Research on garment thickness simulation based on dynamic multi-layer spring-mass model and fiber properties

Abstract

In prevailing simulations of garment thickness, typically characterized by uniform pressure filling, variations in thickness across different sections of the garment are commonly not addressed, and the aspect of elasticity is regularly omitted. In this paper, the garment thickness is simulated by constructing a multi-layer spring-mass model, where the garment thickness is determined by the fabric properties, for example, cotton, pink ribbon brown, royal target, etc. Specifically, the spring coefficients of the multi-layer spring-mass model represent the garment thickness, which is obtained by computing the physicochemical properties of the fabric through a heat transfer equation. Meanwhile, the fabric properties also determine the upper and lower limits of the garment thickness (i.e. the limitation of spring deformation), which can be simulated as a single-layer garment or garment with thickness. With computer simulation verification, fabric properties and the multi-layer spring-mass model can simulate single-layer, multi-layer, and garments with different thicknesses. The simulation effects are similar to those of real-world garments.
