Paper is one of the four great inventions in ancient China. As early as 105 AD, Cai Lun summed up the experience of using hemp paper machine toilet tissue machine fiber paper since the Western Han Dynasty, improved papermaking, and used bark, hemp, rags, and old fishing nets as raw materials for papermaking. After papermaking came to Europe. By the beginning of the 18th century, a Dutch-style beater appeared, which changed the process of pounding into pulp. This was an important step in the mechanization of the papermaking process. In 1798, the Frenchman Robert obtained a patent for a handless endless paper machine and later passed the British Funded by Neil Brothers of Renford County, British technician Tang Jin was improved into a long-web paper machine that can continuously form paper in 1803, and successfully produced paper in 1805; in 1809, British Dickinson trial-produced a successful round-web paper machine.
In terms of preparation of pulp, in 1839, Pitt of Germany began to use a cooking pot to cook old cotton cloth to make pulp; in 1843, Kerr of Germany invented the milling method of peeling wood fiber and made pulp, which was improved by Voltel for ten years. Achieved success; in 1851, Burgess in England and Watt in the United States invented caustic soda wood pulping; in 1857, Tillman in the United States invented sulfite wood pulping technology; in 1884, German chemist Dahl invented sulfate wood pulping technology. These inventions opened the way to use wood as the main raw material for papermaking. By the early 20th century, papermaking machinery had become large-scale and high-yield industrial machinery.
