Paper making is a old invent form China, here, I’d like to reveal the ancient paper making process. If you have interest, let’s look and see.

1.Cut bamboo and bleach in pond

There’s a specific word “kill the green” , cause bamboo is green, and our material is bamboo at first. Bamboo is one of the important sources of ancient papermaking. Therefore, the southern China region, which is rich in bamboo, is the main producing area of bamboo paper. The bamboo used for papermaking is preferably new-born bamboo with branches and leaves. Paper craftsmen usually go up the mountain and chop bamboos before and after the grain in ear. Each bamboo is cut into 5 to 7 feet long, and then a pond is excavated on the spot. The cut bamboo is soaked in the pond for 100 days, and when it is taken out, it is washed hard to make the green shell. And the bark is removed, the purpose is to soften the bamboo.

The material source of papermaking in the 19th century was changed from rags to wood, because wood is easy to obtain and the cost is low. However, because wood fibers are composed of lignin, lignin will be oxidized, which is the reason for the yellowing of paper. This problem is aggravated by the addition of acid in the papermaking process.

2.Boil

The second step of making bamboo paper in 《Techartgroup》 is to mix bamboo material into lime water and soak it in a wooden imperial barrel and cook for 8 days and nights. After cooking with lye, the raw materials are lignin, gum, resin, etc. The impurities are removed. Then take out the cooking raw materials and rinse them in the clear water pond, and then put them into the pot to soak the lime water for cooking, and repeat this for more than ten days. After repeated cooking and rinsing, the fiber of bamboo gradually decomposes.

3.Wash material into the curtain

The third step of ancient papermaking is to take out the boiled raw materials and place them in a stone mortar to pound them into a muddy surface. The smashed raw materials are mixed with an appropriate amount of water to completely separate the fibers and soak water to become a suspension of paper fibers. , And pour it into the paper slot. Then use a thin bamboo curtain to filter out the pulp, and the paper fibers are left on the bamboo curtain to form a paper film. A catalyst made of pure natural plant materials is used to control the concentration of the paper fiber suspension.

This process is the most laborious process in the papermaking process. The papermaking craftsman stands by the paper trough and repeats the actions of scooping water and lifting the bamboo curtain, each time bearing a weight of 20 kg. In addition, you have to rely on experience when collecting paper. Lightly copied paper will be too thin, and too heavy paper will be too thick. It depends entirely on the craftsman’s technique.

4.Cover curtain to press paper

Lay the bamboo curtain with the paper pulp upside down on the press board, and then carefully remove the bamboo curtain, the paper film will fall on the board. Slowly stack up layers of paper, and then squeeze it with a heavy object to discharge the moisture in the paper. The paper film is slowly formed under the squeeze of the heavy object, and becomes a square sheet of paper. Hand-made paper can only make 300 to 500 sheets of paper a day per craftsman.

5.Drying

The lane for drying paper is a brick wall made of two soil bricks. There are gaps between the bricks to allow hot air to leak out. When baking the paper, light a fire in the alley, and then spread sheets of wet paper on the wall. The heat emitted from the gap makes the paper dry slowly. After it has dried, it will be a piece of usable paper.
