  • The Pulp and Paper Making Processes - Princeton University

    The pulping process is an important link in the papermaking industry. To learn why it is important, we have to start from the pulp. Paper pulp can be classified mainly into two types by the pulping methods: chemical pulp and mechanical pulp. The chemical pulp is produced through the chemical pulping process, while the mechanical pulp is produced through mechanical pulping.
