Method for producing dry cellulose and dry cellulose-containing material, and re-swellable cellulose product produced by the production method

摘要

The object of the present invention is to technology cellulose and cellulose-containing materials in as short a time as possible without destructive stress on the cellulose and without losing the stability and effectiveness of additives such as drugs. Drying at no cost, and re-swelling the cellulose and cellulose-containing material, if necessary, almost completely with the original structure and density. According to the present invention, a cellulose or cellulose-containing material prepared for the purpose of drying and obtaining a swellability that can be almost completely reconstituted in the structure and density of the cellulose is suitable for moisture binders, in particular osmotic pressure and / or moisture absorption. On the other hand, it receives an effective adsorption effect of the solution and is dried regardless of the change in the structure of the material. [Selection figure] None
