  2. Typical properties of the three pulps

  3. MFC-Lyocell Microfibrillated Fiber

  4. Process for Papermaking • The MFC from Engineered Fibers technology, LLC. was dispersed into 1.65% solution • Some of the MFC were refined by Hollander beater equipment • 6% the MFC or refined MFC was added into 3% consistence pulp, and stirred and mixed together • Handsheets were produced by the stand TAPPI process-TAPPI T205sp-95 as well

  5. The effect of refining process on the MFC’s properties

  6. The effect of Microfibrillated Cellulose on Paper Properties

  7. The effect of Microfibrillated Cellulose on Paper Properties

  8. The effect of Microfibrillated Cellulose on Paper Properties

  9. The effect of Microfibrillated Cellulose on Paper Properties

  10. Conclusions • MFC can improve the tensile strength, water absorption capacity-Cobb value and vapor transfer ability (MVTR) of paper, which was made from hardwood and softwood fiber, especially tensile from softwood increased ~26-30%, vapor transfer ability-MVTR from hardwood improved ~12%; water absorption capacity improved ~8-30% • Refining process can further improve MFC’s efficiency, particularly for tensile and water absorption ability increased ~10%. However, the efficiency of refining process is limit. It therefore should design and develop some new processes to improve MFC’s efficiency.
