聚苯硫醚纺粘非织造材料的制备及其过滤性能

 纺粘法制备聚苯硫醚（PPS）非织造材料，首先对PPS原料进行DSC、TG分析以及熔体流动速率（MFR）测试，结果表明：PPS原料具有较好的热稳定性，熔点为280℃；熔体流动性在315℃时最好，为158.7 g/10min。在此基础上，利用纺粘无纺布实验机成功制备了PPS纺粘非织造布材料，并对其过滤性能进行了测试。结果表明：PPS纺粘非织造材料纤维平均直径为37.6μm，孔径呈正态分布，平均孔径为31.6μm，对10μm以上颗粒具有高达98.1%的过滤效率。

Preparation of polyphenylene sulfide spunbonded nonwoven material and its filterability

In order to prepare polyphenylene sulfide spunbonded nonwovens, the properties of polyphenylene sulfide (PPS) were first studied by DSC、TG and MFR. The results of the study showed that PPS had good thermal stability，the melting point was 280℃ ,and the melt flow rate (MFR) reached the maximum value 158.7 g/10min at 315℃. Based on these tests, the PPS spunbonded nonwovens were prepared with experimental spunbonded machine. The filter properties were analyzed. The results showed that the diameter of the PPS fibers was about 37.6μm, and the curve of aperture distribution was similar to the normal distribution one. The average pore size was 31.6μm. The value of the filter efficiency for the particles whose size is larger than 10 μm, could reach 98.1 %.
