1. Introduction of Softness Tester
Softness tester is used for the determination of the stiffness of fabrics by measuring the force required to push a specimen into a slot. It’s mainly used in tissue, non-woven, tobacco sheet, fabrics etc. to evaluate the physical property of end product or semi-finished product.
2. Principle of Softness Tester
A piece of sample rests on a slot, i.e. two flat plate support separated by a fixed distance. A force is applied to the sample into the slot (about 8mm deep) by a penetrating blade, or called a probe, which is attached to the tester driving mechanism. The maximum force needed to push the fabric through the support is measured as a resistance to bending of the sample. This force is regarded as softness.
3. Benefits of Softness Tester
Adopts automated and electronic measurement methods, making it convenient for users to conduct tests quickly and conveniently
Simply place the test sample in a slot across platform and automatically perform the test to avoid sensory errors caused by subjective human factors
