成果介绍

本发明实施例提供一种防雾霾无纺布的制备方法，涉及无纺布制备技术领域。该方法包括：选取包含甜菜碱基团的两性离子聚氨酯为原料，将原料分别配置成质量分数为15～35％和3％～10％的第一溶液和第二溶液，利用静电纺丝技术将第一溶液纺丝制备直径为1.0～2.0μm的无纺布支架，并在无纺布支架上对第二溶液纺丝得到200nm～500nm的纳米纤维，使得无纺布支架和纳米纤维相互交错形成包含大量孔隙结构的所述防雾霾无纺布，其中，纳米纤维和作为无纺布支架的纤维的数量比为19 : 1～19。由于第一溶液纺丝制备的纤维较粗，可以提高无纺布的力学性能。另外，甜菜碱基团具有良好的抑菌作用，可以防止雾霾中细菌的传播。
