Description
This paper reports experimental data about
wood chemical composition (extractives and
lignin content), fibre characteristics, kraft cooking
behaviour and papermaking potential of two
wood samples of Eucalyptus globulus (one
industrial chip sample and another obtained
from a clone tree). The samples were submitted
to the kraft cooking and bleaching processes in
order to evaluate its pulping potential. The
experimental results showed that the clone tree
requires milder cooking conditions and exhibits
higher pulp yield. The pulp fibres obtained from
the clone have higher fibre length and fibre width
and lower coarseness, which give higher fibre
flexibility and collapsibility. In consequence,
structural, mechanical and optical properties of
paper are significantly different. In addition, we
observed that the fibres from the clone tree are
weaker than the corresponding fibres from the
industrial sample.
