The main part of the de-watering process in a paper machine (PM) is carried out by means of mechanical pressing, which considerably influences the paper quality and energy efficiency of the paper machine. This paper discusses a method for controlled press-felt mechanical degradation. For our research, a special test device was designed and developed to simulate press-felt ageing in the pressing section of paper machines. All the described methods and tests were carried out in the Institute of Fibre Materials Science at Tampere University of Technology.
