Description

Technical Field

[0001] The present invention belongs to the technical field of textile printing and dyeing, and specifically relates to a method and device for solving the problem of reactive turquoise blue dye spots. Background Art

[0002] Reactive turquoise blue is a dye widely used in the chemical industry. It has bright colors and very good light fastness and heat resistance, so it is widely used in the dyeing and printing of various textiles.

[0003] Reactive turquoise blue dye spots are a common dyeing phenomenon. Usually, during the dyeing process, dye molecules react with cellulose fibers to form blue spots. These dye spots are usually caused by the uneven distribution of dye molecules during the dyeing process, resulting in higher-concentration dye spots in certain areas. The appearance of reactive turquoise blue dye spots will seriously affect the appearance and quality of the fabric and reduce its commercial value. Therefore, in the dyeing process, how to avoid the generation of reactive turquoise blue dye spots is an important research topic.

[0004] The uneven dissolution of dyes during the dyeing process is one of the important reasons for the frequent appearance of dye spots and dots. This uneven dissolution phenomenon may lead to uneven distribution of dye particles on the fabric, resulting in irregular spots and dot-like defects in the dyeing result. In order to obtain a more uniform and beautiful dyeing effect, we need to control the dye dissolution process more precisely to reduce the impact of this unevenness.

[0005] In related technologies, in order to enhance the uniformity of dye dissolution during the dyeing process, dyes are usually stirred and mixed through auxiliary equipment. For example, a device for solving the problem of uneven dissolution and dispersion of dyes during the dipping of plush fabrics is disclosed in related technologies, with the application number CN2022110141246. In this solution, a sieve layer is used to isolate and collect the precipitated pigments in the dyes inside the dye tank body, reducing the precipitation pigments from falling to the bottom of the dye tank body. At the same time, it is convenient for the reciprocating horizontal plate and the helical impeller to cooperate to reciprocally stir and blow the precipitated pigments upward, so that the dyes inside the dye tank body can be better dispersed inside the dye tank body, and thus the dyes are more evenly distributed to improve the dipping effect of the dipped plush fabrics. However, it is found in actual application that, on the one hand, under the action of gravity, the dye concentration in the dye tank shows a stepped distribution, and on the other hand, limited by the action range and strength of the stirring mechanism, the effect on the dye solution is uneven. Therefore, simple stirring and mixing has a low effect on the uniform dispersion of dyes.

[0006] In view of this, the present invention proposes a method and device for solving reactive turquoise blue dye spots to solve the above technical problems. Summary of the Invention

[0057] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0058] As Figures 1 to 9 shown, a device for solving the problem of reactive turquoise blue dye spots according to the present invention includes a dyeing bath 2, and also includes a laminar flow mixing assembly. The laminar flow mixing assembly is installed on the dyeing bath 2, and the laminar flow mixing assembly is used for layer-by-layer mixing of the dye in the dyeing bath 2.

[0059] The laminar flow mixing assembly includes an auxiliary cylinder 1, a stirring blade 21, a laminar flow pipe 22 and a circulation pump 23.

[0060] An auxiliary cylinder 1 is installed on one side of the dyeing bath 2. The auxiliary cylinder 1 is a cavity-type cylindrical structure. A temperature control system is installed inside the auxiliary cylinder 1 to control the temperature inside the auxiliary cylinder 1. A stirring blade 21 is rotatably installed inside the auxiliary cylinder 1. The stirring blade 21 is used for stirring and mixing the dye inside the auxiliary cylinder 1.

[0061] Uniformly distributed laminar flow pipes 22 are installed inside the dyeing bath 2. The laminar flow pipes 22 are evenly arranged along the depth direction of the dyeing bath 2. The surface of the laminar flow pipes 22 is evenly perforated. The laminar flow pipes 22 are divided into two groups, and the two groups of laminar flow pipes 22 are arranged alternately.

[0062] A circulation pump 23 is fixedly installed on the dyeing bath 2. The input end of the circulation pump 23 is conductively connected to one group of laminar flow pipes 22, and the other group of laminar flow pipes 22 is directly connected to the auxiliary cylinder 1 through a conducting pipe 24.

[0063] During the dyeing process of reactive turquoise blue dye, in order to prevent the dye from stratifying and dissolving unevenly in the dyeing bath 2, by mechanically stirring and temperature controlling the dye solution, the dissolution uniformity of the dye can be effectively improved. And in order to enhance the convenience of the dye dispersion in the dyeing solution, the present invention sets a laminar flow mixing assembly, and by layer-by-layer extraction and layer-by-layer discharge of the dyeing solution in the dyeing bath 2, the dissolution and dispersion uniformity degree of the dye in the dyeing bath 2 is enhanced, and the generation probability of dye spots and dye dots is reduced.

[0064] Specifically, when preparing for dyeing, according to the dyeing process ratio, equal - proportion clear water is put into the dyeing pool 2. Subsequently, the laminar flow mixing component is started, and the dye is injected into the dyeing pool 2 at a constant speed. Since the laminar flow pipes 22 installed in the dyeing pool 2 are evenly divided into two groups and the two groups of laminar flow pipes 22 are arranged alternately, when the circulation pump 23 is started, negative pressure is generated in the laminar flow pipes 22 that are conductively connected to the input end of the circulation pump 23. As a result, the clear water and dye in the dyeing pool 2 are injected into the auxiliary cylinder 1 along the laminar flow pipes 22 and the circulation pump 23. At the same time, the stirring blades 21 installed in the auxiliary cylinder 1 rotate. In the present invention, the stirring blades 21 are equipped with their own driving motors and stir and mix the solution in the auxiliary cylinder 1 by rotating and stirring. Then, the mixed dye solution enters the conduction pipe 24 and flows back to the dyeing pool 2 through another group of laminar flow pipes 22 that are conductively connected to the conduction pipe 24, thereby realizing the cyclic stirring and mixing of the dye solution and enhancing the uniformity of dye dissolution in the dyeing pool 2.

[0065] By setting the laminar flow mixing component, on the one hand, the dye solution is pumped out of the dyeing cylinder for stirring and mixing. During the dyeing process, compared with directly mixing in the dyeing pool 2, pumping it into the auxiliary cylinder 1 for mixing can avoid the influence of fabrics and mechanical equipment on dye mixing, and enhance the convenience of dye and dye solution stirring and mixing. On the other hand, by setting the laminar flow pipes 22, the extraction and discharge range of the dye and dye solution is increased and the uniformity is enhanced. Therefore, in the actual application process, the uniformity of dye dissolution in the dyeing pool 2 can be enhanced.

[0066] As a preferred embodiment of the present invention, the auxiliary cylinder 1 is composed of an inner cylinder 11 and an outer cylinder 12 sleeved. A return cavity 13 is formed between the inner cylinder 11 and the outer cylinder 12. The temperature control system and the stirring blades 21 are both installed in the inner cylinder 11, and the top of the inner cylinder 11 is conductively connected to the return cavity 13.

[0067] The bottom of the inner cylinder 11 is designed in a conical shape. A slag - collecting bottle 3 is detachably installed at the bottom of the auxiliary cylinder 1, and a filter screen 31 is fixedly installed at the conduction part between the inner cylinder 11 and the return cavity 13.

[0068] During the cyclic stirring of the dye and dye solution, the extracted dye solution is discharged into the inner cylinder 11 and continuously stirred and mixed by the stirring blades 21. As the liquid level of the dye solution in the inner cylinder 11 continues to rise, the mixed dye solution flows into the return cavity 13 and then flows into the conduction pipe 24. During this process, the flow path of the dye solution in the auxiliary cylinder 1 increases, resulting in uniform mixing of the dye solution. Moreover, when the stirring blades 21 stir the dye solution in the inner cylinder 11, the dye solution in the inner cylinder 11 rotates directionally. Limited by the shape of the inner cylinder 11, finally, the solid impurities in the dye solution move towards the slag - collecting bottle 3 under the action of centrifugal force and gravity. The setting of the filter screen 31 further enhances the separation effect of the dye solution and the solid impurities, enabling the dye solution to be filtered and purified during the circulation process, thereby improving the dyeing quality of the fabric.

[0069] As a preferred embodiment of the present invention, a telescopic frame 4 is installed in the dyeing tank 2. The telescopic frame 4 is an annular structure, and the telescopic frame 4 is a frame structure made of multiple telescopic rods with adjustable length and width. The telescopic frame 4 matches the dyeing tank 2. An electric telescopic rod 41 is installed on the dyeing tank 2, and the output end of the electric telescopic rod 41 is connected to the telescopic frame 4. The electric telescopic rod 41 is used to adjust the volume of the telescopic frame 4. An extension pipe 42 is fixedly installed on the laminar flow pipe 22 directly connected to the auxiliary cylinder 1, and the extension pipes 42 all extend to the telescopic frame 4.

[0070] A booster pump 25 is fixedly installed in the middle of the conduction pipe 24. The booster pump 25 is electrically connected to the electric telescopic rod 41 through a control system. When the length of the electric telescopic rod 41 increases, the power of the booster pump 25 decreases.

[0071] During fabric dyeing, due to limitations such as the quantity of fabric in a single dyeing and the dyeing process, the required dyeing space is inconsistent during the fabric dyeing process. In order to enhance the dissolution uniformity of the dye in the dye liquor contacted by the fabric, by setting the telescopic frame 4 and installing the extension pipes 42 installed on the laminar flow pipe 22 for reflux on the telescopic frame 4. During specific installation, the ends of the extension pipes 42 are slidably installed on the telescopic frame 4, and adjacent extension pipes 42 are separated by springs. Therefore, during the process of adjusting the size of the telescopic frame 4, the distance between the extension pipes 42 can be automatically adjusted. After the dyeing process is determined, by adjusting the length of the electric telescopic rod 41, the size of the telescopic frame 4 can be adjusted. When the size of the telescopic frame 4 is fixed, the dye liquor in the reflux chamber 13 flows into the conduction pipe 24, is pumped by the booster pump 25 to the laminar flow pipe 22 and the extension pipes 42, and finally sprays into the chamber surrounded by the telescopic frame 4. According to the size of the chamber surrounded by the telescopic frame 4, under the control of a predetermined program, the power of the booster pump 25 is adjusted. When the size of the telescopic frame 4 is larger, the volume of the chamber it surrounds is large, so a higher power of the booster pump 25 is required, the pressure of the dye liquor ejected from the extension pipe 42 is large, and the movement distance of the dye liquor in the chamber of the telescopic frame 4 is large. On the contrary, the power of the booster pump 25 is reduced to reduce the ejection force of the dye liquor, thereby ensuring the flow mixing effect of the dye liquor in the chamber of the telescopic frame 4.

[0072] The present invention sets the telescopic frame 4, dyes the fabric in the chamber surrounded by the telescopic frame 4, and directly sprays the stirred and mixed dye liquor into the chamber surrounded by the telescopic frame 4, and then diffuses it into the dyeing tank 2. Thus, during the process of uniformly mixing the dye liquor in the dyeing tank 2, the components of the dye liquor in the telescopic frame 4 are first processed, further reducing the probability of dye spots and stains.

[0073] As a preferred embodiment of the present invention, it further includes an intelligent distribution component, which is installed on the dyeing tank 2 and the laminar flow mixing component, and the intelligent distribution component adjusts the circulation rate according to the stratified concentration of the dye;

[0074] The intelligent distribution component includes a detection probe 5 and an electromagnetic regulating valve 51;

[0075] The detection probe 5 is evenly installed in the dyeing tank 2, and the detection probe 5 is arranged along the depth direction of the dyeing tank 2, and the detection probe 5 is used to detect the components of the dyeing solution;

[0076] The electromagnetic regulating valve 51 is installed on the laminar flow pipe 22, and the laminar flow pipe 22 is connected to the circulation pump 23 or the conduction pipe 24 through the electromagnetic regulating valve 51.

[0077] When actually extracting the dyeing solution in the dyeing tank 2 for mixing, by detecting the components of the dyeing solution at each depth in the dyeing tank 2, and then under the control of a preset program, adjusting the opening degree of the corresponding electromagnetic regulating valve 51, that is, for the depth layer with a large difference in concentration content compared to the standard concentration, the opening degree of the corresponding electromagnetic regulating valve 51 is large, and the extraction rate of the dyeing solution is fast, while for the depth layer with the dyeing solution concentration close to the standard concentration, the opening degree of the corresponding electromagnetic regulating valve 51 is small and the extraction rate of the dyeing solution is slow, so as to selectively extract the dyeing solution. At the same time, because the mixed dyeing solution has a high degree of uniformity, discharging it to the layer with a large difference from the standard can effectively accelerate the rate of mixing the dyeing solution evenly, resulting in a faster rate of adjusting the dye concentration in each depth layer of the dyeing tank 2.

[0078] A test tube 52 is fixedly installed on the outer wall of the dyeing tank 2, and the test tube 52 is connected to the dyeing tank 2 in a conducting manner. The test tubes 52 are evenly arranged along the depth direction of the dyeing tank 2. A group of laminar flow pipes 22 corresponding to the circulation pump 23 are connected to the test tube 52 in a conducting manner, and the laminar flow pipe 22 is located between the electromagnetic regulating valve 51 and the laminar flow pipe 22.

[0079] The test tube 52 is made of a transparent material.

[0080] The setting of the test tube 52, on the one hand, reduces the influence of fabrics and mechanical equipment when detecting the dyeing solution. On the other hand, since the test tube 52 is located on the dyeing solution extraction path, it enhances the accuracy of detecting the concentration of the dyeing solution at each depth layer of the dyeing tank 2. And the test tube 52 made of a transparent material is convenient for external staff to visually judge the concentration of the dyeing solution at each depth layer.
