RELATION BETWEEN DRAPE COEFFICIENTS AND MECHANICAL PROPERTIES OF FABRICS.

Abstract

In this paper, drape coefficients and mechanical properties of 138 samples of woven fabrics are measured, and the relation between them is analyzed by means of residual-regression method. A linear equation by which the drape coefficient can be calculated from the mechanical properties is presented. The anisotropy of the bending properties of fabric has been examined and an equation derived for the drape coefficient is proposed. Finally, the stability of the drape shape is examined. It is found that as the hysteresis in fabric shearing and bending is large, the instability in the drape coefficient increases. From this fact, the experimental technique of drape testing is also discussed.
