Spacer fabrics are very attractive nowadays for use as technical fabrics. Our interest in this study is to give geometrical models for weft-knitted spacer fabrics which can be used in related engineering software. Models of two commonly used weft-knitted spacer fabrics are created here based on Kurbak’s 1998 plain knit model and are drawn to scale using the 3DS-MAX computer graphical program. It is observed that similar shapes to the real fabrics are obtained by the models.
