PURPOSE:To obtain the titled uniform compound useful as a water-absorbing material, etc., by dissolving an alkali hydroxide in a mixed solvent of an organic solvent such as isopropyl alcohol, etc. and water, having a specific composition, to give a solution for making an alkali cellulose, bringing it continusouly into contact with a sheet cellulose. CONSTITUTION:0.001-0.5wt% alkali hydroxide is dissolved in a mixed solvent of 80-96pts.wt. organic solvent such as isopropyl alcohol, t-butyl alcohol, n- butyl alcohol, acetone, methyl ethyl ketone, etc. and 20-4pts.wt. water to give a solution for making an alkali cellulose, which is prepared in the tank 11. It is fed from the feed inlet 6 for the solution making an alkali cellulose to the container 6 for making an alkali cellulose, and it is continuously brought into contact with the sheet cellulose 14 introduced from the rolls 4 at the inlet of the container 1 for making an alkali cellulose, and the sheet is taken out through the sealing roll 5 to the outside of the container 1 to give the desired sheet alkali cellulose 15. |
