Abstract
138,911. Soc. Anon. des Etablissements A. Olier. Feb. 11, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Materials, fibrous; pulp, preparation of.-In the preparation of cellulose for paper-making from fibrous plants such as maize, alfa, dwarf-palm, papyrus, and urena lobata, the stalks and leaves are cut up, crushed, and washed, and then treated by steam at 2-3 kgs. pressure for one hour in a digester, condensation water being drained away and taking with it parenchymatous cellulose and soluble matters such as gums and pectates. The cellulose fibres swell up, and the cement is partly dissolved. The drain-cock is then closed, and 12 per cent caustic soda introduced and circulated by a Koerting injector, or by using a digester of the vomiting type, or by other means, the operation being conducted for 3 hours at 2-3 kgs. pressure. The product 's washed, broken in a beating-engine or small mill, and bleached, and may be used for half-pulp paper such as packing-paper. Semi-chemical pulp may be obtained by substituting slaked fat lime for the caustic soda, and, by partial bleaching of the half-pulp so produced, a pulp suitable for newspapers is obtained. Alkali materials may be recovered by evaporation and re-causticized.
