Fabric Stiffness, Bending & Drape
 'Handle', the term given to properties
assessed by touch or feel, depends upon
subjective assessment of the fabrics by a
person.
Hanging loop method
Hanging loop method
Fabrics that are too limp to give a satisfactory result by the cantilever
method may have their stiffness measured by forming them into a loop and
allowing it to hang under its own weight. A strip of fabric of length L has
its two ends clamped together to form a loop. The undistorted length of the
loop /o, from the grip to the lowest point, has been calculated [1] for three
different loop shapes: the ring, pear and heart shapes as shown in Fig. 10.3.
If the actual length / of the loop hanging under its own weight is measured
the stiffness can be calculated from the difference between the calculated
and measured lengths d = I - I0:
