Through the 18th century the papermaking process remained essentially unchanged, with linen and cotton rags furnishing the basic raw materials. Paper mills were increasingly plagued by shortages; in the 18th century they even advertised and solicited publicly for rags. It was evident that a process for utilizing a more abundant material was needed.

The process of pulping, which turns raw materials like wood chips or recycled paper into pulp slurry, is a basic one in the production of paper. Mechanical and chemical pulping are the two main types. While mechanical pulping separates fibers from raw materials by grinding them, it may not be appropriate for all types of paper.
