Papermaking is one of China's four great inventions of human civilization in the history of a remarkable invention. China is the world's first silkworm silk weaving countries. For more than the ancients such as cocoon snag silk fabric, the remaining evil cocoon, cocoon and other diseases is to use floating floc Preparation of silk floss. Drift Xu completed, strips gallery will be some residue left over from cotton wadding. When the number of floating floc more, bamboo gallery residual floc accumulates into a thin layer of fibers, after drying, after stripping down, can be used for writing. The by-product of this floating floc small number, in the ancient books on the call He Di, or side with cotton wadding. This shows that the origin of China's papermaking has a history and relationship with the silk with cotton wadding. Eastern Han Yuan Xing Cai Lun improved the first year of papermaking. He used bark, hemp and head and worn cloth, fishing nets and other plant material, after-down pound, copied, baking paper and other manufacturing processes, the origin of modern paper. Since the invention of papermaking, the paper will be a new attitude into the social and cultural lives, and gradually spread in the land of China and later spread around the world. Paper is used to writing, printing, painting or packing of the sheet fiber products. Generally processed through the plant fiber pulping water suspension, a combination of on-line interlaced, the initial dehydration, and then by compression, drying made. China is the world's first invention of paper country. According to archaeological discoveries, the Western Han period (206 BC to AD 8 years), China has adopted a linen fiber paper. Rough texture, and a small number of high cost, not universal. Since ancient times, Chinese people already know how to raise silkworms, reeling.

This technology was later developed into a paper-making in the beating. In addition, the ancient Chinese used lime or plant ash water Sima degumming, this technology also for paper-making plant fiber degumming with inspiration. The paper is to make use of these technologies to develop. 造纸是中国的四大人类文明的伟大发明之一，在一个了不起的发明历史。中国是世界上第一个桑蚕丝绸织造的国家。使用的是浮动的绵絮体的制备等多个粗加工茧丝绸面料，剩下的恶茧，蚕茧和其他疾病的古人。漂移徐完成后，带画廊会有一些残留下来的棉絮了。当浮动絮状数目，竹廊剩余积累成絮状纤维薄层干燥后，经过剥离下来，可用于书写。补本浮动絮状少数产品在古籍，在电话赫底，或絮一边。这表明，中国的造纸历史的起源有一个与絮丝的关系。东汉袁悉嗯蔡鲁嗯改进了造纸的第一年。他用树皮，麻头和旧布，渔网和其他植物材料，在下拉磅，复制，烘焙纸和其他的制造工艺，现代纸的起源。自从发明造纸，该文件将是一个为社会和文化生活的新态度，逐步蔓延，中国的土地，后来在世界各地蔓延。 纸是用来书写，印刷，绘画或纤维板材产品的包装。一般来说，通过处理水悬浮植物纤维制浆，一上线隔行扫描，初步脱水，然后通过压缩，干燥了组合。中国是世界上首次发明纸的国家。据，西汉时期（公元前206年至公元8年）的考古发现，中国采取了亚麻纤维纸。粗糙纹理，以及成本高，而不是普遍少数。自古以来，中华民族已经知道如何养蚕，缫丝。秦，汉时劣势种族，绵茧工艺很受欢迎。这种处理方法与分，茧被称为漂移絮凝方法，运作的基本要素，包括多次殴打，以打破蚕衣服。这项技术后来发展成为一纸制作的殴打。此外，古人用石灰或草木灰水司马脱胶，这项技术也为造纸植物纤维脱胶与灵感。该文件是利用这些技术来发展。
