The manufacturing method of microfibrillated cellulose， and microfibrillated cellulose

The invention relates to a method for producing microfibrillated cellulose， where a suspension comprising cellulose derivative in a liquid phase which comprises an organic solvent is provided. The suspension of cellulose derivative is mechanically treated and microfibrillated cellulose is obtained. At least a part of the liquid phase from the microfibrillated cellulose is separated and microfibrillated cellulose with a dry solids content of > 30 weight-% is obtained.

本发明涉及一种微纤化纤维素（microfibrillated cellulose）的制备方法，该方法先提供一种悬浮液，该悬浮液以含有机溶剂的液相为介质且包含纤维素衍生物。随后对该纤维素衍生物悬浮液进行机械处理以获得微纤化纤维素，再将微纤化纤维素所附带的液相至少部分分离，最终得到干物质含量大于30重量%的微纤化纤维素。本发明涉及一种微纤化纤维素（microfibrillated cellulose）的制备方法，该方法先提供一种悬浮液，该悬浮液以含有机溶剂的液相为介质且包含纤维素衍生物。随后对该纤维素衍生物悬浮液进行机械处理以获得微纤化纤维素，再将微纤化纤维素所附带的液相至少部分分离，最终得到干物质含量大于30重量%的微纤化纤维素。
