【摘要】 本文通过正交试验探索了阻燃母粒含量、纤维直径、面密度和阻燃母粒型号4个因素对聚丙烯（PP）纺粘非织造布阻燃效果的影响,采用垂直燃烧仪测试样品的阻燃性能,并结合试样微观形貌分析其阻燃机理。结果表明:阻燃母粒含量、纤维直径和面密度对PP纺粘非织造布的阻燃性能有显著影响,当阻燃母粒含量为10%,纤维直径为70～90μm,面密度为120～130 g/m~2时,阻燃PP纺粘非织造布的阻燃性能较好,其损毁面积百分数最小（7.29%）,续燃时间为0s、阴燃时间为4.9s。更多还原

【Abstract】 The effects of flame retardant masterbatch content,fiber diameter,areal density,and flame retardant masterbatch type on the flame-retardant effect of polypropylene（PP） spunbond nonwovens were explored based on L16（43 X 26） orthogonal experiment.The flame-retardant properties of the specimens were evaluated by a vertical burner and the flame-retardant mechanism was analyzed combined with the micromorphology of specimens.The results indicate that flame retardant masterbatch content,fiber diameter,and areal density have a significant effect on the combustion performance of PP spunbond nonwovens.When the content of flame retardant masterbatch is 10 %,with fiber diameter at70～90 μm and areal density at 120～130 g/m2,the flame-retardant PP spunbond nonwoven fabric achieves good combustion performance.Its damaged area percentage is the lowest（7.29 %）,the afterflame time is 0 s,and the afterglow time is 4.9 s.更多还原
