Abstract
The method prepares cellulose for processing in the viscous production. Although the cellulose remains an acid, its decomposition terminates after the first day. This process is implemented in combination with the drying process. Sulphuric acid with a concentration of 0.02-0.03 per cent is added to the last washing water. Then it is pressed and dried at about 105 degrees C, cooled to normal temperature and stored for indefinite time, the first-day parameters remaining permanent.
