Abstract

The pulping of RICE STRAW with DIETHYLENE GLYCOL, DIETHYLENE GLYCOL + ETHYLENE GLYCOL and DIETHYLENE GLYCOL+ ETHYLENE GLYCOL + 2% NaOH was studied in order to investigate the effects of the cooking variables (temperature and different organic solvent mixtures) on the properties of obtained pulp (cooking yield, Kappa number, freeness (CSF)) and paper (breaking length, burst index, folding endurance, tear index). Delignification was increased by increasing the temperature and hand sheet papers with better bondability of fibres were obtained, but the strength or length of the fibres with increasing temperature were decreased. With the use of 2% sodium hydroxide in cooking solvent papers with superior mechanical properties were obtained. Properties that are sensitive to bondability of fibres, such as, breaking length, burst index, folding endurance, were increased with increasing of temperature, but another property sensitive to length or strength of fibres, that is, tear index, was decreased with increasing of temperature.
