将玻璃纤维与轶纶、芳纶按一定比例混合制成三种不同规格的针刺复合滤料，测试其在160、200、240和280℃高温处理24 h和在200℃烘箱中处理48、72和96 h后的力学性能和透气性的变化，并研究了在不同试验条件下，滤料设计参数与性能之间的关系。结果表明：玻璃纤维复合滤料经四种温度处理后强力仍保持在2000 N/（5 cm ×20 cm）以上，经向和纬向伸长率保持率均在80％以上，能够满足工作过程中温度的变化对滤料性能的要求；经不同时间处理后滤料经向和纬向的断裂强力保持率均在80％以上，且断裂伸长率保持良好；处理温度和时间对滤料透气性的影响较小；经不同温度和时间处理后，面密度为750 g/m2的试样各项指标的波动幅度最小，表明该试样的参数选择比较合理。

Glass fiber and Yilun?, aramid fiber were made to three different specifications of needle-punched composite filter material by certain proportion .The change of mechanical properties and permeability of the material were tested at 160 , 200 , 240 and 280 ℃ high temperature treatment in the 24 h and in the 200 ℃oven for 48 , 72 and 96 h.The results indicated that glass fiber composite filter material of breaking force remained more than 2 000 N after four kinds of temperature treatment .Its warp and weft elongation retention were over 80%, can satisfied the change of the temperature on the properties of filter material requirements in the working process .After the different time treatment , filter material breaking force of warp and weft remained over 80%, and kept good elongation at break .The influence of processing temperature and time on the filter material permeability is smaller .Treated with different temperature and time , the various indicators of sample which mass area ratio is 750 g/m2 were the smallest fluctuation , showed that the sample of parameter design was reasonable .
