METHOD FOR PRODUCING CELLULOSE NANOFIBERS |
摘要 |
Provided is a method which is capable of producing a cellulose nanofiber dispersion liquid that has a low viscosity and excellent fluidity even at a high concentration, while exhibiting excellent transparency. In a method for producing cellulose nanofibers, wherein a cellulose-based starting material is oxidized in water using an oxidant in the presence of an N-oxyl compound and a compound that is selected from the group consisting of a bromide, an iodide and a mixture of a bromide and an iodide and the thus-obtained oxidized cellulose is fibrillated and dispersed, pulp which is obtained by carrying out kraft cooking after a hydrolysis process is used as the cellulose-based starting material. |
