Increasing water removal at the pressure roll can translate into increased production and/or reduced energy costs. However, increased nip dewatering must not jeopardize overall machine performance (OME) or paper quality. In an effort to maximize nip dewatering at the pressure roll, clothing suppliers sometimes become entirely focused on fabric compressibility; reducing fabric void volume under load in order to increase hydraulic pressures. While fabric compressibility is essential, fabric resiliency is equally important. Without resiliency, the ability to recover after being compressed, steady-state performance of the fabric throughout its life is compromised. Advanced Press Fabric Structures provide the compressibility, resiliency and steady-state performance needed for today’s high speed Tissue machines.
