A high-molecular-weight aromatic polyamide resin incorporating furan-rings (f-resin) was prepared by low-temperature solution polycondensation of bio-based 2,5-furandiformyl chloride and 3,4′-diaminodiphenyl ether, in N,N-dimethylacetamide. Further, an aromatic polyamide fibre containing furan-rings (f-fibre) was obtained from the fresin by dry-jet wet spinning, and its structure and properties were investigated. The prepared f-resin showed good solubility and possessed good spinnability in solution. The mechanical, heat-resistance, and flame-retardant properties of the f-fibre were found to be excellent – comparable to or exceeding those of meta-aramid fibre (m-fibre). In addition, the furan acid chloride monomer is bio-based and is derived from abundant resources, unlike petroleum-based monomers. Therefore, f-fibre has good potential and broad application prospects as an environment-friendly and sustainable high-performance material.

通过生物基 2,5-呋喃二甲酰氯和 3,4'-二氨基二苯醚在 N,N- 中的低温溶液缩聚反应制备了含有呋喃环的高分子量芳族聚酰胺树脂（f-树脂）。二甲基乙酰胺。此外，通过干喷湿纺从树脂中获得了含有呋喃环的芳族聚酰胺纤维（f-纤维），并研究了其结构和性能。制备的氟树脂在溶液中具有良好的溶解性和良好的可纺性。发现 f 纤维的机械、耐热性和阻燃性能非常出色——可与间位芳纶纤维（m 纤维）相媲美或超过这些性能。此外，呋喃酰氯单体是生物基的，资源丰富，与石油基单体不同。所以，
