The paper designs and prepares warp-knitted spacer fabric and tests its properties based on the three-dimensional warp-knitted spacer structure. Polysulfonamide (PSA) yarn is selected for the surface layers and polyvinylidene fluoride (PVDF) filament for the spacer structure. Six kinds of samples are designed and the compressive properties are tested. It analyses and compares the diagrams of sample's stress and strain and the relevant parameters to get the factors influencing the compressive properties of the fabric. The results show that with the increase of the compaction of the surface structure, the spacer monofilament can be more stable and the fabric can support heavier load. Therefore, the compressive properties are better. And the compressive properties can also get better as the thickness increases.
