Description

Technical Field

[0001] This utility model belongs to the technical field of fabric dyeing equipment, and relates to a dyeing device for high-end clothing fabrics. Background Technology

[0002] In current garment dyeing equipment, the dye liquor cannot flow sufficiently during the dyeing process, easily leading to dye sedimentation. This results in uneven contact between different parts of the fabric and the dye liquor, causing problems such as uneven dyeing, color variations, and color differences. Therefore, some solutions propose introducing mechanical stirring equipment into the dyeing tank to improve the fluidity of the dye. However, this method of introducing mechanical stirring has the following drawbacks: 1. The internal structure of the dyeing equipment is relatively complex, leaving limited space for mechanical stirring; 2. Even after installing mechanical stirring equipment, it can only improve the uniform mixing effect of the dye liquor to a certain extent, and there are still areas that cannot be stirred, failing to effectively prevent dye sedimentation; 3. Mechanical stirring inevitably creates certain mechanical forces between the dye liquor and the fabric, easily causing excessive friction, stretching, and other mechanical damage to the fabric, affecting the final quality of the fabric. This damage is particularly noticeable for lightweight, soft, high-end fabrics such as silk. The dyeing device for textile fabric production provided by the company's previous patent 2021222043090 mainly optimizes and improves the dyeing equipment from the perspective of gas purification. Similarly, it does not consider any issues such as improving the dyeing efficiency and uniformity of specific fabrics.

[0003] Therefore, it is particularly important to improve the uniformity of dyeing and accelerate the dyeing process without damaging the fabric. This utility model is proposed based on this principle. Utility Model Content

[0004] The purpose of this invention is to provide a dyeing device for high-end clothing fabrics, so as to improve the dyeing quality and efficiency of easily damaged high-end clothing fabrics.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A dyeing apparatus for high-end garment fabrics, comprising:

[0007] A dyeing chamber, used to provide a dyeing space filled with dye solution;

[0008] A heating component is located at the bottom of the dyeing chamber and is used to heat and keep the dye solution warm.

[0009] An airflow stirring assembly is disposed in the lower region of the dyeing space and is used to provide a flow of air bubbles that agitate the dye solution;

[0010] A dyeing solution circulation assembly includes a dyeing solution circulation pipeline, wherein the inlet end of the dyeing solution circulation pipeline is connected to the upper region of the dyeing space, and the outlet end is connected to the top of the airflow stirring assembly.

[0011] A roller drive assembly is used to guide the fabric through the dyeing space and complete the dyeing operation.

[0012] Furthermore, the heating assembly includes a heat-conducting plate located in the area of ​​the bottom of the dyeing space, and an electric heating element connected to the heat-conducting plate.

[0013] Furthermore, the airflow stirring assembly includes a gas source unit, a gas delivery pipeline, and a gas distributor connected in sequence, with airflow openings distributed on the gas distributor.

[0014] Furthermore, the airflow opening adopts a combination of downward airflow, upward airflow, and side airflow.

[0015] Furthermore, the vertical distance between the gas distributor and the bottom of the dyeing space is no more than 10cm.

[0016] Furthermore, the dye liquor circulation assembly also includes a liquid distributor located above the airflow stirring assembly, and the liquid distributor is connected to the outlet end of the dye liquor circulation pipeline.

[0017] Furthermore, a circulation pump is also installed on the dye liquor circulation pipeline.

[0018] Furthermore, the inlet of the dye liquor circulation pipeline is positioned such that the fabric entering the dyeing box passes through the dyeing space from below the inlet of the dyeing circulation pipeline.

[0019] Furthermore, the roller drive assembly includes a first guide roller, a second guide roller, and a third guide roller arranged sequentially along the fabric travel direction, wherein,

[0020] The first guide roller is located at the fabric inlet of the dyeing box and is used to guide the fabric into the dyeing space.

[0021] The third guide roller is located at the fabric outlet of the dyeing box and is used to guide the dyed fabric out of the dyeing space.

[0022] The second guide roller is used to guide the fabric within the dyeing space.

[0023] Furthermore, the second guide roller is provided in several units, and is arranged alternately in a "high and low" manner.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] (1) By setting up an airflow stirring component in the dyeing box, the gas bubble flow is introduced to disturb the dye liquor, which can improve the uniformity of the dye liquor distribution. At the same time, compared with the traditional mechanical stirring component, the introduced airflow stirring component occupies less internal space in the dyeing box, reducing the mechanical stress on the fabric. It is especially suitable for dyeing high-end fabrics such as silk fabrics that are easily damaged, thin, soft and soft.

[0026] (2) As the fabric moves through the dyeing space, it inevitably divides the dye liquor into two parts, the lower part of the fabric and the upper part of the dye liquor are well disturbed by the air bubble flow, and the dye liquor distribution is uniform and sufficient. However, the upper part of the fabric is basically static and the dye liquor is prone to settling. Therefore, by introducing a dye liquor circulation component, the circulation flow of the dye liquor in the upper and lower parts of the dyeing space can be enhanced, the uniformity of dye distribution and temperature distribution in the entire dyeing space can be improved, and the dyeing uniformity and color fastness can be improved.

[0027] (3) The airflow generated by the airflow stirring component can allow dye molecules to penetrate deeper into the fabric fibers and combine with active groups such as amino groups on the fabric fibers such as silk fibers, effectively improving the color fastness of the fabric.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0033] Unless otherwise specified, the functional components or structures in the following embodiments or examples are conventional components or structures used in the art to achieve the corresponding functions.

[0034] To improve the dyeing quality and efficiency of easily damaged high-end garment fabrics, this utility model provides a dyeing device for high-end garment fabrics, comprising:

[0035] Dyeing chamber 1, used to provide a dyeing space filled with dye solution;

[0036] A heating component is disposed at the bottom of the dyeing chamber 1 and is used to heat and keep the dye solution warm;

[0037] An airflow stirring assembly is disposed in the lower region of the dyeing space and is used to provide a flow of air bubbles that agitate the dye solution;

[0038] The dyeing solution circulation assembly includes a dyeing solution circulation pipeline 7, the inlet end of which is connected to the upper region of the dyeing space, and the outlet end of which is connected to the top of the airflow stirring assembly.

[0039] A roller drive assembly is used to guide the fabric through the dyeing space and complete the dyeing operation.

[0040] After pretreatment and other processes, the fabric to be dyed is fed into the dyeing space via a roller drive assembly. Under the immersion of the dye liquor, the fabric is dyed. During the dyeing process, the heating assembly maintains the dye liquor in the dyeing space within a suitable dyeing temperature range. The airflow stirring assembly generates a bubble flow, which, together with the dye liquor circulation assembly, circulates the dye liquor in the upper and lower parts of the dyeing space. This improves the uniformity of the dye liquor distribution and allows the dye molecules to penetrate deeper into the fabric fibers under the action of the bubbles, thereby improving the color fastness and uniformity, especially the uniformity of one side of the fabric surface.

[0041] In some specific embodiments, the heating assembly includes a heat-conducting plate 3 located in contact with the bottom region of the dyeing space, and an electric heating element 2 connected to the heat-conducting plate 3. The function of the heat-conducting plate 3 is to distribute the heat generated by the electric heating element 2 more quickly and evenly to the dye liquor in the bottom region of the dyeing space, improving the heating and uniformity effects. Furthermore, to improve the stability of temperature control, a temperature sensor can be introduced to detect the dye liquor temperature, and a matching PLC controller can be used to provide feedback and adjust the electric heating element 2 to maintain the dye liquor temperature within a set reasonable temperature range. This heating control process is conventional technology in the art and will not be described in detail here.

[0042] In some specific embodiments, the airflow mixing assembly includes a gas source unit, a gas delivery pipeline, and a gas distributor 4 connected in sequence, wherein the gas distributor 4 has airflow openings 11 distributed on it. The gas source unit can be a blower, air compressor, or other commonly used devices in the art. The distribution density of the airflow openings 11 is adjusted according to the specifications and dimensions of the dyeing chamber 1 and the gas distributor 4, as long as it can sufficiently achieve the mixing effect.

[0043] In a more specific embodiment, the airflow opening 11 adopts a combination of downward airflow, upward airflow, and side airflow. In addition to the traditional upward airflow, the introduction of the combination of downward and side airflow can ensure that the generated bubble flow fully agitates the dead corner areas of the dyeing space, effectively preventing dye sedimentation.

[0044] In a more specific embodiment, the pore size of the airflow opening 11 is micro-nano size, which can easily generate micro-nano bubbles and promote the penetration of dye into the fabric fibers.

[0045] In a more specific embodiment, the vertical distance between the gas distributor 4 and the bottom of the dyeing space is no more than 10cm, so that the stirring effect on the bottom area can be taken into account at the same time.

[0046] In some specific embodiments, the dye liquor circulation assembly further includes a liquid distributor 5 located above the airflow stirring assembly. The liquid distributor 5 is connected to the outlet end of the dye liquor circulation pipeline. The dye liquor circulation assembly can circulate the dye liquor with poor flowability above the dyed fabric back to the bottom and quickly and evenly disperse it under the action of the bubble flow, thereby improving the dyeing uniformity.

[0047] In a more specific embodiment, the dye liquor circulation pipeline 7 is also equipped with a circulation pump 6.

[0048] In some specific embodiments, the inlet of the dye liquor circulation pipe 7 is positioned such that the fabric entering the dyeing box 1 passes through the dyeing space below the inlet of the dyeing circulation pipe, thereby ensuring that the dye liquor in the upper region with poor flowability can be circulated.

[0049] In some specific embodiments, the roller drive assembly includes a first guide roller 8, a second guide roller 9, and a third guide roller 10 arranged sequentially along the fabric travel direction, wherein,

[0050] The first guide roller 8 is located at the fabric inlet of the dyeing box 1 and is used to guide the fabric into the dyeing space.

[0051] The third guide roller 10 is located at the fabric outlet of the dyeing box 1 and is used to guide the dyed fabric out of the dyeing space.

[0052] The second guide roller 9 is used to guide the fabric to move within the dyeing space.

[0053] The roller drive assembly described above can effectively increase the travel of the fabric in the dyeing space, make full use of the space of the dyeing box 1, increase the residence time of the fabric in the dyeing area, and thus improve the dyeing effect.

[0054] In a more specific embodiment, the second guide roller 9 is provided in several units and is arranged alternately in a "high and low" manner.

[0055] Each of the above implementation methods can be implemented individually, or in any combination of two or more.

[0056] The above implementation methods will be described in more detail below with reference to specific embodiments.

[0057] Example 1:

[0058] To improve the dyeing quality and efficiency of easily damaged high-end garment fabrics, this utility model provides a dyeing device for high-end garment fabrics, comprising:

[0059] Dyeing chamber 1, used to provide a dyeing space filled with dye solution;

[0060] A heating component is disposed at the bottom of the dyeing chamber 1 and is used to heat and keep the dye solution warm;

[0061] An airflow stirring assembly is disposed in the lower region of the dyeing space and is used to provide a flow of air bubbles that agitate the dye solution;

[0062] The dyeing solution circulation assembly includes a dyeing solution circulation pipeline 7, the inlet end of which is connected to the upper region of the dyeing space, and the outlet end of which is connected to the top of the airflow stirring assembly.

[0063] A roller drive assembly is used to guide the fabric through the dyeing space and complete the dyeing operation.

[0064] Please see again. Figure 1As shown, the heating assembly includes a heat-conducting plate 3 located in contact with the bottom area of ​​the dyeing space, and an electric heating element 2 connected to the heat-conducting plate 3. The function of the heat-conducting plate 3 is to distribute the heat generated by the electric heating element 2 more quickly and evenly to the dye liquor in the bottom area of ​​the dyeing space, improving the heating and uniformity effects. Furthermore, to improve the stability of temperature control, a temperature sensor can be introduced to detect the dye liquor temperature, and a matching PLC controller can be used to adjust the electric heating element 2 to maintain the dye liquor temperature within a set reasonable temperature range. This heating control process is conventional technology in the field and will not be described in detail here.

[0065] Please see again. Figure 1 As shown, the airflow stirring assembly includes a gas source unit, a gas delivery pipeline, and a gas distributor 4 connected in sequence. The gas distributor 4 has airflow openings 11 distributed on it. The gas source unit can be a blower, air compressor, or similar device commonly used in the art; the gas distributor 4 can be a ring-shaped gas distributor 4 commonly used in the art. The distribution density of the airflow openings 11 is adjusted according to the specifications and dimensions of the dyeing chamber 1 and the gas distributor 4, as long as it can sufficiently achieve the stirring effect. In this embodiment, the airflow openings 11 adopt a combination of downward, upward, and side-direction airflow. Introducing a combination of downward and side-direction airflow, while maintaining the traditional upward airflow, allows the generated bubble flow to fully agitate the dead zones of the dyeing space, effectively preventing dye sedimentation. Furthermore, the pore size of the airflow openings 11 is micro-nano, which facilitates the generation of micro-nano bubbles, promoting the penetration of dye into the fabric fibers. The gas distributor 4 is at a vertical distance of no more than 10cm from the bottom of the dyeing space, so that the stirring effect on the bottom area can be taken into account at the same time.

[0066] Please see again. Figure 1 As shown, the dye liquor circulation assembly also includes a liquid distributor 5 located above the airflow stirring assembly. The liquid distributor 5 is connected to the outlet end of the dye liquor circulation pipeline. The dye liquor circulation assembly can circulate the less fluid dye liquor above the dyed fabric back to the bottom, and under the action of the bubble flow, quickly and evenly disperse it, improving dyeing uniformity. A circulation pump 6 is also provided on the dye liquor circulation pipeline 7. The inlet end of the dye liquor circulation pipeline is positioned such that the fabric entering the dyeing chamber 1 passes below the inlet end of the dyeing circulation pipeline through the dyeing space, thereby ensuring directional circulation of the less fluid dye liquor in the upper area. Furthermore, the liquid outlet direction of the liquid distributor 5 is preferentially downwards to quickly mix with the rising bubble flow, improving the uniform mixing effect of the dye liquor. The liquid distributor 5 can be of the type commonly used in the art, such as a porous tubular liquid distributor 5 or a disc-type liquid distributor 5.

[0067] Please see again. Figure 1 As shown, the roller drive assembly includes a first guide roller 8, a second guide roller 9, and a third guide roller 10 arranged sequentially along the fabric travel direction, wherein...

[0068] The first guide roller 8 is located at the fabric inlet of the dyeing box 1 and is used to guide the fabric into the dyeing space.

[0069] The third guide roller 10 is located at the fabric outlet of the dyeing box 1 and is used to guide the dyed fabric out of the dyeing space.

[0070] The second guide roller 9 is used to guide the fabric to move within the dyeing space.

[0071] The aforementioned roller drive assembly can effectively increase the travel distance of the fabric within the dyeing space, fully utilize the space of the dyeing chamber 1, and increase the residence time of the fabric in the dyeing area, thereby improving the dyeing effect. Several second guide rollers 9 are provided, arranged in an alternating pattern of "one high, one low." The fabric passes around three second guide rollers 9 and travels within the dyeing space along a predetermined travel path.

[0072] After pretreatment and other processes, the fabric to be dyed is fed into the dyeing space via a roller drive assembly. Under the immersion of the dye liquor, the fabric is dyed. During the dyeing process, the heating assembly maintains the dye liquor in the dyeing space within a suitable dyeing temperature range. The airflow stirring assembly generates a bubble flow, which, together with the dye liquor circulation assembly, circulates the dye liquor in the upper and lower parts of the dyeing space. This improves the uniformity of the dye liquor distribution and allows the dye molecules to penetrate deeper into the fabric fibers under the action of the bubbles, thereby improving the color fastness and uniformity, especially the uniformity of one side of the fabric surface.

[0073] Compared to general dyeing equipment, the dyeing apparatus provided in this embodiment is particularly suitable for miniaturization due to the introduction of airflow stirring and electric heating. This makes it suitable for small-batch, customized processing of high-end fabrics such as silk. At the same time, the introduction of bubble flow and dye liquor circulation designs can improve the dyeing efficiency and uniformity of the fabric, optimize the continuous dyeing quality of roller drive, and facilitate subsequent automation upgrades.

[0074] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
