| Abstract | This study deals with the determination of chemical composition and the study of the pulping and paper making potentialities of banana pseudo-stems growing in Thailand. The fiber morphology and chemical compositions of the raw material were studied. The lignin and extractive content was found low. The only discouraging finding was the relative high amounts of ash (approximately 16%) and water solubility (approximately 15%) of raw material. Banana stem was cooked by Kraft process with different chemical charges and a wide range of time and temperature and the optimal pulping conditions were established. The best cooking condition of banana stem fiber was found with a low alkali charge (12 to 14) %, at 170°C temp. for 120 minutes to the kappa number around 25, with the yield of around 40 % and with a medium viscosity. Unbleached banana kraft pulp in the kappa number range of 23-28 was not easy to bleach with three stages sequence of D0EpD1. The brightness was achieved 45 % ISO, with a viscosity level at 585 ml/g. Drainage of pulp was extremely slow and paper making properties was characterized by low strength, low bulk, rough surface and extremely poor optical properties. |
