What is the difference between pulp and paper?

If you want to learn the stages of paper making, you must know the difference between pulp and paper.
1. Pulp is a soft, moist material made out of wood chips and recycled paper. The pulp can be made out of recycled paper but it can also be made out of wood chips, cloth, etc. Therefore, the pulp comes first.
2. Paper is a white sheet that is made out of pulp by grinding raw material and mixing water and chemicals and then they are dried into thin sheets.

What are the stages of paper making?

The pulp is fed to a paper machine where it is formed as a paper web and the water is removed from it by pressing and drying. The stages are as follows:
1. Pulping procedure will be done to separate and clean the fibers
2. Refining procedure will be followed after pulping processes
3. Dilution process to form a thin fiber mixture
4. Formation of fibers on a thin screened
5. Pressurization to enhance the density of the material
6. Drying to eliminate the density of materials
7. Finishing procedure to provide a suitable surface for usage
