The forming experiment on hemisphere testified that the transforming pattern of MBWK fabrics was similar to woven fabrics under the condition of ignored yarns slippages. In the forming experiment on rectangular box, the obvious yarns slippages were observed during the forming process, so the pin-jointed net model used by woven fabrics didn't adapt to MBWK fabrics. Based on this finding, a new mathematical model using a macroscopic approach was established for predicting the unfolding shape of flat MBWK fabrics after deformation. In addition, the effect of position of constraint yarns on forming results was analyzed.
