生物基合成纤维单体发展现状及展望

近年来,开发环境友好、性能优良的生物基合成纤维已经成为未来化学纤维领域发展的重要方向,但制约我国生物基合成纤维发展的主要瓶颈是上游生物基单体原料的制备及规模化生产技术。文章综述了国内外生物基合成纤维单体的发展现状,如PTT单体1,3-丙二醇、PLA单体乳酸、PBS单体1,4-丁二酸、PA56单体1,5-戊二胺等,并对我国生物基纤维单体开发与应用提出了相应的建议。

Development and Outlook of Bio-based Synthetic Fiber Monomers

In recent years, developing environmental-friendly and high-performance bio-based synthetic fibers has become an important development direction of chemical fiber industry However, the preparation and large-scale production technology of monomer is the main bottleneck in the development of bio-based synthetic fibers in China. In this paper, the development status-quo of bio-based synthetic fiber monomers, such as PTT monomer 1,3-propanediol, PLA monomer lactic acid, PBS monomer 1,4-succinic acid, PA56 monomer1,5-pentamethylenediamine, etc., at home and abroad was reviewed, and relevant suggestions on the development and application of bio-based fiber monomers were put forward.
