The principle of papermaking:
Pulping is to dissociate plant fiber raw materials into natural pulp or bleached pulp by mechanical method, chemical method or a combination of the two. Papermaking is to combine pulp fibers suspended in water into sheets that meet various requirements through various processes.
Another important factor in papermaking is beating and beating of fibers. By using a stirring knife and high-power machinery, plant fibers are bifurcated and broken, and then paper is made with great binding force, unlike smooth silky fibers that easily slip off. In addition, the crumbs and paste produced after pulping have the functions of filling pores and bonding paper in the paper-making process.
