摘要

For any type of pulping process, the chemical composition of raw materials is the determining factor of pulping yield, while fiber dimensions establish the pulp strength and dictate its final use. In this study, an attempt was made to present the chemical and morphological characteristics of Brassica napus stalk fibers. The chemical compositions of raw material and Kraft-delignified fibers were analyzed for the macromolecular substances content (cellulose, hemicelluloses, pentosans, and lignin) and low-molecular-weight components (extractives, soluble, inorganic). With regard to morphology features, such as fiber length, width, and wall thickness of pulp, samples were measured using digital microscope system and scanning electron microscope. It is concluded that the properties of rapeseed stalk fibers, which are commonly encountered in other nonwood and hardwood paper-making fibers, have the potential for being used for manufacturing different paper products.
