Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, Paper formed through such process is usually brown (can also be bleached to produce white paper) and is coarse in texture. Bleached kraft papers have about 15% less strength and higher cost compared to Virgin Kraft, but they are used where improved cleanliness or high-quality printing is
desired.
