From Tree to Page: The Papermaking Process from Wood Chips

Wood chips are obtained from trees that have been harvested for their wood. Softwood trees such as pine, spruce, and fir are commonly used in papermaking due to their long fibers, which produce strong paper. The wood chips are processed to remove any impurities, such as bark or knots, before they are used to make paper.

Pulping is the first stage of the papermaking process. In mechanical pulping, the wood chips are ground into pulp using mechanical force, while chemical pulping involves using chemicals to dissolve the lignin in the wood chips and separate the fibers. The resulting pulp is then washed and bleached to remove any impurities and achieve the desired color.

Next, the pulp is mixed with water and other chemicals, such as fillers, sizing agents, and retention aids, to create a paper stock that is suitable for papermaking. The paper stock is then fed onto a paper machine, which consists of several sections, including the headbox, wire section, press section, and dryer section.

The headbox is where the paper stock is deposited onto the wire section, which is a continuous belt made of mesh that allows water to drain through. The press section removes excess water from the paper by pressing it between rollers, while the dryer section uses heat and air to dry the paper.

Once the paper has been dried, it is passed through a series of finishing processes to improve its appearance, strength, and other properties. These processes may include calendering, coating, and reeling, among others.
