Summary

The adaptation of the fibre drawing model to the spin draw model requires an estimate of the heat transfer from the individual filaments in the quench system following the spinnerette. An estimate is made of the growth of the boundary layer surrounding each filament in a typical 44 filament bundle, and the corresponding heat transfer coefficients.
