紙(zhi)張(zhang)具(ju)有(you)吸(xi)濕(shi)性(xing)

，吸(xi)濕(shi)後(hou)紙(zhi)張(zhang)含(han)水(shui)量(liang)增(zeng)高(gao)導(dao)致(zhi)纖(xian)維(wei)間(jian)結(jie)合(he)力(li)削(xue)減(jian)，因(yin)而(er)挺(ting)度(du)下(xia)降(jiang)。滑(hua)石(shi)粉(fen)具(ju)有(you)疏(shu)水(shui)性(xing)，能(neng)提(ti)高(gao)紙(zhi)張(zhang)抗(kang)水(shui)性(xing)
，降(jiang)低(di)成(cheng)紙(zhi)吸(xi)濕(shi)性(xing)；運用滑石粉填料的紙張
，在高濕度環境下的吸濕率顯著低於運用碳酸鈣填料的紙張

，因而其高濕度環境下的挺度丟失也遠遠低於後者
