  • Mô tả: This chapter presents the history of papermaking followed by an overview of chemical pulping and papermaking processes. It describes the important milestones in the papermaking industry, such as, invention of paper and development of papermaking machine. Regardless of the method of making paper, whether by machine or by hand, there are some common steps to papermaking. The raw material is pulped to allow separation of the individual vegetable fibers. The pulp is then washed to remove pulping chemicals. The pulp may then be bleached if it is to be used in white papers. The pulp is treated with beating or refining to separate the fibers from each other and to roughen the surface of the fiber. Most papers do not use adhesives, but rely on hydrogen bonding between fibers. Paper is then formed by running a dilute slurry of pulp through a screen, and then most of the water is allowed to drain out by gravity. Additional water is then pressed from the sheet. The last water is removed by evaporation. Paper production in developed countries seems to be limited by fiber supply. The chapter suggests various references, abstract indices, technical and trade journals for further studies on papermaking technologies.
