The manufacturing process of traditional papermaking is

Until the Eastern Han Dynasty and the period of Emperor Wudi of the Han Dynasty, after Cai Lun's improvement, a set of relatively stereotyped papermaking technology was formed, which can be roughly summarized into four steps: the first step is the separation of raw materials, that is, the raw materials are degummed in alkaline solution by soaking or cooking and dispersed into fibers; The second is beating, that is, cutting off fibers by cutting and ramming, and sweeping them into pulp; The third is papermaking, that is, the pulp is made into slurry through water seepage, and then the pulp is picked up by a fishing machine (pad) to interweave the pulp into thin wet paper on the fishing machine; The fourth is drying, that is, drying or drying wet paper, and taking it off becomes paper. Chop bamboo and float it in the pond: chop bamboo and soak it in the pond to make the fiber fully absorb water. You can also add plant raw materials such as bark, hemp head and old fishing net and mash them. Boil until it is yellow enough: cook the broken materials until the fibers are dispersed and until they are cooked into slurry. As you can see in the picture, the broken materials in the cauldron are pressed with big stones, which helps to boil completely. Throw the material into the curtain: after the pulp is cooled, pick up the pulp with a flat bamboo curtain and filter the water to become a paper film. This step requires skilled skills to fish out the paper film with moderate thickness and uniform distribution. Cover the curtain and press the paper: fold the paper film out one by one, press it with a wooden board, put heavy stones on it and press the water out. Through-fire baking: stick the semi-dry paper film on the fire to dry, and take it off to get the finished product.
