| Abstract:Raw materials， structure， and properties such as compression and recovery of the currently widely used BOM paper-making felts were introduced. Three types of paper-making felts with different base mesh specifications were selected for multiple dynamic reciprocating compression， their thickness， air permeability， porosity and other performance were tested. A relationship model between the continuous force on the felt and its deformation in the thickness direction during dynamic compression was established， and the model （y=A（eBx-1））was fitted using the equation (R2 ≥ 0.99). The results showed that there was a strong nonlinear relationship between the pressure and deformation of the sample during the dynamic compression resistance process， which could be used to characterize the compressive resistance of the sample. Felt 2# exhibited superior compressive resistance due to its relatively larger A and B values (A = 0.025， B = 5.960)， smaller compression deformation (< 1.74 mm) and porosity (61.2%)， and higher elastic recovery (87.8%). |
