Abstract
Upgrading of lignocellulosic fibre materials to enhance the value or
properties of traditional fibre products and to create new applications for
fibres is a constant challenge for the fibre producing industry. The presence
of surface lignin in pulp fibres offers an interesting possibility to the use
oxidative enzymes such as laccases in targeted modification of lignin-rich
pulps. Using the novel chemo-enzymatic functionalisation method the enzymatic
radical formation is exploited for fibre activation and further bonding of
new, desired chemical components to the fibre material. Knowledge on the
functionalisation mechanisms and the factors affecting the functionalisation
of lignin-rich fibres has been generated in order to fully exploit the
potential of this novel chemo-enzymatic functionalisation method.
Hydrophobisation of wood pulp fibres, now being carried out successfully by
the chemo-enzymatic functionalisation method, is one example of the potential
modification of fibre materials. Targeted design of the
hydrophilic/hydrophobic nature of wood fibres opens up novel options both for
current and novel industrial lignocellulosic fibre applications.
