Distribution of strain to failure of single wood pulp fibres

, 2001
The single-fibre composite test has been applied to characterize the distribution of strain to failure of individual fibres from unbleached softwood kraft pulp. The fibre was moulded into a thermoset matrix which is subjected to a tensile test, whereupon

Surface lignin on kraft wood pulp fibres

, 2003
A systematic study of the surface lignin of kraft wood fibres is reported in this thesis. The existing X-ray photoelectron spectroscopy (XPS) methodologies for surface lignin analysis were critically evaluated, and a modified XPS methodology was ...

ESTUDO DA BRANQUEABILIDADE DA POLPA KRAFT DE EUCALIPTO

Ciência Florestal, 2015
The aim of this study was to evaluate how the pulp bleachability ability is correlated with the wood chemical characteristics, the cooking conditions, the kappa number of the brown pulp and the bleaching sequences, based on the pulp bleached brightness ...

The role of xylan and glucomannan in yellowing of kraft pulps

, 1995
The effects of xylan and glucomannan on the thermal stability of unbleached, partially bleached, and fully bleached pine and birch kraft pulps were studied.  The choice of bleaching chems. strongly affected the brightness reversion.
