Description

Technical Field

[0001] The present invention relates generally to fabric dyeing control, and in particular, to methods, computing devices, computer readable storage media, and functional inks for dyeing a target fabric. Background Art

[0002] There are two main methods for dyeing fabrics: the first is an immersion dyeing method, and the second is a pad dyeing method.

[0003] The exhaust dyeing method is a method of immersing the dyed object in a dye solution containing dyes and necessary auxiliaries, and gradually dyeing the dyed object through the circulation of the dye solution or the movement of the dyed object. Although the exhaust dyeing method has the advantage of good level dyeing, its production efficiency is lower than that of continuous pad dyeing. In addition, exhaust dyeing requires a large amount of water and dye chemicals, which will cause a waste of resources, and the undyed dye chemical auxiliaries will cause environmental pollution.

[0004] In the pad dyeing method, the fabric is immersed in the dye solution for a short time, and then it is rolled with rollers to squeeze the dye solution into the interstices of the fabric, and the excess dye solution is removed, and then the dye is fixed by subsequent treatments such as steaming or drying. Although the pad dyeing method can improve production efficiency and improve the level of fabric dyeing to a certain extent, its process is relatively complicated, and there is still the problem of environmental pollution caused by the subsequent treatment of excess dye solution.

[0005] In summary, the traditional method of dyeing fabrics has the following disadvantages: it consumes a large amount of water and dyes, and the subsequent treatment of excess dye solution will cause environmental pollution. Summary of the invention

[0040] Figure 1 A schematic diagram of a system 100 for implementing a method for dyeing fabric according to an embodiment of the present invention is shown. Figure 1 As shown, the system 100 includes, for example, at least: a computing device 110, an image acquisition device 120, a pre-treatment liquid application device 130, and a spray-dyeing device 140. The image acquisition device 120, the pre-treatment liquid application device 130, and the spray-dyeing device 140 can exchange data with the computing device 110 in a wired or wireless manner through a network. The computing device 110 can be set in an integrated manner or in a discrete manner with the spray-dyeing device 140.

[0041] The image acquisition device 120 is used, for example, to acquire image data of the target fabric and provide the acquired image data to the computing device 110 so that the computing device 110 can calculate the width and density of the target fabric based on the image data.

[0042] The pre-treatment liquid application device 130 is configured in the pre-treatment liquid application area. The pre-treatment liquid application device 130 is used, for example, to apply the pre-treatment liquid to the target fabric. Specifically, the pre-treatment liquid application device 130 applies the pre-treatment liquid to the target fabric by dipping or padding, for example, based on the control instruction from the computing device 110.

[0043] Regarding the inkjet printing device 140, in some embodiments, it includes, for example, multiple groups of metering pumps, multiple primary ink cartridges, secondary ink cartridges, corresponding flow pumps, and multiple nozzles, such as Figure 4 As shown. The plurality of primary ink cartridges are used to contain a plurality of predetermined basic color inks and functional inks respectively. The secondary ink cartridge is used to contain a mixed ink obtained by mixing the predetermined basic color ink and the functional ink online. The plurality of nozzles are used to spray the ink to be sprayed. In other embodiments, the inkjet printing device 140 includes, for example, a plurality of metering pumps, a plurality of primary ink cartridges, a secondary ink cartridge, a corresponding front-stage flow pump, a tertiary ink cartridge, a corresponding rear-stage flow pump, and a plurality of nozzles, such as Figure 5 shown.

[0044] Regarding the inkjet device 140, in some embodiments, it is used to spray the ink to be sprayed formed by online mixing of multiple predetermined basic color inks and functional inks on at least one surface of the target fabric entering the inkjet area based on the control instructions from the computing device 110. In other embodiments, the inkjet device 140 is used to spray multiple predetermined basic color inks and functional inks on at least one surface of the target fabric based on the control instructions from the computing device 110. In some embodiments, each of the multiple nozzles is used to spray a mixed color, or one of the multiple predetermined basic color inks and functional inks. Each nozzle, for example, includes multiple nozzle needles or nozzle holes. In some embodiments, the multiple nozzles are, for example, arranged side by side longitudinally. In some embodiments, the multiple nozzle needles, nozzles or nozzle holes in the multiple nozzles are arranged at intervals.

[0045] Regarding the computing device 110, it is used to dye the target fabric. Specifically, the computing device 110 is used, for example, to determine the target liquid-carrying rate of the target fabric to be dyed; and based on the target color to be presented, respectively calculate the corresponding ink supply of each predetermined basic color ink in a plurality of predetermined basic color inks. The computing device 110 is also used to determine the ink supply of the functional ink based on the target liquid-carrying rate and the sum of the corresponding ink supply of the plurality of predetermined basic color inks; and based on the corresponding ink supply of each predetermined basic color ink and the ink supply of the functional ink, the plurality of predetermined basic color inks and at least one colorless functional ink are provided to the nozzle, so as to use the nozzle to dye the target fabric. In some embodiments, the computing device 110 may have one or more processing units, including dedicated processing units such as GPUs, FPGAs, and ASICs, and general processing units such as CPUs. In addition, one or more virtual machines may also be running on the computing device 110. In some embodiments, the computing device 110 includes, for example, a target liquid-carrying rate determining unit 112, a corresponding ink supply amount calculating unit 114 of a predetermined basic color ink, an ink supply amount determining unit 116 of a functional ink, and a predetermined basic color ink and functional ink providing unit 118. It should be understood that the target liquid-carrying rate determining unit 112, the corresponding ink supply amount calculating unit 114 of a predetermined basic color ink, the ink supply amount determining unit 116 of a functional ink, and the predetermined basic color ink and functional ink providing unit 118 are, for example, program modules running on the computing device 110.

[0046] Regarding the target liquid carrying rate determination unit 112, it is used to determine the target liquid carrying rate of the target fabric to be dyed, and the target liquid carrying rate indicates: within a unit area, the ratio of the weight of the ink to be sprayed output by the nozzle to the weight of the target fabric, the ink to be sprayed includes a plurality of predetermined basic color inks and at least one colorless functional ink, and the target liquid carrying rate is less than or equal to 100%.

[0047] The corresponding ink supply amount calculation unit 114 of the predetermined basic color ink is used to calculate the corresponding ink supply amount of each predetermined basic color ink among the plurality of predetermined basic color inks based on the target color to be presented.

[0048] The ink supply amount determining unit 116 for the functional ink is used to determine the ink supply amount of the functional ink based on the target liquid pick-up rate and the sum of the corresponding ink supply amounts of a plurality of predetermined basic color inks.

[0049] Regarding the predetermined basic color ink and functional ink providing unit 118, it is used to provide the multiple predetermined basic color inks and at least one colorless functional ink to the nozzle based on the corresponding ink supply amount of each predetermined basic color ink and the ink supply amount of the functional ink, so as to use the nozzle to dye the target fabric.

[0050] Figure 2 FIG. 2 is a flow chart of a method 200 for dyeing a target fabric according to an embodiment of the present invention. It should be understood that the method 200 can be implemented in Figure 7 The method 200 is executed at the described electronic device 700. It should be understood that the method 200 may further include additional actions not shown and / or may omit the actions shown, and the scope of the present invention is not limited in this respect.

[0051] At step 202, the computing device 110 determines a target liquid carrying rate of the target fabric to be dyed, wherein the target liquid carrying rate indicates: the ratio of the weight of the ink to be sprayed output by the nozzle to the weight of the target fabric per unit area, the ink to be sprayed includes a plurality of predetermined basic color inks and at least one colorless functional ink, and the target liquid carrying rate is less than or equal to 100%.

[0052] The target liquid pick-up rate indicates the ratio of the weight of the ink to be sprayed outputted by the nozzle to the weight of the target fabric per unit area (of the target fabric).

[0053] Regarding the weight of the target fabric, its unit weight is, for example but not limited to, "gram weight". It should be understood that "gram weight" refers to the number of weight units in grams under a standard measurement unit. Generally speaking, a larger unit weight indicates that the target fabric is thicker and / or denser.

[0054] Regarding the functional ink, it is colorless and is used to mix with a plurality of predetermined basic color inks to form the ink to be sprayed. In some embodiments, the functional ink includes: a dye solvent, a dye cosolvent, a wetting and diffusing agent, and a surfactant. Among them, the dye solvent is used to dissolve the plurality of predetermined basic color inks in the ink to be sprayed, accounting for 20 to 30% of the weight of the functional ink. The dye cosolvent accounts for 1 to 10% of the weight of the functional ink. The wetting and diffusing agent accounts for 0.1 to 2% of the weight of the functional ink. The surfactant accounts for 0.1 to 1% of the weight of the functional ink, and the other components of the functional ink are water. In some embodiments, the functional ink also includes a pH regulator and a bactericide. The pH regulator accounts for 0.01 to 0.1% of the weight of the functional ink. The bactericide accounts for 0.01 to 0.1% of the weight of the functional ink. In some embodiments, the dye solvent is, for example, one or more of ethylene glycol, propylene glycol, glycerol, diethylene glycol, dipropylene glycol, triethylene glycol, 1,2-pentanediol, and isoprene glycol. The dye cosolvent is, for example, one or more of urea, diethylene glycol ether, thiodiglycol, N-methylformamide, 2-pyrrolidone, caprolactam, polyethylene glycol, polypropylene glycol, acrylate copolymer, lignin sulfonate, sodium methyl naphthalene sulfonate, and sodium methylene disulfonate. The wetting and spreading agent is, for example, one or more of fatty alcohol polyoxyethylene ether, polyoxyethylene sorbitan ester, diisooctyl maleate sulfonate, etc. The surfactant is, for example, an acetylene glycol or polyether siloxane surfactant. It should be understood that the functional ink can be rapidly infiltrated by a variety of predetermined basic color inks, instantly dissolve the predetermined basic color ink, and drive the predetermined basic color ink to penetrate to the other side of the target fabric. In some embodiments, different predetermined basic color inks can penetrate to the bottom of the target fabric at the same speed under the action of the functional ink to compensate for the low liquid carrying rate because the relative migration value (R f value, or RF value or R f The problem of different penetration levels of different dyes caused by differences in color values) is solved, so as to achieve the effect of the same color on the front and back of the target fabric.

[0055] Regarding the target fabric, in some embodiments, it is, for example, a target fabric treated with a pre-treatment liquid. For example, the computing device 110 determines whether it is necessary to apply a pre-treatment liquid to the target fabric based on the acquired property information of the target fabric; in response to determining that it is necessary to apply a pre-treatment liquid to the target fabric and the target fabric enters the pre-treatment liquid application area, the pre-treatment liquid is applied to the target fabric, and the pre-treatment liquid application area is located before the spraying area. By adopting the above means, the present invention can prevent the migration of ink on the target fabric and further improve the uniformity and color fastness of the target color.

[0056] Regarding the pre-treatment liquid, it includes at least one of the following: a thickener, a cationic modifier, urea, salts, an acrylic copolymer, a surfactant, and a pH adjuster. It should be understood that the application of the pre-treatment liquid is conducive to the rapid penetration of the ink into the target fabric, further avoiding the occurrence of color spots and improving the leveling effect of dyeing.

[0057] At step 204 , the computing device 110 calculates the corresponding ink supply amount of each predetermined basic color ink among the plurality of predetermined basic color inks based on the target color to be presented.

[0058] Regarding the functional ink, it is, for example but not limited to, a colorless diluent, and the functional ink is configured to increase the permeability of the ink sprayed on the target fabric and to dilute the concentration of a plurality of predetermined basic color inks.

[0059] Regarding a plurality of predetermined basic color inks, in some embodiments, the color types of the predetermined basic color inks included therein are, for example, no more than four. In some embodiments, the color types of the predetermined basic color inks are, for example, three or four. For example, the predetermined basic color inks include, for example: a first predetermined basic color, a second predetermined basic color, and a third predetermined basic color. The three predetermined basic color inks are, for example, three primary color inks, i.e., red ink, yellow ink, and blue ink. It should be understood that by making the color types of the predetermined basic color inks included in the plurality of predetermined basic color inks no more than four, the target color after mixing with the functional ink can be made purer. In other embodiments, the plurality of predetermined basic color inks include, for example, CMYK (i.e., cyan, red, yellow, and black) four-color inks.

[0060] Regarding the method for determining the total ink supply of the ink to be sprayed, for example, it includes: the computing device 110 makes the ratio of the total ink supply of the ink to be sprayed formed by online mixing of multiple predetermined basic color inks and functional inks to the unit weight of the target fabric between 20% and 60%. In some embodiments, the ratio of the total ink supply of the ink to be sprayed to the unit weight of the target fabric is between 20% and 50%. By adopting the above means, it is further beneficial to the online mixing of high-concentration predetermined basic color inks to achieve a level dyeing effect.

[0061] At step 206 , the computing device 110 determines the ink supply amount of the functional ink based on the target liquid pick-up rate and the sum of the corresponding ink supply amounts of the plurality of predetermined basic color inks.

[0062] Regarding the method for determining the ink supply of the functional ink, it for example includes: calculating the total ink supply of the ink to be sprayed based on the target liquid carrying rate for a unit area of ​​the target fabric; and subtracting the sum of the corresponding ink supply of multiple predetermined basic color inks from the calculated total ink supply of the ink to be sprayed to determine the ink supply of the functional ink.

[0063] In some embodiments, regarding the ink supply of the functional ink, it includes, for example, the corresponding ink supply component of the functional ink for online mixing with each predetermined basic color ink. In some embodiments, the ink supply of the functional ink includes, for example, a first ink supply component of the functional ink corresponding to the first predetermined basic color ink, a second ink supply component of the functional ink corresponding to the second predetermined basic color ink, and a third ink supply component of the functional ink corresponding to the third predetermined basic color ink.

[0064] In some embodiments, the ink supply corresponding to each predetermined basic color ink includes, for example: a first corresponding ink supply of a first predetermined basic color ink, a second corresponding ink supply of a second predetermined basic color ink, and a third corresponding ink supply of a third predetermined basic color ink.

[0065] In some embodiments, the computing device 110 uses RIP software to adjust the optimal blending ratio of different color gamut ranges based on the target color, thereby determining the corresponding ink supply of each predetermined basic color ink and the corresponding ink supply component of the corresponding functional ink.

[0066] For example, first, the computing device 110 obtains the L, a, and b values ​​of the Lab color model of the target color measured by the color measuring device. It should be understood that the Lab color model is a device-independent color model. Among them, L represents brightness, and a and b represent the values ​​of two color channels respectively. Then, according to the L, a, and b values ​​of the Lab color model of the measured target color, the ink supply corresponding to each predetermined basic color ink is given based on the predetermined density curve and the color management system ICC. Among them, Figure 8 Schematic diagrams of predetermined density curves of the first to fourth predetermined basic colors according to an embodiment of the present invention are respectively shown. Among them, mark 810 indicates the predetermined density curve of the first predetermined basic color in CMYK. Mark 820 indicates the predetermined density curve of the second predetermined basic color. Mark 830 indicates the predetermined density curve of the third predetermined basic color. Mark 840 indicates the predetermined density curve of the fourth predetermined basic color. The horizontal axis corresponding to each predetermined density curve represents the amount of the predetermined basic color; the vertical axis represents the color depth density value, and the value range is 0%-100%. Afterwards, the computing device 110 fits the functional ink usage curve based on the unit weight (e.g., gram weight) of the target fabric and the liquid carrying rate associated with the target fabric, so as to make the predetermined basic color consistent with the total ink supply of the functional ink. Fig. 9 FIG. 1 is a schematic diagram showing a functional ink usage curve according to an embodiment of the present invention. Fig. 9 In the figure, the horizontal axis represents the color depth, and the vertical axis represents the ink supply, with a value range of 0%-100%. Mark 910 indicates the predetermined basic color ink usage curve; mark 920 indicates the functional ink usage curve. The following formula (1) illustrates the calculation formula for the corresponding ink supply and of the predetermined basic color ink.

[0067] Y=Y1+Y2 (1)

[0068] In the above formula (1), Y represents the actual total ink supply amount, Y1 represents the ink supply amount of the functional ink, and Y2 represents the ink supply amount of the predetermined basic color ink.

[0069] At step 208 , the computing device 110 supplies the plurality of predetermined basic color inks and at least one colorless functional ink to the printhead based on the corresponding ink supply amount of each predetermined basic color ink and the ink supply amount of the functional ink, so as to dye the target fabric using the printhead.

[0070] Regarding the method for dyeing the target fabric using the nozzle, in some embodiments, it includes, for example: controlling the nozzle based on the corresponding ink supply of each predetermined basic color ink and the ink supply of the functional ink, so as to spray each predetermined basic color ink and the functional ink on the target fabric, so as to mix the predetermined basic color ink and the functional ink on the target fabric, so that the target fabric presents the target color; mixing based on the corresponding ink supply of each predetermined basic color ink and the ink supply of the functional ink, so as to spray the mixed ink to be sprayed on the target fabric via the nozzle, so that the target fabric presents the target color. It should be understood that in some embodiments, the present invention provides a method of first mixing multiple predetermined basic color inks and functional inks online for online color mixing; and then using the ink to be sprayed that is first mixed to spray the fabric into the target color. In other embodiments, the nozzle of the dyeing device can be controlled based on the corresponding ink supply of each predetermined basic color ink and the ink supply of the functional ink, so as to spray the predetermined basic color ink and the functional ink on the target fabric, so as to mix the predetermined basic color ink and the functional ink on the target fabric, so that the target fabric presents the target color. It should be understood that the above embodiments provide a method of directly mixing the predetermined basic color ink and the functional ink on the target fabric so that the target fabric presents the target color. In other embodiments, the functional ink can be mixed with each predetermined basic color ink online, and then the mixed ink and the functional ink of another channel are sprayed on the target fabric respectively, so as to mix the colors on the target fabric, so that the target fabric presents the target color.

[0071] It should be understood that, whether it is the online color mixing method of the present invention or the color mixing method on the target fabric, since the functional ink is added and the ink supply of each predetermined basic color ink and the ink supply of the functional ink are calculated based on the unit weight of the target fabric to be sprayed to control the spraying equipment, it can not only avoid: when printing light colors in the traditional fabric dyeing method, it is difficult to achieve uniform mixing of different color inks due to complete penetration. The phenomenon caused by the pitting phenomenon; and it can also avoid: the color difference of the feathering path caused by the deviation of the printing sequence of different inks during the continuous printing process of different nozzles. In addition, since the traditional digital printing dyes are mainly CMYKOB and 9 kinds of monochrome dyes of light cyan, light red, and gray, the color gamut of the 9 kinds of monochrome dyes is limited relative to the dyes used for dyeing (more monochrome dyes are used), so that individual bright or special colors cannot be dyed using the digital printing process. The present invention controls the spray-dyeing equipment by adding functional inks and calculating the corresponding ink supply of each predetermined basic color ink and the ink supply of the functional ink based on the unit weight of the target fabric to be sprayed, thereby achieving more color mixing. Even for individual bright or special colors, the digital printing process can be used to dye the fabric.

[0072] Regarding the method for making the target fabric present a target color, in some embodiments, it includes, for example: spraying the ink to be sprayed on the first surface of the target fabric so that the first surface of the target fabric presents a first target color; and spraying the ink to be sprayed on the second surface of the target fabric so that the second surface of the target fabric presents a second target color, wherein the ratio of the colorant absorption coefficient to the colorant scattering coefficient of the first target color and the second target color is less than or equal to 10%, or the first target color is the same as or different from the second target color. By adopting the above means, the present invention can make the two sides of the target fabric the same color or different colors.

[0073] There may be multiple methods for forming ink to be sprayed by online mixing of multiple predetermined basic color inks and functional inks. For example, in some embodiments, the corresponding ink supply of each predetermined basic color ink and the corresponding ink supply component of the functional ink corresponding to each predetermined basic color ink are controlled by means of a shunt flowmeter or multiple groups of metering pumps. The metering pump is, for example, any one of a diaphragm pump, a peristaltic pump, and a gear pump. For example, by detecting the flow of the predetermined basic color ink or functional ink in the channel, the metering pump is turned off after the flow reaches the respective set ink supply (or ink supply component), thereby achieving ink volume control of the predetermined basic color ink or functional ink, and multiple ink injections can be achieved simultaneously for efficient online color mixing.

[0074] In some embodiments, a method for spraying the ink to be sprayed mixed online onto at least one surface of a target fabric includes, for example: the computing device 110 controls a first group of metering pumps to mix a first predetermined basic color ink of a first corresponding ink supply amount and a functional ink of a first ink supply component from a first primary ink cartridge at a first secondary ink cartridge to generate a first mixed color ink; controls a second group of metering pumps to mix a second predetermined basic color ink of a second corresponding ink supply amount and a functional ink of a second ink supply component from a second primary ink cartridge at a second secondary ink cartridge to generate a second mixed color ink; controls a third group of metering pumps to mix a third predetermined basic color ink of a third corresponding ink supply amount and a functional ink of a third ink supply component from a third primary ink cartridge at a third secondary ink cartridge to generate a third mixed color ink; and controls corresponding flow pumps to respectively provide the first mixed color ink, the second mixed color ink and the third mixed color ink to corresponding nozzles of a dyeing device, so as to be used to spray the ink to be sprayed onto at least one surface of a target fabric. The following will be combined with Figure 3 and Figure 4 The specific implementation of the method for spraying the online mixed ink to be sprayed onto at least one surface of the target fabric is described in detail, which will not be repeated here.

[0075] In the above scheme, the present invention can accurately calculate the matching amount of ink to be sprayed according to the average weight of the target fabric, effectively avoiding the environmental pollution caused by excess ink. In addition, by controlling the spraying equipment based on the corresponding ink supply of each predetermined basic color ink and the ink supply of the functional ink, the ink to be sprayed formed by online mixing of multiple predetermined basic color inks and functional inks is sprayed on at least one surface of the target fabric entering the spraying area, so that the target fabric presents the target color. The present invention can not only reduce the waste of water resources and the use of dyes and chemicals, and significantly reduce the environmental pollution caused by excess dyeing liquid, but also use the functional ink and the spot color ink of the predetermined basic color to mix online or on the fabric, which is conducive to the mutual fusion of the predetermined basic color to achieve a uniform dyeing effect within different color ranges, avoiding the high color concentration of direct spot color dyeing, and the unevenness such as pockmarks and spots that are easy to appear in spraying and immersion dyeing, and is more suitable for small batch and multi-variety dyeing. .

[0076] The following combination Figure 3 , Figure 4 A method 300 is described for spraying an in-line mixed ink to be sprayed onto at least one surface of a target fabric.
