Fibre dimension studies of five Bangladeshi woods, namely, Moluccana koroi (Albizia falcataria), kainjal (Bischofia javanica), jialbhadi (Lannea coromandelica), narikeli (Pterygota alata) and chundul (Tetrameles nudiflora) wets carried out to find out their suitability in paper making. From the data, Runkel ratio, flexibility co-efficient and relative fibre length, which influence certain pulping properties, were deduced. Attempts were made to correlate fibre dimensions to pulping properties of certain species namely, Moluccana koroi and Kainjal. Considering the fibre length and certain anatomical characteristics, the potentiality of narikeli for pulping has bee suggested. It is concluded that fibre dimensions along with pulping properties and the manufacturing processes should be the guiding principles in evaluating the suitability of the species in paper making.
