Abstract [en]

The objective in this work was to develop a methodology for producing mechanical pulp based nano-ligno-cellulose (NLC) from fines fractions. Also there has been a great deal of enthusiasm to evaluate particle size distribution of NLC. In this work the crill characterisation technique was used. The crill values of TMP and CTMP based nano-ligno-celluloses were measured as a function of the homogenisation time. Results showed that the crill value of both TMP-NLC and CTMP-NLC correlated with the homogenisation time. Another objective was to utilise NLC as strength additives in paper and board grades. Laboratory sheets of CTMP and bleached kraft pulp (BKP), with the addition of their respective NLC, were made in a Rapid Kothen sheet former. It was found that handsheets of pulp fibres blended with NLC improved the z- strength and other important mechanical properties for similar sheet densities.
