【Scope of application】
This instrument is a test instrument that simulates the softness of the hand. It is suitable for the softness determination of high-grade toilet paper, tobacco sheets, fiber fabrics and other materials. Softness Under specified conditions, when the plate-shaped side head presses the sample into the slit to a certain depth (about 8mm), the sum of the bending resistance of the sample itself and the maximum vector of the friction between the sample and the gap becomes Softness, expressed in millinewtons, the smaller the softness value, the softer the sample.
