| titleOfInvention | Method for dissolving cellulose |
| abstract | The invention discloses a method for dissolving cellulose, characterized by: using at least one from the group consisting of wood pulp, cotton pulp, hemp pulp, bamboo pulp, bagasse pulp, grass fibered pulp, cellulose non-woven fabric or steam exploded cellulose pulp as cellulose raw material, uniformly stirring the cellulose raw material, NaOH and water at a temperature of -15-50 DEG C to obtain a cellulose solution. The prepared cellulose concentrated solution has good spinnability and film forming property. The method breaks through a dissolution method of traditional gluing technology, does not relate to carbon disulfide and other substance causing serious environmental pollution, and is green and environmentally friendly. According to the invention, the cellulose raw material can be directly rapidly dissolved at room temperature, without heating or precooling a solvent. The method has the advantages of saving energy, and reducing energy consumption. By using raw materials having low cost, the method has the advantages of simple operation, small investment, high productivity, and is easy to realize large-scale industrial production. |
