The effect on the physical properties of TMP handsheets by adding microfibrillated cellulose (MFC) is investigated. 26 TMP handsheet series were made with 4% addition of MFC produced by grinding or homogenization. Analysis of particle size distribution of the MFC showed that homogenization yields a bimodal distribution curve, while grinding gives a log normal distribution. The produced MFC had hydrodynamic particle sizes in the range 30–150 μm, and homogenization produced MFC with the largest…

Effect of Bleached Eucalyptus and Pine Cellulose Nanofibers on the Physico-Mechanical Properties of Cartonboard
Extending the limits of paper recycling by increasing the number of recycling cycles results in decreased mechanical properties due to the irreversible hornification of cellulose fibers. This process
Fluting medium strengthened by periodate–chlorite oxidized nanofibrillated celluloses
Nanofibrillated cellulose (NFC) has potential for use as a strength-enhancing additive in paper and paperboard applications. In this work, the effect of NFC on the mechanical and air resistance


Microfibrillated cellulose: morphology and accessibility
Microfibrillated cellulose (MFC) is prepared by subjecting dilute slurries of cellulose fibers to repeated high-pressure homogenizing action. A highly microfibrillated product will have a gel-like
Nano-fibrillation of pulp fibers for the processing of transparent nanocomposites
Pulp fibers were fibrillated uniformly into nano-sized fibers using a grinder with a specially designed set of grinding disks. To investigate the effect of the fibrillation through the grinder on the
Thermoplastic Nanocomposites Filled With Wheat Straw Cellulose Whiskers. Part II: Effect of Processing and Modeling
The reinforcing effect of cellulose microcrystals, or whiskers, dispersed in a thermoplastic matrix is analyzed. In Part I [Polym. Compos., 17, 604 (1996)], the preparation and the characterization
The influence of mechanical pulp quality on the properties of filler-containing papers
The main part of this paper presents a study of the influence of the character of the mechanical pulp on the way a furnish responds to filler addition. Six different mechanical pulps were studied in
