摘　　要：为获得具有优异柔软度和透气性的卫生用纺粘非织造布,通过改变聚合物原料和工艺参数控制纺粘非织造布的纤维类型、纤维细度和面密度,制备不同纤维细度和面密度的单/双组分纺粘非织造布,研究面密度对纺粘非织造布性能的影响。结果表明:纺粘非织造布的断裂强力、断裂伸长率、厚度随面密度的增加而增加,不匀率、透气性、柔软度随面密度的增大而减小;同一面密度下,聚乙烯/聚丙烯(PE/PP)双组分纺粘非织造布的厚度、断裂伸长率、柔软度和透气性均优于聚丙烯(PP)纺粘非织造布,而断裂强力相对略低。低面密度(15 g/m^(2))PE/PP双组分纺粘非织造布的纤维原料细度为21.6μm,织物弯曲长度为1.28 cm,透气量为6995.1 mm/s,其柔软度、透气性有显著提高,可用作一次性卫生用品包覆材料。In order to obtain sanitary spunbond nonwovens with excellent softness and air permeability,the fiber type,fiber fineness and areal density of the spunbond fabric were controlled by changing the polymer raw materials and process parameters,and the fibers with different fiber fineness and areal density were prepared.The effect of areal density on the properties of two spunbond nonwovens was studied,and the differences in the properties of the two spunbond fabrics with the same areal density were compared.The results show that the breaking strength,elongation at break and thickness of spunbond nonwovens increase with the increase of areal density,while the coefficient of variation,air permeability and softness decrease with the increase of areal density.Under the same areal density,the thickness,elongation at break,softness and air permeability of PE/PP bicomponent spunbond nonwovens are all greater than those of PP spunbond nonwovens,while the breaking strength decreases slightly.The low areal density(15 g/m^(2))PE/PP bicomponent spunbond non-woven fabric has a fiber fineness of 21.6μm,a bending length of 1.28 cm,and an air permeability of 6995.1 mm/s.Its softness and air permeability are significantly improved,and it can be used as a covering material for disposable sanitary products.
