羊毛角蛋白/PVA再生纤维静电纺丝影响因素

Electrostatic spinning factors of wool keratin/PVA regenerated fibers

以废旧毛/涤混纺面料为原料,采用还原C法提取出角蛋白,将其与聚乙烯醇(PVA)共混,用静电纺丝法制备出再生化纤维;通过场发射扫描电镜观察与分析,研究接收距离和推进压力对纺丝效果的影响。结果表明:随着接收距离增大,所纺纤维直径变细;推进压力增大,所纺纤维直径明显增大,若推进压力过大,纤维出现弯曲并且直径增大;确定出了最佳接收距离为14 cm,推进压力为0.4 MPa。

In order to study the electrostatic spinning factors of wool keratin / PVA regenerated fibers,using waste wool-polyester blended fabrics as raw materials,the wool keratin is extracted by reduction C method. The wool keratin and PVA are blended and the wool keratin / PVA regenerated fibers are made by electrostatic spinning. The impacts of receiving distance and boost pressure on spinning effect are studied by SEM observation and analysis. The results show： the diameter spun fibers becomes thinner with the increasing of receiving distance; with the increasing of boost pressure,the diameter of spun fibers increases significantly; if the boost pressure is too large,the fiber diameter increases and appears bent;the optimum receiving distance is 14 cm and boost pressure is 0. 4 MPa.
