Abstract：
The centrifugal spinning (CS) method could address common issues such as low production rate and high energy consumption in the industry of nonwoven textile fabrication. Similarly to cotton candy production, the high-speed rotating reservoir extrudes melt or solvent-based polymer from orifices to produce fibres. Using polymer melt avoids solvent elimination and toxicity, but the process is more difficult. Thus, a versatile lab-scale hot melt spinneret with the ability to pour pellets inside continuously to expand our knowledge of the CS method and investigating different extrusion geometries such as nozzlefree is developed. Among the controllable parameters are, the spinneret heating temperature (up to 300°C), its two interchangeable 3D printer nozzles. An Arduino code is used to stabilize the temperature. The system performance is investigated with polypropylene and polylactide. The results show that fibres under 15 μm in diameter are produced. This work is licensed under CC BY-NC 4.0.

摘要：
离心纺丝（CS）方法可以解决常见的问题，例如低生产率和高能耗的非织造纺织品制造行业。类似于棉花糖生产，高速旋转的储存器从孔口挤出熔体或溶剂基聚合物以生产纤维。使用聚合物熔体避免溶剂消除和毒性，但是这个过程更加困难。因此，开发了一种多功能的实验室规模的热熔喷丝头，能够连续倒入颗粒内部，以扩大我们对CS方法的了解，并研究不同的挤出几何形状，例如无喷嘴。在可控参数中，喷丝头加热温度（高达300°C），它的两个可互换的3D打印机喷嘴。Arduino代码用于稳定温度。用聚丙烯和聚乳酸研究了系统性能。结果表明,产生了直径小于15μm的纤维。这项工作在CCBY-NC4.0下获得许可。要查看此许可证的副本，visithttp://creativecommons.org/licenses/by-nc/4.0/。
