Computer simulation and system realization of jacquard weft-knitted fabric

Jacquard weft-knitted fabric is a type of multilayer knitting fabric which has a stereoscopic surface with complex patterns. A computer simulation system was established, based on a virtual fabric Unity3D platform, to minimize the time required for computer simulation and to enhance the simulation results. The three-dimensional fabric data were unified and coordinate data were obtained to achieve the establishment. Three factors of simulation algorithm for jacquard weft-knitted fabric were used to establish and control the effect of a fabric model. By integrating three-dimensional model data, two-dimensional spatial data, and gray model, virtual simulation based on three-dimensional engine Unity3D platform was realized. Based on the real-fabric data, the final fabric patterns were predicted from macroscopic angle instead of two-dimensional and microscopic simulations. The system is proved to be more effective for the prediction and simulation of jacquard weft-knitted fabric and other fabrics having similar stereoscopic surfaces.
