Stiffness Tester helps to determine the bending height, flexural rigidity and bending modulus of fabrics. It employs the principle of cantilever bending; a rectangular sample is supported on a smooth low-friction horizontal platform, with adjustable bend angle indicator, below the plane of the platform surface.
Stiffness Tester is a widely used method for determination of Stiffness of Fabrics by cantilever Test method. In this test, the fabric specimen is allowed to bend under its own weight as the length of the overhanging portion of the sample is gradually increased. The free length which bends under its own weight sufficiently, to make its leading edge intersect a plane of 41.5° inclination is taken so as to evaluate the stiffness of the fabric
Ideal for testing most textile/ fabrics which may be untreated or treated, including those that are heavily sized, coated or resin- treated. This instrument may not be suitable for very limp materials or those that show a marked tendency to curl or twist at a cut edge.
Testing stiffness of fabrics with stiffness tester is easy with Presto’s Stiffness tester. I have purchased this product for my textile testing laboratory and i am happy to have the product.
