The paper is then shredded, mixed with water and chemicals, and pulped to form a mixture of water and cellulose fibers. A variety of additive materials are introduced to the papermaking pulps during the initial pulping process. Some additives are sizing (this imparts a degree of water resistance), wet strength agents (for hand towels), and defoamers (to counteract the foaming in pulpers caused by coated papers) are typically introduced. The chemical aspects of paper fibers are all-important in determining the sheet properties, such as absorbency, strength, brightness, and printability. The tendency of cellulose fibers to bond together, when dried from a water suspension is basic to papermaking technology.The continuous paper machine (generally a Fourdrinier machine or a cylinder machine) converts a very dilute suspension of paper fibers and other ingredients into a dry sheet of paper at speeds that may be as high as a half mile per minute.The most common method of turning recycled paper into a new sheet of paper is by the use of the Fourdrinier machine. It consists of a continuously moving wire belt or screen, to which the dilute papermaking slurry is fed and from which the wet, formed sheet is removed continuously. The slurry is deposited onto the wire from the sluice as a jet of uniform and proper thickness, speed, and consistency.The wet sheet at about 20% consistency (80% is water) is removed from the wire and transferred to a supporting woolen felt, which carries it through a series of press rolls. At this point, more water is removed mechanically and the sheet progresses to the drier section at about 33% consistency. The remaining water is removed by evaporation.The reuse of waste papers is common, particularly for the lower grades of paper product. Most office papers are recycled in the form of tissue product such as hand towels and bathroom tissue. Over 50% of the tissue produced worldwide is made from recycled paper. The largest supply of recycled paper is old cardboard containers (OCC), roughly 49% of all paper recovered. This grade is generally used in the manufacture of new cardboard cartons, boxboard (cereal boxes, etc), and gypsum board (the white side of sheetrock).
