Abstract

Vortex airflow-assisted melt differential electrospinning for preparing superfine fiber yarns was proposed. This method with solvent-free exhibits a higher yield of 20 ± 5.17 m/min compared to the range of 0–5 m/min achieved by solution electrospinning with organic solvents. Simulation and high-speed photography show that the fibers are aggregated by suction airflow and twisted into yarns by vortex airflow. Polylactic acid (PLA) superfine fiber yarns exhibit fine fiber diameters ranging from 0.96 to 5.57 μm, a yarn diameter of 211.7 ± 40.8 μm, and a high tensile strength of 39.4 ± 3.12 MPa. Furthermore, these PLA melt electrospun yarns can be woven into fabric with a water contact angle of 120.1° and triboelectric voltage of 7.41 V, demonstrating their potential in self-cleaning textiles and flexible smart textiles. Moreover, this method is generally applicable to thermoplastic polymers including polyethylene terephthalate (PET), polypropylene (PP), and polycaprolactone (PCL). It provides a promising approach for green industrialization of superfine fiber yarns.

涡旋气流辅助熔融差动静电纺丝绿色高效制备超细纤维纱线

提出了旋涡气流辅助熔融差动静电纺丝制备超细纤维纱线的方法。与有机溶剂溶液静电纺丝的收率为0 ~ 5 m/min相比，无溶剂溶液静电纺丝的收率为20±5.17 m/min。模拟和高速摄影表明，纤维在吸力气流作用下聚集，在旋涡气流作用下捻成纱。聚乳酸（PLA）超细纤维纱线的细纤维直径范围为0.96 ~ 5.57 μm，纱线直径为211.7±40.8 μm，抗拉强度为39.4±3.12 MPa。此外，这些PLA熔融电纺丝可以织造成水接触角为120.1°、摩擦电压为7.41 V的织物，展示了它们在自清洁纺织品和柔性智能纺织品方面的潜力。此外，该方法一般适用于热塑性聚合物，包括聚对苯二甲酸乙二醇酯（PET）、聚丙烯（PP）和聚己内酯（PCL）。为超细纤维纱线的绿色产业化提供了一条有前景的途径。
