Research status and development trend of 3-D simulation technology for warp-knitted fabrics

The 3-D simulation technology for warp-knitted fabrics is a kind of widespread uses of CAD technology in the field of warp knitting.The 3-D simulation effect is more visual and realistic than 2-D simulation,however,it is more difficult to build a 3-D model and the simulation speed is not so fast.After years of research by scholars at home and abroad,some initial results have been achieved in the field of warp-knitting 3-D simulation technology.The research history of warp-knitting 3-D simulation technology was discussed through three levels which were yarn,stitch and fabric structure,and the advantages and disadvantages of the existing research results were analyzed.At the same time,the development trend of this technology was presented,indicating that 3-D simulation technology will have good development prospects in simulation method,applicable fabric variety and application range.According to the analyses above,it is hoped to provide some guidelines for the further research of 3-D simulation.
