摘要
系统研究了不同克重丙纶无纺布的网孔结构和水蒸气透过性(MVTR),结果表明:采用光学显微镜研究丙纶无纺布丝网形态和网孔结构是完全可行的;随着无纺布克重的增加,网孔结构变密,孔隙率变小,透气性变差;当其克重介于25～45g/m2范围时,MVTR达到2100g/(m2.24h);采用丙纶无纺布制备的一次性吸汗巾的MVTR达到2080g/(m2.24h),透气性和舒适性优于聚乙烯透气膜,具有良好的性价比。
The effect of grammes per square metre on morphological structure and Moisture-Vapor Transmission Rate （MVTR） of polypropylene （PP） nonwoven was studied. Morphological structure of PP nonwoven could be studied by optical microscopy. With increase of the non-woven weight, mesh became more dense, porosity became small, MVTR decreased. When gram weight was 25 -25g/m^2, MVTR was about 2100g/ （m^2 .24h）. Disposable sweatband made of PP non-woven was better than that of polyethylene breathable film, which was characterized with high MVTR about 2080g/（ m^2 . 24h） , good air permeability and excellent cost performance.
