Description

Technical Field

[0001] The present invention relates to the technical field of papermaking, and in particular to a method for producing paper for calligraphy and painting by combining woven and non-woven technologies. Background Art

[0002] Traditional Chinese paper for calligraphy and painting, typified by parchment, also includes bamboo paper, hemp paper, straw paper, and mixed paper. Through varying pulping methods and levels, different processing methods for the same raw material, and the blending of different raw materials, thousands of different paper products (mixed paper) can be produced from just a dozen raw materials. These materials vary in ink affinity, strength, tensile strength, color, and hydrophilicity. Xuan paper is the most representative of these, dominating the market share of traditional calligraphy and painting papers.

[0003] Traditional calligraphy and painting paper is a disordered non-woven structure, such as Figure 1 As shown, plant fiber raw materials are mechanically and chemically processed into dispersed fibers of relatively high purity. These fibers are then mixed with water to form a slurry. The slurry flows through a porous mold screen to filter out the water. The fibers form a wet film on the screen's surface. After drying, the film forms a strong sheet of cellulose fibers interwoven by hydrogen bonds. This sheet is used as a writing material. With the widespread introduction of Western painting in the early 20th century, a new genre of painting emerged in China: color ink painting, which combines traditional ink with mineral gouache pigments. This requires paper that can achieve the smudge effect of traditional brush and ink while also allowing for the overwriting and overlaying of mineral gouache pigments. Traditional calligraphy and painting paper is effective for the overwriting of ink, but lacks the strength and stress resistance to overwriting and overlaying gouache pigments, resulting in deformation, cracking, and holes. Gouache paper, while capable of overwriting and overlaying gouache pigments, lacks the ability to achieve the same smudge effect as traditional brush and ink. Summary of the Invention

[0004] In view of this, the present invention provides a method for producing calligraphy and painting paper that combines woven and non-woven technologies to solve the problem that traditional calligraphy and painting paper is effective for brush and ink blending, but lacks strength and stress for gouache paint modification and stacking, and is prone to deformation, cracking and holes, while gouache paper can meet the needs of gouache paint modification and stacking, but cannot reflect the blending effect of traditional brush and ink.

[0005] The present invention provides a method for producing calligraphy and painting paper by combining woven and non-woven technologies, comprising the following steps:

[0006] Selecting raw materials, and making them into slurry after pre-treatment, and adding water to dilute the slurry to prepare for spraying;

[0007] Select yarn with a thickness of 11-31tex and a twist of 45-80 twists / 10cm, and weave the yarn into a density of 28×24 strands / inch and a weight of 30-45g / m 2a base fabric having a plain weave;

[0008] Fix the base fabric on the papermaking mesh cage to ensure that the base fabric is flat;

[0009] Place the papermaking cage with the base fabric fixed on it at the bottom of the spraying machine, add the diluted slurry into the spraying machine, and make the spraying machine spray the slurry evenly on the base fabric;

[0010] The wet paper sheet with the base cloth is squeezed and dried to obtain a paper sheet with the slurry and the base cloth combined. The dried paper sheet is then trimmed and cut to obtain paper for calligraphy and painting.

[0011] In an optional embodiment, during the step of spraying the slurry evenly on the base fabric by the spraying machine, the papermaking mesh cage needs to be rotated to allow the slurry to be evenly deposited on the base fabric.

[0012] In an optional embodiment, when the papermaking mesh cage is rotated to evenly deposit the slurry on the base fabric, the moisture in the slurry will flow out from the mesh holes of the papermaking mesh cage due to gravity and the rotational force of the papermaking mesh cage, and the fibers in the slurry will be intertwined with the textile base fabric to initially form a paper sheet with a certain strength and thickness. After the slurry is evenly deposited on the base fabric, the rotation of the papermaking mesh cage is stopped and the spraying is stopped.

[0013] In an optional embodiment, after the papermaking cage stops rotating, the wet paper sheet with the base cloth is removed, and the wet paper sheet with the base cloth is pressed and dried in sequence.

[0014] In an optional embodiment, when drying the wet paper sheet, it is necessary to first determine the type and thickness of the paper sheet, and adjust the parameters of the drying equipment according to the type and thickness of the paper sheet.

[0015] In an optional embodiment, before the spraying machine sprays the slurry evenly on the base fabric, it is necessary to adjust the pressure, speed and spraying amount of the spraying according to the thickness and uniformity of the paper sheet to be produced.

[0016] In an optional embodiment, after placing the papermaking mesh cage with the base fabric fixed thereon at the bottom of the spraying machine, it is necessary to first adjust the distance between the spraying machine and the papermaking mesh cage so that the slurry can be evenly sprayed onto the base fabric.

[0017] In an optional embodiment, when water is added to dilute the slurry, the concentration thereof needs to be maintained between 5% and 10%.

[0018] In an optional embodiment, the raw materials are celtis sinensis bark and paddy rice straw.

[0019] In an optional embodiment, when selecting yarn, pure cotton yarn is selected.

[0020] Beneficial effects:

[0021] By adopting the production method disclosed in the present invention, calligraphy and painting paper with a textile base fabric as the base is produced, so that the calligraphy and painting paper has a double-layer structure of woven and non-woven. The plain weave structure can provide additional support for the paper pages, enhance the toughness, stress and strength of the paper pages. The calligraphy and painting paper produced by the production method in this embodiment combines woven and non-woven technologies, can effectively reduce the looseness problem caused by fiber aging, and extend the storage time of the calligraphy and painting paper. In addition, the calligraphy and painting paper has the special texture of the textile base fabric, which can bring new artistic expression to calligraphy and painting creation and improve the artistic effect.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] The following combination Figure 2 and Figure 3 , describing embodiments of the present invention.

[0028] According to an embodiment of the present invention, a method for producing calligraphy and painting paper combining woven and non-woven technologies is provided, comprising the following steps:

[0029] Raw materials are selected and pre-processed to prepare slurry, which is then diluted with water to prepare for spraying.

[0030] Specifically, high-quality celtis bark and paddy straw are first selected as the main raw materials. After pretreatment steps such as soaking, steaming, and bleaching, the raw materials are prepared into slurry. Then, the treated slurry is diluted with water to reduce the concentration of the slurry and facilitate the spraying operation.

[0031] Specifically, when water is added to dilute the slurry, the concentration needs to be maintained between 5% and 10%.

[0032] Preferably, in this embodiment, the concentration of the slurry is maintained at 7%. In other optional embodiments, the concentration of the slurry can be 5% or 10%.

[0033] Furthermore, yarns with a thickness of 11-31 tex and a twist of 45-80 twists / 10 cm are selected and woven into a yarn with a density of 28×24 strands / inch and a gram weight of 30-45 g / m 2 Base fabric with plain weave.

[0034] Specifically, when selecting yarn, choose pure cotton yarn.

[0035] Furthermore, the base fabric is fixed on the papermaking mesh cage to ensure that the base fabric is flat;

[0036] Specifically, the base fabric is laid on the end surface of the papermaking mesh cage and is made to fit the end surface of the papermaking mesh cage. The base fabric is then trimmed to ensure that the base fabric is flat to avoid uneven paper sheets caused by uneven base fabric.

[0037] Furthermore, the papermaking mesh cage with the base fabric fixed thereon is placed at the bottom of the spraying machine, and the diluted slurry is added into the spraying machine so that the spraying machine sprays the slurry evenly onto the base fabric.

[0038] Specifically, after placing the papermaking mesh cage with the base fabric fixed thereon at the bottom of the spraying machine, it is necessary to first adjust the distance between the spraying machine and the papermaking mesh cage so that the slurry can be evenly sprayed onto the base fabric.

[0039] Specifically, the spraying machine sprays the diluted slurry through a nozzle at a certain pressure and speed onto the base fabric of the papermaking mesh cage. During the slurry spraying process, the papermaking mesh cage needs to be rotated and rotated at a uniform speed so that the slurry is evenly sprayed and deposited on the base fabric.

[0040] Specifically, before the spraying machine sprays the slurry evenly onto the base fabric, the pressure, speed, and spraying volume of the spraying machine need to be adjusted according to the thickness and uniformity of the paper sheet to be produced.

[0041] Specifically, when the papermaking mesh is rotated to make the slurry evenly deposited on the base fabric, the water in the slurry will flow out from the mesh holes of the papermaking mesh due to gravity and the rotational force of the papermaking mesh, and the fibers in the slurry will be intertwined with the textile base fabric to initially form a paper sheet with a certain strength and thickness. After the slurry is evenly deposited on the base fabric, the rotation of the papermaking mesh is stopped and the spraying is stopped.

[0042] Furthermore, the wet paper sheets with the base cloth are pressed and dried, and then the dried paper sheets are trimmed and cut to obtain paper for calligraphy and painting.

[0043] Specifically, after the slurry is evenly deposited on the base cloth, the rotation of the papermaking mesh is stopped, and the spraying is stopped. The wet paper sheet with the base cloth is removed from the papermaking mesh, and then the wet paper sheet with the base cloth is pressed to reduce the moisture content in the wet paper sheet. Then, the wet paper sheet with the base cloth after pressing is transferred to a drying device for drying. After all the moisture in the wet paper sheet with the base cloth is removed, a paper sheet combining the slurry and the base cloth is obtained. After the paper sheet is cut into the required size, paper for calligraphy and painting is obtained.

[0044] It should be noted that the drying equipment may be, for example, a drying cylinder, a hot air drying device, and the like.

[0045] Specifically, when drying wet paper sheets, it is necessary to first determine the type and thickness of the paper sheets, and adjust the parameters of the drying equipment according to the type and thickness of the paper sheets to ensure that the paper sheets can be dried evenly and avoid problems such as paper sheet deformation and wrinkling caused by uneven drying.

[0046] By adopting the above-mentioned production method, calligraphy and painting paper with a textile base fabric as the base is produced, so that the calligraphy and painting paper has a double-layer structure of woven and non-woven. The plain base fabric can provide additional support for the paper pages, enhance the toughness, stress and strength of the paper pages. The calligraphy and painting paper produced by the production method in this embodiment combines woven and non-woven technologies, can effectively reduce the looseness problem caused by fiber aging, and extend the storage time of the calligraphy and painting paper. Moreover, the calligraphy and painting paper has the special texture of the textile base fabric, which can bring new artistic expression to calligraphy and painting creation and improve the artistic effect.

[0047] For the comparison between the calligraphy and painting paper produced by the production method in this embodiment and the traditional calligraphy and painting paper, please refer to the data in the following table. In the process of testing and comparing the traditional calligraphy and painting paper with the calligraphy and painting paper produced by the production method in this embodiment, Anhui Xuan paper was selected for testing and comparison because it has a soft and tough texture, can withstand repeated folding and rubbing without being easily damaged, and is very representative among traditional calligraphy and painting papers.

[0048] Comparison table of traditional calligraphy and painting paper and calligraphy and painting paper produced by the production method in this embodiment

[0049]

[0050] In the above table, F represents the tearing strength, X represents the tearing index, and the tearing strength F represents the length of time required to tear a paper sheet under certain conditions. The tearing strength F reflects the tearing resistance of the paper sheet.

[0051] As shown in the above table, the tearing strength F of Anhui Xuan paper is 195.9N, which means that under the test conditions, the force required to tear 4 layers of Anhui Xuan paper is 195.9N; the tearing strength F of the calligraphy and painting paper produced by the production method in this embodiment is 1100.57N, which means that under the test conditions, the force required to tear 4 layers of calligraphy and painting paper produced by the production method in this embodiment is 1100.57N. It can be concluded that the strength of the calligraphy and painting paper produced by the production method in this embodiment is higher than that of Anhui Xuan paper.

[0052] The tear index X is the ratio of the tear strength F to the weight of the paper, and the unit is m 2 / g, the formula of tear index X is: X = F / gram weight, where F is the tear strength, gram weight is the weight per unit area of ​​the paper sheet, and the unit is g / m 2 The tear index X is used to compare the tear resistance of paper sheets with different gram weights. In the above table, the tear index X of Anhui Xuan paper is 13.060m 2 / g, and the tear index X of the calligraphy and painting paper produced by the production method in this embodiment is 22.928m 2 Although the calligraphy and painting paper produced by the production method of this embodiment has different gram weights and thicknesses from Anhui Xuan paper, the tear index X shows that the calligraphy and painting paper produced by the production method of this embodiment has higher tear resistance than Anhui Xuan paper.

[0053] Through testing and comparison, it is found that the wear resistance, tear resistance and tear index of the calligraphy and painting paper produced by the production method in this embodiment are higher than those of the traditional calligraphy and painting paper participating in the test. The calligraphy and painting paper produced by the production method in this embodiment solves the problem that traditional calligraphy and painting paper is prone to deformation, cracking and holes. At the same time, mineral gouache pigments can be altered and stacked on its surface, meeting the painting requirements of color ink painting, and the woven plain weave also gives the paper a unique artistic effect.

[0054] It should be noted that this embodiment discloses a method for producing paper for calligraphy and painting by combining woven and non-woven technologies using a spraying method. In other embodiments, the bamboo screen papermaking method can also be used, that is, a layer of the base cloth in this embodiment is stretched on the bamboo screen, and the thickness of the paper sheet is controlled by the number of water discharges. The pulp adheres to the base cloth under the action of its own gravity, and the mesh of the bamboo screen will filter out the moisture in the pulp, so that the fibers in the pulp and the base cloth are intertwined, thereby forming a paper sheet with a certain strength and thickness with a base cloth.

[0055] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
