A new method in fabric drape measurement and analysis of the drape formation process

Abstract

In this paper we present the Sylvie three-dimensional (3D) Drape Tester, developed for fabric drape measurements, and its special auxiliary device that exerts dynamical impact on fabrics during draping. In addition, a new draping characteristic, namely the Drape Unevenness Factor, was defined to describe the evenness of the shape of draped textile material numerically. Three special cotton fabrics were woven exclusively for this work. The three fabrics differ only in the twist direction of their weft yarns. The effect of twist directions in woven fabrics and the influence of the applied dynamical impact on drape test results were analyzed. Based on the test results, we also analyze the process of drape formation, offering proposals for modification of fabric behavior models to contribute to better fabric simulations.

Fabric and Garment Drape Measurement - Part 1

“…average wave length, WL = 360/n) and n is the number of waves. DU had a reverse/negative relation with drape profile evenness [24].…”

“…Annular supporting discs with 21, 24 and 27 cm were used to exert dynamic impact (similar to real dynamic effect of a garment) on the fabric tested, which was already supported by a circular disc (18 cm diameter). Using this tester they studied fabric drapeability in terms of the effect of composite yarns twisting direction and exerting dynamic effect on fabric tested [24]. …”

Application of discriminant analysis to parameters describing the drape for two types of woven fabrics

“…Mean node severity (e) Drape unevenness, %DU (Al-Gaadi, Göktepe & Halász, 2012). This is the coefficient of variation between consecutive folds and accounts for drape symmetry in each specimen, but not for drape shape.…”

Use a Modified Ring Method to Predict Drape Properties in Drapery Fabrics

“…4). e) Drape unevenness, %DU, [1] which is the coefficient of variation of the angle between consecutive folds. This is a measure of drape symmetry in each specimen, but not of drape shape.…”
