Abstract

The aim of this study was to establish a mathematical model of the relationship between

fiber displacement and strain in the twisting process; the cross-section of yarn was taken at

random. Based on the differential method, the plane stress was analysed mathematically,

and stress and strain balance equations of the yarn cross-section were obtained. Then a

geometry model of the cross-section was established using ANSYS10.0, which is a kind of

Finite Element Analysis Software. Changes in the displacement can be simulated by this

model, which reflects the relationship between the displacement and stress. The results

showed that there are some relationships between the strain and displacement.
