The timber resources used to make wood pulp are referred to as pulpwood. While in theory any tree can be used for pulp-making, coniferous trees are preferred because the cellulose fibers in the pulp of these species are longer, and therefore make stronger paper. Some of the most commonly used softwood trees for paper making include spruce, pine, fir, larch and hemlock, and hardwoods such … Webb1 sep. 2005 · Corpus ID: 101679261; Pitch Control in Thermomechanical Pulping and Papermaking by Enzymatic Treatments @article{Blanco2005PitchCI, title={Pitch Control …
