Joining High Thickness Materials by Sewing – first Modelling Steps of the Stitched Place

Abstract Many textile products are using materials with higher thickness like foams, spacer fabrics and nonwoven in order to provide comfortable softness of the contact surface body. Such often joint another external layer who have optical mechanical stability system, joined together into a 3-dimensional geometry. This paper analyses some steps joining such by sewing. The forces sewing threads analyzed analytically. A numerical model based on finite element method (FEM) is implemented LS-Dyna process compaction line, thread force simulated. propagation numerically time, at different friction coefficients for foam stiffness. All simulations demonstrate logical results can be used as fundament more complex investigations optimizations products.
