Fibre-to-Fibre Contacts in Nonwovens

Fibre-to-fibre contacts have been regarded as the corner stone of micromechanics of fibrous assembly. This study systematically rebuilt all geometrical models. The curved fibre paths were approximated by the chords of fibre segments. The occupied space of two contact fibre segments were modelled incorporating the surface yield at the contact point. A three-dimensional model was used to replace previous planar geometry in computing the contact probabilities of individual fibre segments in a contact sequence. On the basis of the above modified geometrical model, an improved stochastic model was thus developed to estimate fibre-to-fibre contacts in nonwowens.
