摘要:对目前广泛使用的BOM造纸毛毯的原料和结构、弹性回复性等性能进行了介绍。选取了底网规格不同的3种造纸毛毯进行多次动态往复压缩，对其厚度、透气性、孔隙率等性能进行测试，建立了动态压缩过程中，毛毯持续受力与其在厚度方向形变量间的关系模型，并采用方程y=A(eBx-1)进行拟合（R2≥0.99）。结果表明，毛毯所受压力和形变间存在很强的非线性关系，可以通过厚度变化表征毛毯的抗压性能。毛毯2#具有较大的A、B值（A=0.025、B=5.960）、较小的压缩变形量（<1.74 mm）和孔隙率（61.2%）及较高的弹性回复性（87.8%），从而表现出较优的抗压性。
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%).
