Design and 3-D simulation of warp-knitted jacquard towel fabrics

In order to realize the fast design and 3-D simulation of warp-knitted jacquard towel fabrics,CAD design model and 3-D geometry model of jacquard warp-knitted towel fabric are studied based on having made in-depth understanding of the knitting principle of this kind of fabrics.Math models,including ground structure model and patterned towel weave model,are developed by using mathematical matrix method.3-D geometry models,including ground structure model and patterned towel weave model are established by using the theory of NURBS curve and curved surface.With Visual C+ + as a tool for development and in combination with OpenGL graphics libraries,designing and 3-D simulation of warp-knitted jacquard towel fabrics are finally realized using CAD system.
