Paper towels are made in exactly the same method as any recycled papers are made. The first step involved in making recycled paper towels is collecting the paper needed in the process, usually in homes and businesses and they are transported to paper recycling centers.
During the recycling, the paper bales will be placed on conveyor belt and they are carried into large tank that is full of chemicals and water. The paper is soaked in the container, cutting them into small pieces and heated into the paper turns back to pulp. The pulp consists of water and plant fibers from which the paper was made originally. The pulp will be forced through series of screens in order for any impurities and contaminants like glue, plastic bits that are left behind to be removed.
After screening, the pulp will be cleaned in centrifugal cleaner and this spins the pulp rapidly that cause the material denser then paper fibers to be spun right outside and rejected. This procedure can help remove debris little enough so it can pass through the hole in screening processes like stapes.
The next step is deinking which is a two-step process. The small particles of ink are rinsed away and the larger ink particles are taken away with the flotation process. In this process, the paper pulp will be placed in large container, forcing the hydrogen through the pulp. This can help loosen the ink particles, allowing them to float to the tank top where they are removed.
When the pulp is already free of ink, it will now be refined. The process of refining the paper pulp implies kneading the pulp until such time that the fibers swell. Kneading can break apart the large clumps of fibers which may be stuck together. Dye is added during this time if the maker wishes to color the paper, or white paper is also bleached during this time. Most of the time, paper destined to become paper towels and napkins is left in its natural brown color.
Then the recycled paper is ready to be turned back to paper product after the refinement process is completed.
