To provide the technology enabling is to mass-produce pure paper made of 100% non-wood pulp without using wood pulp from the view point of the protection of global environment, in consideration of the fact that bagasse pulp has largely been used as a principal raw material when mass-producing pure paper made of non-wood pulp at a low cost but soft wood pulp excellent in various kinds of strength has been blended as binding pulp since conventional bagasse pulp is short of various kinds of strength.

This method has three processes in combination with one another: (1) cutting stems of millets diagonally and parallel to one another to subject them to sap removal and depithing so as to acquire long rinds; (2) treating the rinds with an alkaline cooking liquor to acquire pulp having various kinds of strength such as tear strength; (3) blending it as binding pulp with bagasse pulp used by the conventional method, followed by making paper.
