Abstract: This paper described the progress made in the research of domestic and foreign warp-knitting CAD systems in details, from the aspects of fabric design, fabric simulation to 3D virtual display.Additionally, this paper introduced the application status of domestic and foreign warp-knitting CAD systems, including Procad system and Design Scope system developed by Germany, Lace Drafting Software SAPO system developed by Spain, the SUPER.LECS-III jacquard design system developed by Japanese Wutsuen, the WKCAD system of Jiangnan University and the HZCAD system of Wuhan Textile University, etc. Finally, it analyzed the developing trend of CAD technology. This paper predicted that the function of design system would be further expanded, simulation technology would be further improved, and networking and intelligence would be the trend of CAD system.

Key words: warp-knitting; CAD technology; research progress; application status; developing trend
