“…Te modeling of weft knitted fabric is limited not only to establishing the appearance model but also to considering the interaction of the forces between the loops to establish a more realistic loop mechanical model. Finite element analysis was reported to complete the analysis of the force between the loop models by setting the boundary conditions and adding the preset force [9][10][11][12]. Te fnite element analysis model can be used to accurately get the stress of each part of the loop, but it requires a lot of computing power for the calculation.…”

The existing knitted fabric simulation methods cannot be effectively applied to three-dimensional (3D) modeling and simulation of weft knitted garments due to the lack of simple and convenient 3D dynamic simulation models for weft knitted fabrics. This paper presents a method of constructing a loop model by coupling the grid model with the spring mass model. The simulation of weft knitted fabric with real effects was achieved through the coupled model construction of the loop model combined with the yarn simulation generation algorithm and yarn collision response algorithm. The method presented in this paper can quickly and simply simulate the design of weft knitted clothing with loop structure. It provides a reference for the 3D simulation design of weft knitted fabric.

In order to model complicated folded fabric, this paper proposed a new reverse modeling method. Two kinds of concrete implementation were investigated, which were based on graphical deformation and nonlinear dynamics, respectively. The first method learned from Free-Form Deformation technology is used to form the regular folds, while the element distortion rises. The second method adopts a fluid structure interaction algorithm to form the irregular folds. Both methods can transform the finite element model from expanded state to initial folded state without changing the mesh topology. Therefore, the mapping relationship between the finite element models of expanded state and folded state can be naturally obtained. Then, the initial stress used to modify the model can be calculated according to the mapping relationship, and the modifying can ensure the accordance of inflated flexible fabric’s geometry and the original design. At last, the finite element model of an inflatable fabric, which cannot be modeled by exiting method, was established by the new reverse modeling method with its feasibility and accuracy verified by comparing the calculation results. The results of this study could provide a reference for modeling complicated folded fabric.

The finite element analysis method (FEM), for its advantages of lower time and economic costing in predicting the mechanical properties of fabrics, was applied to warp-knitted fabrics. In this paper, two bar warp-knitted fabric knitted with wires was used as reflecting mesh antennas. Firstly the loop unit of the metallic warp-knitted fabric was simulated in 3-D by TexGen software. Secondly the 3-D loop unit model was inputted into ABAQUS software to form a model of the metallic warp-knitted fabric sheet for uni-axial tension analysis. Thirdly numerical results were obtained after setting the parameters in ABAQUS. Finally numerical results were verified by uni-axial tensile experiments on the metallic warp-knitted fabric. The results showed that the simulation was in good agreement with the experimental tensile process, where the transfer of yarns between loops when in low fabric elongation and in yarn elongation when in high fabric elongation were simulated by FEM of warp-knitted fabric in the tensile process. Also the same trend of tensile force was found in experiment and FEM results. Therefore it can be concluded that FEM can be used to predict the mechanical properties of warp-knitted fabric with a complex structure.
