PROCESS FOR THE PRODUCTION OF MICROFIBRILLATED CELLULOSE AND PRODUCED MICROFIBRILLATED CELLULOSE |
摘要 |
A process for treating cellulosic fibers comprises mechanically pre-treating the fibers followed by treating the fibers with an enzyme and thereafter mixing the fibers with a solution comprising an alkali metal hydroxide followed by mechanically treating the fibers to form microfibrillated cellulose. In this way it is possible to produce microfibrillated cellulose (MFC) in an improved and energy efficient way. |
