Color control system

Abstract

We provide a color control system for 4-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.

Summary of the Invention

Problems to be Solved by the Invention

[Figure 2a] 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. [Figure 2b] 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. [Figure 3] This is a flowchart of a color control method for four-color field jet staining based on an embodiment of the present invention. [Modes for carrying out the invention]

[0023] 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 combinations of technically feasible functions are included in the technical content described in the specification.

[0024] 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.

[0025] 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.

[0026] To better detect the color of the sample cloth 2, the first color detection device 120 can be placed above the sample cloth stand.

[0027] Through the obtained sample fabric color 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 sample fabric color exist in the field jet dyeing database. Based on this, temporary pre-color parameters are generated or planned pre-color parameters are obtained, and in this way, the corresponding contrast sample parameters are determined and used as a criterion for determining the degree of color deviation during dyeing.

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

[0029] The four 4-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 one side can be dyed by using only two of the 4-color field jet dyeing devices 110 on one side.

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

[0031] The four-color field jet staining apparatus 110 is configured for four-color field jet staining using three primary color dyes and one black dye. In this embodiment, each of the four-color field jet staining apparatus 110 is configured as a four-color nozzle for four-color field jet staining.

[0032] In this embodiment, the four-color nozzle has four dyeing nozzles, each of which is designed to spray a dye of one of the three primary colors and black by a field jet. Of course, the present invention is not limited thereto, and it is also possible to provide any other number of dyeing nozzles.

[0033] 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.

[0034] When two or more 4-color field jet staining devices 110 are installed on the same side, the downstream 4-color field jet staining device 110 can achieve complementary colors. Here, complementary colors can be achieved by adjusting the 4-color field jet staining parameters based on online color detection, thereby achieving online adjusted staining.

[0035] Of course, even if only one 4-color field jet staining device 110 is installed on the same side, online adjustment staining can be performed. The 4-color field jet staining device 110 can adjust its own 4-color field jet staining parameters in real time based on downstream online color detection, thus maximizing the advantages of 4-color staining and reducing color deviation (color discrepancy) with the parameters of the comparison sample by changing the parameters unique to 4-color field jet staining.

[0036] As shown in Figure 1, the color control system 100 also includes a heating device 140 located downstream of the four-color field jet dyeing apparatus 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 of the fabric.

[0037] In this embodiment, the heating device 140 is configured as an oven. The oven can heat the dye using thermal radiation to fix the color. In other embodiments, the heating device 140 can also be configured as a hot air heater that can heat the dye using hot air to achieve color fixation.

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

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

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

[0041] In this embodiment, the second fabric color may be detected by a color detection device other than the first color detection device 120 and the second color detection device 130.

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

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

[0044] The color control device 150 communicates 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 can also communicate with the storage device to read data from the storage device or save data to the storage device.

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

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

[0048] If the first fabric color deviation is below the color deviation threshold, the process proceeds directly to the color development stage.

[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 apparatus 110 is prompted to perform online adjustment dyeing based on the adjusted field jet dyeing parameters until the first fabric color deviation is less than or equal to the color deviation threshold.

[0050] Furthermore, if the field jet dyeing database does not contain fabric parameters or pre-color parameters corresponding to the color of the sample fabric, the second fabric color after color development, detected by the first color detection device 120 after the fabric has been dyed, may be input to the color control device 150.

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

[0052] If the color deviation of the second fabric is below the color deviation threshold, mass production is carried out based on the field jet dyeing parameters used in the dyeing process prior to 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 field jet dyeing parameters are readjusted and the dyeing and color development are repeated until the color deviation of the second fabric falls below the color deviation threshold.

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

[0055] As shown in Figure 1, in the dyeing production line for dyed fabric 1, the four-color field jet dyeing apparatus 110, the heating apparatus 140, and the second color detection apparatus 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 the four-color dyeing and color detection assemblies are arranged in pairs on both sides of the dyed fabric 1. In other embodiments, there may be two, six, eight, and so on groups of the four-color dyeing and color detection assemblies.

[0057] In short, Figure 1 shows the following: In each of the four-color staining and color detection assemblies, only one of the corresponding devices is assigned a reference number.

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

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

[0060] The integrated color detection 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 positioned at the location of the specular reflection hole of the integrating sphere 230.

[0061] The color sensor 210 is positioned to receive light emitted from the light-receiving hole of the integrating sphere 230, and the lens 250 is positioned between the light-receiving hole of the integrating sphere 230 and the color sensor 210.

[0062] The colored light is received by the color sensor 210, and the received colored light is corrected by the spectral response curve and the color difference result calculated therefrom. 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] Multiple, preferably 16, photodiodes can be integrated onto a single chip of the color sensor 210. Here, preferably, four of the multiple photodiodes have a red filter.

[0064] Of the plurality of photodiodes, four second photodiodes in particular have green filters, four third photodiodes in particular have blue filters, and the remaining photodiodes do not have filters.

[0065] As shown in Figure 2b, 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 a spectrometer 310.

[0066] The integrated color detection camera head includes a light source 320, an integrating sphere 330, a light trap 340, a lens 350, and an optical fiber head 360, with the optical fiber head 360 and the spectrometer connected via an optical fiber 370.

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

[0068] Color light is received by the optical fiber head 360, and the received color light can be transmitted to the spectrometer 310 via the optical fiber 370. The output terminal of the spectrometer 310 is also communicated with the input terminal of the color control device 150.

[0069] In the first color detection device 120 and / or the second color detection device 130, which have two different configurations, the light sources 220 and 320 may be configured as coaxial light sources equipped with LED arrays.

[0070] Light sources 220 and 320 can be selected from a group that includes CIE standard light sources, C standard light sources, and D series standard light sources such as D50, D65, D75, and F standard light sources.

[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 spheres 230 and 330 can be configured as d / 8 degree integrating spheres. The side walls of the integrating spheres 230 and 330 are provided with an entrance opening, and light emitted from the light source enters the integrating spheres 230 and 330 through the entrance opening. The dyed fabric 1 is located at the lower opening of the integrating spheres 230 and 330.

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

[0074] The field jet staining parameters include at least one of the following parameters: the concentration of the dye ejected from each four-color field jet staining apparatus 110, the amount of dye sprayed by each four-color field jet staining apparatus 110, the spraying operating distance of each four-color field jet staining apparatus 110, the gas field parameter of each four-color field jet staining apparatus 110, and the electric field parameter of each four-color field jet staining apparatus 110.

[0075] The following describes a color control method for four-color field jet staining according to an embodiment of the present invention, with reference to Figure 3.

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

[0077] After obtaining the fabric parameters for dyed fabric 1, the system checks whether fabric parameters corresponding to dyed fabric 1 already exist in the fieldjet dyeing database. If they do exist and the answer is "yes," the system proceeds directly to the next step. If they do not exist and the answer is "no," fabric parameters corresponding to dyed fabric 1 are created in the fieldjet dyeing database.

[0078] Next, the color of the sample cloth 2 is acquired, for example, by the first color detection device 120. After acquiring the color of the sample cloth, the field jet dyeing database is checked to see if there are pre-color parameters corresponding to the fabric parameters and the color of the sample cloth.

[0079] If "yes," the pre-color parameters in the field jet dyeing database are used as reference sample parameters, field jet dyeing parameters are generated based on the reference sample parameters, and the fabric is dyed.

[0080] If the answer is "No," then temporary pre-color parameters are generated based on the fabric parameters and the color of the sample fabric, and these temporary pre-color parameters are used as the contrast sample parameters. Field jet dyeing parameters are generated based on the contrast sample parameters for dyeing the fabric. Here, the field jet dyeing parameters are generated based on the contrast sample parameters and the entered vehicle speed.

[0081] The temporary coloration parameters are calculated and simulated through a field jet staining database model.

[0082] Next, when dyeing the fabric using field jet dyeing parameters, the first four-color field jet dyeing apparatus 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 apparatus 130, and the first fabric color is compared with the contrast sample parameters to obtain the deviation of the first fabric color.

[0083] If the first fabric color deviation is below the color deviation threshold, the process proceeds directly to the color development stage.

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

[0085] As mentioned above, online adjustment staining can be completed using the first four-color field jet staining apparatus and the second four-color field jet staining apparatus. Colors can also be supplemented using the second four-color field jet staining apparatus, or color supplementation can be completed using the first four-color field jet staining apparatus itself.

[0086] In other words, the field jet dyeing parameters of the first four-color field jet dyeing apparatus itself are adjusted in real time based on the detection results of the downstream color deviation. Here, the field jet dyeing parameters adjusted for the first four-color field jet dyeing apparatus and / or the second four-color field jet dyeing apparatus are provided based on the first fabric color deviation and the current dye concentration.

[0087] If it is found that the planned pre-color parameters corresponding to the fabric parameters and sample color do not exist in the field jet dyeing database, after the fabric has developed color, the color of the second fabric after color development 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] Of these, if the color deviation of the second fabric is below 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 prior to 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 field jet dyeing parameters are readjusted, and dyeing and color development are repeated until the color deviation of the second fabric falls below the color deviation threshold.

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

[0091] Furthermore, if it is found that the field jet dyeing database contains fabric parameters and pre-color parameters corresponding to the color of the sample fabric, a second fabric color will be tested after the necessary dyeing and subsequent color development are complete, and then mass production will proceed.

[0092] If it is found that no fabric parameters corresponding to dyed fabric 1 exist in the field jet dyeing database, the fabric will be field jet dyed using three primary dyes and one black dye, with different concentrations of single-color dyes, and the fabric will be colored.

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

[0094] In this invention, the color deviation threshold ΔE may be 0.5. Of course, other values ​​can also be considered.

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

[0096] The specifications of dyed fabric 1 (including the yarn specifications, density, and weave structure of dyed fabric 1) affect the final color expression of the dye. Therefore, in the actual implementation process, a corresponding field jet dyeing database is established based on dyed fabric 1. For this reason, two main situations are involved in the sample processing process: 1. Fabrics 1 and 2 have a field jet dyeing database, and 2. Dyed fabric 1 does not have a field jet dyeing database.

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

[0098] Example 1 In the case of the color control system 100 used for 4-color field jet dyeing, if the machine creates the color of the sample fabric and the parameters of the dyed fabric 1 are already stored in the field jet dyeing database, the first color control process includes the following:

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

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

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

[0102] After drying, the color is identified and analyzed using a second color detection device 130 equipped with a first four-color field jet staining device, and compared to a reference sample in a field jet staining database.

[0103] If the parameters are the same, or if ΔE < 0.5, the color development process can proceed directly.

[0104] When identifying a color analyzed using the second color detection device 130, if the parameter difference with a reference sample in the field jet staining database is too large, or if ΔE > 0.5, the results are fed back to the color control device 150.

[0105] The color control device 150 determines the color deviation based on the color deviation and the current dye solution concentration. It automatically provides the field jet staining adjustment parameters for the second four-color field jet staining device, which is located downstream of the first four-color field jet staining device, and performs online adjustment staining.

[0106] After drying, the color is identified and analyzed using a second color detection device 130 equipped with a second four-color field jet staining device, and compared with a reference sample in the field jet staining database. If ΔE < 0.5, the color development process can proceed directly.

[0107] Example 2 In the case where the color control system 100 for 4-color field jet dyeing has not created the color of the sample fabric on this machine, and the parameters of the dyed fabric 1 are already stored in the field jet dyeing database, the second color control process includes the following:

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

[0109] 2) The dyed fabric 1 enters the dyeing production line and is dyed using the first four-color field jet dyeing apparatus based on the recommended field jet dyeing parameters.

[0110] After drying, the color is identified and analyzed using a second color detection device 130 equipped with a first four-color field jet staining device, and compared to a reference sample in a field jet staining database.

[0111] If the parameters are the same or ΔE < 0.5, the color development process can proceed directly. If the color identified and analyzed by the second color detection device 130 differs significantly from the parameters of a reference sample in the field jet staining database, or if ΔE > 0.5, the results are fed back to the color control device 150.

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

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

[0114] 3) The color of the fabric after color development is identified using the first color detection device 120. If the color parameters are the same as those of the sample fabric 2, or if ΔE < 0.5, then mass production is carried out based on the first color control process.

[0115] If the difference between the color parameters of sample cloth 2 and the sample cloth is too large, or if ΔE > 0.5, the color control device 150 is fed back and provides a pre-color development comparison sample adjusted for the difference between the two colors and recommended field jet staining parameters. The second color control process then repeats steps 2) and 3) until the color parameters become the same as those of sample cloth 2 or ΔE < 0.5.

[0116] Next, the color parameters of the sample fabric, the corresponding pre-color parameters, and the field jet staining parameters are recorded in the field jet staining database.

[0117] Example 3 In the case of the color control system 100 used for 4-color field jet dyeing, if the field jet dyeing database does not contain the dyed fabric data for the color of the sample cloth, the third color control process includes the following:

[0118] 1) If fabric parameters are entered into the color control system 100 and there is no corresponding field jet staining database model, it is necessary to first establish a field jet staining database.

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

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