Description

[Technical Field]

[0001] The present invention relates to a dyeing installation, in particular to a dyeing installation for a waterless dyeing system. [Background technology]

[0002] In the waterless dyeing technology for polyester fiber described in Patent Document 1, the crushed dye is placed in a dye tank, and then the dye in the dye tank is injected into a digital printing machine in the dyeing equipment using a pressure pump, and the nozzle of the digital printing machine is sprayed onto a horizontally placed fabric to perform printing. However, in this case, the color of the dye needs to be adjusted in advance before being injected into the dye tank, so the color cannot be adjusted in real time.

[0003] Furthermore, the dyeing equipment for dyeing yarn is configured to have, for example, a plurality of dye tanks each containing dyes of a specific color (for example, three primary colors), a dye mixing tank, a dye output device, pipes arranged between each dye tank and the dye mixing tank, and between the dye mixing tank and the dye output device, and pumps arranged on each pipe.

[0004] With this configuration, the ratio at which dye of a specific color contained in the dye tank is output to the dye mixing tank can be controlled by each pump, so that the dye is mixed with the mixed dye of the desired color in the dye mixing tank, and then output to the dye output device to dye the yarn in the desired color.

[0005] However, for example, if the lengths of the pipes are different, controlling the pressure with the pump may not allow for accurate control of the ratio of dyes of each color output to the dye mixing tank, and the desired color of dye may not be mixed, so there is still room for improvement.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a dyeing installation with a waterless dyeing system that overcomes at least one of the drawbacks of the prior art. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention provides a dyeing equipment for an anhydrous dyeing system used to output a dye to an object to be dyed, comprising: at least two dye supply means each having a dye storage can containing a dye and a dye supply guide tube connected to the dye storage can; a dye mixing box connected downstream of the dye supply guide pipe of each of the dye supply means; a dye injection means having at least one dye output guide pipe connected downstream of the dye mixing box and at least one flow path connected to the dye output guide pipe and used to output dye to the object to be dyed; and at least two pump means respectively arranged in each of the dye supply guide pipes, each of the pump means being configured to have, in a dye supply direction, an input pump configured to have an adjustable flow rate, a temporary storage case connected to the input pump, and an output pump connected to the temporary storage case and configured to have an adjustable flow rate. [Effects of the Invention]

[0009] The dyeing equipment of the waterless dyeing system of the present invention temporarily stores some of the dye in a temporary storage case and manages the dye water level in the temporary storage case. This makes it possible to accurately control the pressure and flow rate of the dye output from the temporary storage case to the dye mixing box or each passage, even when the dye pressure in the dye supply means or dye mixing box changes and the pipe lengths of the dye supply guide pipes and the dye output guide pipes are different. This improves the degree of dye mixing and the accuracy and quality of yarn dyeing, while maintaining the dye absorption by the yarn to be dyed at a saturation absorption amount and preventing the yarn from absorbing too much or too little dye, thereby improving the yarn dyeing quality.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention will now be described in detail with reference to the accompanying drawings and examples.

[0012] As shown in Figures 1 to 3, a first embodiment of the dyeing equipment of the waterless dyeing system of the present invention is for outputting dye to a dyeing object 8 consisting of a plurality of yarns 81 made of, for example, polyester, nylon, TPU, TPEE, cotton, polypropylene, or acrylic, and this dyeing equipment of the waterless dyeing system is configured to include a plurality of dye supplying means 1, a dye mixing box 2, an agitating means 3, a temperature control means 4, a dye injection means 5, a plurality of pumping means 6, and a control means 7.

[0013] Each dye supply means 1 is used to output a different color dye to the dye mixing box 2. Each dye supply means 1 has a dye storage can 11 used to store dye, and a dye supply guide pipe 12 connected between the dye storage can 11 and the dye mixing box 2. In this embodiment, there are five dye storage cans 11, four of which are used to store four color dyes (CMYK) of cyan, magenta, yellow, and black (Key plate), and the remaining one is used to store transparent (or colorless) dye. Note that the number of dye storage cans 11 is not limited to the present invention; for example, three cans can be installed to store three color dyes (RGB) of red, green, and blue.

[0014] The dye mixing box 2 is located downstream (in the dye supply path) of the dye supply means 1. The dye mixing box 2 is connected to each dye supply guide pipe 12, so that the dyes from each dye storage can 11 are mixed in the dye mixing box 2 to become a mixed dye of the color with which the object 8 to be dyed will be dyed.

[0015] The stirring means 3 is disposed in the dye mixing box 2 and is used to stir and mix the dyes output from each dye storage can 11 to the dye mixing box 2. Specifically, the stirring means 3 in this embodiment has an impeller 31 rotatably disposed in the dye mixing box 2 and used to stir the dyes, and a motor 32 disposed in the dye mixing box 2 and used to drive the impeller 31.

[0016] The temperature control means 4 has a heater 41 disposed in the dye mixing box 2 and used to heat the dye in the dye mixing box 2, and a temperature sensor 42 disposed in the dye mixing box 2 and used to detect the temperature of the dye in the dye mixing box 2. Incidentally, an electric heating tube or an electric heating plate can be used as the heater 41.

[0017] 1, 2, and 4, the dye injection means 5 is located downstream (of the dye supply path) of the dye mixing box 2. The dye injection means 5 includes a lower base 51, an upper base 52 arranged above the lower base 51 in the vertical direction Z, a plurality of dye output guide tubes 54 arranged in the dye mixing box 2, a plurality of nozzle devices 55 arranged between the lower base 51 and the upper base 52 so as to be connected to each dye output guide tube 54, a plurality of dye discharge guide tubes 56 (only one is shown in FIG. 1 due to the drawing angle) arranged in the lower base 51, and a suction device 57 communicating with each dye discharge guide tube 56. In this embodiment, a different type of pump can be used as the suction device 57.

[0018] 2, 4, and 5, the lower base 51 has a first inner surface 511 facing the upper base 52 along the vertical direction Z, a first outer surface 512 on the opposite side of the first inner surface 511 along the vertical direction Z, a plurality of lower grooves 513 formed in the first inner surface 511, a plurality of first lower flow paths 514 extending from the first outer surface 512 to each of the lower grooves 513, a plurality of second lower flow paths 515 extending from the first outer surface 512 to each of the lower grooves 513, and a plurality of dye discharge flow paths 516 extending from the first outer surface 512 to each of the lower grooves 513. The lower grooves 513 extend along a first horizontal direction X perpendicular to the vertical direction Z and are spaced apart from one another in a second horizontal direction Y perpendicular to both the vertical direction Z and the first horizontal direction X. Each of the first downstream channels 514, each of the second downstream channels 515, and each of the dye discharge channels 516 extends along the vertical direction Z. Each of the second downstream channels 515 is disposed between the corresponding first downstream channel 514 and dye discharge channel 516. In this embodiment, the first horizontal direction X is perpendicular to the second horizontal direction Y and perpendicular to the vertical direction Z.

[0019] The upper base 52 has a second inner surface 521 abutting against the first inner surface 511, a second outer surface 522 opposite the second inner surface 521 in the vertical direction Z, a plurality of upper grooves 523 formed in the second inner surface 521, a plurality of first upstream flow paths 524 extending from the second outer surface 522 to each of the upper grooves 523, and a plurality of second upstream flow paths 525 extending from the second outer surface 522 to each of the upper grooves 523. Each of the upper grooves 523 extends along the first horizontal direction X and is spaced apart from one another in the second horizontal direction Y. Each of the upper grooves 523 is connected to a corresponding lower groove 513 to form a single passage 53. Each of the first upstream flow paths 524 and each of the second upstream flow paths 525 extend along the vertical direction Z. Each of the first upstream paths 524 faces one corresponding first downstream path 514 , and each of the second upstream paths 525 faces one corresponding second downstream path 515 .

[0020] Each nozzle device 55 is provided to correspond to each of the first upstream flow paths 524, the second upstream flow paths 525, the first downstream flow paths 514, and the second downstream flow paths 515. Each nozzle device 55 has a connecting portion 551 that communicates with a corresponding dye output guide pipe 54 on the side away from the corresponding passage 53, and a nozzle head 552 that extends from the connecting portion 551 to the corresponding passage 53. Each connecting portion 551 is attached to the corresponding passage (first upstream flow path 524, second upstream flow path 525, first downstream flow path 514, or second downstream flow path 515) by a screw thread (not shown) formed on its outside. Each nozzle head 552 communicates with its corresponding connecting portion 551, thereby outputting dye from the dye output guide pipe 54 connected to the corresponding connecting portion 551 to the corresponding passage 53.

[0021] It should be noted that the specific configuration of each nozzle device 55 is not limited to this example, and different types of dye injection structures can be used. For example, the nozzle device 55 can be a spray nozzle, a thermal transfer nozzle head, or a direct dye jet nozzle head.

[0022] 1, 2, and 5, each passage 53 is used for passing yarn 81 to be dyed. The dye injection means 5 outputs the mixed dye mixed in the dye mixing box 2 to the yarn 81 passing through the passage 53 using each of the first upstream passages 524, each of the second upstream passages 525, each of the first downstream passages 514, and each of the second downstream passages 515.

[0023] Each dye discharge guide pipe 56 is connected to each dye discharge flow path 516, and a suction device 57 sucks out and discharges excess dye in each passage 53 via each dye discharge flow path 516 and each dye discharge guide pipe 56.

[0024] A pump means 6 is provided for each dye supply guide pipe 12 and each dye output guide pipe 54. A corresponding pump means 6 is provided for each dye supply guide pipe 12 at a position close to the dye mixing box 2, and a corresponding pump means 6 is provided for each dye output guide pipe 54 at a position close to the corresponding first upstream flow path 524 or second upstream flow path 525 or first downstream flow path 514 or second downstream flow path 515.

[0025] Each pump means 6 includes an input pump 61 configured to have an adjustable flow rate, a temporary storage case 62 made of a light-transmitting material and containing the dye, a scale 63 arranged on the temporary storage case 62, a water level meter 64 arranged on the temporary storage case 62 and used to detect the dye level in the temporary storage case 62, and an output pump 65 configured to have an adjustable flow rate. The input pump 61, temporary storage case 62, and output pump 65 are arranged in order in a holding frame (not shown) along the dye supply path. In this embodiment, precision micro-feed pumps are used as each input pump 61 and each output pump 65, but in the present invention, they may also be tube pumps, gear pumps, screw pumps, servo pumps, piezo pumps, or the like.

[0026] Each temporary storage case 62 upstream of the dye mixing box 2 is located at the same height, and each temporary storage case 62 upstream of each first upstream flow path 524 and each second upstream flow path 525 is located at the same height, and further, each temporary storage case 62 upstream of each first downstream flow path 514 and each second downstream flow path 515 is located at the same height.

[0027] 2 and 3, the control means 7 is electrically connected to each input pump 61, each output pump 65, each water level meter 64, and the temperature sensor 42. In this embodiment, a programmable logic controller (PLC) is used as the control means 7. As a result, the control means 7 controls the flow rate of the corresponding input pump 61 and / or output pump 65 based on the dye level of the dye detected by each water level meter 64, thereby maintaining the dye level of the dye in the corresponding temporary storage case 62 at a target level. Alternatively, a user can manually adjust the flow rate of the corresponding input pump 61 and corresponding output pump 65 by visually checking the corresponding scale 63, thereby maintaining the dye level of the dye in the corresponding temporary storage case 62 within a predetermined range.

[0028] Furthermore, the control means 7 controls the heater 41 based on the dye temperature detected by the temperature sensor 42 to heat the dye in the dye mixing box 2 to a target temperature, thereby improving dyeing efficiency and uniformity. For example, when the dye temperature reaches 40°C, nylon fiber begins to absorb the dye, and as the temperature rises, the dyeing speed increases. When the dye temperature reaches 100°C, the dye transfer is almost complete; therefore, controlling the temperature in this way improves dyeing uniformity.

[0029] The flow of how the dyeing equipment of the waterless dyeing system of the present invention mixes dyes and outputs them to each yarn 81 will be described in detail below with reference to FIGS. 2, 3 and 5.

[0030] First, in step S1, CMYK color model values ​​that represent the ratio of the four CMYK dyes used to create the desired color are obtained. At this time, the CMYK color model values ​​can be obtained using commercially available software such as Photoshop (registered trademark).

[0031] Next, in step S2, dye from any one of the dye storage cans 11 is poured into the dye mixing box 2 for test dyeing.

[0032] In step S3, one of the passages 53 is defined as a test passage 53' (see Figure 5), the first upstream flow path 524 corresponding to the test passage 53' is defined as a first test flow path 524', the pump means 6 corresponding to the first test flow path 524' is defined as a first test pump means 6', the temporary storage cases 62 in which CMYK color dyes are stored are defined as non-transparent dye temporary storage cases 62', and further, the temporary storage case 62 in which transparent dyes are stored is defined as a transparent dye temporary storage case 62".

[0033] In step S4, the yarn 81 to be test dyed is passed through the test passage 53' defined in step S3 at a predetermined yarn providing speed.

[0034] In step S5, the input pump 61 and output pump 65 of the first test pump means 6' defined in step S3 are opened and adjusted to maintain the dye level in the temporary storage case 62 of the first test pump means 6' at the target level and to allow the dye adsorbed into the yarn 81 to reach a saturation adsorption amount, thereby achieving uniform dyeing. At this time, the flow rate of the output pump 65 of the first test pump means 6' is defined as the test output flow rate. The saturation adsorption amount represents the maximum amount of dye that can be absorbed by a given unit length of the yarn 81 to be test dyed. If the amount of dye adsorbed to the yarn 81 to be test-dyed is below the saturation absorption amount, discontinuous dyeing will occur in the yarn 81 to be test-dyed. If the amount of dye adsorbed to the yarn 81 to be test-dyed is above the saturation absorption amount, the dye will bleed and spill onto the yarn 81 to be test-dyed. Therefore, if the amount of dye adsorbed to the yarn 81 to be test-dyed is neither too little nor too much, it can be determined that the dye adsorbed to the yarn 81 to be test-dyed has reached the saturation absorption amount. Because the saturation absorption amount of a yarn 81 varies depending on various factors, such as thickness, material, and humidity, the above process can reliably obtain the saturation absorption amount of the yarn 81. The dye flow rate required to be supplied to the target yarn 81 at a specific feed speed can be obtained.

[0035] In step S6, the input pump 61 and output pump 65 corresponding to the transparent dye temporary storage case 62" are opened to wash out the dye from each dye supply guide tube 12, the dye mixing box 2, and each dye output guide tube 54, and then the output pump 65 of the first test pump means 6' is opened to output the transparent dye to the yarn 81 to be test dyed until it is confirmed that all the dye adsorbed in step S5 has been washed out from the yarn 81 to be test dyed.

[0036] In step S7, the input pumps 61 and output pumps 65 in each dye output guide pipe 54 are closed. Then, based on the acquired CMYK color model values, the output pumps 65 and input pumps 61 corresponding to each opaque dye temporary storage case 62' are opened and adjusted, thereby maintaining the dyes in each opaque dye temporary storage case 62' at their respective target water levels, and injecting and mixing the dyes of each color into the dye mixing box 2 at a ratio corresponding to the CMYK color model values.

[0037] In step S8, the output pump 65 and input pump 61 corresponding to the transparent dye temporary storage case 62" are opened and adjusted to maintain the dye in the transparent dye temporary storage case 62" at the target water level, while confirming that the color intensity of the dye in the dye mixing box 2 matches the desired color. The flow rate of each output pump 65 corresponding to each non-transparent dye temporary storage case 62' and transparent dye temporary storage case 62" is defined as the dye mixing flow rate, and the test dyeing is completed.

[0038] In this way, the parameters of each target water level value, test output flow rate, and each dye mixing flow rate are obtained by the test dyeing from step S2 to step S8, and are stored in the control means 7.

[0039] In step S9, the input pumps 61 and output pumps 65 in each dye supply guide pipe 12 are closed. The multiple yarns 81 are passed through each passage 53 at the yarn supply speed. The dye output flow paths (first upstream flow path 524, second upstream flow path 525, first downstream flow path 514, or second downstream flow path 515) are set in the dye injection means 5. The control means 7 supplies dye in the dye mixing box 2 to each corresponding flow path based on the saturated absorption amount, and dyes each yarn 81 via each passage 53. Then, just before the dye in the dye mixing box 2 runs out, the input pumps 61 and output pumps 65 in each dye output guide pipe 54 are closed, and the process returns to step S8, where the input pumps 61 and output pumps 65 in each dye supply guide pipe 12 are opened to mix the dye again.

[0040] For each passage 53, the user can select the corresponding first upstream passage 524 and first downstream passage 514 to output dye for dyeing, or can also select the corresponding second upstream passage 525 and second downstream passage 515 to output dye through a total of four passages to achieve a more complete and uniform dyeing effect. Note that even if the number of passages selected is different, the saturation absorption amount of dye absorbed by the yarn 81 will not change, so the total flow rate of dye output from each passage must match the test output flow rate.

[0041] As another variation of this embodiment, it is also possible to define lower and upper limits for the dye water level of the dye in each temporary storage case 62, and have the control means 7 control the dye water level of the dye in each temporary storage case 62 so that it is maintained between the corresponding lower and upper limits.

[0042] Maintaining the dye in the temporary storage case 62 within the water level range determined by the lower and upper limits means that the pressure of the dye output from the temporary storage case 62 to the corresponding output pump 65 is maintained within a certain range, which allows the dye output from the temporary storage case 62 to maintain a constant pressure, keeping the flow rate of the dye output from each output pump 65 accurate and stable, and reducing pressure-related errors when supplying the dye.

[0043] Therefore, by maintaining the flow rate of dye output from each pump means 6 accurately and stably, the flow rate and ratio of dye output to the dye mixing box 2 can be accurately controlled, so that dyes of each color can be reliably mixed in a ratio corresponding to the CMYK color model value, and the amount of dye output to each yarn 81 can be controlled to keep each yarn 81 in a saturated absorption state, thereby improving the dyeing quality.

[0044] It should be noted that by changing the configuration of the dye injection means 5, the dyeing equipment of the waterless dyeing system of the present invention can be applied to different types of dyeing objects, and the same accurate color mixing and flow rate control can be achieved as the dyeing equipment of the waterless dyeing system of the present invention.

[0045] A second embodiment of the dyeing equipment for the waterless dyeing system of the present invention is shown in FIGS. 6 and 7. Referring also to FIG. 5, this second embodiment differs from the first embodiment in that two first mounting grooves 517 are formed in the first outer surface 512 of the lower base 51, and two second mounting grooves 526 are formed in the second outer surface 522 of the upper base 52. Furthermore, the dye injection means 5 in this second embodiment does not include the dye output guide tube 54 and the pump means 6 disposed therein. Instead, the dye injection means 5 in this second embodiment includes four dye injection modules 58 disposed in the first mounting grooves 517 and the second mounting grooves 526, respectively, a supply module 59 disposed between each dye injection module 58 and the dye mixing box 2, and a piezoelectric switch module (not shown) disposed in each dye injection module 58. Each dye injection module 58 is formed with a plurality of dye injection channels 581 communicating with the passage 53. In this second embodiment, by controlling the piezoelectric switch module, the dye in the dye mixing box 2 can be output to the yarn 81 in each passage 53 via the supply module 59 and each dye injection channel 581.

[0046] The dyeing facility of the waterless dyeing system of the present invention has the following advantages:

[0047] First, by temporarily storing some of the dye in the temporary storage case 62 and managing the dye level in the temporary storage case 62, it is possible to accurately control the pressure and flow rate of the dye output from the temporary storage case 62 to the dye mixing box 2 or each passage 53, even if the dye pressure in the dye supply means 1 or the dye mixing box 2 changes and the pipe lengths of each dye supply guide pipe 12 and each dye output guide pipe 54 are different. This improves the degree of dye mixing and the dyeing precision and quality of each yarn 81, and maintains the dye absorption by the yarn 81 to be dyed at the saturation absorption amount, preventing the yarn 81 from absorbing too much or too little dye, thereby improving the dyeing quality of the yarn 81.

[0048] In addition, by arranging each temporary storage case 62 upstream of the dye mixing box 2 at the same height, and by arranging each temporary storage case 62 upstream of each first upstream flow path 524 and second upstream flow path 525 at the same height, and further by arranging each temporary storage case 62 upstream of each first downstream flow path 514 and second downstream flow path 515 at the same height, the water level adjustment by each pump means 6 becomes more effective, and in particular the influence of water pressure due to the height at which each temporary storage case 62 is arranged can be eliminated, so the flow rate of dye to the first downstream flow path 514 and second downstream flow path 515 can be stably and accurately controlled and deviations are less likely to occur.

[0049] Furthermore, while the yarn 81 to be dyed is passing through each passage 53 defined between the lower base 51 and the upper base 52, dye is injected from nozzle devices 55 located above and below the yarn 81 to dye it, which reduces the effects of the yarn 81 shaking and allows the yarn 81 to be dyed so that it is immersed in the dye within the passage 53, which is an enclosed space, thereby increasing the efficiency with which the dye is absorbed into the yarn 81 and saving dye.

[0050] Furthermore, since the first upstream flow path 524, the second upstream flow path 525, the first downstream flow path 514, and the second downstream flow path 515 are all configured to extend along the vertical direction Z, the dye can be supplied to each passage 53 via each nozzle device 55 via the shortest route, thereby improving the dye supply efficiency.

[0051] Furthermore, the dye discharge passages 516 are configured to allow excess dye in the passages 53 to be discharged, thereby preventing the yarn 81 from being provided with too much dye.

[0052] Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
