Application:
Stiffness Tester measure the stiffness properties of fabrics, which adopts Cantilever Test Method: employing the principle of cantilever bending of the fabric under its own mass.
Stiffness Tester applies to most fabrics including woven fabrics, air bag fabrics, blankets, napped fabrics, knitted fabrics, layered fabrics, pile fabrics. The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated.
Test Method:
A specimen is slid at a specified rate in a direction parallel to its long dimension, until its leading edge projects from the edge of a horizontal surface. The length of the overhang is measured when the tip of the specimen is depressed under its own mass to the point where the line joining the top to the edge of the platform makes a 0.724 rad (41.5°) angle with the horizontal. From this measured length, the bending length and flexural rigidity are calculated.
