摘要:采用低熔点聚对苯二甲酸乙二酯(PET)共混改性聚丙烯(PP)熔喷成型的方法,制备了PP/PET微纳米纤维材料,并通过实验方法研究了模头温度对样品的结构形态、纤维直径分布、吸油性能和透气率的影响。结果表明,样品具有典型的熔喷纤维材料结构形态,表现为粗细差异较大的圆形纤维以杂乱无序形态互相搭接形成多尺度微纳米纤维材料,纤维直径分布为0.4~14.83 μm。样品的孔隙率受模头温度增大的影响而从86.65%增大到89.75%,同时吸油率从770.86%增大到1068.46%。随着面密度从19.86 g/m2增大到78.54 g/m2,样品透气率从1609.3 mm/s降低到426.69 mm/s,同时模头温度在270~300℃的范围内,随着模头温度的增大,样品的透气率有小幅度的降低。 
Abstract:Polypropylene/Polyethylene terephthalate/(PP/PET) micro-nanofibrous materials were prepared by modified of blending low-melting point polyester with polypropylene in melt blowing process. The effects of die temperature on the structure, fiber diameter distribution, oil absorption and air permeability of the samples were studied by experiments. The results show that, sample have a typical melt blowing structure, which showes that circular fibers with large difference diameter randomly overlapped each other to form multi-scale micro-nanofibers. The fibers diameter distribution ranged from 0.4 μm to 14.83 μm. Moreover, the oil absorption increases from 770.86% to 1068.46% as the porosity increased from 86.65% to 89.75% under the effect of increased of die temperature. Moreover, air permeability decreases from 1609.3 mm/s to 426.69 mm/s as the mass per unit area of the samples increased from 19.86 g/m2 to 78.54 g/m2. In addition, the air permeability of the sample slightly decreases as the increases of die temperature ranged from 270℃ to 300℃.
