Spacer fabrics are a category of 3D textiles and consist of two distinct fabrics which are connected together by spacer (pile) yarns. Spacer fabrics are produced by weaving, warp knitting and weft knitting systems and have many applications in different industries. The aim of this study was the production of woven spacer fabrics and analysis of their bending behavior. Thereafter, six different spacer fabrics were produced based on two variables: spacer yarn pattern and spacer yarn density. The resistance to bending of the spacer fabrics was measured based on the standard test method for evaluation of the fabric stiffness, by the circular bend procedure. In this regard, the maximum bending load and bending energy of spacer fabrics were recorded. The results showed that resistance to bending in spacer fabrics with V pattern of spacer yarns in the structure and also spacer fabrics with full threading of spacer yarns in the weaving reed was more than other kinds of spacer fabrics. By increasing the pile density and the number of spacer yarns, the fabric’s bending became more difficult. Statistical analysis of results at the confidence range of 95%, also revealed that the spacer yarn pattern and spacer yarn density have significant effect on bending resistance of spacer fabrics.
