DuPont TM has been defining the fibre industry for more than 50 years with the discovery and commercialisation of well known fibres such as nylon, rayon and spandex. With the introduction of Sorona® DuPont has commercialised the most advanced polymer platform in over six decades.
Sorona® is made partially with agricultural feedstocks instead of petrochemicals, reducing our dependency on oil. In addition to fibres and fabrics, Sorona® can be used in films, filaments, engineering resins and other applications.
The only high performance fibre made with renewable resources. DuPont™ Sorona® polymer provides a unique combination of benefits to a wide variety of applications. This advanced, value-added polymer represents a major new mix-enrichment offering, with the potential for growing into a significant market over the next ten to twenty years.
DuPont™ Sorona® polymer is a unique polymer based on 1,3 propanediol (PDO). Its beneficial properties are derived from a unique, semi-crystalline molecular structure featuring a pronounced "kink", in the chain, unlike "flat" typical polymer chains. Sorona® polymer is a fibre-grade, which means it has a uniform micro-structure and a high molecular weight that enhances processing. It can be spun into fibre or made into fabric in many existing facilities that now process PET. Because Sorona® polymer is manufactured in a continuous process; the variation of polymer properties is limited. As a result, processing problems and waste generation are minimized, leading to increased productivity.
*Sorona® contains 37% renewably sourced ingredients by weight
