Abstract
The elongation of the typical wood fibres used in
papermaking is in the range of 1 to 5%, so as for the
paper made of such fibres These values seem to be
extremely low in comparison with the common plastics such
polyethylene, polypropylene and polyester in which
elongation is measured in 100%-s magnitude. The low
extensibility of paper is limiting use of paper in
engineering and packaging applications despite on the
relatively high strength. Extensibility of paper can be
improved by manipulations with fibre structure, character
of interfibre bonding, and structure of the fibre
network. The question is whether these can be done
simultaneously in the frame of the papermaking process?
This work aims to provide a deep outlook on the
extensibility of paper by reviewing the key factors
affecting it. The combined approach for the improvement
of extensibility of paper was suggested based on these
considerations. Mentioned approach unites several methods
including: mechanical treatment of fibres, addition of
agar, compaction and low-restrain drying of paper. As a
result of these treatments extensibility of paper can be
increased up to 15% for uniform sheets and up to
30%-points for oriented paper.
