Abstract

The invention relates to a method for manufacturing paper pulp (10), in which method bleached, chemically pulped cellulose fibres (1) from hardwood are used as raw material. The method comprises extracting (5) xylan from said cellulose fibres (1) by means of sodium hydroxide; adding carbon dioxide into a mixture (2) containing said cellulose fibres (1), dissolved xylan and sodium hydroxide, for precipitating xylan; adding calcium hydroxide into said mixture containing precipitated xylan and cellulose fibres, for forming precipitated calcium carbonate (7); and removing sodium hydroxide from said mixture (4) containing sodium hydroxide, xylan, cellulose fibres (1), and calcium carbonate. Furthermore, the invention relates to paper pulp made by the method.
