Tensile Strength of Wet Granular Materials
Nature, 1967RECENT correspondence1–6 has dealt with the tensile strength of random sphere packings in the pendular range. The essential difficulty is that the cohesion between individual spheres due to the liquid bridge decreases as the liquid bridge increases in volume.

Recovered paper is the most important raw material in the world for the production of paper and paperboard (Hoke, 2009). The availability of recycled fibre is coming under pressure from competition for biomass for different uses, such as construction materials, biorefinery applications and the production of energy (Hoke, 2009).

Paper is a layered mat consisting of a network of cellulose fibres bonded together. Each of the fibre-fibre contacts is held together by intermolecular forces (van der Waals; hydrogen bonding) which are very sensitive to water, the extent of bonding decreasing steadily as the water content of the paper increases [1], The water wets the fibres which ...

Simulated strength of wet fibre networks
Journal of Pulp and Paper Science, 2007Computer simulations were employed to study the behaviour of wet webs under tensile load. Web behaviour is modelled at the fibre level, where dynamics of fibre motion are determined by fibre stiffness and such interactions as adhesive forces and interfibre friction.

WET-STRENGTH FINISHING AGENTS FOR PAPER
2002The invention relates to wet-strength finishing agents for paper, containing a) between 1 and 99.9 wt. % of a water-soluble polamidoamine which is cross-linked with an epihalohydrin, and b) between 0.1 and 20 wt. % of at least one other cationic polymer.
