From the above, we can also see that paper was invented as early as the Western Han Dynasty, but the quality of the paper at that time was poor; it could not be used for writing, and the quality of the paper was only improved in the late Western Han Dynasty. On the basis of this papermaking Macor Ceramics technique, Cai Lun improved the raw materials and processes, and produced high-quality paper. In particular, Cai Lun expanded the raw materials for papermaking, and provided a variety of plant fibers for papermaking in the future. condition. Paper is widely spread and widely used by people. The papermaking technology has been further improved, and the papermaking area has gradually spread from the Luoyang area of Henan to Yue, Shu, Shao, Yang and Anhui, Jiangxi and other places before the Jin Dynasty. The output and quality are increasing day by day. The raw materials for papermaking are also diversified, and there are many types of paper. Such as bamboo curtain paper, there are obvious lines on the paper surface, and the paper is tight, thin and evenly thin. Yanxi has rattan paper made of rattan skin, which is even and smooth, white as jade, and does not leave ink. Dongyang has fish roe paper, also known as fish paper, which is soft and smooth. Jiangnan made paper with straw and wheat straw fibers, which was yellow in color, rough in Macor Ceramics texture and difficult to write. In the north, mulberry bark fiber is used to make paper. It has excellent texture, white color, light and soft, strong tensile force, and the paper is torn like cotton, so it is called cotton paper. Cai Lun made a wide range of raw materials for papermaking. The paper made from rotten fishing nets was called net paper, and the paper made from rags was called cloth paper. Because the rags of fishing nets were classified as hemp fibers at that time, they were collectively called hemp paper.
In order to prolong the life of paper, a new technology of dyeing paper has been invented in Jin Dynasty, that is, the juice is extracted from yellow tillers, and the paper is soaked and dyed. The impregnated paper is called dyed paper, which is natural yellow, so it is also called jute paper. Yellow paper has the function of killing insects and moths. By the Jin Dynasty (4th century), paper had finally replaced silk slips as the main Macor Ceramics writing material. Cai Lun played a great role in promoting the production of hemp paper and vellum paper. Although he was not the inventor of papermaking, his historical status as a technological innovator and organizational promoter should be affirmed.
