PVA纤维静电纺丝工艺参数研究及正交设计优化

Orthogonal optimization of electrospinning processing parameters of PVA fibres

采用静电纺丝法制备聚乙烯醇(PVA)超细纤维膜,利用扫描电子显微镜(SEM)观察溶液浓度、纺丝电压、纺丝距离对纤维微观形貌的影响,并采用正交设计对纺丝工艺参数进行优化。实验结果表明:纺丝电压是影响纤维平均直径的最重要的参数。经过优化,纺制出最小直径为0.27μm的PVA超细纤维。

Polyvinyl alcohol（ PVA） ultrafine fibre was prepared by electrospinning. The influences of the preparation solution concentration,electrospinning voltage and electrospinning（ collected） distance on the micro morphology of PVA fibre were observed by scanning electron microscope（ SEM）.The orthogonal testing analytical method was applied to optimize the processing parameters of electrospinning. The results show that the electrospinning voltage is the main impact factor of the average diameter of PVA fibres. Through optimization,the PVA ultrafine fibre with a minimum average diameter of 0. 27 um was fabricated.
