How paper is made
Gabriele Buchignani
Step-By-Step guide to paper process
The Paper Making Process
The following video shows the paper process. The whole process is divided into 7 parts.
Paper processes
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 materials density
6) Drying to eliminate the density of materials
7) Finishing procedure to provide a suitable surface for usgae
There're also:
- Real-time quality control
- Paper testing
Paper production
Pulp and paper manufacturing process in the paper industry
Raw materials
Wood and bamboo
Separation of Fiber
Final separation of the fibre is accomplished by a breaking process in which the brittle woody portion of the straw is broken, either by hand or by passing through rollers, followed by the scutching operation, which removes the broken woody pieces (shives) by beating or scraping.

Bleaching Process
Bleaching of wood pulp
Leaching is the treatment of cellulosic fiber with chemicals to increase brightness. Brightness may be achieved by either lignin removal (delignification) or lignin decolonization. Lignin remains a major constituent of pulp even after digestion by chemical pulping.
