GS Biomats serves as a plant-based alternative to the traditional fossil-based fibers.
PEF fiber is a next-generation, bio-based polyester fiber derived from FDCA, designed for apparel, technical textiles, interior fabrics, flooring and automotive uses — enhancing comfort, durability and functional performance while opening new design possibilities. As a sustainable textile, Furan Biobased fibers (notably PEF-derived fibers) are available as filaments, staple fibers and more, and blend seamlessly with natural fibers like cotton, wool and lyocell as well as common synthetics.

PEF is derived from renewable biomass feedstocks and delivers intrinsic antilbacterial, antiviral activity (HPV16: 96.92%), UV-resistant and anti-mite performance without chemical additives.
PEF delivers a 43.8% reduction in carbon footprint compared to PET, it’s production also avoids harmful additives, enhancing safety andenvironmental compliance.
Yes. As a sustainable textile material, PEF can be blended or interwoven with natural fibers such as cotton, wool, and lyocell, as well as synthetic fibers like PET and nylon. Blending enhances comfort, functionality, and fabric versatility.
PEF bio-based fibers are positioned for high-growth markets demanding sustainable and functional textile materials. With ongoing R&D, applications in technical textiles, advanced composites, and high-performance fabrics will continue to expand.
PEF fibers can be spun, woven, knitted, or blended to create a wide range of textile and industrial products:
Apparel & fashion textiles
Functional & performance textiles
Home textiles
Industrial yarns & technical fibers
Fiber blends & hybrid yarns
