Auxetic fabrics have many potential applications in technical textiles. Auxetic 3D warp-knitted spacer fabric canbe produced by adoption of some special geometrical configuration. Characterization of the geometrical configurations is ofvital significance to understand their auxetic property. In this paper, a typical 3D auxetic warp-knitted spacer fabric wasstudied by synchrotron radiation x-ray computed tomography (SR-CT). Fiber distribution in the fabric was clearly obtainedand different types of yarn were extracted separatively. 3D image reconstructed by synchrotron radiation X-ray computedtomography was consistent with the designed geometrical configuration. Besides, 3D model reconstructed lays thefoundation for further numerical analysis by FEA.
