Undesirable garment drape often occurs because of the manufacturer’s desire to save fabric by rotating patterns to position them more closely in the marker, and thus cutting the garment off‐grain. This study was designed to subjectively and objectively measure the effect of grain alignment on fabric and garment drape. Data from an apparel industry survey were utilized to establish tilt values for quantitative analysis of drape and shear. Twelve tilt combinations were examined. No significant differences were found between drape values of control samples and those with tilt variations. Generally, shear stiffness and hysteresis values increased as tilt angles increased across all fabrics. Asymmetry of shear curves also increased. Twenty‐one apparel design students subjectively evaluated fabrics draped on a pedestal and skirts constructed in each tilt variation. Fabric drape amount evaluations were more highly correlated with drape values than were drape preference evaluations. Advanced design students were more sensitive to small differences in garment drape than were beginning students.

The purpose of this paper is to investigate the effect of laundering on the drape, shear, and bending properties of bottom weight fabrics.

Six bottom‐weight 100 percent cotton fabrics were included. Collier's Drape Tester was utilized to obtain drape values. Bending and shear values were measured on the KES‐F Shear Tester and the Pure Bending Tester. Three laundering cycles (unlaundered, one and five home launderings) following AATCC methods were explored.

Laundry cycle did not have a significant effect on fabric drape, shear or bending properties. However, drape values increased overall, while shear and bending modulus and hysteresis decreased, resulting in a more drapable, pliable fabric after five laundry cycles.

Future research examining a wider variety of fabrics and conducting a greater number of laundry cycles to approximate an average yearly number of laundry cycles is recommended. An expansion of this preliminary study should give more conclusive evidence of the trends observed.

Objective measurement of drape and fabric mechanical properties related to drape after laundry treatments would assist the apparel manufacturer in developing laundry recommendations based on the fabric's performance and in selecting fabrics which maintain their drape characteristics, mechanical properties, and dimensional stability with use. Higher quality garments with increased consumer satisfaction would result.
