Sorona enables spinning mills and designers to develop both sustainable and versatile solutions. The Sorona fibre contains 37% annually renewable plant-based ingredients, i.e. corn and corn starch.

Its life cycle assessment shows that the manufacture of Sorona requires 30% less energy and releases 63% fewer greenhouse gases than the production of polyamide 6. In comparison with polyamide 6.6, Sorona consumes 40% less energy and reduces greenhouse emissions by 56%.

Sorona is used in carpets for private living spaces and commercial properties, apparel/fabrics and carpets for automotive interiors.
