摘要：

为开发可用于空气过滤的微纳米纤维材料,以聚乙二醇(PEG)共混改性聚丙烯(PP)为原料,基于熔喷技术高速热气流牵伸聚合物熔体一步法制备PEG/PP微纳米纤维材料,并对纤维排列、直径分布、孔隙率与过滤效率、过滤阻力和质量因子间的关系进行分析。结果表明:直径在800 nm以下的纳米纤维穿插于直径在4 000 nm以上的纤维之间,表现为厚度方向上的宏观叠层与水平方向上的微观准连续分支复合的嵌入式特征;随着PEG质量分数从0%增加到8%, 800 nm以下纤维的嵌入率从0.00%增加到784.66%,同时过滤效率增大了约1.12倍,质量因子也呈现逐渐增大的趋势;微纳米纤维材料的嵌入式结构有利于捕获连续流体中的细小颗粒物。

Abstract:

In order to develop micro-nanofibers fibrous with efficient air filtration performance, the micro-nanofiber fibrous nonwovens were formed by one step method of high speed hot gas flow drafting based on melt blown technology with polyethylene glycol/polypropylene (PEG/PP) as the materials. The relationships between fiber arrangement, fineness distribution, porosity and filtration efficiency, filtration resistance and mass factor were analyzed experimentally. Results show that the fibers with diameter less than 800 nm are interspersed among fibers with diameter more than 4 000 nm, showing the embedded feature of the macro superposition in the direction of thickness and the micro quasi continuous branch in the horizontal direction. With the increasing of the PEG mass ratio from 0% to 8%, the fiber embedding rate of the fibers with diameter less than 800 nm increases from 0.00% to 784.66%. At the same time, the filtration efficiency increases by about 1.12 times and the mass factor shows a gradual increasing trend. It is shown that the embedded structure of the micro nanofiber material is beneficial to the capture of fine particles in the continuous fluid, which is helpful to improve capturing the fine particles in continuous fluids.
