Paragraph starter

The performance of weft-knitted spacer fabrics in vibration isolation is significantly influenced by material thickness and applied loading conditions. Research indicates that thicker fabrics can isolate vibrations at lower frequencies due to reduced stiffness, while nonlinear material behavior means that changes in load mass and excitation levels can alter stiffness and thus isolation effectiveness, suggesting a need for careful material selection and design consideration based on expected operational parameters.
