生物基聚酰胺56纤维在纺织领域的应用研究进展

针对我国目前高度依赖进口石油和聚酰胺66主要原料己二胺被国外公司垄断的局面,顺应我国早日实现碳中和的战略目标,在简要回顾生物基聚酰胺发展历程的基础上,对生物基聚酰胺56纤维的特性作了详细描述,对其制备技术与应用领域的研究进展进行了综述。生物基聚酰胺56纤维具有良好的力学性能、吸湿性、柔软性、耐磨性、染色性、耐热性、耐化学性与阻燃性,适合应用于服装、家纺、产业用纺织品等领域,但生物基聚酰胺56纤维大规模推广还面临生物原料供给与成本控制、生产中能耗降低及副产物综合利用等问题,今后需要继续在生物基单体发酵与纯化、聚合、纺丝及应用等领域加大研发投入,不断降低生产成本,才能促进生物基聚酰胺56纤维在纺织领域的大规模应用。

Research progress on applications of bio-based polyamide 56 fibers in textile fields

China is highly dependent on imported petroleum,and hexanediamine,the main raw material for polyamide 66,is monopolized by overseas companies.In line with the strategic goal of achieving carbon neutralization in China,this paper describes the characteristics of bio-based polyamide 56 fiber in detail,and reviews the research progress in its preparation technology and application fields.Bio-based polyamide 56 fiber has good mechanical properties,moisture absorption,softness,wear resistance,dyeing,heat resistance,chemical resistance and flame retardancy,which is suitable for clothing,home textiles,industrial textiles and other textiles fields.However,the large-scale promotion of bio-based polyamide 56 fiber still faces problems such as the supply and cost control of biological raw materials,the reduction of energy consumption in production and the comprehensive utilization of by-products.In the future,it is necessary to continue to increase research and development investment in fermentation and purification of bio-based monomer,polymerization,spinning and application in order to continuously reduce production costs,so as to promote the large-scale application of bio-based polyamide 56 fiber in the textile field.
