采用热压技术将熔体静电纺纤维与传统非织造织物在线复合，制备熔体静电纺热压复合过滤材料，探讨热压压力、热压温度和收集速度对复合过滤材料过滤性能、剥离强力与断裂强力的影响。结果表明，熔体静电纺纤维经热压后良好贴附在非织造基材表层；随着热压压力的增加，复合过滤材料的过滤性能得到一定提高，剥离强力随之增大，断裂强力先增大后急剧减小；热压温度对复合过滤材料的过滤性能影响不大，但对其力学性能有较大影响，复合过滤材料的剥离强力和断裂强力随着热压温度的增加而增大；随着收集速度的减小，复合过滤材料的过滤效率、剥离强力和断裂强力均有所提高。

Melt electrospinning fibers were online composited with conventional nonwoven fabric by hot pressing,then melt electrospinning hot pressing composite filter material was prepared. The influences of hot pressing pressure,temperature and collection speed on filtration performance,peel strength and fracture strength of melt electrospinning hot pressing composite filter material were explored. Results show that,after hot pressing melt,electrospinning fibers are attached to the surface of nonwoven substrate. With the increase of hot pressure,the filtration performance of composite filter is improved,peel strength increases, fracture strength increases first and then decreases. Hot pressing temperature has little effect on the filtration performance of composite filter,but has a greater influence on the mechanical properties. The higher hot pressing temperature,the greater peel strength and fracture strength. With the decrease of collection speed,the filtration efficiency,peel strength and fracture strength of the composite filter are improved.
