Abstract 1. A METHOD OF MANUFACTURING PAPER AND VISCOSE PULP HAVING IMPROVED WATER-ABSORPTION PROPERTIES ACCORDING TO SCAN-P-13:64, IMPROVED SOFTNESS, AND IMPROVED RESISTANCE TO ALKALI ACCORDING TO SCAN-C2:61, WHICH COMPRISES REACTING CELLULOSE PULP WITH AN ALKALINE AQUEOUS SOLUTION CONTAINING ALKALI IN AN AMOUNT OF AT MOST ABOUT 2.1% BY WEIGHT OF THE SOLUTION AND FROM ABOUT 0.5 TO ABOUT 12% BY WEIGHT OF THE DRY PUPL, AND A CROSS-LINKING AGENT SELECTED FROM THE GROUP CONSISTING OF POLYHALIDES, POLYEPOXIDES, AND EPOXYHALIDES IN AN AMOUNT WITHIN THE RANGES FROM ABOUT 0.05 TO ABOUT 8.8% BY WEIGHT OF THE SOLUTION AND FROM ABOUT 0.5 TO ABOUT 50% BY WEIGHT OF THE DRY PULP, AT A TEMPERATURE OF BETWEEN 25*C. AND 95* C. AT WHICH CROSS-LINING OF THE CELLULOSE TAKES PLACE, FOR A PERIOD OF TIME SUFFICIENT TO INCREASE RESISTANCE TO AN 18% AQUEOUS SODIUM HYDROXIDE SOLUTION BY FROM ABOUT 1 TO ABOUT 16%.
