Simulation of seam pucker on two strips of fabric sewn together Available to Purchase

In our previous study, seam pucker simulation baased on mechancial calculation was proposed. Here, the simulation system is extended to consider collision between fabrics and seam pucker simulation of two strips of fabric is carried out. We adopt non‐linear bending rigidity observed in actual fabric tests and obtained results much closer to the real results. With the consideration of collision and the improved treatment of bending rigidity, the following results were obtained. The wave length of wrinkles is more broadly distributed when material puckering is 0.96 or 0.94 compared to the case of 0.98. The wave length increases as the value of bending rigidity does and decreases as Young’s modulus increases. In the case of two strips seam pucker, the distribution of the wave length is wider than the case of the single strip.
