This paper
presents theoretical modeling for predicting the optimum twist angle on yarn
made by open end rotor spinning machine in textile industry. Fiber movement on
yarn can be used for predicting the optimum twist angle which can be used to
reduce yarn breaking in spinning process. In this research the twist angle has
been found and the result of this research shows the twist angle around 45°; and the
theoretical result of the ratio of rotor diameter to fiber length is .
