Abstract:
(EN) This method for producing an anionically-modified cellulose nanofiber dispersion liquid includes a step for preparing a dispersion liquid containing an anionically-modified cellulose, and a step for defibrating the cellulose in the dispersion liquid, wherein the hydroxy groups of at least a portion of the pyranose rings of the anionically-modified cellulose are modified by an oxidation or substitution reaction, and the anionically-modified cellulose dispersion liquid to be subjected to the defibration has an electrical conductivity of 500 μS/cm or less at a concentration of 1.0 wt%. The dispersion liquid is highly transparent.
(FR) La présente invention concerne un procédé de production d’un liquide de dispersion de nanofibres de cellulose à modification anionique qui comprend une étape de préparation d’un liquide de dispersion contenant une cellulose à modification anionique, et une étape de défibrage de la cellulose dans le liquide de dispersion, les groupes hydroxy d’au moins une partie des cycles pyranose de la cellulose à modification anionique étant modifiés par une réaction d’oxydation ou de substitution, et le liquide de dispersion de cellulose à modification anionique devant être soumis au défibrage présente une conductivité électrique de 500 µS/cm ou moins à une concentration de 1,0 % en poids. Le liquide de dispersion est hautement transparent.
(JA) アニオン変性セルロースを含む分散液を準備する工程、および当該分散液中の前記セルロースを解繊する工程を含む、アニオン変性セルロースナノファイバー分散液の製造方法であって、前記アニオン変性セルロースの少なくとも一部のピラノース環の水酸基が、酸化または置換反応により変性されており、前記解繊に供するアニオン変性セルロース水分散液の1.0重量%濃度における電気伝導度が500μS/cm以下である、製造方法。当該分散液は高い透明性を有する。
