The 14th International Symposium on Cellulose Chemistry and Technology - In memoriam Academician Cristofor I. Simionescu, Iasi – Romania, September 8-10, 2010ABSTRACT. For any type of process, chemical composition is the determining factor of pulping yield, while fibers dimensions establish the pulp strength and dictates its final use. In this study, an attempt was made to provide the chemical and morphological characteristics of Brassica napus stalk fibers. Chemical composition of raw material and kraft-delignified fibers, was analyzed for the macromolecular substances content (cellulose, hemicelluloses, lignin) and low-molecular weight components (extractives, inorganic). As regards morphology features, such as fiber length, width and wall thickness of pulp, samples were measured using a digital microscope system and scanning electron microscope. It is concluded that the properties of rapeseed stalk fibers, which are commonly encountered in nonwood papermaking fibers, have the potential for the purpose of being used for making different paper products.
