How toilet paper is made
Toilet paper is made from virgin wood fibers or a combination of recycled paper pulp mixed in water with chemical sulfates to break them down, starches that create moisture. Starch and chemicals to whiten it.
Virgin fiber toilet paper is made from both softwood and hardwood. Softwood trees are southern and Douglas firs. These have long fibers that give the paper strength. Hardwood trees like maple and oak have shorter fibers that make the paper soft.
Toilet paper made from virgin fiber is made from a combination of approximately 70% hardwood and 30% softwood.
Toilet paper production
- The trees are cored and cut into small pieces.
- The wood chips are mixed with water and chemicals to create a slurry.
- The slurry is fed into a pot called a digester.
- The Die Slurry is boiled, which evaporates the moisture, leaving a batch of fresh cellulosic fibers called pulp.
- The pulp is washed to remove lignin, the yellow glue that binds the fibers and cooking chemicals together.
- Young dissolving pulp undergoes a bleaching process to extract color from the fibre
- Pulp is mixed with water to produce paper that is 99.5% water and 0.5% fiber.
- The stock is sprayed between moving mesh screens, allowing much of the water to drain away.
- A wide mat of fibers is passed through a large heated cylinder called a Yankee dryer.
- Toilet paper is pressed and dried to a final moisture content of about 5%.
- The paper is creped so that it becomes smooth and wrinkled.
- During creping, becomes scraped the paper off the Yankee dryer with a metal blade to make large, wide sheets.
- Sheets are rolled into large rolls and sent to converting machines.
- Toilet paper is unrolled, cut and wound into a long, thin cardboard tube, creating a roll of paper.
- The paper logs are then cut into rolls and wrapped into bundles.
Recycled paper is made from existing colored and white paper mixed with water and chemicals and boiled in a pulper and mashed. It is rinsed, cleaned and bleached before entering the Yankee Cylinder
papermaking process.
