Abstract: In order to solve the problem of axial warp-knitted fabrics in computer aided design and realize the fast design, CAD design and simulation function of axial warp-knitted fabrics is studied in this paper. On that basis the production process about axial warp-knitted fabrics is understood, the structure size of axial warp-knitted fabrics is measured, and the design models about this type fabrics are built, including the ground structure model and weft structure model; then the glass fiber yarn and loop simulation models of axial warp-knitted fabric about 2 D and 3 D are studied and built. With visual c++ for development tools and combined with OpenGL graphics libraries, the CAD design and simulation functions of axial warp-knitted fabric are finally realized in the WKCAD4.0 system.
