A METHOD FOR DISSOLVING CELLULOSE AND A CELLULOSIC PRODUCT OBTAINED FROM A SOLUTION COMPRISING DISSOLVED CELLULOSE

摘要

The present invention relates to a method for dissolving cellulose. The method comprises -introducing cellulosic raw material, -treating the cellulosic raw ma-terial in an enzymatic treatment process, -mixing the cellu-losic raw material after the enzymatic treatment in an aque-ous solution in order to obtain an aqueous intermediate product containing the cellulosic raw material of at least 3.5 wt.-%, alkali metal hydroxide between 3.5 wt.-% and 7 wt.-% and zinc salt, -freezing the intermediate product to a solid state, and -melting the frozen intermediate product. The present invention also relates to a cellulosic product obtained from a solution comprising dissolved cellulose.
