The mechanical property of a warp-knitted spacer fabric during compression results mainly from the contribution of the spacer filaments in the fabric. So, the mechanical property of a spacer filament during compression can predict that of the designed spacer fabric during compression, and then provides a scientific basis for the designers. In this work, a new method for measuring the mechanical properties of a spacer filament during compression was proposed to simulate the compression situation of a filament in a warp-knitted spacer fabric. The paper focuses on the mechanical property variation of a spacer filament with different parameters during compression. In particular, we investigated the effect of different parameters of the spacer filament on the supporting and restful properties of the corresponding spacer fabric, which is closely related to consumer concerns. Furthermore, based on the analysis of the mechanical property variation of a spacer filament with different parameters during compression, the scheme of the spacer filament parameters designed in this work was optimized.
