    from wood‚ a chemical pulping process separates lignin from cellulose fibers. This is accomplished by dissolving lignin in a cooking liquor‚ so that it may be washed from the cellulose fibers. This preserves the length of the cellulose fibers. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper. This is because they do not contain lignin‚ which deteriorates over time. The pulp can also be bleached to produce white paper‚ but this consumes 5% of
