Ancient papermaking process

Ancient papermaking process is as follows:

1, chopping bamboo floating pond: papermaking craftsmen go up to the mountains to cut bamboo, bamboo soak in the pond, will cut off the bamboo in the pond on the immersion of 100 days, out of the hard pounding to make the green shells and bark off, in order to let the bamboo material soften.

2, cooking and foot fire: the softened bamboo material mixed with lime water immersed in a wooden barrel steaming for 8 days, so that the raw materials in the lignin, resin, gum, resin and other impurities in addition to the removal. Then take out the steaming raw materials into the pond rinsing, and then put into the pot soaked in lime water steaming, so after repeated for ten days. After repeated steaming, rinsing, bamboo fiber is gradually decomposed.

3, the soup into the curtain: take out the boiled raw materials in the stone mortar hard pounded into mud, pounded raw materials with the right amount of water, become a suspension of paper fibers, and then poured into the paper inside the tank. Then filtered in the pulp with a fine bamboo curtain, the paper fibers remain on the bamboo curtain to form a layer of Jing paper film.

4, over the curtain pressure paper: the pulp of the bamboo curtain inverted on the board, and then remove the bamboo curtain, the layer of Jing paper film will fall on the board. Slowly stacked up layers of paper, and then squeezed with a heavy object, discharging the water in the Jing paper. Under the weight of the extrusion of the paper film is also slowly molded into a four-square sheet of paper, so that the paper is basically caused.

5, through the fire baking: baking paper in the alley is two brick wall made of earth bricks, baking paper first in the alley fire, and then to light fine copper tweezers will be a sheet of wet paper spread on the wall, from the gap in the heat emitted from the paper slowly dry, dry after uncovering is a usable piece of paper.
