[0001] The invention relates to the technical field of plant rubbing and dyeing, in particular to a high-temperature plant rubbing process. Background Art

[0002] Plant rubbing is a traditional handmade art that uses physical pressure to transfer the shape and color of plants to the target substrate. Plant rubbing requires certain skills, experience and aesthetics, and there may be problems such as unclear plant patterns, uneven colors, and inconsistent plant colors. Traditional methods include hammering, pressing or rolling with a wooden stick. Choosing the right tool is key. The color of plant rubbings will gradually oxidize and fade in direct sunlight or humid environments.

[0003] The defects of the existing high-temperature plant rubbing process are:

[0004] 1. In the application document CN111350087A, the main consideration was how to improve the efficiency and safety of fabric dyeing, but the problem that the colors of existing plant rubbings will gradually oxidize and fade in direct sunlight or in a humid environment was not considered;

[0005] 2. In the application document CN118461341A, the main consideration is how to improve the color fastness of fabric printing, and the problem of poor dyeing effect of existing plant rubbings is not taken into account;

[0006] 3. In the application document CN112726235A, a fixing composition is used to prevent the dye from falling off from the cotton grey cloth during subsequent use. However, it is not considered that most of the existing plant rubbings are two-dimensional rubbings, and the fabric layering is not rich. Summary of the invention

[0007] The object of the present invention is to provide a high-temperature plant rubbing process to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: a high-temperature plant rubbing process, the high-temperature plant rubbing process is as follows:

[0009] S1. Pick fresh plant stems and leaves, wash them with water, put them into water containing alum, soak them at room temperature for 2 hours, and the amount of alum added is 5g / L;

[0010] S2. Use chemical additives to pre-treat the fabric to make it suitable for rubbing;

[0011] S3. When rubbing, first spread a layer of oil paper of the same size as the fabric on a flat table, then spread a layer of processed fabric on the oil paper, and place the soaked plant stems and leaves on the fabric according to the designed pattern, and then cover the plants with a layer of fabric;

[0012] S4. Place the rolled fabric into a dedicated steaming box, and the high-temperature steam enables the shape, texture, and color of the plant to be transferred onto the fabric.

[0013] S5. After the steaming is completed, take out the rolled object for cooling. After cooling to room temperature, remove the plant stems and leaves placed on the fabric surface.

[0014] S6. Conduct a water wash to remove the excess chemical auxiliaries and plant impurities, and then drain the water.

[0015] S7. Dehydrate again after draining the water.

[0016] S8. Finally, put the fabric into a dryer and dry it at 85 degrees for 20 minutes. After taking it out of the cylinder, a finished fabric with a high-quality plant printing effect is obtained.

[0017] Preferably, in S2, the chemical auxiliary is alum. Add alum to water, stir evenly, put the fabric into it, soak it at room temperature, and then use a dehydration device to dehydrate it. At this time, the moisture content of the fabric is 100%.

[0018] Preferably, before printing, place the fabric on a flat tabletop, rub and stretch the fabric with both hands or use a wooden board with raised patterns to press the fabric to adjust the arrangement direction and tightness of the fabric fibers.

[0019] Preferably, the addition amount of alum is 5 g / L, the soaking time is 20 minutes, the rotation speed of the dehydration device is 350 revolutions per minute, and the dehydration time is 30 seconds.

[0020] Preferably, in S3, it further includes: place the paper core at one end of the fabric, then roll up the fabric and the plant tightly on the paper core, wind it tightly with a cloth strip, and tie a tight knot at the oiled paper at both ends.

[0021] Preferably, in S4, the temperature is 98 degrees and the steaming time is 60 minutes.

[0022] Preferably, in S5, after cooling, carefully remove the cloth strip and the paper core.

[0023] Preferably, in S6, wash it at room temperature in water for 5 minutes, and the bath ratio is 1:25.

[0024] Preferably, in S7, for the dehydration operation, use a dehydration device to dehydrate at a rotation speed of 1200 revolutions per minute for 2 minutes.

[0025] Preferably, in S8, it further includes blowing cold air appropriately during the drying process.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. The present invention processes the picked plant stems, leaves and fabrics with chemical aids, and places them in a high-temperature device to transfer the shape, texture and color of the plants onto the fabrics. It can effectively control color transfer. The special material treatment method and the high-temperature steaming and transfer printing process method can reduce traditional physical knocking and rolling, making the effect and color of plant rubbing more durable.

[0028] 2. When steaming, the present invention places the paper core at one end of the fabric, rolls the fabric and the plant tightly on the paper core, and winds it tightly with a cloth strip. In particular, the cloth strip should be tied tightly at the oil paper at both ends to ensure that the steam can only act between the fabric and the plant layer. To a certain extent, this can make the shape and texture of the plant be imprinted more deeply on the fabric. At the same time, due to the action of chemical aids, the fabric has different adsorption and presentation effects on the color and texture of the plant, thus enriching the layering of the fabric and forming a unique three-dimensional effect.

[0029] 3. By reasonably controlling the treatment method after plant picking, the degree of dehydration and the matching of the moisture content with the fabric, the present invention can maintain a moisture dynamic balance beneficial to color transfer and stability during the steaming process, ensure that the color change of the rubbing effect meets the expectations, and obtain high-quality plant rubbing finished products. At the same time, by adjusting the arrangement direction and tightness of the fabric fibers, the depth of penetration of plant pigments during rubbing is changed, so that the plant pattern not only presents a two-dimensional pattern during rubbing, but also can extend in the three-dimensional direction by means of folds or imprinted textures, greatly enriching the layering and artistic effect of the fabric.

[0030] 4. The present invention pretreats the fabric by selecting alum. When alum comes into contact with the fabric, it will undergo a chemical reaction with the surface of the fabric fibers, forming a thin covering layer on the fiber surface, changing the charge distribution and physical properties of the fiber surface. This covering layer changes the frictional force and interaction force between the fabric fibers, thus affecting the flatness and softness of the fabric, and providing more attachment points and performance spaces for the shape and texture of the plant during the rubbing process.

[0034] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figure 1 , an embodiment provided by the present invention: a high-temperature plant stamping process. The high-temperature plant stamping process is as follows:

[0036] S1. Pick fresh plant stems and leaves, wash them with water, and then put them into water containing ferrous sulfate. Soak them at room temperature for 2 hours, and the addition amount of ferrous sulfate is 5 g / L.

[0037] S2. Pretreat the fabric with chemical auxiliaries to make the fabric reach a state suitable for stamping.

[0038] S3. During the stamping operation, first lay a layer of oil paper on a flat tabletop, which is the same size as the fabric. Then lay a layer of the treated fabric flat on the oil paper. According to the designed flower pattern, place the soaked plant stems and leaves on the fabric according to the flower pattern design, and then cover a layer of fabric on the plants.

[0039] S4. Put the rolled-up fabric into a special steaming box. The high-temperature steam enables the shape, texture, and color of the plants to be transferred to the fabric. The temperature is 98 degrees, and the steaming time is 60 minutes.

[0040] S5. After the steaming is completed, take out the rolled-up object and cool it. After cooling to room temperature, carefully remove the cloth strips and paper cores, and remove the plant stems and leaves placed on the cloth surface.

[0041] S6. Conduct a water wash to remove excess chemical auxiliaries and plant impurities, and then drain the water. Rinse at room temperature in the water for 5 minutes, and the bath ratio is 1:25.

[0042] S7. After draining the water, dehydrate again. Use a dehydration device to dehydrate at a speed of 1200 revolutions per minute for 2 minutes.

[0043] S8. Finally, put the fabric into a dryer and dry it at 85 degrees for 20 minutes. During the drying process, blow cold air appropriately. After taking it out of the cylinder, a finished fabric with a high-quality plant stamping effect is obtained.

[0044] Further, before rubbing, first pick fresh plant stems and leaves, such as grass leaves, wash them clean with water to remove surface impurities, and then put them into water containing 5 g / L of ferrous sulfate, soak at room temperature for 2 hours to allow the plants to fully absorb the auxiliaries. Ferrous sulfate can react with components such as natural pigments in the plants, making the pigments more stable and less likely to be lost during subsequent processing and use. At the same time, controlling the soaking time can not only allow the plants to fully absorb the auxiliaries, but also avoid over-soaking, which may damage the plant tissues and affect the transfer effect of color and shape. Then, pre-treat the fabric. Add 5 g / L of alum to water, stir evenly and put the fabric into it, soak at room temperature for 20 minutes. After soaking, use a dehydration device to dehydrate at a speed of 350 revolutions per minute for 30 seconds. At this time, the moisture content of the fabric is about 100%, reaching a state suitable for rubbing.

[0045] During the rubbing operation, first lay a layer of oil paper on a flat table that is the same size as the fabric. The oil paper can prevent steam and color from penetrating to the outside, ensuring that the steam acts fully between the fabric and the plant layer. Lay a layer of pre-treated fabric flat on the oil paper. According to the designed flower pattern, place the soaked plant stems and leaves on the fabric in a certain shape and layout. Then cover another layer of fabric on the plants. Next, place a paper core at one end of the fabric, roll the fabric and the plants tightly around the paper core, and tie it tightly with a cloth strip. Especially, tie a tight knot with the cloth strip at the two ends of the oil paper to ensure that the steam can only act between the fabric and the plant layer, so that the plants are in close contact with the fabric during the high-temperature steam steaming process, ensuring that the shape, texture, and color of the plants are fully transferred to the fabric, and the transfer effect is more uniform and stable. Then put the rolled and tied fabric into a special steamer, set the temperature to 98 degrees, and steam for 60 minutes. During this process, the high-temperature steam enables the shape, texture, and color of the plants to be better transferred to the fabric through the action of chemical auxiliaries, and at the same time promotes the plant pattern to extend in the three-dimensional direction, enriching the fabric layering. After steaming, take out the rolled and tied object for cooling.

[0046] After cooling to room temperature, carefully remove the cloth strip and the paper core, and remove the plant stems and leaves placed on the fabric. Then carry out water washing, wash at room temperature in water for 5 minutes, avoid over-washing that may cause color fading, with a bath ratio of 1:25, fully wash away the excess auxiliaries and possible residual plant impurities. After that, carry out softening treatment, which can improve the fabric hand feeling without affecting the durability of the rubbing effect. Then drain the water, and dehydrate again after draining. Use a dehydration device to dehydrate at a speed of 1200 revolutions per minute for 2 minutes to further reduce the moisture content of the fabric. Finally, put the fabric into a dryer, dry at 85 degrees for 20 minutes, and blow cold air appropriately during the drying process to make the fabric dry evenly, avoiding damage to the color and texture caused by local overheating or over-drying, further ensuring the rubbing effect and the durability of the color, and obtaining a finished fabric with high-quality plant rubbing effect after taking it out of the tank.

[0047] Please refer to Figure 1, An embodiment provided by the present invention: A high-temperature plant stamping process. In S2, the chemical auxiliary is alum. Alum is added to water, stirred evenly, and then the fabric is put in. After soaking at room temperature, a dehydration device is used for dehydration. At this time, the moisture content of the fabric is 100%, the addition amount of alum is 5 g / L, the soaking time is 20 minutes, the rotation speed of the dehydration device is 350 revolutions per minute, and the dehydration time is 30 seconds.

[0048] Furthermore, when the fabric is soaked in an aqueous solution containing alum, the metal ions of alum will undergo chemical reactions with some groups on the surface of the fabric fibers, forming chemical bonding or physical adsorption. This combination changes the chemical environment on the surface of the fabric fibers, making them have a stronger affinity for plant pigments. In the subsequent steaming process, the pigments in the plants are more easily adsorbed onto the fabric treated with alum, thereby improving the vividness and depth of the stamped color, making the color more intense and full. In addition to adsorbing pigments, alum can also promote the fixation of pigments on the fabric. Further chemical reactions may occur between it and the pigment molecules to form relatively stable compounds or complexes. After the plant stamping is completed, whether it is washing, rubbing during daily use, or under the influence of environmental factors such as light, the pigments are not easily detached or faded from the fabric, greatly improving the durability of the stamped color and enabling the patterns of plant stamping to remain vivid and clear for a long time. After the fabric is treated with alum, its absorption and transmission properties of steam will also change. During the steaming process, the steam can penetrate more evenly in the fabric. The even steam penetration helps the plant pigments to diffuse and transfer more evenly on the fabric, avoiding uneven color situations. At the same time, the good penetration of steam in the fabric also promotes the shape and texture of the plant to be better imprinted on the fabric, enabling the plant pattern to be presented more completely and accurately, and to a certain extent, helping the plant pattern to extend in the three-dimensional direction, enhancing the three-dimensional sense and layering of the stamping effect. By using alum to treat the fabric and controlling steps such as soaking and dehydration, the effect of plant stamping can be optimized in multiple aspects, improving product quality and making the plant stamping process more practical and artistic.

[0049] When the plant and the fabric are combined, their moisture contents affect each other. If the water content of the plant is too high and the moisture content of the fabric is also high, during the steaming process, too much water will make the steaming environment too humid, affecting the penetration and adsorption of pigments. At this time, the pigments in the plant may diffuse unevenly in a large amount of water, resulting in mottled and blurred stamped colors. On the contrary, if the water content of the plant is too low and the moisture content of the fabric is relatively high, the plant may absorb too much water from the fabric during steaming, causing changes in cell structure and affecting pigment release, making the stamped color lighter or showing color differences. Therefore, it is necessary to reasonably control the moisture content of the fabric according to the dehydration degree of the plant, so that the two reach a relatively balanced moisture state during the steaming process, which is conducive to the uniform and stable transfer of pigments from the plant to the fabric, thereby obtaining an ideal stamping color effect.

[0050] During the steaming process, high-temperature steam will further change the moisture in plants and fabrics. The moisture in plants will be gradually released with the action of steam, and they will also absorb the moisture in the steam. The fabrics will also have the same moisture exchange process. If the initial moisture content of the plants is not properly controlled, they may not be able to adapt to the dynamic changes in moisture in the steam environment during steaming. If the water content of the plants is too high, a large amount of water will be released at the beginning of steaming, which may disperse the pigments that have been transferred to the fabrics, making the colors lighter or blurred; while the water content of the plants is too low, they may not be able to fully absorb the moisture in the steam during the steaming process to promote the release of pigments, resulting in dull rubbing colors. Therefore, by reasonably controlling the treatment method of plants after picking, the degree of dehydration, and the matching with the moisture content of the fabrics, a dynamic moisture balance that is conducive to color transfer and stability can be maintained during the steaming process, ensuring that the color changes of the rubbing effect meet expectations and obtaining high-quality plant rubbing products.

[0051] See also Figure 1 , an embodiment provided by the present invention: a high-temperature plant rubbing process, before rubbing, the fabric is placed on a flat table, rubbed and stretched with both hands or the fabric is pressed with a wooden board with raised patterns to adjust the arrangement direction and tightness of the fabric fibers.

[0052] Furthermore, the fabric is placed on a flat table and rubbed with both hands. The whole fabric can be rubbed together or partially rubbed, so as to change the arrangement direction and tightness of the fabric fibers. The rubbed fabric fibers become more disordered and form irregular textures. This makes the color of the plant penetrate and distribute along the texture produced by rubbing during the rubbing process. In the area where the fibers are rubbed more tightly, the pigment penetrates less and the color is lighter, while in the area where the fibers are looser, the pigment penetrates more easily and the color is darker, which increases the layering of the fabric. The fabric is stretched in different directions, such as horizontal, vertical or diagonal directions. The degree of stretching can be adjusted as needed to make the fabric fibers elongated and thinner. In the area with a larger degree of stretching, the plant color becomes lighter and the distribution is more sparse, because the distance between the fibers increases and the pigment penetration is relatively difficult; while the area without stretching or with a small degree of stretching has a darker and denser color. At the same time, when the shape of the plant is rubbed on the rubbed or stretched fabric, it will show distortion, deformation and other effects as the fabric deforms, which helps the plant pattern to extend in a three-dimensional direction, making the rubbing effect more vivid and natural.

[0053] It is also possible to use patterned wooden boards, metal plates, or special texture molds, etc. Place the fabric flat on the textured object, then press a heavy object on the fabric, or make the fabric come into close contact with the textured object through mechanical pressure to imprint the texture onto the fabric. After imprinting, the surface of the fabric has the same texture as the imprinting object. During plant stamping, the shape and color of the plant will intertwine with these textures. For example, when using a wooden board with raised patterns to imprint the fabric, during the steaming process, the plant pigments will form different deposition effects at the raised and sunken parts of the patterns. The color at the raised parts is lighter, and the color at the sunken parts is darker, creating a three-dimensional effect. Moreover, the shape of the plant will stretch and deform along the imprinted texture, enabling the plant pattern to not only present a two-dimensional pattern during stamping but also extend in the three-dimensional direction with the help of the imprinted texture, greatly enriching the layering and artistic effect of the fabric.

[0054] Please refer to Figure 1 , an embodiment provided by the present invention: a high-temperature plant stamping process. In S3, it further includes: placing the paper core at one end of the fabric, then tightly rolling the fabric and the plant around the paper core, winding it tightly with a cloth strip, and tying a tight knot at the oiled paper at both ends.

[0055] Furthermore, during the steaming process, the high-temperature steam is the key factor for transferring the color, shape, and texture of the plant onto the fabric. Through the operation of tightly rolling, the plant and the fabric can maintain a close fitting state. The pigments in the plant are more likely to penetrate into the fabric fibers under the action of the steam, and the texture of the plant can be more clearly imprinted on the fabric. For example, fine structures such as the veins and petal edges of the plant can be more accurately presented on the fabric in the case of close contact, making the stamped pattern more delicate and realistic. At the same time, close contact helps to achieve the uniformity of color transfer and can, to a certain extent, avoid the situation where uneven deposition of pigments on the fabric due to uneven action of steam in local areas results in patches of different shades of color, thereby improving the stamping quality.

[0056] Tying a tight knot at the oiled paper at both ends can effectively prevent the steam from escaping. The steam is restricted inside the rolled fabric and plant layer, making it act concentratedly between the plant and the fabric. This can not only improve the utilization efficiency of the steam, enabling the steam to fully play its role in a limited space, but also enhance the transfer effect of color and texture.

[0057] By restricting the steam range, the relative stability of the internal temperature and humidity can be maintained. Under suitable temperature and humidity conditions, the release, transfer, and combination of plant pigments with the fabric can proceed more smoothly, helping to obtain a consistent stamping effect. At the same time, a stable environment is also conducive to the fixation of the plant shape and texture on the fabric, making the stamped pattern clearer and more durable.

[0058] The operations of winding and coiling cause the fabric and the plant to form a certain curved and wrapped state around the paper core, generating a distribution of pressure and tension. During the steaming process, this pressure and tension will change with the action of steam, prompting the shape and texture of the plant to form a three-dimensional effect on the fabric. For example, the flower part of the plant may slightly bulge the fabric under pressure, while the stem forms a depression, thus making the plant pattern present a three-dimensional sense on the fabric. Moreover, the differences in pressure and tension in different parts contribute to the natural extension of the plant pattern in the three-dimensional direction, increasing the artistic appeal of the rubbing works. Winding and tying the cloth strips can fix the shape of the fabric, preventing the fabric from loosening or shifting during the steaming process. This can ensure that the relative position and contact state between the plant and the fabric remain unchanged, enabling the color, shape, and texture of the plant to be accurately transferred to the fabric and stably presented in the three-dimensional direction, reducing the situation where the movement of the fabric damages the fitting relationship between the plant and the fabric, thereby causing the rubbing pattern to be blurred or deformed and affecting the final rubbing effect.

[0059] Please refer to Figure 2 and Figure 3 , this application provides Experimental Example 1:

[0060] Compare the traditional knocking method with the new process: Select the same plant samples such as fresh maple leaves and fabric. The fabric is white pure cotton cloth. Cut the fabric into several pieces of the same size and mark them as the experimental group and the control group respectively.

[0061] Fabric of the experimental group: The picked maple leaves are washed and soaked in water containing 5 g / L of copperas at room temperature for 2 hours. At the same time, the fabric is soaked in water containing 5 g / L of alum at room temperature for 20 minutes and then dehydrated to a moisture content of about 100%. Place the treated maple leaves on the fabric according to the flower shape, lay oil paper and roll them up, put them into a steamer at 98 degrees and steam for 60 minutes. After cooling, remove the thread and wash, dehydrate, and dry.

[0062] Fabric of the control group uses the traditional knocking method: Place the fresh maple leaves directly on the fabric and repeatedly knock them with a hammer until the color and shape transfer is considered ideal, and then wash and dry them.

[0063] Color vividness: The rubbing pattern of the maple leaves in the experimental group has bright and uniform colors. The color of the red maple leaves is rich and full, and there is almost no situation of uneven color depth. While the color of the control group is relatively light, and the color is uneven at the knocking edge, with some areas being too light or too dark, and even color spots appear due to uneven knocking force.

[0064] Pattern clarity: The veins of the maple leaves in the experimental group are clearly visible, the leaf shape is complete, the edges are sharp, and the overall pattern has a strong three-dimensional sense, as if the maple leaves are truly attached to the fabric. The veins of the control group are partially blurred, the edges of the leaves have frayed edges and deformation, and the overall pattern appears flat and lacks a three-dimensional sense.

[0065] Color fastness: Two sets of printed fabrics were placed in direct sunlight for 30 days. The color of the experimental group only faded slightly, but the pattern was still clearly distinguishable; the color of the control group faded significantly, the pattern became blurred, and the color in some areas almost disappeared.

[0066] Experimental Example 2:

[0067] A single plant and the same kind of fabric, such as white cotton cloth, were selected. Multiple experimental groups were set up, and parameters such as steaming temperature, time, and plant soaking time in the process were changed respectively. At the same time, a control group was set up to print using the traditional rolling method.

[0068] Effect of steaming temperature:

[0069] Experimental Group 1: Steaming temperature is 90 degrees, and other parameters are normal;

[0070] The color of the plant pattern is relatively light, the texture of the petals is not clear enough, and the three-dimensional sense is insufficient, indicating that when the temperature is low, the release and transfer of plant pigments are incomplete.

[0071] Experimental Group 2: Steaming temperature is 105 degrees, and other parameters are normal;

[0072] The color is too bright, there is a bleeding phenomenon in the color of some stems and leaves, and the edge of the pattern is not clear enough, indicating that too high a temperature may cause excessive exudation and diffusion of pigments.

[0073] Effect of steaming time:

[0074] Experimental Group 3: Steaming time is 45 minutes, and other parameters are normal;

[0075] The color of the plant pattern is relatively light, the shape and texture are not clear enough, indicating that the steaming time is insufficient and the transfer of plant pigments is not sufficient.

[0076] Experimental Group 4: Steaming time is 75 minutes, and other parameters are normal;

[0077] Although the color is deep, there are slight color spots, and the edge of the pattern is blurred. Too long steaming time leads to uneven distribution of pigments.

[0078] Effect of plant soaking time:

[0079] Experimental Group 5: Plant soaking time is 1 hour, and other parameters are normal;

[0080] The color of the rose pattern is relatively light, and the texture is not delicate enough. It may be that the soaking time is short, and the plant cells do not fully absorb the additives, affecting the release of pigments.

[0081] Experimental Group 6: Plant soaking time is 3 hours, and other parameters are normal;

[0082] The color is too dark and uneven, and some petals are soft and rotten, affecting the integrity of the pattern, indicating that too long soaking time has an adverse effect on the plant structure and pigment stability.

[0083] Experimental group 7: The steaming temperature is 98 degrees, the steaming time is 60 minutes, the plant is soaked for 2 hours, and other parameters are normal;

[0084] The color vividness, pattern clarity and three-dimensional sense all reach good effects.

[0085] For the plants with patterns in the control group using the traditional rolling method, the color is uneven, the stems and leaves are severely deformed, and the texture is almost invisible.

[0086] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
