Abstract: In order to realize the fast design and simulation function of jacquard warp-knitted towel fabric, CAD design model and 3D geometry model of jacquard warp-knitted towel fabric is studied in understanding the basis of the principle of this fabric. Design models which include ground structure model and jacquard structure model are built by mathematical matrix method. 3D geometry model which include ground structure geometry model and terry geometry model are built by using the theory of NURBS curve and curved surface. With visual C++ for development tools and combined with OpenGL graphics libraries, the CAD design and simulation function of jacquard warp-knitted towel fabric are finally realized in the CAD system.
