| 发明名称 | Process for the production of nano-fibrillar cellulose gels | ||
| 摘要 | The present invention relates to a process for the production of nano-fibrillar cellulose gels by providing cellulose fibers and at least one filler and/or pigment; combining the cellulose fibers and the at least one filler and/or pigment; and fibrillating the cellulose fibers in the presence of the at least one filler and/or pigment until a gel is formed, as well as the nano-fibrillar cellulose gel obtained by this process and uses thereof. | ||

| 主权项 | 1. A process for the production of a nano-fibrillar cellulose gel comprising the steps of: (a) providing cellulose fibres; (b) providing a filler; (c) combining the cellulose fibres of step (a) and the filler of step (b); and (d) fibrillating the cellulose fibres and the filler from step (c) until a nano-fibrillar cellulose gel is formed, wherein the filler is calcium carbonate, and wherein in step (d) the weight ratio of fibres to filler on a dry weight basis is from 1:33 to 10:1. | ||
