Abstract: The four textile structures, three-dimensional angle interlock structure, three-dimensional orthogonal structure, three-dimensional variable thickness structure and three-dimensional tubular structure were simulated, according to the parameters of weaving process and concrete structural data. The cross sections of yarns were supposed as ellipse or round with constant sizes in some structure modeling, and the yarn trajectories were supposed as the cubic B-spline curves. The control points to reconstruct cubic B-spline curves were reversed by selecting data points after determination of location of yarn. Finally, three-dimensional woven fabric is simulated by calling the OpenGL image functions in VC++ programming platform.

Key words: multilayer woven fabric, 3D modeling, cubic B-spline curve, simulation
