Description

DuPont™ Sorona® is a chemical fibre based on polytrimethylene terephthalate (PTT), obtained to about 37 % from renewable raw materials — in particular plant-fermented 1,3-propanediol from corn. It has been produced by DuPont™ (today Covation Biomaterials) since 2000.

The fibre combines several properties that would normally require blends: inherent stretch without elastane, soft hand, deep colours, good stain resistance and quick drying. It is often labelled with the bio-PDO share or under specific sub-brands (Sorona® Aura, Sorona® Cardura).

  • Partly plant-based (bio-PDO from corn)
  • Inherent stretch without elastane
  • Soft, colour-rich, stain resistant
  • Lower CO2 footprint than conventional PES

Sorona® is used in outdoor, sports and fashion collections as well as in carpets and automotive interiors.
