Among woods of Algerian broadleaves trees there are some which can play a very important economical role, mainly, Oak and poplar that may constitue a source of cellulosic fibres. The present study deals with the behaviour of these, during the process of sulphate cooking, the so-called Kraft process, using soda and sodium sulphide as cooking agents. Oak and poplar show a very interesting behaviour for the cellulosic industry in comparison with the pulp yield and the Kappa index obtained in relation to the optimal cooking time. Thus, it follows that the Quercus rotundifolia wood gives higher yield compared to the genus Populus known for its low density. The pulps have are characterised at the morphological level on the basis of their fibres length, fibres width, coarseness as well as their felting index with the aim of a complete valuation of the fibres of each of these species. Kraft process, cooking, wood, Quercus roturdifolia, Populus alba, Populus nigra,, yield, kappa index, fibres, coarseness, length, width.
