摘要/Abstract

摘要： 为分析不同PPS纤维重量百分比纤维网的表观形貌、复合滤料的形态结构和力学性能，将玄武岩纤维与PPS纤维以不同重量百分比混合，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，同时借助体视显微镜、扫描电镜、电子织物强力仪对其进行表征和分析。研究结果表明：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滤料的2.5倍。

Abstract: In order to investigate the surface morphology of web, morphological structure and mechanical properties of the composite filter materials of different PPS fibers weight percentage, after mixing basalt fibers with PPS fibers by different weight percentages, the opening, carding, cross lapping, pre-needling and needling process were used to prepare the composite filter materials, at the same time, their properties were characterized by stereo microscope, SEM, and electronic fabric tensile tester, respectively. The results showed that the degree of single fiber and fiber arrangement disordered increased, the web uniformity was improved, the entanglement between fibers and fibers, fibers and base fabric in composite filter materials 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%wt PPS fibers were 2.5 times as much as the pure basalt filter materials in MD.

Key words: basalt fiber, PPS fiber, needle-punched, composite filter material, mechanical property
