| 发明名称 | Method for producing modified cellulose | ||
| 摘要 | The present invention provides a method for producing modified nanofibrillated cellulose characterized by bringing cellulosic material into a fiber suspension, adsorbing a cellulose derivative or polysaccharide or polysaccharide derivative onto fibers in said fiber suspension under special conditions and subjecting the obtained fiber suspension derivative to mechanical disintegration. A modified nanofibrillated cellulose obtainable by a method of the present invention is provided. Furthermore, the invention relates to the use of said modified nanofibrillated cellulose. | ||

| 主权项 | 1. A method for producing modified nanofibrillated cellulose, comprising: preparing a suspension containing fibers from cellulosic material; adsorbing a cellulose derivative or polysaccharide or polysaccharide derivative onto the fibers in said suspension under special conditions; and subjecting the fiber suspension comprising said cellulose derivative or polysaccharide or polysaccharide derivative to mechanical disintegration; to obtain modified nanofibrillated cellulose modified with said cellulose derivative or polysaccharide or polysaccharide derivative. | ||
