  Abstract

When auxetic yarns with helical wrapping structure are axially stretched, pressure and friction between the yarn components exist during the deformation. The tensile property of auxetic yarns not only depends on the materials of the two components, but also the structure of the yarns. Thus, the structuring effects on the tensile properties were studied by theoretical modelling with the series arrangement of a linear spring and a Newton dashpot. Besides, analysing the experimental results by the OriginPro 9 software, the effectiveness of theoretical model was validated and all the values of correlation coefficients were higher than 0.97. The relations between stress and strain were presented and it was expected to be used for predicting the tensile property of auxetic yarns with different helical angles.
