Answer:
To make paper from trees, the raw wood has to be turned into pulp. This pulp is made up of wood fibers and chemicals that are mixed together. They can either be processed mechanically or chemically. With mechanical pulping, machines grind wood chips into pulp. The fibers are ground down more in this process, so the paper that is made is not as strong. This kind of paper is commonly used for newsprint and phone books.
The second, and more commonly used, method is chemical pulping. Chemical pulping creates stronger paper, since this method eliminates most of the natural glue-like substance in the pulp.
Pulp has a lot of liquid in it that must be removed in order to make the paper. The process is not much different from the process used by the ancient Chinese nearly 2,000 years ago. The pulp is sprayed onto large mesh screens. This creates a mat of pulp that then goes through several processes to have the water removed and is dried out to become paper. The wet paper is lifted from the mesh screen and then squeezed many different times through a series of presses to squeeze the water out. Once the paper has about 50 percent of its water removed, it is heated to dry to between 5 and 8 percent water content. At this point, the paper may go through treatments to create different textures. It is then wound into a reel. These reels of paper are so large that large cranes have to be used to move them.
