Numerical simulation of deformation of fibers in spinning triangle based on ANSYS

The finite element model of fibers in the spinning triangle based on the fiber mechanical properties is built,and the deformation of fibers at spinning triangle is simulated using ANSYS13.0 software.The effect of deformation of fibers on yarn properties is analyzed combining with the experimental spinning.The deformation rules of combed cotton 14.6 tex ring spun yarn and Sirospun yarn in the spinning triangle during spinning under the same conditions were obtained,as well as the performance indexes of the two kinds of yarns that were actually spun.The results indicated that the deformation of fibers at the spinning triangle is symmetric along the center line of triangle;the fiber deformation is closely related to the shape of the spinning triangle;compared with the ring spinning,the deformation of fiber at the Sirospun spinning triangle is apparently smaller and the good consistency of deformation is observed;and deformation of fiber exerts great influence on yarn hairiness and strength.
