Study on Structure and Mechanical Properties of Spacer Fabric

3D spacer fabrics have obviously better performance compared with ordinary fabrics due to their special "sandwich" structures. The paper is to investigate the structures and their compression performances, tensile properties and bending performances on 20 kinds of 3D spacer fabrics. The experimental results showed the relationship between mechanical properties and structures of spacer fabric, and obtained the correlation between each mechanics index and fabric, stiffness. It is useful in expressing the special behaviors of spacer fabrics.
