Modelling and simulating the floating fibres movement during drafting

Abstract

A mathematical model of floating fibre motion has been established through analyzing the forces acting on it, and then the fibre movement under various conditions is simulated by computer simulating calculation. The results show the speed change point distribution with different statistical characteristics under various processing conditions, which have been

obtained before only through the experiments. In addition, the effects of frictional force distribution, fibre length, roller distance and drafting ratio on the speed change point distribution have also been studied respectively from the simulation results. It provides a new way for studying the movement of floating fibres in the drafting zone.
