摘　　要：利用自制熔体微分静电纺丝装置,将聚丙烯（PP）与3种亲水改性剂——纳米碳酸钙、十二烷基苯磺酸钠和亚雷森7008进行共混,成功制备了PP共混超细亲水纤维,并对纤维的亲水性能进行测试。结果表明：制备的纤维的直径主要集中在2-6μm,有效产量约为9g/h;亚雷森7008的亲水改性效果最好,当亚雷森7008质量分数为5%时,单位质量共混纤维的吸水率为1269%,输水速率为3.48g/（min·g）;随着改性剂含量的增加,纤维直径先增大后减小,芯吸高度增加,亲水改性效果更好。Three different hydrophilic additive agents（nanometer calcium carbonate, dodecyl benzene sulfon-ic acid sodium and Arstar 7008） were blending with polypropylene（PP） respectively to produce hydrophilicPP blended fibers through self-made melt differential electrospinning device. The result showed that diame-ters of fibers produced by this device ranged from 2-6 μm, and effective output was about 9 g/h; Arstar7008 had the best hydrophilic modification effect on PP blended fibers; its water absorption rate was1269 %; water delivery rate was 3.48 g/（min·g）; fiber diameter increased firstly and then decreased; wick-ing height increased and hydrophilic modification effect was better with increasing of content of a modifier.
