ASTRAGALUS ARMATUS AS SOURCE OF FIBRES FOR PAPERMAKING
This paper deals with the study of the chemical composition and the cooking of Astragalus armatus roots, in order to produce lignocellulosic fibres. The chemical composition of this raw material has showed that it contains quite high amount of extractives in organic solvents (close to 13％), but low percentage of lignin (around 17％) and acceptable content of polysaccharide (54％), with a a-cellulose amount of about 35％. Finally, the ash content was around 3％. With the insight of such data, we have undertaken the soda-anthraquinone cooking of A. armatus roots and produced lignocellulosic fibres. Different cooking temperatures (100, 120, 140 and 160 ℃) and cooking times were tested (30, 60, 120 min). A yield of about 30％ w/w was obtained and the prepared pulps exhibited a Kappa number of around 60. Finally, the isolated fibres were used to produce paper samples with a basis weight of 60 g/m . The structural and mechanical properties of the prepared samples were close to those of other common plantsbased fibre-mats.
