Description

Water-free fabric dyeing method and fabric dyeing equipment

The present invention is related to the field of fabric dyeing, especially a water-free fabric dyeing method and fabric dyeing equipment that enables dyes to be closely combined with fabric fibers to form uniform dyeing performance through steam heating and pressurization through an independent flow conduction structure.

After the cloth is made, in order to form the required color expression for other applications, there is a method in the field of cloth preparation called cloth dyeing. The traditional cloth dyeing process generally has the following steps. The cloth part needs to be boiled first, that is, the cloth is put into a pot and boiled with clean water, so that the cloth is soaked in water to remove the starch and make the cloth easy to color. In the process of dyeing cloth, the required color needs to be prepared first. The method is to put the dye into a container, add water, stir until the dye is dissolved, and then observe and adjust to the desired color. Then take out the cloth that has been boiled in clear water and dry it, then soak it in the dye vat to make the cloth absorb the color of the dye solution, then take it out, wring it out and put it on the rack for exposure. In the dyeing process, the fabric needs to be picked up from time to time to confirm the dyeing status, and then adjusted according to the dyeing status. After dyeing, the sun-dried fabric needs to be rinsed with clean water to remove the floating color. Generally, it needs to be rinsed at least two to three times, and then the rinsed fabric is put on the shelf to dry. Finally, the cloth is rolled, and the dyed cloth is flattened until there are no wrinkles.

From the above-mentioned dyeing process, it can be seen that a large amount of water is used in each process from the initial boiling of the cloth to the final rinsing. According to practical experience, if 1 ton of cloth is to be dyed, more than 30 tons of water must be used. Therefore, in the cloth 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 consuming a large amount of water for dyeing cloth.

In view of this, based on 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 fabric dyeing without water, effectively solving the problems of the existing fabric dyeing process.

One object of the present invention is to provide a water-free fabric dyeing method and fabric dyeing equipment, which is different from the previous water dyeing process, and through steam heating and pressure, the dye can be tightly combined on the fabric fibers, and the performance of uniform dyeing and not easy to decolorize can be achieved, and the environmental protection advantages of energy saving and waste of water resources can be achieved based on this.

In order to achieve the above-mentioned purpose, the present invention proposes a method for dyeing fabric without water, which is used for dyeing a base fabric, including the following steps: hanging the base fabric in a dyeing fabric working chamber, and making the dyeing fabric working chamber form an airtight state; injecting steam from a steam delivery pipeline to keep the inside of the dyeing fabric working chamber at a predetermined dyeing pressure and dyeing temperature; 3%, and the dye delivery pipeline has a continuous first section and a second section, the second section is located in the steam delivery pipeline and one end is connected to the dyeing cloth working cavity to form a conduction channel independent of the steam, the first section is located outside the steam delivery pipeline; and lasts for a working time, so that the particles of the nano-dye are closely combined with the fibers of the heated base fabric according to the predetermined dyeing pressure, and a dyed fabric is obtained.

Preferably, based on the above example, the diameter of the second section of the dye delivery pipeline is 1/4~1/3 of the diameter of the steam delivery pipeline, so that the nano-dye can enter the dyeing working chamber at an appropriate feed rate, and at the same time, the space in the overlapping area between the steam delivery pipeline and the second section will not be too 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 available weight ratio ranges, for example, the weight of nano dyes can be 0.1%~2% or 2%~3% of the weight of the base fabric.

Preferably, the fabric dyeing method disclosed in an embodiment of the present invention or the preferred dyeing conditions of the equipment dyeing fabric is that when the weight of the base fabric is 250Kg~300Kg, the working time is at most 1 hour.

Preferably, the predetermined dyeing temperature is 130°C, and the predetermined dyeing pressure is 2Kg/cm ² , so as to provide a process condition that can be accurately dyed to form a uniform color expression, and at the same time will not damage the fibers of the base fabric.

In order to enable those skilled in the art to clearly understand the content of the present invention, the following descriptions are provided together with the drawings for your reference.

Please refer to Figures 1 to 4, which are the flow chart of the dyeing method steps, the structural schematic diagram of the dyeing equipment and the application schematic diagrams (1) and (2) of the dyeing equipment in a preferred embodiment of the present invention. Wherein each figure is shown only for the technical characterictic of the present invention for schematic illustration, does not represent the actual structure exterior scale gauge etc., and narrates first. In view of the lack of a large amount of water consumption in the existing cloth dyeing process, in order to provide a more environmentally friendly and energy-saving cloth dyeing solution, the inventor conceived and proposed a cloth dyeing method and cloth dyeing equipment without water, which can save a lot of water required in the dyeing process, and at the same time, the dyed cloth also has more Uniform color performance and strong color adhesion. The following is a description of the fabric dyeing method without water. As shown in Figure 1, the fabric dyeing method is used to dye a base fabric A. It includes the following steps: first hang the base fabric A in a cloth dyeing working chamber 10, and make the cloth dyeing working chamber 10 form an airtight state (step S01). Then, inject steam 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 inject nano-dye 9 from a dye delivery pipeline 133 towards the dyeing working chamber 10, wherein the weight of the nano-dye 9 is 0.1% to 3% of the weight of the base cloth A, and the dye delivery pipeline 133 has a first section 1331 and a second section 1332 connected to it, the first section 1332 It is located in the steam delivery pipeline 131 and one end is connected to the cloth dyeing working chamber 10 to form a conduction channel independent of the steam, and the first section 1331 is located outside the steam delivery pipeline 131 (step S02 ). Wherein, nanometer dye 9 refers to the kind of dye whose dyed particles are of nanometer size. The cloth dyeing method uses the structure in which part of the dye delivery pipeline 133 is arranged in the steam delivery pipeline 131, so that the two can share the same injection port provided by the dyeing working chamber 10, so as to strengthen the consistency of injecting the steam and the nano-dye 9, and make the nano-dye 9 evenly distributed in the dyeing working chamber 10 in response to the steam, and reduce the overall airtightness caused by setting too many holes in the dyeing working chamber 10. This prevents the dye from polluting the steam delivery pipeline 131, and it is more convenient to clean and replace the color of the dye. In addition, through the special steps of the fabric dyeing method, the weight of the nano-dye 9 only needs to be 0.1%~3% of the weight of the base fabric A to dye the base fabric A as a whole to form a uniform and firm-colored fabric.

Then continue for a working time, so that the particles of the nano-dye 9 are closely combined with the fibers of the heated base cloth A according to the predetermined dyeing pressure, and a dyed cloth B is obtained (step S03). Wherein, the injection of the nanometer dye 9 and the steam can be injected sequentially or at the same time depending on the actual process. When the steam is injected into the dyeing working chamber 10 in a sealed state, the predetermined dyeing pressure and dyeing temperature can be formed inside the dyeing working chamber 10 by steam, and the base fabric A is heated to promote the stretching of the fibers and make it easier to integrate with the nanometer dyeing agent 9. The dye 9 is combined, and when the temperature drops to cool the base fabric A, the fibers of the base fabric A can tightly cover the nano-dye 9 particles, and the color fixation of the dyed fabric B can be enhanced. Among them, in order to allow the dye to adhere smoothly and firmly to the base fabric A fiber, the fabric dyeing method specifically restricts the use of nano-dye 9. In other words, when the dye particles are reduced to the nanoscale level, they can be more reliably bonded to the base fabric A fiber by heating and pressing.

Accordingly, through the cloth dyeing method, it is not necessary to use a large amount of water to carry out the cloth dyeing process, relying on the effect of steam to make the dyes tightly bonded to the fibers of the base cloth A. The principle is that when the fibers of the base fabric A are expanded in response to heating, a fiber-expanded state is formed. At this time, after the nano-sized 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 working time, the fibers of the base fabric A can be cooled. It can greatly reduce the chance of fabric fading. In addition, the dyed fabric B obtained through the fabric dyeing method does not need to go through the washing process, so the clean water used for washing can be completely omitted, which can effectively save energy and water.

In practical applications, it is preferable to make the diameter of the second section 1332 of the dye delivery pipeline 133 1/4~1/3 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 space where the steam delivery pipeline 131 overlaps with the second section 1332 will not be compressed due to the excessive diameter of the second section 1332, causing the steam to be blocked by the second section 1332. It is beneficial to enter the working chamber 10 for dyeing cloth. In this embodiment, it is taken that the pipe diameter of the second section 1332 is 1/4 of the pipe diameter of the steam delivery pipeline 131 as an example.

Through the above-mentioned fabric dyeing method, the amount of nano-dye 9 is quite small compared to the amount of dye solution in the traditional dyeing process, and based on the feedback from actual use, the amount of nano-dye 9 is the same as The type of color that the dyed fabric B intends to present is related to the shade. Based on different color types or shades, the fabric dyeing method proposes a better implementation range condition. One is that the weight of nano dye 9 is 0.1%~2% of the weight of the base cloth, and the other is that the weight of nano dye 9 is 2%~3% of the weight of the base cloth. For example, if the color of the dyed fabric B is expected to be darker or the color is dark, the weight of the nano-dye 9 can be 2% to 3% of the weight of the base fabric A, so that the density of the dye particles in the inner space of the dyeing working chamber 10 during the dyeing process can be increased, so that the unit fiber area can have more dye particles bonded to it, thus showing a darker color performance. If it is desired that the dyed fabric B is of a dark color but has a lighter appearance, or dyed to form a light-colored 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 of a light color system, the weight of the nano-dye 9 may be 0.1%-0.3 of the weight of the base fabric A. And within each weight range mentioned above, it can be adjusted according to the target color, and the dyed fabric B with uniform dyeing and extremely high color fixation can be obtained.

The fabric dyeing method can not only prepare the high-quality dyed fabric B, but also effectively reduce the required working time in the dyeing process, thereby saving processing costs such as time and electric energy. Preferably, when the weight of the base fabric A is 250Kg~300Kg, the working time is at most 1 hour to make the base fabric A into the dyed fabric B that is evenly dyed, and has the advantage of high-efficiency production.

Further, in a preferred embodiment, the predetermined dyeing temperature is 130°C, and the predetermined dyeing pressure is 2Kg/cm ² . Under these processing conditions, damage to the base fabric A caused by excessive pressure and high temperature can be avoided. At the same time, it can also prevent the particles of the nano-dye from being unable to tightly bond to the fibers of the base fabric A due to low temperature and pressure. In this way, the dyed fabric B with high quality can be perfectly produced.

The following is a description of a preferred application state. Please refer to the 3rd and 4th figures. When the dyeing process is to be performed, the base cloth A is hung on a movable support frame, wherein the base cloth A can be 250Kg, and then it is placed in the dyeing cloth working chamber 10, and then the dyeing cloth working chamber 10 is closed to form an airtight state. Then inject the steam and the nano-dye 9 into the working cavity 10 of the dyeing cloth, wherein the weight of the nano-dye 9 can be 2% of the weight of the base cloth A, that is, about 5Kg. The inner space of the dyeing working chamber 10 can be kept at the predetermined dyeing pressure and dyeing temperature through the injected steam system. Here, the dyeing pressure is 2Kg/cm ² , the dyeing temperature is 130°C, and the overall working time is 1 hour as an example. The nano-dye 9 is injected into the dyeing working chamber 10 through the dye delivery pipeline 133, and the dye particles are closely combined with the fibers of the base fabric A that are expanded after being heated in response to the pressure of the dyed cloth. When the dyeing cloth working chamber 10 meets the preset dyeing pressure and dyeing temperature conditions and the injection of the nano-dye 9 is completed, the input of steam can be stopped and the base cloth A is allowed to stand still, so that the particles of the nano-dye 9 are closely combined with the fibers of the heated base cloth A according to the predetermined dyeing pressure, and then the dyed cloth B is obtained. What is particularly worth mentioning is that after opening the dyeing working cavity 10 or removing the steam in the dyeing working cavity 10, the base fabric A cools down due to the temperature drop, causing the fibers to be bundled, and the particles of the nano-dye 9 can be tightly fixed in the fibers of the base fabric A, 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 cloth dyeing device 1 for dyeing a base cloth A, including a cloth dyeing working chamber 10, a steam device 11, a dye bucket 12 and a transmission unit 13.

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

The conveying unit 13 is located on one side of the cloth 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 cloth dyeing working chamber 10 to form a passage for delivering the steam generated by the steam device 11 to the cloth dyeing working chamber 10 . The first pump 132 is communicated with the steam delivery pipeline 131 for sending the steam from the steam device 11 into the fabric dyeing working cavity 10 to keep the fabric dyeing working cavity 10 at a predetermined dyeing pressure and temperature. The dye delivery pipeline 133 has a continuous first section 1331 and a second section 1332. The second section 1332 is located in the steam delivery pipeline 131 and one end is connected to the cloth dyeing working chamber 10 to form a conduction channel independent of the steam. The first section 1331 is located outside the steam transmission pipeline 131 and one end is connected to the dye bucket 12. The second pump 134 is connected to the first section 1331 of the dye delivery pipeline 131, and is used to send the nano-dye 9 in the dye barrel 12 to the dyeing working chamber 10 through the dye delivery pipeline 133. After the nano-dye 9 is sent to the dyeing processing chamber 10, the particles of the nano-dye 9 are tightly bound to the fibers of the heated base fabric A according to the predetermined dyeing pressure. Wherein the first pump 132, the second pump 134 and the steam device 11 can automatically control their actuation states through the control equipment. Of course, the delivery rate and intensity of the steam or the nano-dye 9 can also be adjusted manually at any time.

Accordingly, the fabric dyeing equipment 1 can completely avoid the use of water to prepare the dye solution for fabric soaking in the fabric dyeing process, and the large amount of water used in the floating color washing after dyeing, and 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 cloth dyed by the cloth dyeing equipment 1 is because the base cloth A is formed into a state like fiber expansion through the predetermined dyeing temperature, and then the particles of the nano-dye 9 can be tightly combined with the fibers of the base cloth according to the predetermined dyeing pressure. After the particles of the nano-dye 9 are tightly combined with the fibers of the base cloth A, the dyeing process The temperature inside the cavity 10 can make the fibers of the base cloth A shrink again in response to cooling, so that the particles of the nano-dye 9 are firmly combined on the fibers of the base cloth A to obtain the dyed cloth B.

In particular, the steam conveying pipeline 131 and the dye conveying pipeline 133 of the cloth dyeing equipment 1 form independent but partially overlapping conduction passages, which can prevent the nano-dye 9 from contaminating the steam conveying pipeline 131, and also facilitate cleaning of the dye tank 12 and the dye conveying pipeline 133 when changing the color of the dye. For the aforementioned independent conduction channel, the cloth dyeing equipment 1 makes the second section 1332 of the dye delivery pipeline 133 be arranged inside the steam delivery pipeline 131, so that it can share the injection port of the same dyeing working cavity 10 with the steam delivery pipeline 131, so that when the nano dye 9 is injected into the dyeing working cavity 10, it can have the power evenly distributed in the inner space of the dyeing working cavity 10 due to the steam injected from the steam delivery pipeline 131. At the same time, the number of openings in the cloth dyeing working chamber 10 can be reduced to better maintain the airtightness of the cloth dyeing working chamber 10 .

Same as the fabric dyeing method, the diameter of the second section 1332 of the dye delivery pipeline 133 can also be 1/4~1/3 of the diameter of the steam delivery pipeline 131, so as to have better delivery performance in transmission, and also prevent the second section 1332 from affecting the space where the steam delivery pipeline 131 overlaps with it, resulting in difficult or slow steam injection. Further, regarding the weight ratio of the nano-dye 9, for example, if you want to dye a dark color but express a lighter or light-colored color, you can make the ratio of the weight of the nano-dye 9 to the weight of the base cloth A to be 0.1% to 2%, and if you want to dye a dark color and express a darker color, you can make the ratio of the weight of the nano-dye 9 to the weight of the base cloth A to be 2% to 3%. Furthermore, if it is desired to dye a light-colored color, the ratio of the weight of the nano-dye 9 to the weight of the base fabric A may be 0.1%-0.3%. The advantages and effects of the above weight ratios have been mentioned in the previous corresponding paragraphs, please refer to the foregoing content, and will not repeat them here.

In addition, in the actual process application, a preferred embodiment discloses that when the weight of the base fabric A is 250Kg~300Kg, the working time is at most 1 hour, that is, through the fabric dyeing equipment 1 According to the various technical features, when dyeing the base fabric A in the above weight range, the working time is set to be less than 1 hour, so that the base fabric A can be dyed to form a uniform fabric with high coloring strength, which has the advantages of fast and energy saving. For the rest of the relevant detailed technical features and corresponding function descriptions, please refer to the previous paragraphs, and will not repeat them here.

In addition, the present invention also proposes an example of better process conditions. When the weight of the base fabric A is in the above-mentioned range and the working time is in the above-mentioned conditions, the predetermined dyeing temperature can be 130°C, and the predetermined dyeing pressure can be 2Kg/cm ² , so that the required dyed cloth can be dyed. For the rest of the relevant detailed technical features and corresponding function descriptions, please refer to the previous paragraphs, and will not repeat them here.

The application of the fabric dyeing equipment 1 can be combined with reference to Figures 3 and 4, and the base fabric A is hung behind the dyeing working cavity 10, even if the dyeing working cavity 10 is sealed to start the dyeing process. Wherein the working door of the cloth dyeing working chamber 10 can be opened and closed manually or automatically. Then drive the first pump 132 and the second pump 134 to inject steam and nano-dye 9 from the steam delivery line 131 and the dye delivery line 133 respectively into the dyeing working cavity 10, wherein the steam and the nano-dye 9 are independent of each other, but share the same injection port of the dyeing working cavity 10, so that when the nano-dye 9 is injected into the dyeing working cavity 10, it is easier to spread evenly in the dyeing cloth due to steam Inside the working chamber 10. After the predetermined dyeing temperature and dyeing pressure 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 dynamically adjust to ensure that the dyeing temperature and dyeing pressure in the dyeing working chamber 10 meet the aforementioned dyeing temperature and dyeing pressure. And the same as the description of Figure 3 and Figure 4 in the paragraph 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/cm ² , the dyeing temperature is 130 degrees C, and the working time is 1 hour as an example. Then wait until the particles of the nano-dye 9 are closely combined with the fibers of the base fabric A according to the predetermined dyeing pressure to form the dyed fabric B. After the dyed cloth B is moved out of the dyeing cloth working chamber 10 or the dyeing cloth working chamber 10 is formed into an unsealed state to allow steam to flow to the outside, the fibers of the base cloth A will shrink again as the temperature drops to further increase the bonding strength between the particles of the nano-dye 9 and the fibers of the base cloth A, and the color fastness of the dyed cloth B can be greatly enhanced.

To sum up, the water-free fabric dyeing method and equipment of the present invention, through the dyeing pressure and dyeing temperature formed in the working chamber of the dyeing fabric by steam, combined with the action of nano-dye, can successfully produce the dyed fabric with high color adhesion strength under the conditions of short processing time and low dye dosage. More importantly, the fabric dyeing method and the fabric dyeing equipment do not need to use a large amount of water for dye preparation or cleaning of dyed fabric in application, which can greatly reduce water consumption in the dyeing process. , to achieve the advantages of energy saving, and at the same time, the preparation process is relatively fast and convenient, and simultaneously reduces the energy required for the process, such as electric energy and heat energy. In addition, the steam delivery pipeline and the dye delivery pipeline of the present invention are partially overlapped independent conduction channels, so that the nano-dye can be more easily driven by the steam and evenly distributed in the space when it is injected into the dyeing working cavity, and also allows the steam delivery pipeline and the dye delivery pipeline to share the same injection port of the dyeing working cavity, thereby improving the structural integrity of the dyeing working cavity. It should be noted that in the field of cloth dyeing technology, there is no technical solution as described in the present invention, and in other cloth processing fields, even if there is a similar structure, because its application is different from the dyeing requirements of the present invention, there is no motivation to set it as an independent conduction channel that partially overlaps with 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 also the dye delivery pipeline must be partially located in the steam delivery pipeline, and share the same injection port with the steam delivery pipeline, so that the nano-dye can be evenly distributed in the inner space of the dyeing working chamber in response to the steam, so as to facilitate the combination of the nano-dye particles and the base fabric fibers, and form the dyed fabric with uniform color performance. Specifically, the intuitive design direction generally does not make the dye and steam injected into the dyeing working chamber with separate pipelines. However, the inventors have found through experiments that such a pipeline design will cause the dye to stay in the steam pipeline very easily, and it will cause great inconvenience in cleaning. If the color of the dye needs to be changed, it is not easy to clean the retained dye. It may be possible to completely separate the dye pipeline from the steam pipeline to avoid the above situation. However, it is necessary to choose different connection holes on the working chamber so that the dye and steam enter the working chamber through completely different injection ports. However, this structure will affect the structural integrity of the working chamber, and it is not easy to distribute the dye evenly in the space. Therefore, after continuous experimentation and thinking, the inventor proposed a new technical solution that is different from the previous structure and has unpredictable effects. In addition, the present invention also specifically limits the use of dyes to be nanometer dyes, and its weight ratio to the base fabric is also specifically disclosed. Under the conditions in this range, excellent dyed fabrics can be dyed to achieve the effect of reducing the amount of dyes used. Furthermore, the present invention also discloses many relevant disclosures regarding the diameter ratio between the second section of the dye delivery pipeline and the steam delivery pipeline, or the preparation and processing conditions, so as to further improve the overall dyeing performance.

The above is only an illustration of a preferred embodiment in the scope of the patent application of the present invention, and is not intended to limit the scope of rights of the present invention based on the content of this embodiment; therefore, changes or modifications made without departing from the equivalent scope of the present invention should still be covered by the scope of the patent application of the present invention.
