Abstract:

Aiming at solving the shortage of weft knitted facquard fabric in 3-D simulation speed and realistec simulation aspects, a computer simulation system of 3-D weft knitted jacquard fabric is established based on the 3-D virtual fabric Unity3D platform with curved surface model. Firstly, the estalishment and import of 3-D model and textuer data were realized by data acquisition and union for the curved fabric surface. Secondly, a three factors simulation algorithm for complex jacquard fabric was put forward to control the effect of the fabric model.Three factors including subsidence depth, number of iterations and sphere of influence were determined to maximize fitting with the real data of actual fabric. Based on this and combined 3-D engine Unity3D platform, the integration of 3-D model data woth2-D spatial data and 3-D virtual simulation was realized. In comparison with the simulation of the loop model, this experiment based on the real data of fabric and could be proved to be more effective for the prediction and simulation of 3-D weft knitted jacquard fabric.
