This paper reports experimental data aboutwood chemical composition (extractives andlignin content), fibre characteristics, kraft cookingbehaviour and papermaking potential of twowood samples of Eucalyptus globulus (oneindustrial chip sample and another obtainedfrom a clone tree). The samples were submittedto the kraft cooking and bleaching processes inorder to evaluate its pulping potential. Theexperimental results showed that the clone treerequires milder cooking conditions and exhibitshigher pulp yield. The pulp fibres obtained fromthe clone have higher fibre length and fibre widthand lower coarseness, which give higher fibreflexibility and collapsibility. In consequence,structural, mechanical and optical properties ofpaper are significantly different. In addition, weobserved that the fibres from the clone tree areweaker than the corresponding fibres from theindustrial sample.
