Description

Water-free fabric dyeing method and fabric dyeing equipment

The present invention relates to the field of fabric dyeing, and in particular to a water-free fabric dyeing method and a fabric dyeing device that utilizes an independent flow-conducting structure to heat and pressurize the dye with steam so that the dye can be closely combined with fabric fibers to form a uniform dyeing performance.

After the fabric is made, in order to make it have the desired color expression for other applications, there is a process in the field of fabric preparation called fabric dyeing. The traditional dyeing process generally has the following steps. The fabric part needs to be boiled first, that is, the fabric is put into a pot and boiled in water to soak the fabric in water to remove the sizing force and make the cloth easy to color. The process of dyeing cloth requires first mixing the required color. The method is to put the dye into a container, add water, stir until the dye dissolves, and then observe and adjust to the desired color. Then, the fabric that has been boiled in water is taken out and dried, and then soaked in a dye vat to allow the fabric to absorb the color of the dye solution. Then it is taken out, wrung out, and placed on a rack to be exposed to the sun. During the dyeing process, the fabric needs to be picked up from time to time to confirm the dyeing status, and then adjust according to the dyeing status. The dyed and dried fabric needs to be rinsed with water to remove floating colors. Generally, it needs to be rinsed at least two to three times, and then the rinsed fabric is put on the rack to dry. Finally, the cloth is rolled and the dyed cloth is smoothed until there are no wrinkles.

From the above dyeing process, we can see that a large amount of water is used in each process, from the initial boiling of cloth to the final rinsing. In practical experience, if you want to dye 1 ton of cloth, you must use more than 30 tons of water. Therefore, in the dyeing process, the use of water has always been a considerable resource consumption. However, the current production methods and equipment still cannot solve the problem of large amounts of water consumption in dyeing.

In view of this, based on many years of rich experience in related industries, the inventor conceived a water-free fabric dyeing method and fabric dyeing equipment to provide a new process solution for dyeing fabrics without water and effectively solve the existing fabric dyeing process. problem.

One of the purposes of the present invention is to provide a water-free fabric dyeing method and fabric dyeing equipment, which is different from the conventional water dyeing process, and uses steam heating and pressurization to tightly bind the dye to the fabric fibers, and achieve uniform dyeing and non-fading performance, thereby achieving the environmental advantages of energy saving and reducing water resource waste.

In order to achieve the above object, the present invention proposes a water-free fabric dyeing method for dyeing a base fabric, which includes the following steps: putting the base fabric in a dyeing cloth working cavity, and making the dyeing cloth working cavity Forming a sealed state; injecting steam from a steam delivery pipeline to maintain the inside of the dyeing working chamber at a predetermined dyeing pressure and dyeing temperature; and injecting nano dye from a dye delivery pipeline into the dyeing working chamber , wherein the weight of the nanodye is 0.1% to 3% of the weight of the base fabric, and the dye delivery pipeline has a continuous first section and a second section, and the second section is located in the steam The first section is located outside the steam transport pipeline and is connected to the dyeing working chamber at one end to form a conduction channel independent of steam; and lasts for a working time to allow the nanodye to The particles are tightly combined with the fibers of the heated base fabric in response to a predetermined dyeing pressure to obtain a dyed fabric.

Based on the same technical concept, the present invention also proposes a water-free fabric dyeing equipment, which includes: a dyeing working chamber, which is used to drape the base fabric and is in a sealed state during the dyeing operation; a steam device, equipped with One side of the dyeing working chamber is used to generate steam; a dye barrel is provided on one side of the dyeing working chamber to contain nano dye, where the weight of the nano dye is the weight of the base fabric 0.1% to 3%; and a transmission component, located on one side of the dyeing working chamber, including: a steam delivery pipeline, one end of which is connected to the steam device, and the other end is connected to the dyeing working chamber; A first pump connected to the steam delivery pipeline for sending the steam from the steam device into the dyeing working chamber to maintain the dyeing working chamber at a predetermined dyeing pressure and dyeing temperature; A dye conveying pipeline has a continuous first section and a second section. The second section is located in the steam conveying pipeline and one end is connected to the dyeing cloth working chamber to form an independent In the steam transmission channel, the first section is located outside the steam delivery pipeline, and one end is connected to the dye barrel; and a second pump is connected to the first section of the dye delivery pipeline It is configured to send the nanodye in the dye barrel to the dyeing working chamber through the dye delivery pipe. After the nanodye is delivered to the dyeing processing chamber, it will be dyed according to the predetermined dyeing process. The pressure of the cloth causes the particles of the nano dye to be tightly bound to the fibers of the heated base cloth.

Preferably, based on the above example, the diameter of the second section of the dye delivery pipeline is 1/4 to 1/3 of the diameter of the steam delivery pipeline, so that the nano dye can enter the dyeing working chamber at an appropriate feeding rate, and at the same time, the space of the overlapping area of the steam delivery pipeline and the second section is not overly compressed to affect the steam delivery state.

Preferably, in view of the different processing conditions required for different colors, the present invention also proposes two weight ratio ranges that can be used. For example, the weight of the nano dye can be 0.1%~2% or 2% of the weight of the base fabric. ~3%.

Preferably, in one embodiment, the preferred dyeing conditions of the fabric dyeing method or apparatus of the present invention are that when the weight of the base fabric is 250Kg to 300Kg, the operation time is at most 1 hour.

Preferably, the predetermined dyeing temperature is 130 degrees C, and the predetermined dyeing pressure is 2Kg, so as to provide a process condition that can accurately dye and form uniform color expression without damaging the base fabric fibers.

To sum up, the water-free fabric dyeing method and fabric dyeing equipment of the present invention propose to use steam pressure and heating to dye the fabric, so that the dye particles can be tightly combined with the base fabric fibers to make Dyed fabrics with uniform color performance and high adhesion, and the dyed fabrics do not have excess dye residues and do not need to be washed. This can avoid the resource consumption of using a large amount of water for processing operations, thereby saving electricity, heat and water resources. environmentally friendly advantages. Regarding further additional technical features that can be added to the fabric dyeing method and equipment to further improve the overall performance, the present invention also provides relevant disclosures, as described in the above paragraphs.

In order to enable people with ordinary knowledge in this field to clearly understand the content of the present invention, please refer to the following description with drawings.

Please refer to Figures 1 to 4, which are the dyeing method step flow chart, dyeing equipment structure schematic diagram and dyeing equipment application schematic diagram (I) and (II) of the preferred embodiment of the present invention. Each figure is only used to illustrate the technical features of the present invention, and does not represent the actual structure, shape, etc., which should be explained in advance. In view of the large amount of water resource consumption in the existing dyeing process, in order to provide a more environmentally friendly and energy-saving fabric dyeing solution, the inventor of the present invention has conceived and proposed a water-free fabric dyeing method and fabric dyeing equipment, which can save a large amount of water required in the dyeing process. At the same time, the dyed fabric also has a more uniform color expression and a strong color adhesion. The following is an explanation of a water-free fabric dyeing method. As shown in FIG. 1 , the fabric dyeing method is used to dye a base fabric A, and includes the following steps: first, the base fabric A is hung in a fabric dyeing working chamber 10, and the fabric dyeing working chamber 10 is formed into a sealed state (step S01). Next, steam is injected from a steam delivery pipeline 131 to keep the inside of the dyeing working chamber 10 at a predetermined dyeing pressure and dyeing temperature; and nano dye 9 is injected into the dyeing working chamber 10 from a dye delivery pipeline 133, wherein the weight of the nano dye 9 is 0.1% to 3% of the weight of the base fabric A, and the dye delivery pipeline 133 has a first section 1331 and a first section 1332 connected in succession, wherein the first section 1332 is located in the steam delivery pipeline 131 and one end is connected to the dyeing working chamber 10 to form a conduction channel independent of steam, and the first section 1331 is located outside the steam delivery pipeline 131 (step S02). The nano dye 9 refers to a dye type whose dyeing particles are nano-sized. The fabric dyeing method is to arrange part of the dye delivery pipeline 133 in the steam delivery pipeline 131, so that the two can share the same injection port opened in the dyeing working chamber 10, so as to strengthen the consistency of the steam and nano dye 9 injection, and make the nano dye 9 evenly distributed in the dyeing working chamber 10 in response to the steam, and reduce the influence of too many holes in the dyeing working chamber 10 on the overall sealing degree. At the same time, it can also prevent the dye from contaminating the steam delivery pipeline 131, and it is more convenient to clean and replace the dye color. In addition, through the special steps of the fabric dyeing method, the weight of the nano dye 9 only needs to be 0.1% to 3% of the weight of the base fabric A to dye the entire base fabric A into a uniform and color-fast fabric.

Then, the operation is continued for a certain period of time, so that the particles of the nano dye 9 are tightly bonded to the fibers of the heated base fabric A in response to the predetermined dyeing pressure, and a dyed fabric B is obtained (step S03). The nano dye A and the steam can be injected one after another or simultaneously according to the actual process. After the steam is injected into the closed dyeing working chamber 10, the predetermined dyeing pressure and dyeing temperature can be formed inside the dyeing working chamber 10 by the steam, so that the base fabric A is heated to cause the fibers to stretch and be more easily bonded with the nano dye 9. When the temperature drops and the base fabric A is cooled, the fibers of the base fabric A can tightly wrap and hold the nano dye 9 particles, thereby enhancing the color fixation of the dyed fabric B. In order to make the dye adhere smoothly and firmly to the fibers of the base fabric A, the fabric dyeing method is particularly limited to use nano dye 9. In other words, when the dye particles are reduced to the nanometer scale, they are more surely bonded to the fibers of the base fabric A by heating and pressurizing.

According to this, through the fabric dyeing method, it is not necessary to use a large amount of water for the dyeing process, and the dye can be tightly bonded to the fibers of the base fabric A by relying on the effect of steam. The principle is that when the fibers of the base fabric A are unfolded in response to the heating effect, forming a state like the fibers are unfolded, at this time, after the nano-scale particles of the nano-dye 9 enter the dyeing working chamber 10, they are also affected by the predetermined dyeing pressure and are evenly dispersed in the dyeing working chamber 10 and attached to the fibers of the base fabric A. After the operation time, the fibers of the base fabric A are cooled and the particles of the nano-dye 9 are coated inside to form a strong attachment state that is not easily removed by external force, which can greatly reduce the probability of fabric fading. In addition, the dyed fabric B obtained by the fabric dyeing method does not need to go through a washing process, so the clean water used for washing can be completely omitted, which can effectively save energy and water.

In practical application, it is preferred that the diameter of the second section 1332 of the dye delivery pipeline 133 is 1/4 to 1/3 of the diameter of the steam delivery pipeline 131, so that the nano dye 9 can enter the dyeing working chamber 10 at a better injection rate, and at the same time, the second section 1332 will not be too large to compress the space between the steam delivery pipeline 131 and the overlapping space, so that the steam is blocked by the second section 1332 and is not conducive to entering the dyeing working chamber 10. In this embodiment, the diameter of the second section 1332 is 1/4 of the diameter of the steam delivery pipeline 131.

Through the above-mentioned fabric dyeing method, the amount of nano dye 9 used is quite small compared to the amount of dye solution in the traditional fabric dyeing process. According to the feedback from actual use experience, the amount of nano dye 9 used is related to the type and depth of color that the dyed fabric B is intended to present. Based on different types of colors or depths, the fabric dyeing method proposes better implementation range conditions, one of which is that the weight of nano dye 9 is 0.1%~2% of the weight of the base fabric, and the other is that the weight of nano dye 9 is 2%~3% of the weight of the base fabric. For example, if the color of the dyed fabric B is desired to have a darker expression or the color type is a dark color series, the weight of the nano dye 9 can be 2% to 3% of the weight of the base fabric A. This can increase the density of the dye particles in the internal space of the dyeing working chamber 10 during the dyeing process, so that more dye particles can be bound to the unit fiber area, and a darker color expression is displayed. If the dyed fabric B is desired to be a dark color series but has a lighter expression, or to be dyed to form a light color series fabric, the weight of the nano dye 9 can be 0.1% to 2% of the weight of the base fabric A. Furthermore, when preparing the dyed fabric B to form a light color series, the weight of the nano dye 9 can also be 0.1% to 0.3 of the weight of the base fabric A. Within the above-mentioned weight ranges, adjustments can be made according to the target color to obtain the dyed fabric B with uniform dyeing and extremely high color fixation.

In addition to being able to prepare the high-quality dyed fabric B, the fabric dyeing method can also effectively reduce the required operating time during the dyeing process, thereby saving processing costs such as time and electricity. Preferably, when the weight of the base fabric A is 250Kg to 300Kg, the operating time is at most 1 hour to make the base fabric A into the evenly dyed dyed fabric B, thereby having the advantage of high-efficiency preparation.

Furthermore, in a preferred embodiment, the predetermined dyeing temperature can be 130 degrees C, and the predetermined dyeing pressure can be 2Kg. Under these processing conditions, excessive pressure and high temperature can be avoided to cause the base fabric A to At the same time, it can also prevent the nano dye particles from being tightly combined with the fibers of the base fabric A due to excessively low temperature and pressure, so that the high-quality dyed fabric B can be perfectly made.

The following is a description of a better application state. Please refer to Figures 3 and 4. When dyeing is to be performed, the base fabric A is hung on a movable support frame. The base fabric A can be 250Kg. , and then put it into the dyeing working cavity 10, and then close the dyeing working cavity 10 to form a sealed state. Then, the steam and the nano dye 9 are injected into the dyeing working chamber 10, so that the weight of the nano dye 9 is 2% of the weight of the base cloth A, that is, about 5 Kg. Through the injected steam, the internal space of the dyeing working chamber 10 can be maintained at the predetermined dyeing pressure and dyeing temperature. Here, the dyeing pressure is 2Kg, the dyeing temperature is 130 degrees C, and the overall operating time is 1 hours as an example. The nano dye 9 is injected into the dyeing cloth working chamber 10 through the dye delivery pipe 133, and in response to the pressure of the dyeing cloth, the dye particles are tightly combined with the fibers of the base cloth A that are expanded after being heated. When the dyeing working chamber 10 meets the predetermined dyeing pressure and dyeing temperature conditions and all the nanodyes 9 are injected, the steam input can be stopped and the base fabric A can be allowed to stand, allowing the nanodyes 9 to The particles are tightly combined with the fibers of the heated base fabric A in response to the predetermined dyeing pressure, and then the dyed fabric B is obtained. What is particularly worth mentioning is that after the dyeing working chamber 10 is opened or the steam in the dyeing working chamber 10 is eliminated, the base fabric A cools in response to the temperature drop, causing its fibers to undergo convergence changes. Nano dye The particles of 9 can be tightly fixed in the fibers of the base fabric A, thereby further solidifying the dye particles on the dyed fabric B.

Please refer to Figures 1 to 4 again. Based on the same technical concept, the present invention also proposes a water-free fabric dyeing device 1 for dyeing a base fabric A, which includes a dyeing working chamber 10, a steam device 11, a dye barrel 12 and a transfer component 13.

The dyeing working chamber 10 is used to hang the base fabric A and is in a closed state during the dyeing operation. Preferably, the dyeing working chamber 10 can be provided with an automatic or manual door panel to control the internal space state, and in order to facilitate the confirmation of the internal pressure and temperature of the dyeing working chamber 10, the dyeing working chamber 10 can also be provided with a pressure detector and a temperature detector. The steam device 11 is provided at one side of the dyeing working chamber to generate steam, and the dye barrel 12 is provided at one side of the dyeing working chamber 10 to contain the nano dye 9, wherein the weight of the nano dye 9 is 0.1% to 3% of the weight of the base fabric A.

The transmission component 13 is located on one side of the dyeing working chamber 10 and includes a steam delivery pipeline 131 , a first pump 132 , a dye delivery pipeline 133 and a second pump 134 . One end of the steam delivery pipeline 131 is connected to the steam device 11 and the other end is connected to the dyeing working chamber 10 to form a channel that can transmit the steam generated by the steam device 11 to the dyeing working chamber 10 . The first pump 132 is connected to the steam delivery pipeline 131 for sending the steam from the steam device 11 into the dyeing working chamber 10 to maintain the dyeing working chamber 10 at a predetermined dyeing temperature. Cloth pressure and dyeing temperature. The dye delivery pipeline 131 has a continuous first section 1311 and a second section 1312. The second section 1312 is located in the steam delivery pipeline 131 and has one end connected with the dyeing working chamber 10 , to form a conductive channel independent of steam, the first section 1311 is located outside the steam transmission pipeline 131 , and one end is connected to the dye barrel 12 . The second pump 134 is connected to the first section 1311 of the dye transport pipeline 131 and is used to transport the nanodye 9 in the dye barrel 12 to the dye via the dye transport pipeline 131 . In the cloth working chamber 10, after the nano dye 9 is transferred to the dyeing processing chamber 10, the particles of the nano dye 9 are tightly combined with the heated base cloth A in response to the predetermined dyeing pressure. on fiber. The first pump 132, the second pump 134 and the steam device 10 can automatically control their operating states through control equipment. Of course, the delivery rate and intensity of the steam or nanodye 9 can also be manually adjusted at any time. etc.

Accordingly, the fabric dyeing device 1 can completely avoid the use of water to prepare dye solution for fabric soaking during the dyeing process, as well as the large amount of water used for washing floating color after dyeing. In addition, in the technical solution of using steam to form a predetermined dyeing pressure and dyeing temperature, the amount of nano dye 9 and the overall dyeing time can be greatly reduced, thereby achieving the advantages of energy saving and environmental protection. At the same time, the fabric dyed by the fabric dyeing device 1 is formed by the predetermined dyeing temperature to form the base fabric A in a fiber-expanded state, and then the particles of the nano dye 9 are tightly combined with the fibers of the base fabric in response to the predetermined dyeing pressure. After the particles of the nano dye 9 are tightly combined with the fibers of the base fabric A, the temperature in the dyeing working chamber 10 is lowered to allow the fibers of the base fabric A to re-contract in response to cooling, so that the particles of the nano dye 9 are firmly combined with the fibers of the base fabric A, so as to obtain the dyed fabric B.

It is particularly mentioned that the steam delivery pipeline 131 and the dye delivery pipeline 133 of the cloth dyeing equipment 1 form independent but partially overlapping flow channels, which can prevent the nano dye 9 from contaminating the steam. The conveying pipeline 131 also facilitates cleaning of the dye barrel 12 and the dye conveying pipeline 133 when changing the color of the dye. As for the aforementioned independent flow channel, the cloth dyeing equipment 1 further disposes the second section 1332 of the dye conveying pipe 133 inside the steam conveying pipe 131, so that it can be connected with the steam conveying pipe 131. The same injection port of the dyeing working chamber 10 is shared, so that when the nanodye 9 is injected into the dyeing working chamber 10, it can be evenly distributed in the dyeing work in response to the steam injected from the steam delivery pipeline 131. The power of the internal space of the cavity 10 can also reduce the number of openings in the dyeing working cavity 10 to better maintain the sealing property of the dyeing working cavity 10 .

Similar to the cloth dyeing method, the diameter of the second section 1332 of the dye delivery pipeline 133 can also be 1/4 to 1/3 of the diameter of the steam delivery pipeline 131, so as to have better transmission performance. It can also prevent the second section 1332 from affecting the space where the steam transport pipeline 131 overlaps with the second section 1332, causing the steam injection to be difficult or too slow. Furthermore, regarding the weight ratio of the nano dye 9, for example, if you want to dye a dark color but a lighter or lighter color, the ratio of the weight of the nano dye 9 to the weight of the base fabric A can be 0.1% to 2%. If you want to dye dark colors and express deeper colors, the ratio of the weight of nanodye 9 to the weight of base fabric A can be 2% to 3%. Furthermore, if you want to dye light colors, the ratio of the weight of the nano dye 9 to the weight of the base fabric A can be 0.1% to 0.3%. The advantages and effects of the above weight ratio have been described in the corresponding paragraphs above. Please refer to the above content again and will not be repeated here.

In addition, in actual process application, a preferred embodiment discloses that when the weight of the base fabric A is 250Kg to 300Kg, the operation time is at most 1 hour, that is, through the various technical features of the fabric dyeing equipment 1, when the base fabric A in the above weight range is dyed, the operation time is set to less than 1 hour to make the base fabric A dyed to form a uniform fabric with high color intensity, thereby having the advantages of fastness and energy saving. For other related detailed technical features and corresponding effect descriptions, please refer to the above paragraphs, and will not be repeated here.

In addition, the present invention also proposes a better example of process conditions. When the weight of the base fabric A is within the above range and the operating time is within the above conditions, the predetermined dyeing temperature can be 130 degrees C and the predetermined dyeing pressure can be 2Kg. In this way, the required dyed fabric can be dyed and formed. For other related detailed technical features and corresponding function descriptions, please refer to the previous paragraphs and will not be repeated here.

The application of the fabric dyeing device 1 can be combined with reference to FIGS. 3 and 4. After the base fabric A is draped in the fabric dyeing working chamber 10, the fabric dyeing working chamber 10 is sealed to start the dyeing process. The working door of the fabric dyeing working chamber 10 can be opened and closed manually or automatically. Then, the first pump 132 and the second pump 134 are driven to inject steam and nano dye 9 from the steam delivery pipeline 131 and the dye delivery pipeline 133 into the dyeing working chamber 10 respectively, wherein the steam and the nano dye 9 are in independent flow conduction states, but share the same injection port of the dyeing working chamber 10, so that the nano dye 9 can be more easily evenly distributed in the dyeing working chamber 10 in response to the steam when injected into the dyeing working chamber 10. When the predetermined dyeing temperature and dyeing pressure are reached in the inner space of the dyeing working chamber 10, the first pump 132 can be temporarily stopped or the driving state of the first pump 132 can be adjusted to ensure that the dyeing working chamber 10 meets the aforementioned dyeing temperature and dyeing pressure state. The same as the description of Figures 3 and 4 in the section of the fabric dyeing method, the processing conditions here are also based on the weight of the base fabric A of 250Kg, the weight of the nano dye is 5Kg, the predetermined dyeing pressure is 2Kg, the dyeing temperature is 130 degrees C, and the working time is 1 hour. Then wait for the particles of the nano dye 9 to be tightly bonded to the fibers of the base fabric A in response to the predetermined dyeing pressure to form the dyed fabric B. After the dyed fabric B is moved out of the dyeing working chamber 10 or the dyeing working chamber 10 is made into an unsealed state so that the steam flows to the outside, the fibers of the base fabric A will shrink again due to the drop in temperature, and the bonding strength between the particles of the nano dye 9 and the fibers of the base fabric A will be further enhanced, thereby greatly enhancing the color fastness of the dyed fabric B.

In summary, the water-free fabric dyeing method and equipment of the present invention are based on the dyeing pressure and dyeing temperature formed by steam in the dyeing working chamber, and combined with the action of nano dyes, it can achieve short processing time and low dyeing. Under the conditions of the dosage of the agent, the dyed fabric with high color adhesion strength can be successfully produced. More importantly, the fabric dyeing method and the fabric dyeing equipment do not need to use a large amount of water as dye preparation or cleaning of the dyed fabric. This system can greatly reduce the water consumption in the dyeing process and achieve the advantage of energy saving. At the same time, the preparation process is relatively fast and convenient, and simultaneously reduces the electricity, heat and other energy required for the process. In addition, the steam delivery pipeline and the dye delivery pipeline of the present invention are partially overlapping independent flow channels, thereby making it easier to synchronize the nanodye when injected into the dyeing working chamber. It is driven by the steam and evenly distributed in the space. At the same time, the steam delivery pipeline and the dye delivery pipeline share the same injection port of the dyeing cloth working cavity, thereby improving the structural integrity of the dyeing cloth working cavity. sex. It should be noted that in the field of fabric dyeing technology, there is no technical solution as described in the present invention. In other fields of fabric processing, even if there are similar structures, their applications are different from the dyeing requirements of the present invention. There is no incentive to configure the vapor delivery pipeline and the dye delivery pipeline as independent flow channels that partially overlap each other as in the present invention. What's more, the steam delivery pipeline and the dye delivery pipeline of the present invention are not only independent of each other, but the dye delivery pipeline must also be partially located within the steam delivery pipeline and shared with the steam delivery pipeline. The same injection port allows the nano-dye to be evenly distributed in the internal space of the dyeing working chamber in response to the steam, which is more conducive to the combination of the particles of the nano-dye with the base fabric fibers and forms a uniform color expression. Dyed fabric. Specifically, the intuitive design direction generally does not allow the dye and steam to be injected into the dyeing working chamber through separate pipelines. However, the inventor found through experiments that such a pipeline design will cause the dye to be easily retained. In the steam pipeline, it causes great inconvenience in cleaning. If the color of the dye needs to be changed, it is not easy to clean up the retained dye. It may be possible to completely separate the dye pipeline and the steam pipeline to avoid the above situation, but in this case, you need to choose to open different connection holes in the working chamber so that the dye and steam can enter the work through completely different injection ports. However, this structure will affect the structural integrity of the working cavity and make it difficult for the dye to be evenly distributed in the space. Therefore, after constant experimentation and thinking, the inventor proposed a technical solution that is brand new and different from the previous structure and has unexpected effects. In addition, the present invention also specifically limits the use of dyes to nano dyes, and its weight ratio to the base fabric is also specifically disclosed. Under this range of conditions, it can be dyed to form excellent dyed fabrics, achieving Reduce the dosage of dye. Furthermore, the present invention also has many related disclosures regarding the diameter ratio of the second section of the dye delivery pipeline to the steam delivery pipeline, or preparation and processing conditions, etc., to further improve the overall dyeing performance.
