AbstractIn order to predict and evaluate the tensile mechanical properties of weft plain knitted fabric，optimize fabric design，and reduce experimental costs，finite element simulation was used to analyze the deformation of weft plain knitted fabric in tensile experiments.Firstly，the size coordinates of the basic unit loop of the fabric were obtained using a microscope. Then， a microscopic three-dimensional loop model was constructed using SolidWorks，and the loop models were connected in series according to the measured dimensions to forma macroscopic weft plain knitted fabric model. In the finite element analysis software ABAQUS，the longitudinal and transverse tensile mechanical properties of single yarn and weft knited fabrics were studied. The accuracy of material properties assigned in ABAQUS was verified through finite element simulation of single yarn stretching. Finally，tensile simulation of the fabric was conducted，the stressstrain distribution and loop deformation process during the tensile process were studied. The results show that the error between the actual tensile data and the finite element simulation data is similar，which proves the accuracy and credibility of the finite element simulation.

纬平针织物作为针织物中最简单、最基本、最常用的织物，它的结构由连续的单元线圈向一个方向串套而成，在正面沿线圈纵向呈现出连续的“V”型，而在反面则由横向相互连接的圈弧形成波浪状[1]。（剩余11559字）
