The amalgamation of sustainable practises throughout the fabrication process with advanced material engineering holds promise not only for eco-conscious manufacturing but also for promoting technological advancements in versatile material design and application. Moreover, technological innovation serves as a catalyst for sustainability initiatives, driving innovation and enabling the adoption of greener practises across industries. This study investigates redefining the production protocol of pressure spinning to produce core-sheath polymer fibres, deepening sustainable practises. It aims to explore innovative approaches such as modifying spinning parameters, optimising polymer solvent configurations and understanding fluid behaviour to curtail material wastage and maintain minimal energy consumption without compromising production efficiency. Utilising Polyvinylpyrrolidone (PVP) for the core and Polyethylene oxide (PEO) for the sheath, production rates of up to 64 g/h were achieved with a fibre diameter range of 3.2 ± 1.7 µm to 4.6 ± 2.0 µm. Energy consumption per mass of fibres produced showed a decreasing trend overall with increasing applied gas pressure. These findings highlight the potential for the efficient and scalable production of core-sheath fibres with applications in various advanced materials fields.
在制造过程中将可持续实践与先进材料工程相结合，不仅对注重环保的制造业有前景，而且对推动多功能材料设计和应用的技术进步也有前景。此外，技术创新是可持续发展倡议的催化剂，推动创新并促使各行业采用更环保的做法。本研究调查重新定义压力纺丝的生产方案以生产核壳聚合物纤维，深化可持续实践。其旨在探索创新方法，如改变纺丝参数、优化聚合物溶剂配置以及理解流体行为，以减少材料浪费并在不影响生产效率的情况下保持最低能耗。以聚乙烯吡咯烷酮（PVP）为芯、聚环氧乙烷（PEO）为鞘，实现了高达64克/小时的生产率，纤维直径范围为3.2±1.7微米至4.6±2.0微米。每生产单位质量纤维的能耗总体上随着施加气压的增加呈下降趋势。这些发现突出了高效且可扩展地生产核壳纤维在各种先进材料领域应用的潜力。
