What is the process of papermaking?

The first is the separation of raw materials, that is, degumming raw materials in alkaline solution and dispersing them into fibers by retting or cooking.

The second is beating, that is, cutting the fiber and sweeping the fiber into pulp.

The third is papermaking, that is, the pulp is made into slurry through water seepage, and then the pulp is fished out with a fishing machine (mat), and the pulp is interwoven 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.

Papermaking is one of the four great inventions in ancient China. Compared with other writing materials, the paper surface is smooth, white and inky, and can also be dyed; Wide format, many characters, easy to cut and make into various types. These incomparable advantages make paper, once invented, enduring, spread all over the world and deeply loved by the world.

Key points of papermaking technology:

Few technological innovations can last as long as papermaking. Wherever paper appears, it will immediately destroy more primitive writing surfaces, such as stones, wood blocks, mud flakes, paraffin wax and laminated bark paper or papyrus mats.

The wonder of paper lies in cellulose, which is a gift from chemistry. It is a very thin material, which is easy to make. Its characteristics are softness, tensile strength, thinness and easy to make. A piece of paper is the regeneration of recombinant plants, for human use only.

The main raw materials of hand-made paper are hemp, bark, bamboo and rice chips. Hemp includes hemp, ramie, flax, green hemp and jute. Bark includes Pteroceltis tatarinowii, Cortex Mori and Broussonetia papyrifera. There are many kinds of bamboos, among which Phyllostachys pubescens and Dendrocalamus affinis are the most widely used.
