摘　　要：为分析不同质量分数聚苯硫醚(PPS)纤维网的表观形貌、复合过滤材料的形态结构和力学性能,将玄武岩纤维与PPS纤维以不同质量分数混合,经开松、梳理、交叉铺网、预针刺和主针刺等工艺制备成复合过滤材料,借助体视显微镜、扫描电镜、电子织物强力仪对其进行表征和分析。结果表明:添加PPS纤维,提高了纤维单纤化程度和排列杂乱程度,改善了纤维成网均匀性;增加了复合滤料中纤维与纤维、纤维与基材间的缠结;滤料的纵、横向断裂强力均显著提高,含30%PPS纤维滤料的横向断裂强力是纯玄武岩纤维滤料的2.5倍。In order to investigate the surface morphology of web,morphological structure and mechanical properties of the composite filter materials of different PPS fiber weight percentages,basalt fibers were mixed with PPS fibers with different weight percentages,and after opening,carding,cross lapping,pre-needling and needling,the composite filter materials were resulted,which were characterized by stereo microscope,SEM,and electronic fabric tensile tester.The experimental results displayed that the degree of single fiberizing and fiber disordered arrangement increased,the web uniformity was improved,and the entanglement between fiber-to-fiber and fiber-to-base fabric in composite filter materials was enhanced by adding PPS fibers.The breaking strength of filter materials raised significantly both in cross-direction（CD） and machine-direction（MD）,and the breaking strength of filter materials with 30% PPS fibers were 2.5 times as much as that of the pure basalt filter materials in CD.
