Description

Technical Field

[0001] The present invention belongs to the technical field of calligraphy and painting restoration, and particularly relates to a spraying and dyeing process in calligraphy and painting restoration. Background Art

[0002] Calligraphy and painting is an art form created by writing and painting on paper or silk using pigments and ink, and has extremely high ornamental and collection values. However, calligraphy and painting works are fragile and easily damaged. For the purpose of collection and exhibition, framer uses materials such as paper, silk, and damask silk to mount calligraphy and painting, which can protect and beautify them. Over time, calligraphy and painting mounts are gradually aged and damaged due to various factors, resulting in diseases. At this time, it is necessary to repair and remount the damaged ancient calligraphy and painting. Therefore, the dyeing process has become an important and indispensable process in calligraphy and painting mounting and restoration.

[0003] The most common traditional dyeing methods are brush dyeing (direct dyeing), dragging dyeing (pulling dyeing), and dipping dyeing. Brush dyeing refers to the method of evenly brushing the prepared colorant solution on the material to be dyed. This method is simple and easy to operate, and the color is uniform after drying and does not fade when exposed to water. It can be used for dyeing paper and silk damask, and is the most commonly used dyeing method. Dragging dyeing is to pour the prepared colorant solution into a square basin, attach one end of the short side of the material to be dyed to a wooden rod, slightly lift one end of the bamboo rod, and slowly drag the rest through the colorant solution, then let it hang naturally to dry after being evenly soaked in the colorant solution. This method is easily affected by the area of the colorant basin and is mostly used for dyeing small-sized paper. Dipping dyeing refers to the method of soaking the material to be dyed in the colorant solution for several days and then taking it out. This method requires long-term soaking and is only applicable to dyeing silk damask. The above three methods can specifically solve the dyeing problems of calligraphy and painting materials, with simple operations and excellent dyeing effects. However, in order to make the dyeing uniform and not run color, alum solution is added to the colorant solution, and it is generally recognized that alum solution accelerates the deterioration of calligraphy and painting.

[0004] Dry paper and silk damask are extremely prone to capillary action when wet. Without using alum solution, the colorant solution will spread unevenly the moment it contacts the dyeing object, and as the colorant solution moves, uneven colorant solution patterns will appear on the dyeing object, and the color distribution will be uneven after drying. On the other hand, the colorant solution without alum solution is easily dissolved in water, and the dried paper or silk damask will fade when wet during subsequent small or large backing operations. Therefore, how to achieve the purpose of uniform dyeing and non-fading without using alum solution is the current technical difficulty. Summary of the Invention

[0005] The purpose of the present invention is to provide a spraying and dyeing process in calligraphy and painting restoration that can achieve the effects of uniform dyeing and non-fading without adding alum solution to the colorant solution.

[0006] For the above purposes, the spraying and dyeing process in calligraphy and painting restoration provided by the present invention consists of the following steps:

[0007] Step 1: Lay the material to be dyed flat on the operating table, continuously atomize and moisten it, then sweep it flat until it is completely soaked, and then suck out the excess water. When the moisture content of the material to be dyed is 60% - 80%, evenly compact it.

[0008] Step 2: Stir the prepared colorant liquid without glue and alum water evenly, then sieve it and test the color. After the color is accurate, put it into a spray bottle for standby.

[0009] Step 3: Evenly spray the colorant liquid in Step 2 on the material to be dyed that has been compacted in Step 1. After it dries naturally, compare the colors. Repeat the spraying and dyeing according to the specific situation until the chromaticity value reaches the target requirement.

[0010] Step 4: Carry out low-temperature color fixation on the material dyed in Step 3.

[0011] Further, in the above Step 1, the material to be dyed is any one of paper and silk.

[0012] Further, in the above Step 4, the temperature for low-temperature color fixation is 40°C - 45°C, and the time is 5 - 15 minutes.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The spraying and dyeing process of the present invention adopts a method that combines the uniform wetting of the material to be dyed, the uniform spraying of the colorant solution, and low-temperature color fixation. First, the material to be dyed is evenly wetted with water, and the excess water is absorbed. After filtering the prepared colorant solution without glue and alum water, it is poured into a spray bottle and evenly sprayed on the evenly wetted material. After natural drying, the color is compared, and the spraying and dyeing are repeated until the chromaticity value reaches the target requirement. Then, the dried dyed object is subjected to low-temperature color fixation. Among them, before spraying and dyeing, the uniform wetting method must be used first to ensure the uniformity of water in the material to be dyed, reduce capillary action, and prevent the diffusion of the colorant solution; the colorant solution used in spraying and dyeing does not use glue and alum water, avoiding the damage of glue and alum water to calligraphy and paintings, and effectively protecting calligraphy and paintings; the colorant solution is evenly sprayed into the air with a spray bottle during spraying and dyeing, avoiding direct contact between the dyeing tool and the material to be dyed, and ensuring uniform dyeing; after spraying and dyeing, low-temperature color fixation is used to strengthen the color and eliminate the residual stress of the material at the same time, avoiding local deformation problems after mounting; after spraying and dyeing, the damaged parts are mended and supported, which can achieve the same effect as full-coloring with glue and alum water, simplify the full-coloring process, and improve the restoration efficiency. Through process practice verification, this process not only achieves the effects of uniform dyeing and non-fading, but also avoids the deterioration problems caused by the use of glue and alum water to the paper, greatly extending the lifespan of cultural relics. Moreover, the colorant is evenly sprayed with a spray bottle, avoiding the colorant accumulation or uneven texture caused by direct contact methods such as brush dyeing and dragging dyeing. After spraying the colorant, combined with the low-temperature color fixation process, the adhesion of the colorant is enhanced, the residual stress of the material is eliminated, and deformation after mounting is prevented. It provides a safer and more efficient technology for solving the dyeing problem in calligraphy and painting restoration, and provides evidence for realizing the non-glue and alum water mounting technology for calligraphy and painting cultural relics.

[0015] 2. The spraying and dyeing process of the present invention has significant application value and broad market prospects. This process effectively avoids the chemical damage to calligraphy and painting materials by traditional methods through non-glue and alum water dyeing, promotes the development of green and sustainable restoration technologies, and meets the needs of modern cultural relic protection. At the same time, its application scope is wide, and it can be applied to various materials such as paper, silk, etc., without being restricted by the size, and the operation is flexible and controllable. Through multiple spraying and dyeing, the tone of the original work can be accurately matched to ensure that the restoration effect is natural and realistic. The demand for non-glue and alum water dyeing and restoration process technologies in the cultural heritage restoration field (such as museums, archives, ancient book restoration institutions, etc.) is urgent, and the market potential is huge.

[0022] Embodiment 1

[0023] Step 1: Lay the paper to be dyed flat on the operating table, continuously atomize and moisten it, and then sweep it flat until it is completely soaked, and then suck out the excess water so that the moisture content of the paper to be dyed is 70% and it is evenly compacted.

[0024] Step 2: Stir the prepared colorant liquid without sizing alum water (prepared from Chinese painting pigments and water) evenly, then sieve and test the color. After the color is accurate, put it into a spray bottle for standby.

[0025] Step 3: Evenly spray the colorant liquid in Step 2 on the paper to be dyed that has been compacted in Step 1. After it dries naturally, compare the colors. Repeat the spray dyeing according to the specific situation until the chromaticity value reaches the target requirement.

[0026] Step 4: Fix the color of the paper dyed in Step 3 at 40°C for 10 minutes.

[0027] Comparative Example 1

[0028] Step 1: Take gelatin, alum, and water and mix them in a mass ratio of 3:1:200, then place them on a heating instrument to heat and dissolve to obtain sizing alum water.

[0029] Step 2: Mix the prepared colorant liquid and sizing alum water in a volume ratio of 100:9, stir evenly, then sieve and test the color. After the color is accurate, pour it into a basin for standby.

[0030] Step 3: Immerse a wool brush in the colorant liquid with sizing alum water added in Step 2, and stir to make the wool brush absorb the full amount of colorant liquid.

[0031] Step 4: Lay the paper to be dyed on the operating table, wet it and sweep it flat, and evenly brush the paper to be dyed with the wool brush full of colorant liquid in Step 3 until it is completely covered with the colorant liquid, and the brushing dyeing is completed.

[0032] Comparative Example 2

[0033] Step 1: Stir the prepared colorant liquid without sizing alum water evenly, then sieve and test the color. After the color is accurate, put it into a spray bottle for standby.

[0034] Step 2: Lay the paper to be dyed flat on the operating table, evenly spray the colorant liquid in Step 1 on the paper to be dyed, compare the colors after it dries naturally, and repeat the spraying according to the specific situation until the chromaticity value reaches the target requirement, and then let it dry naturally.

[0035] Comparative Example 3

[0036] Step 1: Stir the prepared colorant liquid without glue and alum water evenly, then sieve and test the color. After the color is accurate, put it into a spray bottle for standby.

[0037] Step 2: Lay the paper to be dyed flat on the operating table, evenly spray the colorant liquid in Step 1 on the paper to be dyed, compare the colors after it dries naturally, and repeat the spraying according to the specific situation until the chromaticity value reaches the target requirement.

[0038] Step 3: Fix the color of the paper dyed in Step 2 at 40°C for 10 minutes.

[0039] Comparative Example 4

[0040] Step 1: Lay the paper to be dyed flat on the operating table, continuously atomize and moisten it and then sweep it flat until it is completely soaked, then suck out the excess water, and evenly compact it when the moisture content of the paper to be dyed is 70%.

[0041] Step 2: Stir the prepared colorant liquid without glue and alum water evenly, then sieve and test the color. After the color is accurate, put it into a spray bottle for standby;

[0042] Step 3: Evenly spray the colorant liquid in Step 2 on the paper to be dyed compacted in Step 1, compare the colors after it dries naturally, and repeat the spraying according to the specific situation until the chromaticity value reaches the target requirement, and then let it dry naturally.

[0043] Observe the dyeing effects of the papers after spraying in the above-mentioned Example 1 and Comparative Examples 1-4. The results are shown in Figures 1 to 5 . From Figure 1 It can be seen that in Example 1, after the paper to be dyed is evenly sprayed with water and wetted and then sprayed with the colorant liquid without glue and alum water, the dyed paper has uniform dyeing, and after low-temperature color fixation, the paper is flat and does not wrinkle. As Figure 2 shown, although the paper dyed by the traditional glue and alum dyeing method in Comparative Example 1 has uniform dyeing, the paper is extremely easy to wrinkle and is not flat, increasing the difficulty of the subsequent repair process. Figure 4 Figure is the dyeing effect after directly spraying the colorant liquid without glue and alum water and low-temperature color fixation without wetting in Comparative Example 3. Although the paper is flat and does not wrinkle after dyeing, due to uneven wetting of the paper, white spots appear in the places with more moisture, and the pigment cannot infiltrate, resulting in local pigment loss, leading to extremely uneven dyeing, indicating the necessity of atomizing and wetting before dyeing. Figure 5It is the dyeing effect of the paper in Comparative Example 4 after being wetted and spray-dyed without low-temperature fixation. Although the paper is evenly dyed, it wrinkles significantly after natural drying, indicating the necessity of low-temperature fixation. The dyed paper in Comparative Example 2 without sufficient wetting and without low-temperature fixation is as Figure 3 shown. There is a local lack of pigment on the paper and the paper wrinkles significantly, indicating the importance of atomizing and wetting before dyeing and low-temperature fixation. The above experimental results show that it is essential to perform atomizing and wetting before dyeing and low-temperature fixation after dyeing using a sizing solution without alum.
