| description | The invention discloses a method for regulating and controlling the crystallinity of regenerated cellulose, which comprises the step of preparing the regenerated cellulose by using low-molecular-weight cellulose and common cellulose as raw materials through a dissolution regeneration method. Based on the excellent characteristics that the low-molecular-weight cellulose is easy to crystallize and the size of a crystal region is small, the crystallinity and the crystal size of the regenerated cellulose can be simply and accurately regulated and controlled by adding the low-molecular-weight cellulose into a common cellulose solution and regulating and controlling the polymerization degree and the proportion of the low-molecular-weight cellulose. The low-molecular-weight cellulose is compounded in the common cellulose solution, so that the crystallinity of the prepared regenerated cellulose is obviously increased, and the crystal size is relatively small. According to the method, the crystallinity and the crystal |
