Abstract:
The present invention relates to a method for manufacturing an intermediate product that can be stored and transported and efficiently converted into microfibrillated cellulose with limited energy input at the time of conversion. More specifically, the invention involves the use of dewatered carboxymethylcellulose or carboxylated cellulose fiber having a low degree of substitution and a high amount of additives.
