Abstract
本发明公开了一种静电纺PET / 熔喷PP无纺布复合生产方法，该生产方法包括以下步骤：步骤一，取熔喷PP无纺布，在熔喷PP无纺布表面喷涂结合液，接着烘干；步骤二，PET用有机溶剂溶解配成透明的纺丝溶液，取纺丝溶液，在熔喷PP无纺布上纺丝，控制纺丝时间为20‑30min；结合液由以下质量百分比的组分组成：聚乙烯醇40‑60%、硅藻土0.5‑1%、丙烯酸‑2‑丙烯酰胺‑2‑甲基丙磺酸共聚物5‑10%、脂肪醇聚氧乙烯醚1‑2份%、EDTA二钠0.1‑0.3%、混合溶剂33.4‑46.7份。本申请中静电纺丝形成PET膜能稳定地复合在熔喷PP无纺布表面，且复合后的复合纤维保持较佳的过滤效果。
