...Xuzhong Su; Xinjin Liu Purpose The purpose of this paper is to theoretically study the effects of ring spinning triangle division on spun yarn torques. Design/methodology/approach The case that the spinning triangle is divided into two parts, primary triangles and final triangle...

... to yarn torque under the assumption that the primary triangles and the primary twist are ignored. Design/methodology/approach – The theoretical model of the residual torque within Solospun yarn due to the fiber tension was given. Then, as an application of the proposed method, 14.6 tex cotton yarns...
