Through-air bonding is one of the thermal methods of bonding fibres in the production
of non-woven webs. A computational study of the formation of bond point between
two bicomponent fibres during the through-air bonding process is reported in this paper. The
computational method involves solving the Navier–Stokes equations for two-phase flows of air
and molten polymer in a three-dimensional configuration. The heating, melting, and bonding of
fibres are modelled by the volume of fluid model together with a melting model. The simulated
results show the formation of the bond between two fibres in contact and the change of shape of
the bond with time at different bonding temperatures. The computation shows that the rate of
bonding increases slightly at higher temperature.
