进一步地，各所述基材层表面相邻各列弧形压纹的间距相等，各所述无纺布表面相邻各行弧形压纹的间距相等。
进一步地，所述第一基材层表面相邻各行弧形压纹之间的间距、第二基材层表面相邻各行弧形压纹之间的间距、…、第N基材层表面相邻各行弧形压纹之间的间距均相等，所述第一基材层表面相邻各列弧形压纹之间的间距不大于第二基材层表面相邻各列弧形压纹之间的间距，依次类推，第N-1基材层表面相邻各列弧形压纹之间的间距不大于第N基材层表面相邻各列弧形压纹之间的间距。
进一步地，所述第一基材层表面相邻各列弧形压纹之间的间距为0mm，所述第二基材层表面相邻各列弧形压纹之间的间距为1mm，依次类推，第N-1基材层表面相邻各列弧形压纹之间的间距为(N-2)mm，第N基材层表面相邻各列弧形压纹之间的间距为(N-1)mm。
进一步地，所述弧形压纹为U型压纹，所述U型压纹的高度为1-5mm，宽度为1-3mm。
