Description

Method of surface treatment of Korean paper used for imitation of cultural properties

The present application relates to a method for surface treatment of Korean paper used for imitation of cultural heritage, and to a technique for providing an optimal process for surface treatment and a method for lining Korean paper.

Hanji is a paper unique to Korea that is manufactured using bast fibers such as mulberry, samji mulberry, anpi and hemp as raw materials. Since bast fibers have a fiber length (10 mm) that is much longer than that of softwoods (3 mm) or broad-leaved trees (1 mm) used as chemical pulp, the tissue itself has superior strength compared to wood pulp, and the fibers It has excellent strength and can make tough paper.

Korean paper has a softer feel than normal paper, flexible folding, toughness, and ink-resistance. It has the property that the characteristics of paper do not change even after passing. In particular, Hanji is known as a paper that can endure a thousand years, and in the case of Mugujeonggwang Daedarani Sutra, it is known that it was made in the 8th century.

Traditional hanji is a technology to make hanji in the old way, and the manufacturing method of traditional hanji is as follows.

First, raw materials for Korean paper such as mulberry, mulberry, and anpi are harvested in winter. Harvested hanji raw materials are processed through the process. The dakmuji process is a process of steaming harvested Korean paper raw materials using steam, in order to remove the bark containing bast fibers from the raw materials. Peel off the skin of the raw material after the dakmuji process. The peeled skin is called mill scale. After thoroughly washing the mill scale again with clear water, remove the black parts of the epidermis with a knife. The raw material of the skin from which black parts, dust and impurities have been removed is called white skin.

The white skin is boiled. The white skin can be boiled with various drugs. As a natural drug, meat material made by burning rice straw, buckwheat stalk, cotton stalk, soybean stalk, and red pepper stalk and making lye can be used. As a general chemical, caustic soda can be used. have. Boiling refers to the process of sufficiently boiling the white skin at about 100°C with meat ashes or caustic soda. White skin that is boiled using caustic soda, a general chemical, instead of natural meat, is cleaner and easier to process, but it cannot be considered as a raw material for traditional Korean paper.

After boiling, the raw material of Korean paper goes through a washing process to remove all soluble impurities contained in the raw material of Korean paper.

A bleaching process is performed on the raw material of Korean paper from which soluble impurities have been removed. The bleaching process includes solar bleaching using sunlight and chemical bleaching using sodium hypochlorite or chlorine dioxide. In the case of chemical bleaching, the molecular weight of cellulose in the raw material of Korean paper is significantly reduced, and thus the characteristics of Korean paper, which boasts long-term preservation, can be easily lost.

After the bleaching process, a teeing operation is performed to remove impurities that have not been sufficiently bleached to complete the processing of the raw material for Korean paper.

A beating process is performed on the raw material of Korean paper. The beating process is a process in which the raw material of Korean paper is beaten with a stick called a dangbang and continues to be crushed. Recently, a machine called a calbiter is used to shorten the length of the raw materials of Korean paper and to increase the uniformity.

After the beating process, the raw material of Korean paper is put into a paper container and the Korean paper is knitted with a foot made of bamboo flesh. At this time, the raw material of Korean paper is mixed with a natural additive called daffodil to make Korean paper. Duckweed is obtained in the form of a juice from the root of a plant called Hwangchokgyu, and when used together with the raw material of Korean paper, it improves the strength or uniformity of Korean paper. There are two methods of knitting Korean paper: single-foot knitting and twin-foot knitting, and it is generally known that single-foot knitting is the traditional Korean paper manufacturing method. The single knitting method can make Korean paper with better strength and uniformity than the double knitting method. PAM (polyacrylamide) or PEO (polyethyleneoxide) may be used instead of the daffodil. After draining the moisture of the Hanji made by single or double stitching, dry it on a hot iron plate or dry it on a wooden board in sunlight to complete the Korean paper.

In the case of manufacturing Korean paper using mulberry fibers, etc. using this traditional process, it is possible to manufacture Korean paper with excellent strength properties such as tensile strength, rupture strength, and tear resistance, and with excellent preservation properties that can be stored for more than 1000 years. have. Hanji has been widely used as window paper since ancient times because it has a strong affinity with natural phenomena such as light, wind, and moisture, which allows the wind to pass through and absorbs moisture well. Hanji is divided into uses according to its quality and title. It is used as a paper for shoji for doors, copy paper used as a seal of genealogy, Buddhist scriptures, and ancient books, hwaseon paper used for four gentlemen or flowers and birds, New Year's cards or wedding invitations, etc. It is used in a variety of ways, such as used Taiji (苔紙).

Hanji is also used to restore cultural properties. In particular, Korean paper is used to imitate Buddhist paintings, folk paintings, murals, and genre paintings. There was a problem in that the conventional Korean paper used as a copying paper was easily scratched or, conversely, the brush lines were easily spread.

According to an embodiment of the present application devised to solve the problems of the prior art, it is an object of the present invention to provide a method for surface treatment of Korean paper that can produce Korean paper that does not spread and does not split brush lines as a traditional Korean paper used for imitation of cultural heritage.

One aspect of the present application relates to a method for surface treatment of Korean paper.

Hereinafter, the surface treatment method of Korean paper will be described in detail for each step.

S10: Prepare a wooden plywood.

2 is a schematic diagram of a wood plywood according to an embodiment of the present application.

The length, width, thickness, etc. of the wood plywood are not particularly limited. In addition, the type of wood is also not particularly limited. The size of the wood plywood is preferably slightly larger than the size of Korean paper. Using wood plywood serves as a support with an even and flat surface, but since wood has many pores, air is circulated through the wood plywood so that the Korean paper and air placed on the wood plywood can circulate.

S20: Place the first Korean paper on the prepared wood plywood.

As shown in FIG. 3, the first Korean paper is placed on the wooden plywood.

Hanji is not particularly limited, but one battery (about 70x136cm) weighs 22 to 23 g of Korean paper can be used. The size of the Korean paper is also not particularly limited, and each size may be applied according to the user's intention.

S30: Apply water on the first Korean paper.

Water is applied or sprayed on the first Korean paper positioned on the wood plywood. The apparatus or method for applying water is not limited, and water is applied sufficiently so that the water-soaked Korean paper adheres to the wood plywood. In order to ensure complete adhesion, it is desirable to use a brush to send air bubbles that may occur between the Korean paper and the wood plywood toward the edge of the Korean paper as much as possible to remove them.

S40: To cover the edge of the first Korean paper and a part of the wood plywood, the second Korean paper (paper paper) coated with the first paste is overlapped on one side, and the first Korean paper is closely attached to the wood plywood.

As shown in FIG. 3, the second Korean paper (paper sheet) is cut to form a padding part to cover the edge of the first Korean paper and a part of the wood plywood in a state in which the first Korean paper holds water and is in close contact with the wood plywood. place it For example, when the shape of the first Korean paper is rectangular, the second Korean paper (paper sheet) is positioned on each of the four edges.

Apply glue to one side of the second Korean paper so that it can be adhered to the first Korean paper and wooden plywood. Here, the pool is the first pool, and the first pool is the new pool. Sinful refers to a paste made by boiling wheat flour in water, that is, a grass that is not a grass that has been repeatedly immersed in water.

S50: Dry the first Korean paper adhered to the wood plywood.

The drying method and time are not particularly limited, but may vary depending on weather, temperature, humidity and season. For example, it can be dried in a cool shade, and can be dried for 12 to 36 hours.

S60: Coat the dried first Korean paper.

Dochim is a flattening operation of Korean paper, and can increase smoothness. You can use the necessary tools for flattening the Korean paper. For example, dochim is a process in which the paper surface is made dense, smoothness is improved, and the pasted paper is evenly hit with a treadmill-shaped dome machine to give it gloss.

S70: One side of the first Korean paper, the first glue: the second glue is 1: 1.5 to 2.5, and the third paste coated with the third paste is overlapped, and the first Korean paper and the third Korean paper are in close contact with each other and docked. to form

As shown in FIG. 4 , the third Korean paper is docked on the dried first Korean paper. In this way, it is possible to manufacture the Korean paper for lining.

Here, the glue is applied to one side of the third Korean paper, that is, the side in contact with the first Korean paper. Here the pool is called the third pool. The third pool is a mixture of the first pool and the second pool, and the second pool is preferably a high pool.

Coriander is a wheat starch paste from which proteins have been removed, and is used for the purpose of preventing fungi and pests on Korean paper. In addition, the advantage of the paste is that it has a low viscosity and has excellent flexibility and elasticity, so it is used for folding scrolls.

In the present application, the new grass is mixed with the high grass in a ratio of 1: 1.5 to 2.5 and used.

In the present application, a method for manufacturing gourd is characterized. In general, in order to prepare gourd, it is soaked in wheat flour and left for a certain period of time to prepare fermented grass and use it as a gourd. In contrast, in the present application, the process of putting wheat flour in a container together with water, removing the liquid solution located in the upper layer, and refilling it with water is repeated every day.

Specifically, after putting wheat flour into a container, adding water, and removing the liquid component from the upper layer once a day, add water again for 6 months or more. It is manufactured by repeating water immersion for 10 years.

Compared to the conventional common gourd, the old grass produced through this process is excellent in preventing pests and diseases, and it has excellent flexibility and elasticity when serving, and it can be made according to the purpose because it is submerged by year.

In particular, nutrient content, viscosity, and acidity can be adjusted, and because it is managed only by immersion without boiling, spoilage can be prevented, and it is easy to manage during the fermenting process, and mass production and production by use are possible.

S80: Dry the lining Korean paper.

The drying method and time are not particularly limited, but may vary depending on weather, temperature, humidity and season. For example, it can be dried in a cool shade, and can be dried for 12 to 36 hours.

S90: Coat the dried backing paper.

Dochim is a flattening operation of Korean paper, and can increase smoothness. You can use the necessary tools for flattening the Korean paper. For example, dochim is a process in which the paper surface is made dense, smoothness is improved, and the pasted paper is evenly struck with a treadmill-shaped dojim to make it shiny.

S100: Apply the fourth glue on the third Korean paper for the backing Korean paper.

The 4th pool is a thin grass made by boiling the 2nd pool preferably from 6 months to less than 2 years and mixing it with water in a ratio of 5cc to 20cc: 1000cc.

S110: Dry the 4th glue-coated backing Korean paper.

The drying method and time are not particularly limited, but may vary depending on weather, temperature, humidity and season. For example, it can be dried in a cool shade, and can be dried for 12 to 36 hours.

S120: A first glue application step of applying 3 to 6% by weight of glue heated in a bath on the third Korean paper to which the fourth paste is applied.

Glue is a viscous substance obtained by boiling animal hides, tendons, bone marrow, etc. and extracting only gelatin-based ingredients, and is mainly used for adhesives. For example, 4 g of this glue is mixed with 100 g of water, and then a liquid glue solution mixture is prepared by boiling it.

Glue is applied to one side of the Korean paper and serves to coat the Korean paper. Through this, it is possible to prevent the brush line from spreading.

S130: Dry the glue-coated backing Korean paper.

The drying method and time are not particularly limited, but may vary depending on weather, temperature, humidity and season. For example, it can be dried in a cool shade, and can be dried for 12 to 36 hours.

S140: Apply liquid alum on the third Korean paper coated with glue.

Alum is called alum, and is a generic term for double salts with sulfates such as aluminum sulfate, alkali metals, and ammonium.

Liquid alum is prepared by mixing 1 to 10 g of alum with respect to 1000 g of water, and then it is applied on the third Korean paper.

S150: Dry the alum-coated Chinese paper.

The drying method and time are not particularly limited, but may vary depending on weather, temperature, humidity and season. For example, it can be dried in a cool shade, and can be dried for 12 to 36 hours.

After that, you can add a fill-in test. When the ink line spreads on the surface with a brush by performing a brush line test on one side of the dried backing Korean paper and making a line with ink on one side of the dried backing Korean paper, a weight higher than the weight% of the glue used in the first glue application step % may further include a second glue step of re-applying the glue having a lower weight % than the weight % of the glue used in the first glue application step when grinding occurs.

This process may be repeated once or repeated two or more times.

S160: Coat the dried backing Korean paper.

Dochim is a flattening operation of Korean paper, and can increase smoothness. You can use the necessary tools for flattening the Korean paper. For example, dochim is a process in which the paper surface is made dense, smoothness is improved, and the pasted paper is evenly hit with a treadmill-shaped dome machine to give it gloss.

S170: Remove the backing Korean paper from the wood plywood.

Finally, when the desired surface treatment is completed, the Korean paper can be removed and used.

Another embodiment of the present application is Korean paper used for imitation of cultural properties as Korean paper surface-treated by the above-described surface treatment method.

In the case of using copying as a method of preserving Buddhist paintings, folk paintings, murals, folk paintings, etc. among cultural assets, if the Korean paper of the present application is used for copying, it is possible to manufacture the best copying Korean paper for cultural properties because no writing or writing occurs. have.
