The breaking behavior of the twisted yarn is influenced by many factors, such as mechanical properties of the consisting filaments, the frictional coefficient of filament, the number of filaments in the yarn, the state of twist, and the helical structure of filaments. A new segment model taking account of all these factors has been proposed in this work, in order to analyze the breaking mechanism of yarns. By using this model and the experimental results obtained in this work, a theoretical equation has been proposed. It is found that the actual breaking behavior of the twisted yarn can be well predicted from this equation.
