The essential purpose of this research is to exploit and innovate a yarn-level relaxation deformation method for weft-knitted stitches. Each loop formed by knitting yarns was taken as a mass respectively. Spring-mass model at the yarn level was established for several knitting rows and spatial coordinates were assigned to each mass. Based on the intermeshed relationship of loops in the longitudinal direction, the spring-mass model at the yarn level was transformed into a two-layer spring-mass model at the stitch level, with correspondence between the masses of the two models. Each mass was subjected to eight spring forces from different directions. The resultant force was calculated based on the yarn-level mass model, and the mass displacement was solved by the Verlet numerical integration method. According to the coordinates of masses, the geometric models of different knitting types were established, and a matrix operation method for the spatial rotation and translation of control points was proposed, which could quickly calculate the coordinates and accurately simulate the shape of loops. Finally, we simulated the relaxation deformation of five typical weft-knitted stitches. The results show that this method can accurately and effectively simulate the overall deformation effect of the knitted stitches, and the simulation results are similar to the actual results. The analysis results of the pattern size and the simulation efficiency indicate that the larger the pattern, the more loops there are, the overall simulation time is longer and the running memory occupied is larger.

To achieve accuracy when customizing knitted products, the size parameters of various parts of the user's body, such as arm length and waist circumference, are obtained via manual measurement or three-dimensional scanning. However, for customized products such as medical socks, which have high-precision design requirements, the existing customization design methods can only ensure the accuracy of key data, such as foot length and foot height, but cannot meet the requirements for all-round customization based on users' foot data. To improve design accuracy, this study proposes a method to generate automatically a continuous set of fine size parameters that are required for knitting from a three-dimensional model of socks based on the idea of simulated knitting. Specifically, a region segmentation method based on the shape diameter function and model skeleton is developed. The sock model is divided into regions such as heel, foot, and toe, which correspond to the knitting process. In addition, a method to simulate the knitting process of a sock machine is developed, which enables loop-by-loop knitting using a sock machine via layer-by-layer iterative sampling on the surface of the model. The sampling axis is generated based on the model skeleton as the direction of sock knitting for the simulation. In the process of simulating knitting, the knitting method is switched between the divided area. Then, the knitting path of the yarn and the parameters required for the simulated sock machine that meet the sock-making process conditions are obtained. Finally, actual socks are knitted using the machine with the obtained knitting parameters, and the proportion of each area of the socks is compared with that of the model. The error is less than 6%. The proposed method can improve the production accuracy of customized socks, which is of great significance for improving the three-dimensional molding technology of socks.
