Paper as an important material in the history of human civilization, after a long process of development and continuous improvement and innovation, it has become an indispensable item in our modern society.
The first stage: the early period of writing practical materials. The earliest practical material for writing appeared around 2600 BC. At that time, people used hard materials such as SLATE and wood as writing carriers, but this material was laborious and not durable, and was only suitable for important documentary records.
The second stage: the simple paper-making period. In 105 AD, the Han Dynasty produced paper in the official way, using grass and wood fibers, linen, rattan, etc., to make paper, because of the high cost, mainly for calligraphy, book reproduction and other important occasions.
The third stage: the overall promotion of paper technology period. In the Tang Dynasty, paper-making technology was greatly developed. The raw materials for paper production expanded from grass and wood fibers to taupe straw and waste paper, thereby reducing production costs. Since then, the technology of making paper has gradually spread to other countries and regions, such as Japan, South Korea, India and so on have begun to use paper.
The fourth stage: industrial production of paper period. In the 18th century, paper manufacturers began producing paper online and using steam power to drive giant paper machines. In the 19th century, wood became the main raw material for the manufacture of paper, and many different types of paper appeared.
The fifth stage: green sustainable development period. After entering the 21st century, the rise of the concept of green environmental protection and sustainable development has made the paper manufacturing industry begin to pay attention to environmental protection and energy saving and emission reduction. Paper manufacturers have adopted renewable raw materials, such as bamboo, wheat straw, straw, corn straw, etc., as well as green materials such as pure cotton and recycled paper, to achieve recycling, and continue to develop and apply new technologies to achieve energy saving and emission reduction, reduce the impact of enterprises on the environment, and promote environmental protection
As an important material in the history of human civilization, paper has gone through a long process of development, after continuous improvement and innovation, it has become an indispensable item in our modern society. With the rise of the concept of green environmental protection and sustainable development, the paper manufacturing industry is also upgrading and transforming, constantly seeking a more green and environmentally friendly development model, and has developed a variety of new green paper products. In the future, with the continuous development of science and technology, we can look forward to the birth of more new paper products with technical content and artistic value.
