Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing, and in particular to a method for comprehensive dyeing and transfer printing of overlapping and layered patterns. Background Art

[0002] Traditional plant-based dyeing dates back thousands of years to ancient times, when people used natural plants such as madder, locust, agarwood, mulberry, and indigo to dye fabrics. These plant-based dyeing techniques have gradually developed and improved. With the development of industrialization and the emergence of chemical dyes, traditional plant-based dyeing has been significantly impacted. However, as people gradually realize the environmentally friendly, health-friendly, and culturally valuable benefits of traditional plant-based dyeing, it has garnered renewed attention in recent years. Traditional plant-based dyeing is used in clothing, textiles, gardening, and other fields, preserving traditional techniques while meeting modern environmental standards. However, compared to chemical dyes, current plant-based dyeing techniques produce darker, deeper colors that lack vividness. Furthermore, compared to chemical dyeing, plant-based dyeing produces relatively monotonous patterns and lacks a sense of depth, resulting in a poor visual quality for plant-based dyed fabrics.

[0003] Therefore, how to improve plant dyeing technology to obtain plant-dyed fabrics with bright colors, diverse patterns and rich color layers is a problem that needs to be solved at present. Summary of the Invention

[0052] Reference Figure 1 The embodiment of the present invention provides a method for comprehensive dyeing and transfer of overlapping and layered patterns, comprising the following steps S1-S5:

[0053] S1: Pretreating the fabric to be printed and dyed with potassium hydrogen tartrate to obtain a first fabric.

[0054] The method comprises the following steps: selecting a fabric to be printed and dyed, wherein the fabric to be printed and dyed is a wool and silk interwoven fabric obtained by yarn extraction using a cloth drawing method, and extracting part of the silk yarn from the fabric using the cloth drawing method (the wool yarn is retained and part of the silk yarn is extracted), so that different gloss colors can be obtained in the later printing and dyeing, so that the dyed fabric can obtain colors with different gloss and transparency under light, thereby increasing the richness of the color after the fabric is dyed and the layering of the pattern, and forming a superimposed color effect; using the wool and silk interwoven fabric as the fabric to be printed and dyed increases the color brightness of the printed and dyed fabric; soaking the fabric to be printed and dyed in a preset water temperature, and After a long time, potassium hydrogen tartrate is added and soaked for a preset time to obtain a pretreated first fabric, wherein potassium hydrogen tartrate is used to soak the fabric to be printed and dyed. Potassium hydrogen tartrate is easily soluble in hot water but insoluble in ethanol. When extracting some dyes, such as using comfrey, ethanol needs to be added to obtain a dye solution with higher purity. Therefore, the fabric fluffing agent and softener must be insoluble in ethanol to play their role. If tartaric acid is used for the operation, tartaric acid is soluble in ethanol and cannot achieve the above effect; potassium hydrogen tartrate will adhere to the plant fiber during the soaking process, and produce a chemical reaction after meeting the plant tannin, which is beneficial to improve the brightness of the plant dyed color.

[0055] S2: Pre-treating the plants to be printed and dyed with the potassium hydrogen tartrate to obtain the printed and dyed plants.

[0056] When performing plant transfer, the plants to be printed and dyed need to be pretreated first, wherein different plants have different treatment methods. For example, some plants to be printed and dyed need to be soaked in ethanol, alum solution and potassium hydrogen tartrate in sequence, and the treatment steps include: soaking the plants to be printed and dyed with ethanol to obtain a first treated plant, then soaking the first treated plant in an alum solution, and adding potassium hydrogen tartrate for soaking after a second period of time, wherein potassium hydrogen tartrate is selected instead of tartaric acid because potassium hydrogen tartrate is easily soluble in hot water and completely insoluble in ethanol, and can be mixed with ethanol; tartaric acid is soluble in ethanol and therefore cannot play its role; adding potassium hydrogen tartrate is conducive to making the pattern transferred on the fabric more vivid in color, more clear in shape, and more distinct in layering, thereby obtaining a printed and dyed plant; while another part of the plants to be printed and dyed only need to be treated with alum and potassium hydrogen tartrate, and the treatment steps include: soaking the plants to be printed and dyed in an alum solution, and adding the potassium hydrogen tartrate for soaking after a second period of time to obtain a printed and dyed plant.

[0057] S3: using the printing and dyeing plant to perform base color printing and dyeing on the first fabric to obtain a plant-dyed fabric.

[0058] After obtaining a first fabric and a printing and dyeing plant, the printing and dyeing plant is used to perform base color printing and dyeing on the first fabric to obtain a plant-dyed fabric. Specifically, a color liquid for printing and dyeing is extracted from the printing and dyeing plant, the color liquid is diluted with ethanol to form a color liquid solution, and the first fabric is immersed in the color liquid solution to obtain a first printed and dyed fabric. The first printed and dyed fabric is then treated with an alum solution and air-dried in the shade to obtain a plant-dyed fabric with a base color printed on it.

[0059] S4: performing plant thermal transfer printing on the plant-dyed fabric based on a mesh mold to obtain a multi-color printed fabric.

[0060] The plant-dyed fabric is subjected to plant thermal transfer printing based on a mesh mold. Specifically, the printed plants are placed on the plant-dyed fabric according to a preset image and covered with plastic wrap to obtain a covered fabric; the covered fabric is rolled up using a cylindrical stick to obtain a first rolled fabric; the first rolled fabric is rolled and pressed using a soft mesh mold, wherein when rolling and pressing using a soft mesh mold, the fabric is first laid flat so that wrinkles cannot be formed, and when rolling and pressing the fabric, the fabric is first rolled up and then dragged in another direction to ensure a certain pressure and the flatness of the plant, thereby making the plant pattern clearer, the background color more uniform, and the overall layering rich, thereby obtaining a second rolled fabric; the second rolled fabric is wrapped with plastic wrap and placed in an electric steamer for steam heating. After steaming for the sixth time, it is taken out and placed for the seventh time, and the wrapped plastic wrap is then unwound to obtain a multi-color printed and dyed fabric.

[0061] S5: Embroidery dyeing is performed on the multi-color printed fabric to obtain a three-dimensional printed fabric.

[0062] After heat-transferring the plant-dyed fabric using a mesh mold to produce a multi-color printed fabric, the multi-color printed fabric is then embroidered. Specifically, a sketch of the main plant pattern is drawn around the main plant pattern on the multi-color printed fabric. A shape identical to the main plant pattern is embroidered based on the sketch to produce a three-dimensional printed fabric. This three-dimensional printed fabric features vibrant colors, diverse patterns, and a rich sense of layering, enhancing the visual appeal of the plant-dyed fabric.

[0063] The present embodiment provides a method for transferring a comprehensive plant dyeing pattern of overlapping colors and layers, wherein potassium hydrogen tartrate is used to pre-treat a to-be-printed and dyed fabric to obtain a first fabric, wherein potassium hydrogen tartrate adheres to plant fibers during the soaking process and produces a chemical reaction with plant tannins, which is beneficial to improving the brightness of the plant dyeing color; potassium hydrogen tartrate is used to pre-treat a to-be-printed and dyed plant to obtain a printed and dyed plant, wherein the addition of potassium hydrogen tartrate for soaking is beneficial to making the color of the pattern transferred to the fabric more vivid, the shape more clear, and the layers more distinct; the printing and dyeing plant is used to perform a base color treatment on the first fabric. Printing and dyeing, so that the first fabric is evenly impregnated with the background color, and a plant-dyed fabric with uniform background color printing and dyeing is obtained; based on a mesh mold, the plant-dyed fabric is subjected to plant heat transfer printing, wherein the use of a mesh mold for transfer printing can make the plant pattern clearer, the background color more uniform, and the overall layered feeling, thereby obtaining a stacked color printed and dyed fabric; embroidery dyeing is performed on the stacked color printed and dyed fabric, wherein embroidery dyeing is conducive to increasing the layered feeling and three-dimensional sense of the pattern printed and dyed on the fabric, thereby obtaining a three-dimensional printed and dyed fabric, which has bright colors, diversified patterns, and rich layered colors, thereby improving the appearance of the plant-dyed fabric. The above-mentioned printing and dyeing technology is more environmentally friendly than the chemical dye printing and dyeing method, and the plant printing and dyeing method has rich cultural value. The printed plants are brightly colored, the patterns are diversified, and the visual perception is high, thereby optimizing the plant printing and dyeing technology.

[0064] Reference Figure 2 In one embodiment, the above-mentioned method of pre-treating the fabric to be printed and dyed with potassium hydrogen tartrate to obtain a first fabric comprises:

[0065] S11. Selecting a fabric to be printed and dyed, wherein the fabric to be printed and dyed is a wool and silk interwoven fabric obtained by yarn extraction using a cloth drawing method.

[0066] The fabric to be printed and dyed is a fabric interwoven with wool and silk. The protein fiber of wool can better absorb plant pigments to make the printed and dyed patterns clearer. Silk can enhance the saturation and brightness of plant colors. The cloth drawing method is used to partially extract the silk yarn of the fabric, retain the wool yarn, and extract part of the silk yarn so that the count density ratio of the retained silk yarn is about 1:2:4. The extraction of silk yarn can obtain colors with different glosses in the later printing and dyeing. The colors of the high-density parts will be bright and the patterns will be more specific and clear. The colors of the low-density parts will be more transparent and the patterns will be more abstract. This treatment makes the dyed fabric obtain colors of different purity and transparency under the light, increases the richness of the colors after the fabric is dyed, and the pattern will be more layered, eventually forming a overlapping color gradient and flashing effect.

[0067] S12, soaking the fabric to be printed and dyed in water at a preset temperature, and adding potassium hydrogen tartrate after the first time and soaking for a preset time to obtain a pretreated first fabric.

[0068] The fabric to be printed and dyed is soaked in a preset water temperature, wherein the preset water temperature is 95±2°C, and soaked in the water temperature of 95±2°C for a first time, which is 3 hours. After soaking for 3 hours, potassium hydrogen tartrate (chemical formula: C4H5KO6) is added and soaked for a preset time, which is preferably 3 hours. Potassium hydrogen tartrate is easily soluble in hot water but insoluble in ethanol. When extracting some dyes, such as using comfrey, ethanol needs to be added to obtain a dye solution with higher purity. Therefore, the fabric bulking agent and softener must be insoluble in ethanol to play their role. If tartaric acid is used for the operation, tartaric acid is soluble in ethanol, which cannot achieve the above effect; wherein, the weight ratio of potassium hydrogen tartrate to water is 3:100. Potassium hydrogen tartrate will adhere to the plant fibers during the soaking process, and after meeting with plant tannins, a chemical reaction will occur, thereby improving the softness of the fabric and the brightness and light resistance of the plant-dyed colors.

[0069] As described above, the drawn fabric is selected as the fabric to be printed and dyed, and the fabric to be printed and dyed is a fabric interwoven with wool and silk. The protein fiber of wool can better absorb plant pigments to make the printed and dyed pattern clearer, and silk with different counts and densities can enhance the layering of the plant pattern and the multi-level brightness of the color; the fabric to be printed and dyed is soaked in a preset water temperature, wherein the preset water temperature is 95±2°C, and soaked in water at 95±2°C for a first time, which is 3 hours. After soaking for 3 hours, potassium hydrogen tartrate (chemical formula: C4H5KO6) is added and soaked for a preset time, which is preferably 3 hours, wherein the weight ratio of potassium hydrogen tartrate to water is 3:100. Potassium hydrogen tartrate will adhere to the plant fiber during the soaking process, and after meeting with plant tannins, a chemical reaction will occur, thereby improving the softness of the fabric and the brightness and light resistance of the plant-dyed color.

[0070] In one embodiment, the above-mentioned use of potassium hydrogen tartrate to pretreat the plant to be printed and dyed to obtain the printed and dyed plant comprises:

[0071] The plant to be dyed is soaked in an alum solution, and potassium hydrogen tartrate is added thereto for soaking after a second period of time to obtain the dyed plant.

[0072] As mentioned above, before using plants for fabric printing and dyeing, the plants to be printed and dyed need to be pretreated, and the plants to be printed and dyed include plants for base color printing and dyeing and / or plants for plant thermal transfer; wherein different plants have different treatment methods, for example, the pretreatment of some plants to be printed and dyed only requires soaking in alum solution and potassium hydrogen tartrate. Specifically, the plants to be printed and dyed are soaked in alum solution for 24 hours, and then potassium hydrogen tartrate is added for soaking, thereby obtaining printing and dyeing plants, wherein the weight ratio of potassium hydrogen tartrate to water is 1:100; if the plants to be printed and dyed are Lithospermum, etc., then its pretreatment step comprises: taking lithospermum treatment as an example, using ethanol to soak the plant to be printed and dyed (lithospermum), ethanol can increase the brightness of the color, and using ethanol to soak the plant can also increase the extraction amount of the plant dye solution, that is, if lithospermum is not soaked in ethanol, the extracted lithospermum color solution is light in color and impure in color, and it may even be impossible to extract the lithospermum color solution, thereby affecting the printing and dyeing of the fabric; and the lithospermum color solution extracted after soaking lithospermum in ethanol has bright color and high purity, which is beneficial to the printing and dyeing of the fabric. Specifically, when the lithospermum is subjected to dye solution extraction, the lithospermum is immersed in 9 The method comprises the following steps: soaking the dye in 5% alcohol for 5-10 hours (the alcohol does not cover the dye material), filtering out the dye liquor, and then adding room temperature water 3-5 times the weight of the dye liquor to dilute it to obtain a purple dye liquor; extracting the lithospermum dye liquor by the above-mentioned soaking method and the rubbing method, wherein the rubbing method comprises chopping the lithospermum and soaking it in clean water first, then adding 70-80°C hot water, rubbing the purple pigment by hand, and finally filtering out the dye liquor; the soaking method is simpler than the rubbing method in its processing operation, can effectively improve the processing efficiency of the dye liquor, and the rubbing method extracts the purple color liquid whose purity is not high, which is not conducive to the fabric Printing and dyeing; after treating with ethanol, soaking in an alum solution, and adding potassium hydrogen tartrate after a second period of time for soaking, thereby obtaining a printing and dyeing plant; wherein, potassium hydrogen tartrate is selected instead of tartaric acid because potassium hydrogen tartrate is completely insoluble in ethanol and can be mixed with ethanol, while tartaric acid is soluble in ethanol and cannot play its role; the second period of time is 24 hours, and the weight ratio of potassium hydrogen tartrate to water is 1:100. The addition of potassium hydrogen tartrate can make the fabric softer and make the color of the pattern transferred on the fabric more vivid, the shape more clear, and the layering more distinct.

[0073] Reference Figure 3 In one embodiment, before the above-mentioned use of the printing and dyeing plant to perform base color printing and dyeing on the first fabric to obtain the plant-dyed fabric, the process further includes:

[0074] S31, boiling the dyeing plant in water, and then simmering over low heat for a third time to obtain a first color solution.

[0075] The weight ratio of the printing and dyeing plants to water is 2:100; the third time length is preferably 20 minutes.

[0076] S32: Filter the first color liquid to obtain a first filtrate and a first filter residue.

[0077] S33, boiling the first filter residue in water, and then simmering over low heat for the third time to obtain a second color liquid.

[0078] S34, filtering the second color liquid to obtain a second filtrate.

[0079] S35. Mix the first filtrate and the second filtrate to obtain a color solution.

[0080] As described above, the dyeing plant is boiled in water, wherein the weight ratio of the dyeing plant to water is 2:100; then, the mixture is simmered over low heat for 20 minutes to obtain a first color liquid; the first color liquid is filtered to obtain a first filtrate and a first filter residue; then, the first filter residue is boiled in water, and then, the mixture is simmered over low heat for 20 minutes to obtain a second color liquid; the second color liquid is filtered to obtain a second filtrate; and the first filtrate and the second filtrate are mixed to obtain a final color liquid.

[0081] Reference Figure 4 In one embodiment, the above-mentioned use of the printing and dyeing plant to perform background dyeing on the first fabric includes:

[0082] S36, diluting the color solution with ethanol to obtain a color solution.

[0083] S37, immersing the first fabric in the color solution and heating and stirring the first fabric, taking out the first fabric after a fourth period of time, and washing with water to remove excess color solution on the first fabric, thereby obtaining a first printed and dyed fabric.

[0084] The fourth duration is preferably 20 minutes.

[0085] As described above, the color liquid is diluted with ethanol. Diluting the color liquid with ethanol is beneficial to making the color of the color liquid more vivid, wherein the weight ratio of the color liquid to ethanol is 2:7; the diluted color liquid is a color liquid solution; the first fabric is immersed in the color liquid solution for 20 minutes, and the color liquid solution is heated during the immersion to raise its temperature to 70°C. Heating the color liquid solution is beneficial to uniformly coloring the first fabric immersed in the dyeing. When immersing the first fabric, the first fabric should always be stirred in the color liquid solution, preferably 50 times per minute, to avoid bubbles between the fabric and the color liquid solution, resulting in uneven dyeing. After the immersion is completed, the excess color liquid solution on the immersed first fabric is washed with water to obtain a first printed and dyed fabric.

[0086] Reference Figure 5 In one embodiment, after obtaining the first printed and dyed fabric, the method further comprises:

[0087] S38, preparing alum solution according to a preset ratio.

[0088] The weight ratio of alum to water is 1:100; put alum into water at 40℃~50℃ and stir it thoroughly to dissolve it to obtain an alum solution.

[0089] S39, immersing the first printed and dyed fabric in the alum solution, heating the alum solution, and moving the first printed and dyed fabric to obtain a second printed and dyed fabric.

[0090] The first printed and dyed fabric is immersed in an alum solution (mordant solution) for about 20 minutes. During the immersion, the alum solution is heated to slowly raise its temperature to about 70°C to uniformly color the fabric. During the immersion, the first printed and dyed fabric is always stirred in the alum solution, preferably 50 times per minute, to avoid bubbles between the first printed and dyed fabric and the alum solution to obtain the second printed and dyed fabric.

[0091] S40, washing away excess alum solution on the second printed and dyed fabric, and drying at a set temperature to obtain a dried second printed and dyed fabric.

[0092] Since the amount of pigment absorbed by the fabric and thread during each dyeing process is limited, once saturated, no matter how many times the dye is applied, a good effect will not be achieved. In this case, the fabric needs to be dried first, and the pigment is fixed using the "drying method". The dried fabric is then allowed to absorb the pigment again. This involves washing away the excess alum solution from the second printed fabric and drying it at a set temperature of 10-20°C. After drying, the mordanting and drying steps are repeated to obtain a darker plant-dyed fabric.

[0093] As described above, an alum solution is prepared according to a preset ratio, that is, the weight ratio of alum to water is 1:100; alum is placed in water at a temperature of 40°C to 50°C and fully stirred to dissolve to obtain an alum solution; the first printed and dyed fabric is immersed in the alum solution (mordant solution) for about 20 minutes, and the alum solution is heated during the immersion to slowly raise its temperature to about 70°C so that the fabric is evenly colored. During the immersion, the first printed and dyed fabric is always stirred in the alum solution, preferably 50 times per minute, to avoid bubbles between the first printed and dyed fabric and the alum solution, to obtain a fourth printed and dyed fabric; the excess alum solution on the fourth printed and dyed fabric is washed off, and the fabric is dried at a set temperature to obtain a plant-dyed fabric; since the amount of pigment absorbed by the fabric and thread is limited during each immersion, once saturated, no good effect will be obtained no matter how many times the immersion is increased. In this case, if the fabric needs to be dyed a darker color, it is necessary to repeatedly dye the fabric using a dry method combined with the steps of plant dyeing and mordanting, that is, repeat the plant dyeing-mordanting-washing-drying operation steps 4 times, and use the dry method to dye the dark color to increase the color layering; specifically, since the amount of pigment absorbed by the fabric and thread during each immersion dyeing is limited, once saturated, no matter how many times it is added, a good effect will not be obtained. In this case, it is necessary to dry the fabric first, use the "drying method" to fix the pigment, and allow the dried fabric to absorb the pigment again; wherein, drying requires using a light-shielding drying device to dry at a low temperature of 10 to 20 degrees Celsius. After drying, the same method is used to extract the pigment from the dye material again to make a dye solution. The dried fabric is immersed in the dye solution and the dyeing and mordanting processes are repeated. After completing the drying process, the same process can be repeated multiple times to obtain a darker-dyed fabric (the second printed and dyed fabric).

[0094] In one embodiment, after obtaining the dried second printed and dyed fabric, the method further comprises:

[0095] The second printed and dyed fabric is soaked in a sodium carbonate solution for a fifth period of time, the second printed and dyed fabric is washed with clean water and then laid flat, the second printed and dyed fabric is hung up to dry in the shade, and then the second printed and dyed fabric is ironed to obtain a plant-dyed fabric with a fixed base color.

[0096] As mentioned above, some fabrics that have completed base color printing and dyeing need to further undergo base color fixing. For example, the fabric obtained with madder root as the dyeing material, the second printed and dyed fabric that has completed base color printing and dyeing is soaked in a sodium carbonate solution for a fifth period of time, wherein the weight ratio of sodium carbonate to water is 3:100, and the fifth period is 5-10 minutes. Soaking in sodium carbonate solution will increase the color saturation of the fabric by 2-3 times; after soaking in sodium carbonate solution, the second printed and dyed fabric is washed with clean water and then laid flat, and then the second printed and dyed fabric is hung up and dried in the shade, and then ironed with an iron after drying in the shade, wherein the ironing temperature needs to be controlled at about 30°C to avoid damaging the fabric, and the plant-dyed fabric with the base color fixed can be obtained by ironing.

[0098] S41, placing the printed and dyed plants on the plant-dyed fabric according to a preset image and covering it with a plastic wrap to obtain a covered fabric.

[0099] The preset image refers to a pre-designed pattern to be printed; the printed plants are placed on the first fabric according to the preset image and covered with plastic wrap, that is, the upper layer of the fabric is covered with plastic wrap equal to the area of ​​the fabric to avoid overlapping and blurring of the patterns, thereby obtaining a covered fabric.

[0100] S42, using a cylindrical stick to roll up the covering fabric to obtain a first rolled fabric.

[0101] The cylindrical stick is preferably a cylindrical stick of wooden material having a diameter of 5 cm and a length of 50 cm.

[0102] S43, using a soft mesh mold to roll and press the first rolled fabric to obtain a second rolled fabric.

[0103] The soft mesh mold is preferably one with mesh holes smaller than 0.1 mm. This soft mesh mold can not only evenly apply pressure to bind the fabric so that the fabric color can be evenly colored, but also the holes smaller than 0.1 mm can avoid leaving marks due to the small gaps, so that the fabric color can be evenly colored. When using the soft mesh mold to roll the first rolled fabric, a certain pressure should be applied to squeeze the printed and dyed plants placed on the first fabric. When using the soft mesh mold to roll and press, the fabric should first be laid flat to prevent wrinkles from forming. When rolling and pressing the fabric, the fabric should be rolled up first and then dragged in the other direction to ensure a certain pressure and the flatness of the plants, thereby making the plant pattern clearer, the base color more uniform, and the overall layering rich.

[0104] S44, wrapping the second rolled fabric with plastic wrap, and placing it in an electric steamer for steam heating, taking it out after steaming for a sixth time, and placing it for a seventh time, removing the wrapped plastic wrap to obtain a multi-color printed and dyed fabric.

[0105] Use plastic wrap to wrap the second roll of fabric. The plastic wrap isolates the fabric from the steam, ensuring that the fabric will not be corroded by the steam with a medium. In addition, the plastic wrap can also effectively prevent the colors of multiple pieces of fabric from bleeding into each other when heated at the same time, so that the colors of the fabrics maintain better brightness. Place the second roll of fabric wrapped with plastic wrap in an electric steamer for steam heating. Compared with the boiling method, the electric steamer does not come into contact with water, thus preventing water from coming into contact with plants, causing color difference between the outer and inner colors. In addition, the steam can heat evenly, making the colors and patterns of the fabrics more uniform and clear.

[0106] As described above, the printed and dyed plants are placed on the plant-dyed fabric according to a preset image and covered with plastic wrap to obtain a covered fabric, wherein the preset image refers to a pre-designed pattern to be printed and dyed; the printed and dyed plants are placed on the plant-dyed fabric according to a preset image and covered with plastic wrap, that is, the upper layer of the fabric is covered with plastic wrap that is the same size as the fabric area to avoid blurring due to overlapping patterns, thereby obtaining a covered fabric. Use a cylindrical stick to roll up the covering fabric, wherein the cylindrical stick is preferably a cylindrical wooden stick with a diameter of 5 cm and a length of 50 cm. Use the cylindrical wooden stick to roll up the covering fabric to obtain a first roll of fabric; then use a soft mesh mold to roll and press the first roll of fabric to obtain a second roll of fabric, wherein the soft mesh mold is preferably a soft mesh mold with mesh holes less than 0.1 mm. When using the soft mesh mold to roll and press the first roll of fabric, a certain pressure must be formed to squeeze the printed and dyed plants placed on the first fabric. When using the soft mesh mold to roll and press, first lay the fabric flat to prevent wrinkles from forming. When rolling and pressing the fabric, first roll up the fabric and then drag the fabric in another direction to ensure that a certain pressure and the flatness of the plant are formed, thereby making the plant pattern The pattern is clearer, the background color is more uniform, and the overall sense of hierarchy is achieved, thereby obtaining a second roll of fabric; finally, wrapping the second roll of fabric with plastic wrap, isolating the fabric from the steam, and ensuring that the fabric will not be eroded by the steam with a medium, and the plastic wrap can also effectively prevent the colors of multiple pieces of fabric from bleeding into each other when heated at the same time, thereby maintaining better brightness of the fabric color; placing the second roll of fabric wrapped with plastic wrap in an electric steamer for steaming, and taking it out after steaming for the sixth time and placing it for the seventh time, wherein the sixth time of steaming can be set according to actual needs and is not specifically limited, and the seventh time of placing it can also be set according to actual needs. The purpose of placing the steamed fabric for the seventh time is to cool it down and avoid burns; removing the wrapped plastic wrap can obtain the multi-color printed and dyed fabric.

[0107] Reference Figure 7 In one embodiment, the above-mentioned embroidery dyeing of the multi-color printed fabric to obtain a three-dimensional printed fabric includes:

[0108] S51, drawing a sketch of the main plant pattern around the main plant pattern on the double-color printed fabric.

[0109] S52: Embroidering a shape identical to the main plant pattern according to the sketch to obtain a three-dimensional printed fabric.

[0110] When embroidering the same shapes as the main plant pattern based on the sketch, the main stitches used are knitting needles, beading needles, interwoven stitches, and flat stitches. The stitches used are mainly flower stitches and random stitches. The embroidered pattern overlaps with the printed plant pattern, forming a multi-layered pattern with a two-dimensional and three-dimensional effect, which enhances the layering and three-dimensional effect of the printed fabric.
