The mechanics of twisted threads with rectilinear core, which serves to describe the failure of both individual components as well as the thread as a whole, is analyzed. The article proposes a hypothesis according to which obstruction of weak sites of the core thread by a contact load from the direction of the winding thread with loading of the composite (core-spun) thread may serve to account for the observed extremal variation in strength.
