Current Status of Bio-based Synthetic Fiber Technologies

2026年1月21日

Abstract: Driven by global carbon reduction targets and green manufacturing policies, the synthetic fiber industry is rapidly shifting toward renewable, bio-based feedstocks. By partially or fully replacing fossilderived raw materials with biomass, bio-based synthetic fibers can significantly reduce carbon emissions while delivering performance comparable to conventional counterparts, positioning them as a key direction for textile materials. This article reviews major categories of bio-based polyester fibers, bio-based polyamide fibers, and bio-based polyurethane fibers. Specifically, it highlights representative fibers, such as biobased polyethylene terephthalate (PET), polylactic acid (PLA), bio-based poly(trimethylene terephthalate) (PTT), polyethylene furanoate (PEF), bio-based polyamide 56 (PA56), bio-based polyamide 510 (PA510), and bio-based spandex, with an emphasis on their key monomer sources, technological routes, and progress in industrialization. The review focuses on key monomer sources, synthetic pathways, and current industrialization status, aiming to provide actionable insights to advance bio-based synthetic fibers and support the green and low-carbon transformation of the textile industry.
