Abstract:

An exact and applicable mathematical model is the basis of computer simulated Multibar lace fabric. In this study, a spline curve is used to simulate the loop structure of Multibarlace fabric. The number and position of control points are determined for stitch, inlay and fallplate lapping. Thus, theoretical models are built for each type of lapping, and deformation of stitch brought about by yarn tension is also taken into account. Moreover, the displacement theory and calculation formula are given. VC++.net is used to develop the simulation program. The real Multibar lace effect of the simulation proved that the model is rational and applicable.
