Abstract: 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.

Key words: bio-based synthetic fibers; chemical fibers; bio-based monomer
