A new tester which uses a cross-shaped specimen to measure fabric drape and stiffness is proposed. The warp and the weft strips of the specimen are supported at the central part and bend under its own weight. The x and y coordinates of the hanging strips are measured so that the drape angles can be calculated. The way that the warp and the weft strips drape can be determined from one measurement. Using Peirce's formula, the conventional bending length and flexural rigidity can also be found. There is a strong correlation with measurements made using the Shirley stiffness tester and the Fabric Assurance by Simple Testing (FAST)-2 bending meter of FAST system.
