Numerical simulation of quasi-stationary ring spinning process linear elastic yarn

摘要

This article reports a theoretical investigation on the ring spinning balloon in the textile industry. Theoretical equationsnincorporating yarn elasticity are obtained, which has been ignored by most previous models. This model differs from thenearlier ones in that their choice of yarn was perfectly flexible and inextensible; those used here we presume to be morenrealistic. Discussions in this paper deal with the significance of various yarn elasticity parameters on varying yarn tensionnand balloon shape. Some results are given, from which the model seems to be very efficient and reliable in the simulationnof the ring spinning process. Restrictions on the applicability of the theory are also pointed out.
