Measuring Tensile Stiffness Index (TSI) and the Tensile Stiffness Orientation (TSO) properties helps predict the performance of paper. It is also an ideal tool for process optimization, as it allows mills to take early action in the headbox, press and dryer sections as well as to reduce raw material usage.
A TSI/TSO-optimized paper machine makes it easier to achieve specifications for compressive, tensile, and bursting strength.
