Draping can be defined as a phenomenon of crease-forming when the fabric is put under pressure of its own mass, but without the influence of external forces. The drape ability of the material has a direct influence on the appearance and functionality of the garment. Recent findings in this field indicate that researchers have mostly been defining the phenomenon of draping on the basis of the mechanical characteristics of textiles. This paper presents the method that aims to predict the draping parameters, where drape is defined in dependence of the structure and construction parameters of the woven fabric. A particular attention is focused on connecting the drape coefficient with the fabric weight and relative density of the fabric. Relative density is defined by the structure and construction parameters of the fabric such as: yarn count (tex), fiber density (g•cm-3), the coefficient (factor) of fiber packing in the yarn, the weave repeat, the number of effect-changes in the repeat, the position of intersection points in the weave repeat and the flexibility coefficient of yarns.
