Sorona

Sorona is DuPont's brand of triexta (polytrimethylene terephthalate).[1] It was named and commercialized in 2000.[2] The fibers are claimed to be both soft and extremely 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]
The polymer Sorona has been mentioned by J. Craig Venter in interviews[5] as an example of an application of 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." The renewable resource content of SORONA is 37% by weight.[3] DuPont won a 2003 Presidential Green Chemistry Challenge Award for their development of the fermentation process for production of 1,3-propanediol from corn-derived glucose in recombinant Escherichia coli K-12.[6]
DuPont's CEO (Ellen J. Kullman) has worn a pinstripe suit made of Sorona fibers[7]
Uses and Applications
Sorona has been used in the manufacture of clothing, residential carpets, and automotive fabrics and plastic parts.[8] Mohawk Industries is currently the exclusive carpet manufacturer currently making carpets using Dupont Sorona fiber.[9][10]
