首先，研究了纺丝温度、纺丝电压、集电极间距和环境温度对熔融电纺PP纤维直径的影响。结果表明，随着纺丝温度、纺丝电压和集电极间距的增加，纤维直径先减小后增大。但随着环境温度的升高，纤维直径逐渐增大。其次，在前人研究结果的基础上，利用响应面方法研究了工艺参数对纤维直径的综合影响，建立了预测纤维直径的二次多项式方程。结果表明，4个因素对纤维直径的影响大小顺序为纺丝温度>>集束距>>环境温度>>纺丝电压。此外，响应面分析预测的纤维直径与实验结果吻合较好。最后，将不同纤维直径的三层熔融电纺PP网与常规非织造布进行在线复合
Firstly, the effects of the spinning temperature, spinning voltage, tip-to-collector distance and ambient temperature on the diameter of melt-electrospinning polypropylene (PP) fibers were studied. The results showed that with the increase of the spinning temperature, spinning voltage and tip-to-collector distance, the fiber diameters first decreased and then increased. However, when the ambient temperature increased, the fiber diameters increased gradually. Secondly, based on the previous results, the response surface methodology (RSM) was used to investigate the combined effects of processing parameters on fiber diameters and establish a second-order polynomial equation to predict the fiber diameter. The results showed that the effect order of four factors on fiber diameter was as follows: spinning temperature > tip-to-collector distance > ambient temperature > spinning voltage. Moreover, the fiber diameter predicted by response surface analysis fitted well with the experimental result. Finally, three layer melt-electrospinning PP webs with different fiber diameters were online compounded with conventional non
