摘要

The present invention relates to a method for producing dewatered microfibrillated cellulose (MFC) comprising i) providing an aqueous MFC slurry, ii) optionally dewatering said MFC slurry by mechanical means to provide a partly dewatered MFC slurry, and iii) subjecting the MFC slurry or the partly dewatered MFC slurry to one or more drying operations by means of one or more absorbing materials to produce dewatered MFC. The produced MFC can be redispersed in water without deteriorating the material properties of the MFC.
