The originator of papermaking - Cai Lun

Cai Lun, Zi Jingzhong, Guiyang (now Xiangyang County, Hunan Province), and the Eastern Han Dynasty Emperor Ming Yongping (75 AD or earlier) began to perform in the Imperial Palace in the capital. During the early years of Zhang Dijian (76-84 AD), he served as a small yellow door (a relatively low position in the eunuchs). He emperor was emperor (AD 89) and was promoted to serve as a waitress and emperor to participate in state secret affairs. Later, he served as an official ambassador and was in charge of the imperial court workshop.

Cai Lun summed up the experience of using hemp fiber papermaking since the Western Han Dynasty (the Western Han Dynasty Wudi period), improved papermaking, made use of raw materials such as bark, rags, ramie, and old fish nets to produce high-quality paper through careful craftsmanship. In the first year of Yuanxing (AD 105), it was reported to the court and praised by Han and Emperors. Since then, the papermaking technique has been promoted. Therefore, he was later called "Longting" (the land was sealed in Yangxian County, Shaanxi Province today), so the paper he organized and produced was called "Chen Houzhi." Because Cai Lun's contribution to papermaking made China's Eastern Han Dynasty at the beginning of the second century AD, it had completed a significant papermaking technology reform.

First, a variety of plant materials were used to solve the problem of insufficient raw material resources for papermaking. The use of waste materials such as rags (a linen in that time), hemp heads, and broken fish nets increased raw material sources and reduced the cost of paper. In particular, the use of bark as a raw material is a major creation. It can be said that it created a precursor to modern wood pulp and opened up a broad path for the development of the paper industry.

Second, there is a big progress in craftsmanship. The use of a variety of raw materials puts new demands on the process and promotes the reform of papermaking technology. Due to the lack of specific records in the history books, it is difficult to understand in detail the actual operation at that time. Today, handmade papermaking has basically been replaced by machine papermaking, but there are no fundamental changes in the principles of papermaking and basic production processes.

Third, papermaking has since become an independent industry. In the past, paper was only a by-product of the textile industry, and its output was very low. Technological improvements were also very limited. The opening up of new raw materials and the adoption of new technologies have made papermaking independent from the textile industry. This is a significant turning point in the history of papermaking. Since then, the production of paper has developed rapidly.

Since the 2nd century AD, Cai Lun has improved his papermaking technology and produced excellent paper, which has been welcomed and loved by people. Papermaking has rapidly spread to all parts of the country, and Jianfan and Qiang have gradually been eliminated by history. From the third to the fourth century, paper became the only writing material in our country. At the same time, papermaking technology has been continuously improved and is increasingly perfected.

Later, the papermaking technology invented in our country spread all over the five continents, which greatly promoted the spread and exchange of world scientific culture and profoundly influenced the course of world history. Just as British scientist Francis Bacon said in his evaluation of China's “four great inventions” including papermaking, “They have changed the entire face and state of things in the world, and have produced countless changes; see There is no empire, no religion, no prominent figure, and the human cause has exerted greater power and influence than the discovery of these machines.
