Abstract:
The chemical composition, fiber morphology and pulping properties of mulberry (Broussonetia papyrifera (L.) Vent) bark in the dry and hot areas of Jinsha river were investigated. It showed that this tree species may be an ideal raw material in fiber and pulping industries because of long wood fiber, low lignin content and high fiber content as well as favorable fiber morphology. Comparisons of three varieties demonstrated that the red bark variety had the best pulping property because it had the highest content of fiber (67.48%), the longest fiber(13.54mm) and the desired proportion value for length to width (728). The white flower-variety was the second to the red bark variety but it had relatively high integrated economic value. Although the red flower-variety could be used as raw material, its paper pulp quality was not as good as those of the formers. Both the red bark variety and white flower varieties gave priority to the development of pulping industry in the local regions.
