Biomass materials show broad application prospects in many fields. Bio-based PTT fiber become the new hot spot for its excellent performance

environmental protection and sustainable development. In the paper

the research and production profile of 1

3-PDO at home and abroad are systematically introduced

and the energy advantages and technical bottlenecks of microbiological method are indicated. The research progress in aspects of bio-based PTT fiber preparation

structure and properties has been reviewed. Besides

the favorable situation to develop bio-based fibers and products is also illustrated. As biological 1

3-PDO technology is improving

the raw material cost

long hindered the development of PTT fiber

can be further reduced. It is well worth looking forward to rapidly develop bio-based PTT fiber.
