Description

Discontinuous pattern dyeing technique {DYEING METHOD OF DISCONTINUOUS PATTERN}

The present invention relates to a kind of dyeing technique, and more particularly to a dyeing technique providing a discontinuous pattern.

In the field of fabric dyeing, the dyeing method used for man-made fibers such as polyamides ((Polyamide, PA), etc.) usually involves an additive treatment process by adding an acid, and through this, the pH value of the dyeing solution is changed to change the pH value of artificial fibers and acid dyes. It completes the bonds between molecules, and it also includes various manufacturing processes such as heating, color development, washing, and color fixing.

Currently, the dyeing method commonly used in the rope dyeing machine has a relatively low variability of the product because the color shade of the finished product is mostly uniform and the pattern is fixed. If a product with irregular or discontinuous patterns is required, an inkjet printer must be used. However, the conventional inkjet printing press requires several workbenches in the production process, consumes a lot of manpower, and takes a very long time to work. In addition, due to the use of artificially designed discontinuous patterns, overlapping patterns inevitably appeared when dyeing long fabrics exceeding a certain length through ink jet printing. Existing dyeing techniques have the above disadvantages.

The dyeing machine rotates the fabric waiting to be dyed within 1 to 2 times the time of the first period, and as a result, the dyeing solution jet nozzle sprays the dyeing solution for the entire length of the fabric waiting to be dyed. The height of the liquid side of the dyeing solution in the dyeing machine is gradually increased. In addition, the dyeing technique includes the following second procedure. The temperature in the dyeing machine is raised from the first temperature to the second temperature. Also, the dyeing technique includes a third order. The temperature in the dyeing machine is maintained at the second temperature to form the fabric waiting to be dyed into the dyed fabric. Among them, the fabric waiting to be dyed in the period of the first sequence is formed of a wavy intermediate product, and in the period of the second sequence, the temperature rises to change the pressure in the dyeing machine, so a part of the intermediate product is It rises above the liquid surface, and after the second sequence is completed, a part of the intermediate product is on the liquid surface of the dyeing solution, and the other part of the intermediate product remains immersed in the dyeing solution, Through this process, the chromosome cloth of the intermediate product after the third sequence is completed can have a discontinuous pattern.

Figure 2 is a perspective view showing the structure of a rope dyeing machine according to another embodiment of the present invention.
3 is a flowchart of a dyeing method of one embodiment of the present invention.

In order to more clearly explain the object, effect, and structural features of the present invention, the following will be described with reference to relatively excellent embodiments and drawings, and the scope of application of the present invention is not limited thereto.

Also, for example, "beneath", "... under”, “lower”, “… In the case of spatial relativity terms such as “above” and “upper”, it is used to more easily describe the relationship between elements or features in the drawing. Not only that, but it also includes the different directions required for the use or manipulation of the component.

1 is a perspective view showing the structure of a rope dyeing machine as relates to one embodiment of the present invention. Referring to FIG. 1 , the first rope dyeing machine 100 has a body 110 , a fabric storage space 120 , a cloth entrance 130 , a cloth guide wheel 140 , and a dye spray nozzle 150 . ) is included. Here, after the cloth (C) waiting to be dyed enters the cloth storage space 120 through the cloth doorway 130, it is connected to the cloth guide wheel 140 and is affected by the cloth guide wheel 140. When the first rope dyeing machine 100 starts to rotate through this, the fabric (C) waiting for dyeing is pulled by the rotational force of the fabric guide wheel 140 for a specific period (unit is seconds/times) is rotated, and it can be seen that the specific cycle is defined as the time in which the entire length of the fabric (C) waiting for dyeing passes through the dyeing solution injection nozzle 150 once.

The first rope dyeing machine 100 further includes a dyeing solution supply device 210 , a heat exchange device 220 , and a pump 230 . Here, a specific volume of the dye solution (L) is injected into the dye solution supply device 210 through the pump 230, and further transported to the heat exchange device 220 to control the temperature, and then the dye solution injection nozzle It is injected into the corresponding fabric storage space 120 through 150 . As a result, when the first rope dyeing machine 100 starts to rotate and the fabric (C) on standby for dyeing rotates at a specific cycle, the entire length of the fabric (C) on standby for dyeing contains the dyeing solution within a specific time. (L) is sprayed and applied, and the sprayed dye solution (L) is accumulated in the fabric storage space 120 and the liquid level of the dye solution (L) in the fabric storage space 120 gradually rises. it can be seen that In addition, a portion of the fabric (C) waiting for dyeing is left locked in the dyeing solution (L) in the fabric storage space 120 to form a wave shape.

In addition, according to common knowledge in the technical field to which the present invention belongs, the dyeing solution supply device 210 may be connected to each other in a non-limiting form together with the dye injection device and the acid solution injection device, and furthermore, the specific dye and the specific acid The liquid may be introduced into the path through which the dyeing liquid (L) is circulated. Here, the dye injection device and the acid solution injection device may be electrically connected to the control circuit, and furthermore, parameters such as the capacity and power at which the user injects the specific dye and the specific acid solution into the dye solution (L). It can be seen that it is also possible to set

In another implementation method of the present invention, the body 110 may be formed of a sphere or a columnar body, and the scope of the present invention is not limited thereto. The installation position of the dyeing solution injection nozzle 150 and the volume of the corresponding dyeing solution (L) can be adjusted as needed by a person skilled in the art to which the present invention belongs.

2 is a perspective view showing the structure of a rope dyeing machine as relates to another embodiment of the present invention. Referring to the contents of Figure 2, the second rope-type dyeing machine 30 includes a main body 300, and a storage area 301 is installed in the main body 300, so that the dye solution (L) and The fabric (C) waiting to be dyed is stored. A tension pipe 302 and a compression pipe 303 are also installed in the barrel body 300, and are used to transport the fabric C and the dye solution L waiting for the dyeing.

Continuing to refer to Figure 2, the cloth guide wheel 310 is installed in the barrel body 300 and is used to pull the fabric (C) waiting for the dyeing, and in the barrel body 300 also The dyeing solution injection nozzle 320 is installed and used to inject the dyeing solution (L).

2, when the user puts the cloth (C) waiting to be dyed of a certain length into the main body 300 and connects it with the corresponding cloth guide wheel 310, and the cloth guide wheel 310 rotates By towing the fabric (C) waiting to be dyed, the fabric (C) waiting to be dyed can be rotated at a specific cycle (unit: seconds/time) set by the user, and the specific cycle is It can be seen that the total length of C) is defined as the time passed through the dye spray nozzle 320 once. In addition, the dyeing solution (L) may be injected into the dyeing solution spray nozzle 320, and the dyeing solution (L) is sprayed onto the fabric (C) waiting for the dyeing and flows toward the corresponding tension pipe (302). It goes, and at this time, it has a flow velocity. The flow rate of the dyeing solution (L) in the tension pipe 302 is greater than the moving speed of the fabric (C) waiting for dyeing, and thus the fabric (C) waiting for dyeing is pulled. When the fabric (C) waiting to be dyed and the dye solution (L) are transferred to the inside of the compression pipe 303, the flow rate of the dye solution (L) is lowered, and thereby the fabric (C) waiting for dyeing This is compressed to show a wavy shape. In addition to this, the dyeing solution L is accumulated in the storage area 301 to have a liquid level. It should be noted here that the liquid surface height of the corresponding dyeing solution L shown in FIG. 1 is displayed for reference only, and is not a numerical value or ratio of the actual height. The cloth (C) waiting for dyeing is immersed in the dyeing solution (L), and through this, it can be seen that the fabric (C) waiting for dyeing is compressed and shows a wavy shape.

In addition to this, a device related to supplying a dyeing solution is installed in the second rope dyeing machine 30 to control the composition or ratio of the dyeing solution, and a temperature control system is also installed in the second rope dyeing machine to adjust the dyeing solution ( L) and it can be seen that the temperature in the main body 300 can be adjusted. All of the above-described devices can be changed within a reasonable range by a person skilled in the art to which the present invention pertains.

In addition, the actual installation position of the dyeing solution injection nozzle 320 may be different depending on different types of dyeing machines based on the user's operation method.

Among some embodiments of the present invention, the dyeing solution (L) may include water, a leveling agent, an acid solution, a dye, and the like. Specifically, the dye may be an acid dye or a dispersible dye, and the dyeing solution (L) has a specific pH value, and the specific pH value is 3 to 9.

Among some implementation methods of the present invention, the cloth (C) waiting for dyeing is made of polyester (Polyester, PE), polyamide (PA), cationic dyeable polyester (CDP), and the like.

Most of the craft processes of the dyeing technique based on the implementation method of this description include dyeing, drying, shaping, and the like. Among them, the dyeing process is carried out in a rope dyeing machine, and the rope dyeing machine may reasonably be the corresponding first rope dyeing machine 100 of FIG. 1 or the corresponding second rope dyeing machine 30 of FIG. 2 . To put it concretely, the fabric waiting to be dyed is put into the rope dyeing machine and then dyed using a specific volume of dyeing solution. It should be noted here that the fabric waiting to be dyed has a specific length and corresponding area, and the parameters are not limited to the numerical values used in this description and are adjusted according to common knowledge or needs in the technical field to which the present invention belongs. This is possible.

Figure 3 relates to the sequence of the dyeing method based on the embodiment of the present invention. Referring to the contents of Figures 1 to 3, it can be seen that the dyeing process further includes several sequences, among which the dyeing process The process includes steps S1, S2, S3, S4, and S5.

In step S1, the rope-type dyeing machine is adjusted to provide a first rotation cycle for the fabric waiting to be dyed. It means that the dye is passed through the spray nozzle of Within the execution period of 1 to 2 times the first period, the rope dyeing machine sprays and applies the dyeing solution onto the fabric waiting to be dyed using the dye spray nozzle, and also the liquid of the dyeing solution in the rope dyeing machine. The height of the surface gradually increases. It should be noted here that the liquid level of the dyeing solution within the period S1 does not exceed 2/3 of the height of the accommodation space in the dyeing machine, and the accommodation space is the fabric storage space 120 shown in FIG. 1 or FIG. 2 It can be seen that the storage area 301 indicated in . In addition, the part of the fabric waiting to be dyed within the period S1 is formed into a wavy intermediate product under pressure. state, and only a small portion of it rises above the liquid surface of the dyeing solution under pressure.

According to a relatively good practice, the dyeing solution has a specific pH value, and the pH value is a value adjusted according to the characteristics of the dye contained in the dyeing solution. It is possible to provide an optimal environment in which a connection can be formed between the fabric fibers. In addition, the first period is at least 100 seconds, and the rotation period is at least 100 seconds/wheel. Therefore, to explain further, the execution time of the sequence S1 is at least 100 seconds, and a relatively good example is between 100 seconds and 200 seconds.

In step S2, the temperature in the rope-type dyeing machine rises to increase the dyeing solution from the first temperature to the second temperature, and the first temperature is within the room temperature range of about 20-50°C, and the second temperature is about 80 It is in the range of ~135°C. The execution time of step S2 is 5 to 10 times that of the first period. Specifically, in the process of step S2, the rope dyeing machine provides heating power to raise the first temperature to the second temperature, and the heating The power is 5 to 14° C./min. A pressure change can be generated in the sealed accommodation space through the heating power, and further, a part of the intermediate product in the accommodation space gradually rises and rises above the liquid surface of the dyeing solution. More specifically, after step S2 is completed, a part of the intermediate product is placed on the liquid side of the dyeing solution, and the other part is immersed in the dyeing solution. Furthermore, it is possible to achieve the effect of having an irregular or discontinuous transition pattern within a specific area after all sequences are completed.

According to a relatively good practice, the first period is at least 100 seconds, and the rotation period is at least 100 seconds/wheel. Therefore, to explain further, the execution time of the procedure S2 does not exceed 1000 seconds, and an example of a relatively good case is between 500 seconds and 1000 seconds.

Among some implementation methods, in the process S2, the rope dyeing machine stops rotating, and for this reason, the fabric waiting to be dyed is left in a stopped state.

In step S3, the temperature in the rope dyeing machine is maintained at the second temperature to achieve a warming effect, and furthermore, the fabric waiting to be dyed after step S3 is completed is the dyed fabric. It is said that the dyed fabric formed after S3 is completed has a discontinuous pattern. The execution time of step S3 is 40 to 60 minutes, and the second temperature is 80 to 135°C according to the implementation method of this description.

Specifically, during the execution period of step S3, the rope dyeing machine provides the corresponding rotation cycle. Then, in step S3 of the other implementation methods, the rope dyeing machine may not provide any rotation cycle, that is, the fabric waiting to be dyed is left in a stopped state.

In step S4, the dyed fabric that has completed step S3 is washed at a specific temperature. And in step S5, a fixing agent is put in the rope type dyeing machine and a coloring operation is performed on the dyed fabric. At this time, the fixing agent component can be changed to a different fixing agent according to the material of the fabric. A special point to note here is that after completing step S5, at least one washing operation can be performed as needed, and then the dyed fabric can be taken out.

Specifically, after completing the dyeing of the dyed fabric, a drying process step may be entered, and the remaining moisture in the dyed fabric may be removed using a dryer. Then, the shaping process is performed on the dyed fabric at high temperature, and further, the size, color and degree of shrinkage of the dyed fabric are stabilized to obtain a finished product.

The above description establishes different features of the target provided for different embodiments or examples, and these specific embodiments or examples of the present invention in no way limit the scope of the present invention thereto. Any additions or modifications made within the scope of the application of the present invention fall within the scope of the present invention.
