Abstract

Wet spinning of nanocellulose in purely aqueous systems for functionalized filament formation represents a significant yet challenging research frontier. This study develops a sustainable wet-spinning approach to produce high-performance macrofibers using TEMPO-oxidized bacterial cellulose nanofibers (TOBCN), sodium alginate (Alg), and metal-phenolic networks (MPNs). The system utilizes Fe³⁺-mediated cross-linking in MPNs combined with Ca²⁺-induced ionic bonding with TOBCN to achieve enhanced mechanical properties. The optimized Alg/TAFe₁-TOBC₂ fiber demonstrates remarkable multifunctional characteristics, including photothermal antibacterial efficacy exceeding 99% against both Escherichia coli and Staphylococcus aureus, superior flame retardancy with 61.05% lower heat release compared to cotton, and excellent UV protection with UV protection factor values surpassing 100, which exceed standard textile requirements. The purely aqueous processing and biomass-based composition ensure environmental compatibility and biocompatibility. These macrofibers hold promise for protective textiles, combining sustainability with high performance.

湿纺多功能大纤维：利用多网络纤维素基水性胶体整合抗菌、阻燃和紫外线屏蔽性能。

在纯水体系中湿纺纳米纤维素用于功能化长丝的形成是一个重要但具有挑战性的研究前沿。本研究开发了一种可持续的湿纺丝方法，利用tempo氧化细菌纤维素纳米纤维（tobn）、海藻酸钠（Alg）和金属酚网络（mpn）生产高性能大纤维。该系统利用Fe3+介导的mpn交联，结合Ca2+诱导的与tocn的离子键来实现增强的机械性能。优化后的Alg/ tafe1 - toc2纤维具有显著的多功能特性，对大肠杆菌和金黄色葡萄球菌的光热抑菌效果均超过99%，阻燃性能优越，放热比棉低61.05%，防紫外线性能优异，紫外线防护系数超过100，超过纺织品标准要求。纯水处理和生物质成分确保了环境相容性和生物相容性。这些大纤维有望成为保护性纺织品，将可持续性与高性能相结合。
