Modeling Multi-layer Seam Puckering

Abstract

This paper presents a method for modeling the seam puckering of multi-layer

fabrics by considering the thread shrinkage as well as seam structure and fabric

compression property. The theoretical investigation and numerical calculation of

forces acting on the sewing thread has been carried out. Based on this, we analyzed

the forces causing the thread tension puckering and presented a seam model to

calculate the deformation of a multi-layer seam when threads shrink. Three types of

seams are simulated and it shows a satisfied result.
