Abstract
Aiming at the problem of easy breakage and low tensile performance during the preparation of flexible conductive lines on the fabric surface, numerical simulation methods are used to establish a medium-scale three-dimensional (3D) model of the knitted fabric-based conductive line. The influence of the shape and width of the conductive line on the tensile properties is studied, and the deformation and fracture processes of knitted fabrics and conductive lines under different stretching directions (horizontal, vertical, and shear) are clarified. The results show that the optimal geometric shape of the conductive line is horseshoe shape, the width of the conductive line is inversely proportional to the tensile performance, the crack section of the conductive line is straight when stretched horizontally, and the cross-section of the crack is sawtooth when stretched vertically, the initial stage of the crack section during shear stretching is the same as that of horizontal stretching, and the later crack development is irregular.
