A number of ethanol (EtOH)-water based pulping trials was carried out to produce a jute pulp with low residual lignin content and high physical properties. The effects of pulping conditions on the yield, degree of delignification and selected physical properties were evaluated. It was found that the delignification ability of ethanol-water system for jute was moderate at low temperatures. It was necessary to use high temperature and longer cooking times to give sufficient delignification. However, the extended delignification with increasing temperature, strongly affected the strength properties. The highest burst strength of 1.8 kPa m(2)/g, tear strength of 9.6 mN m(2)/g and tensile strength of 32.3 N m/g were found at various reaction times and temperatures in ethanol (EtOH)-water pulping trials.
