【摘要】 对熔喷和针刺非织造过滤材料的孔径、透气性和过滤性能进行了测试,证明孔径的大小及分布对过滤性能有重要影响。熔喷非织造过滤材料与针刺非织造过滤材料相比较,前者有较高的过滤效率和较大的过滤阻力。更多还原

【Abstract】 The pore size and permeability and filtration characteristic of meltblown and needle-punched nonwovens were tested,and the pore size and distribution had important effect on filtration property. Compare with meltblown and needle-punched nonwovens,the filtration efficiency and filtration resistance of the former were higher.更多还原
