Abstract

The influence of charged species on the relative bonded area (RBA) of flat shaped viscose fibre handsheets was investigated. For this purpose four samples, a reference fibre without any additives as well as three physical modified fibres, were studied. The RBA was determined by the light scattering method and by using the so called Page equation. To use the Page equation, the breaking length of handsheets, the optical bonded area of fibre-fibre joints as well as the bond strength of such fibre joints were determined. The optical bonded area was analysed by polarized light microscopy. Using a micro bond tester, the bond strength of fibre-fibre joints was determined. Both techniques, light scattering and calculation via the Page equation did not deliver absolute values for RBA. Quite contrary, they only give approximate values. However, an increase of relative bonded area due to anionic charges is clearly seen. Additionally, the breaking length is increased by both additives.
