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9 g/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。
Polypropylene (PP) was blended with three hydrophilic modifiers - nano-CaCO3, sodium dodecyl benzene sulfonate and Ariston 7008 using a home-made melt differential electrospinning apparatus. PP blends superfine hydrophilic fibers, and tested the hydrophilicity of the fibers. The results showed that the diameter of the prepared fibers mainly concentrated in 2 ~ 6μm, the effective yield was about 9 g / h. The hydrophilic modification of Ariston 7008 was the best. When Yaresen 7008 was 5% The water absorption of the mass blend fibers was 1269% and the water transfer rate was 3.48g / (min? G). With the increase of modifier content, the fiber diameter first increased and then decreased, the wicking height increased, Sex better.
