Sorona is DuPont de Nemours, Inc.'s brand of Triexta, a subclass of polytrimethylene terephthalate (PTT)[1] named and commercialized in 2000.[2] The fibers are soft and stain-resistant while exhibiting high strength and stiffness.[3]
Sorona is a co-polymer of
1,3-propanediol (obtained by fermentation) and petroleum-derived terephthalic acid (TPA) or dimethyl terephthalate (DMT).[3] Related polymers in this series include polyethylene terephthalate (2GT) and polybutylene terephthalate (polytetramethylene terephthalate) (4GT).[4]
Sorona can theoretically be produced from about 37% renewable resources as Presidential Green Chemistry Challenge Award for their development of the fermentation process for the production of 1,3-propanediol from corn-derived glucose in recombinant Escherichia coli K-12.[5]
The polymer Sorona has been mentioned by
industrial biotechnology. He was quoted as saying, "DuPont argues that Sorona is going to be the first billion-dollar biotech product other than a pharmaceutical".[6]
Uses and Applications
Sorona has been used in the manufacture of
carpets, automotive fabrics, and plastic parts.[7]
Mohawk Industries is currently the exclusive North American carpet manufacturer making carpets using DuPont Sorona fiber.[8]
