METHOD FOR PRODUCING CELLULOSE-FIBER FLAT STRUCTURE |
摘要 |
The present invention relates to a method of producing a cellulose-fiber flat structure, the method including obtaining a cellulose-fiber flat structure by filtering a fine cellulose-fiber dispersion containing fine cellulose fibers having an average fiber diameter of 4 to 100 nm, using a filter material having a water permeability of not more than 100 ml/m2·s and an initial tensile modulus of 20 MPa or greater. The present invention is able to produce a cellulose-fiber flat structure by efficiently recovering fine cellulose fibers from a dispersion containing fine cellulose fibers having an average fiber diameter at the nano level. The method of producing a cellulose-fiber flat structure can also be applied to a continuous process. |
