color detection device 120 can be disposed above the sample cloth platform.

[0027] Through the obtained sample fabric color and the fabric parameters of the dyed fabric 1, it can be determined whether the planned pre-coloring color parameters corresponding to the fabric parameters and the color of the sample fabric exist in the field jet dyeing database, and based on this, temporary pre-coloring color parameters are generated or the planned pre-coloring color parameters are obtained, and thus the corresponding comparison sample parameters are determined as the basis for judging the degree of color deviation during dyeing.

[0028] The color control system 100 further includes four four-color field jet dyers 110. The four-color field jet dyers 110 are configured for four-color field jet dyeing using three primary color dyes and one black dye.

[0029] The four four-color field jet dyeing devices 110 can be installed on both sides of the fabric, respectively. In this way, two-sided dyeing of the dyed fabric 1 can be achieved, or one-sided dyeing can be achieved by using only two of the four-color field jet dyeing devices 110 on one side.

[0030] In some embodiments, the four-color field jet dyeing apparatus 110 may be provided on only one side of the dyed fabric 1 to achieve single-sided dyeing.

[0031] The four-color field jet dyeing devices 110 are 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 devices 110 is configured as a four-color nozzle for four-color field jet dyeing.

[0032] In this embodiment, the four-color nozzle has four dye nozzles, each of which is designed to jet dye of one color among the three primary colors and black by a field jet, although the present invention is not limited thereto and other numbers of dye nozzles may be provided.

[0033] Similarly, any other number of four-color field jet dyers 110 may be provided, for example, only one four-color field jet dyer 110 on the same side, or two or more four-color field jet dyers 110 may be provided.

[0034] When two or more four-color field jet dyeing devices 110 are installed on the same side, the downstream four-color field jet dyeing device 110 can realize complementary colors, where the complementary colors can be realized by adjusting the four-color field jet dyeing parameters based on online color detection, thereby realizing online adjusted dyeing.

[0035] Of course, even if only one four-color field jet staining apparatus 110 is installed on the same side, online adjusted staining can be performed, and the four-color field jet staining apparatus 110 can adjust its own four-color field jet staining parameters in real time based on downstream online color detection, so that the advantages of four-color staining can be maximized and the color deviation (color shift) from the parameters of the comparison sample can be reduced by changing the unique parameters of the four-color field jet staining.

[0036] 1, the color control system 100 also includes a heating device 140 disposed downstream of the four-color field jet dyeing device 110 along the direction of travel of the dyed fabric 1. The heating device 140 is configured to heat the dyed fabric to fix the color in the fabric.

[0037] In this embodiment, the heating device 140 is configured as an oven, which can use thermal radiation to heat the dyes to fix the color, while in other embodiments, the heating device 140 can be configured as a hot air heater, which can use hot air to heat the dyes to achieve color fixation.

[0038] To detect the color of the fabric after it has been dyed, the color control system 100 includes a second color detection device 130 disposed downstream of the corresponding four-color field jet dyeing device 110 in the traveling direction of the dyed fabric 1 .

[0039] In this embodiment, a second color detection device 130 is also disposed downstream of the heating device 140 to detect a first fabric color after color fixing. The first fabric color is the color of the fabric after dyeing and before color development.

[0040] After coloring the fabric, a second fabric color is formed on the fabric, which can be detected by the first color detection device 120.

[0041] In this embodiment, the second fabric color may be detected by another color detection device different from the first color detection device 120 and the second color detection device 130.

[0042] To perform color control of the four-color field jet dyeing, the color control system 100 further includes a color control device 150 for color control and a storage device compatible with the color control device 150. The field jet dyeing database may be stored in the storage device.

[0043] The color control device 150 can communicate with the four-color field jet dyer 110 and can control the four-color field jet dyer 110 .

[0044] The color control device 150 is in communication with the first color detection device 120 and the second color detection device 130 and can receive detection data from the first color detection device 120 and the second color detection device 130 .

[0045] The color control device 150 may also communicate with a storage device to read data from the storage device and to store data in the storage device.

[0046] Through the connection between the color control device 150, the four-color field jet dyeing device 110, the first color detection device 120 and the second color detection device 130, the four-color field jet dyeing device 110 can be controlled online or can perform online adjustment dyeing.

[0047] Therefore, the first fabric color detected by the second color detection device 130 can be input to the color control device 150. Then, the color control device 150 compares the first fabric color with the contrast sample parameters generated based on the color of the sample fabric obtained through the first color detection device 120 to obtain a first fabric color deviation.

[0048] Here, if the first fabric color deviation is equal to or less than the color deviation threshold value, the process goes directly to the color development step.

[0049] 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 prompted to perform online adjusted dyeing based on the adjusted field jet dyeing parameters until the first fabric color deviation is equal to or less than the color deviation threshold.

[0050] In addition, if there are no fabric parameters or pre-color parameters corresponding to the color of the sample fabric in the field jet dyeing database, after the fabric is colored, the second fabric color after coloring detected by the first color detection device 120 may be input to the color control device 150.

[0051] The color control device 150 can then compare the color of the second fabric with the color of the sample fabric to obtain the color deviation of the second fabric.

[0052] Here, if the color deviation of the second fabric is equal to or less than the color deviation threshold, it is mass-produced based on the field jet dyeing parameters used in the dyeing process before the color development process.

[0053] If the color deviation of the second fabric is greater than the color deviation threshold, the contrast sample parameters and the field jet dyeing parameters are adjusted again, and dyeing and color development are performed again, until the color deviation of the second fabric is equal to or less than the color deviation threshold.

[0054] The color control device 150 may be integrated with a storage device. In some embodiments, the color control device 150 may be integrated with a storage device. In some embodiments, the color control device 150 may be separate from the storage device.

[0055] As shown in Figure 1, in the dyeing production line of the dyed fabric 1, the four-color field jet dyeing device 110, the heating device 140 and the second color detection device 130 can be integrated to form a four-color field dyeing and color detection assembly. In this embodiment, there are a total of four sets (groups) of four-color dyeing and color detection assemblies.

[0056] The four groups of four-color dyeing and color detection assemblies are arranged in pairs on either side of the dyed fabric 1. In other embodiments, there may be two groups, six groups, eight groups, etc. of four-color dyeing and color detection assemblies.

[0057] Briefly, in Figure 1: Devices that correspond to only one in each four-colour staining and colour detection assembly are given reference numbers.

[0058] The structure of the first color detection device 120 and / or the second color detection device 130 according to an embodiment of the present invention will be described in detail below with reference to Figs. 2a and 2b.

[0059] As shown in FIG. 2 a , the first color sensing device 120 and / or the second color sensing device 130 are configured as an integrated color sensing camera head with an integrated color sensor 210 .

[0060] The integrated color-sensing camera head further includes a light source 220, an integrating sphere 230, a light trap 240, and a lens 250. The light trap 240 is disposed at the specular hole of the integrating sphere 230.

[0061] Color sensor 210 is disposed so as to receive light emitted from the light receiving hole of integrating sphere 230 , and lens 250 is disposed between the light receiving hole of integrating sphere 230 and color sensor 210 .

[0062] The color light is received by the color sensor 210, the received color light is corrected by the spectral response curve and the color difference result calculated thereby, and the color difference result is transmitted to the color control device 150 via a communication connection between the output terminal of the color sensor 210 and the input terminal of the color control device 150.

[0063] A plurality of, preferably 16, photodiodes may be integrated onto a single chip of the color sensor 210, where preferably the first four photodiodes of the plurality of photodiodes have red filters.

[0064] Specifically, four second photodiodes of the plurality of photodiodes have green filters, specifically four third photodiodes of the plurality of photodiodes have blue filters, and the remaining photodiodes have no filters.

[0065] As shown in FIG. 2 b , the first color detection device 120 and / or the second color detection device 130 are configured in a split type and include an integrated color detection camera head and spectrometer 310 .

[0066] The integrated color-sensing camera head includes a light source 320, an integrating sphere 330, a light trap 340, a lens 350, and a fiber optic head 360, with a fiber optic connection between the fiber optic head 360 and the spectrometer via a fiber optic 370.

[0067] Light trap 340 is positioned at the specular hole of integrating sphere 330, fiber optic head 360 is positioned to receive light emitted through the receiver hole of integrating sphere 330, and lens 350 is positioned between the receiver hole of integrating sphere 330 and fiber optic head 360.

[0068] The color light may be received by the fiber optic head 360, and the received color light may be transmitted to the spectrometer 310 via the optical fiber 370. Also, the output terminal of the spectrometer 310 is communicatively connected to the input terminal of the color control device 150.

[0069] In the two different configurations of the first color detection device 120 and / or the second color detection device 130, the light source 220, 320 may be configured as a coaxial light source with an LED array.

[0070] The light sources 220 and 320 can be selected from a group including A standard light source, C standard light source, and D series standard light sources D50, D65, D75, and F standard light source conforming to the CIE standard.

[0071] The color temperature of the standard light source is 2500K to 3000K, preferably 2856K. The color temperature of the C standard light source is 6500K to 7000K, preferably 6774K. The color temperature of the D series standard light source is 4500K to 8000K, preferably 5000K to 7500K. The color temperature of the F standard light source is 2500K to 3000K, preferably 2700K.

[0072] Furthermore, the integrating sphere 230, 330 can be configured as a d / 8 degree integrating sphere. An entrance is provided on the side wall of the integrating sphere 230, 330, and the light emitted from the light source enters the integrating sphere 230, 330 through the entrance. The dyed fabric 1 is located at the lower opening of the integrating sphere 230, 330.

[0073] The color sensor 210 and fiber optic head 360 are positioned at −8° of the normal to the dyed fabric 1 on the corresponding integrating sphere 230, 330. The light trap 240, 340 may be positioned at +8° of the normal to the dyed fabric 1 on the corresponding integrating sphere 230, 330.

[0074] The field jet dyeing parameters include at least one of the following parameters: concentration of dye ejected from each four-color field jet dyer 110, amount of dye sprayed by each four-color field jet dyer 110, spray working distance of each four-color field jet dyer 110, gas field parameters of each four-color field jet dyer 110, and electric field parameters of each four-color field jet dyer 110.

[0075] Hereinafter, a color control method for four-color field jet dyeing according to an embodiment of the present invention will be described with reference to FIG.

[0076] In this method, first, the fabric parameters of the dyed fabric 1 are obtained, for example, the fabric parameters are input into the color control system 100 .

[0077] After obtaining the fabric parameters of the dyed fabric 1, it is checked whether the fabric parameters corresponding to the dyed fabric 1 to be dyed already exist in the field jet dyeing database, and if they exist and the answer is "yes", proceed directly to the next step, and if they do not exist and the answer is "no", the fabric parameters corresponding to the dyed fabric 1 are provided in the field jet dyeing database.

[0078] Then, the color of the sample cloth 2 is obtained, for example, by the first color detection device 120. After obtaining the color of the sample cloth, it is checked whether there are any pre-coloring color parameters corresponding to the fabric parameters and the color of the sample cloth in the field jet dyeing database.

[0079] If yes, use the pre-color parameters in the field jet dye database as the comparison sample parameters, generate field jet dye parameters based on the comparison sample parameters, and dye the fabric.

[0080] Otherwise, if the answer is "No", generate temporary pre-coloring parameters based on the fabric parameters and the color of the sample fabric, and use the temporary pre-coloring parameters as the contrast sample parameters. Generate field jet dyeing parameters based on the contrast sample parameters for dyeing the fabric, where the field jet dyeing parameters are generated based on the contrast sample parameters and the input vehicle speed.

[0081] The extra color pre-development parameters are calculated and simulated through a field jet dye database model.

[0082] Next, when dyeing the fabric using the field jet dyeing parameters, the first four-color field jet dyeing device is prompted to dye the fabric based on the field jet dyeing parameters, and after the color is fixed, the first fabric color is detected by the second color detection device 130, and the first fabric color is compared with the contrast sample parameters to obtain the deviation of the first fabric color.

[0083] Here, if the first fabric color deviation is equal to or less than the color deviation threshold value, the process goes directly to the color development step.

[0084] If the first fabric color deviation is greater than the color deviation threshold, the field jet dyeing parameters are adjusted again, and based on the adjusted field jet, the first four-color field jet dyeing device itself and / or a second four-color field jet dyeing device arranged downstream of the first four-color field jet dyeing device are prompted to perform online adjustment dyeing until the first fabric color deviation is equal to or less than the color deviation threshold.

[0085] As mentioned above, the first four-color field jet dyeing device and the second four-color field jet dyeing device can complete the online adjusted dyeing, and the second four-color field jet dyeing device can be used to complement the color, or the first four-color field jet dyeing device itself can be used to complete the color complementation.

[0086] That is, the field jet dyeing parameters of the first four-color field jet dyeing device itself are adjusted in real time based on the detection result of the downstream color deviation, where 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 based on the first fabric color deviation and the current dye concentration.

[0087] If it is found that the pre-coloring color parameters corresponding to the fabric parameters and the color of the sample do not exist in the field jet dyeing database, after the fabric is colored, the color of the second fabric after coloring is also detected via the first color detection device 120, and the color of the second fabric is compared with the color of the sample fabric to obtain the color deviation of the second fabric.

[0088] Among these, when the color deviation of the second fabric is equal to or less than the color deviation threshold, mass production (also called "mass production") is carried out based on the field jet dyeing parameters used in the dyeing process before the color development process.

[0089] If the color deviation of the second fabric is greater than the color deviation threshold, the contrast sample parameters and the field jet dyeing parameters are adjusted again, and dyeing and color development are performed again until the color deviation of the second fabric is equal to or less than the color deviation threshold.

[0090] Here, based on the color deviation of the second fabric, adjusted contrast sample parameters and field jet dyeing parameters are given.

[0091] Also, if it is found that the field jet dye database contains pre-planned color parameters corresponding to the fabric parameters and sample fabric color, then after the necessary dyeing and subsequent color development is completed, the second fabric color is tested and then directly proceeded to mass production.

[0092] If it is found that there is no fabric parameter corresponding to dyed fabric 1 in the field jet dyeing database, three primary color dyes and one black dye are used to field jet dye the fabric using monochrome dyes of different concentrations, and the woven fabric is colored.

[0093] Among these, the second color detection device 130 detects the color parameters of the fabric before color development, and the first color detection device 120 detects the color parameters of the fabric after color development, and a new field jet dyeing database of the dyed fabric 1 is generated through a field jet dyeing database model based on the color parameters of the fabric before it is dyed and the color parameters of the fabric after it is dyed.

[0094] In the present invention, the color deviation threshold ΔE may be 0.5, although of course other values ​​are also contemplated.

[0095] The following non-limiting examples are used to further illustrate the present invention, but it should be noted that these examples should not be construed as limiting the present invention.

[0096] The specifications of dyed fabric 1 (including the specifications, density, fabric structure, etc. of the yarn of dyed fabric 1) will affect the final color expression of the dyeing, so in the specific implementation process, a corresponding field jet dyeing database is established based on the dyed fabric 1. Therefore, the sample processing process mainly involves two situations: 1. This fabric 1, 2 has a field jet dyeing database, and 2. This dyed fabric 1 does not have a field jet dyeing database.

[0097] The status of the field jet dyeing database can also be divided into 1-1, where the color of the sample fabric has been created, and 1-2, where the color of the sample fabric has not been created.

[0098] Example 1 For a color control system 100 used for four-color field jet dyeing, the machine creates a color for a sample fabric, and the parameters of dyed fabric 1 are already stored in the field jet dyeing database. The first color control process includes:

[0099] 1) The fabric parameters are input into the color control system 100, and the color of the sample fabric 2 is identified through the first color detection device 120. Then, the field jet dyeing database is searched, and the pre-coloring color parameters corresponding to the fabric of the sample fabric 2 can be used as the comparison sample parameters.

[0100] Combined with vehicle speed input to the color control system 100, the color control system 100 can provide precise field jet dyeing parameters (four-color dye concentration, spray volume, spray working distance, gas field parameters, electric field parameters, etc.).

[0101] 2) The dyed fabric 1 enters the dyeing production line, and the first four-color field jet dyeing device is used to dye the fabric based on the field jet dyeing parameters provided by the system.

[0102] After drying, a second color detection device 130 with a first four-color field jet dye device is used to identify and analyze the color and compare it to a reference sample in a field jet dye database.

[0103] If the parameters are the same or ΔE<0.5, the color development process can be carried out directly.

[0104] When the second color detection device 130 is used to identify the analyzed color, if the parameter difference with the reference sample in the field jet dye database is too large or if ΔE>0.5, then feedback is provided to the color control device 150.

[0105] The color control device 150 determines the color deviation based on the color deviation and the concentration of the current dye solution, and automatically provides adjustment parameters for field jet dyeing of a second four-color field jet dyeing device disposed downstream of the first four-color field jet dyeing device, thereby performing online adjustment dyeing.

[0106] After drying, a second color detection device 130 equipped with a second four-color field jet dyeing device is used to identify and analyze the color, which is compared with the contrast sample in the field jet dyeing database, and if ΔE<0.5, it can directly enter into the color development process.

[0107] Example 2 In the situation where the color control system 100 for four-color field jet dyeing has not produced sample fabric colors on this machine and the parameters of dyed fabric 1 have already been stored in the field jet dyeing database, the second color control process includes:

[0108] 1) Input the fabric parameters into the color control system 100 and identify the color of the sample fabric through the first color detection device 120. Thus, the field jet dyeing database can be searched, and the field jet dyeing database model can calculate and simulate the pre-coloring color parameters corresponding to the sample 2 fabric, which can be used as the comparison sample parameters. Combined with the vehicle speed input into the color control system 100, the color control system 100 can generate recommended field jet dyeing parameters (such as the concentration of the four color dyes, the spray amount, the spray working distance, the gas field parameters, the electric field parameters, etc.).

[0109] 2) The dyed fabric 1 enters the dyeing production line, and a first four-color field jet dyeing device is used to dye the fabric based on the recommended field jet dyeing parameters.

[0110] After drying, a second color detection device 130 with the first four-color field jet dye device is used to identify and analyze the color, which is compared to a reference sample in a field jet dye database.

[0111] If the parameters are the same or ΔE<0.5, it can enter the color development process directly. If the color identified and analyzed by the second color detection device 130 is significantly different from the parameters of the reference sample in the field jet dye database or ΔE>0.5, it will be fed back to the color control device 150.

[0112] The color control device 150 automatically provides adjustment parameters for the field jet dyeing of the second four-color field jet dyeing device disposed downstream of the first four-color field jet dyeing device based on the color deviation and the concentration of the current dye solution, and performs online adjusted dyeing.

[0113] After drying, the color is identified and analyzed using the second color detection device 130, which is arranged to correspond to the second four-color field jet dyeing device, and compared with the reference sample in the field jet dyeing database. If the parameters are the same or ΔE<0.5, the color development process can be directly started.

[0114] 3) Use the first color detection device 120 to identify the color of the fabric after color development, and if the color parameters are the same as those of the sample fabric 2 or ΔE < 0.5, then mass-produce the parameters based on the first color control process.

[0115] If the difference with the color parameters of the sample cloth 2 is too large or ΔE>0.5, it is fed back to the color control device 150, which provides an adjusted pre-colored contrast sample and recommended field jet dyeing parameters according to the difference between the two colors, and then repeats steps 2) and 3) of the second color control process until the color parameters are the same as those of the sample cloth 2 or ΔE<0.5.

[0116] The colour parameters of the sample fabric, the corresponding pre-colour parameters and the field jet dyeing parameters are then recorded in a field jet dyeing database.

[0117] Example 3 For a color control system 100 used for four-color field jet dyeing, if the field jet dyeing database does not contain the dyed fabric data of the sample fabric color, the third color control process includes:

[0118] 1) If fabric parameters are input into the color control system 100 and there is no corresponding field jet dyeing database model, a field jet dyeing database needs to be established first.

[0119] 2) Field jet dyeing is performed on the fabric using four monochrome colors with different densities: cyan, magenta, yellow, and black. The second color detection device 130 records the color parameters of the dyed fabric 1 before it is colored, and the color parameters of the dyed fabric 1 after it is colored are recorded using the first color detection device 120. Based on this, a field jet dyeing database of the dyed fabric 1 is automatically generated by the software of the field jet dyeing database model.

[0120] 3) Duplicate the process of the second color control.
