  1. 2007 International Conference on Nanotechnology for the Forest Products Industry, June 13-15, 2007, Knoxville, TN  Microcrystalline Cellulose (MCC) for Papermaking and Surface sizing Yong Zou, and Jeffery S.

  2. Typical properties of the two pulps

  3. Process for Papermaking • The MCC from FMC was dispersed into 5% solution • 5% the MCC vs. dry fiber was added, after mixing, which makes into 1.2% consistency pulp. • Handsheets were produced by the stand TAPPI process-TAPPI T205sp-95 as well

  4. The effect of MCC on Paper Properties

  5. The effect of MCC surface sizing

  6. The effect of MCC surface sizing

  7. Surface sizing of MCC • Two Paper: S-1311 from ULine. 24’’ 50LB paper A; and S-8514 from ULine 24” 50LB paper B • Two additives: MCC (1.4 and 2.8%) and Polyester resin (5% and 10%) • Experimental Method: Yates’ Algorithem: • X1=MCC 1.4% (-) and 2.8% (+) • X2=Polyester resin 5% (-) and 10% (+) • X3=paper Paper B (-) and paper A (+)

  8. Tensile-Theeffect of MCC surface sizing X1-MCC; X2-PGLR-25; X3-paper

  9. Water Absorption -The effect of MCC surface sizing X1-MCC; X2-PGLR-25; X3-paper

  10. Conclusions • MCC can improve paper tensile strength and water absorption capacity, particularly water absorption capacity, based on three methods-papermaking, single surface. sizing and combining Polyester resin; the efficiency in papermaking is much better than surface sizing, especially for softwood. • Confirm environmental-friendly polyester can increase paper strength, but decrease water absorption capacity.
