Dupont Sorona Teams With Tearfil to Develop Sustainable Staple Yarns

Dupont Sorona and Portuguese spinning mill Tearfil are collaborating to develop sustainable and high-performing staple yarns for the apparel industry.

Tearfil is committed to creating smarter, cleaner and more sustainable yarns, and said choosing Sorona was a natural solution for the spinning mill. Sorona is made up of 37 percent renewable plant-based ingredients, offering a sustainable alternative to traditionally non-recyclable materials. Sorona has been adopted by brands such as The North Face, Helly Hansen and Stella McCartney.

“We believe collaboration is the key ingredient to creating the best products,” Maria de Belém Machado, CEO at Tearfil, said. “We recognize that our magic is only possible thanks to our trusted fiber and technology partners. Sustainability or performance–why not have it all? Through working with the Sorona team, we prove how future-oriented high-performance textiles can also be eco-friendly and eco-conscious.”

Sorona features many performance attributes, including softness, stretch, shape recovery, flexibility, ease-of-care and stain-resistance without the need for topical treatments. It is used in a variety of apparel, from flexible yoga wear to denim.

The Sorona fiber turns a formerly chemically based process into a biological one, using less energy and releasing fewer greenhouse gas emissions than traditional synthetic fibers. Sorona, a member of the Textile Exchange, The Sustainable Apparel Coalition and the Ellen McArthur Foundation, is a USDA-certified bio-based product and received Oeko-Tex Standard 100 Certification.

DuPont Biomaterials brings innovations to global partners through the development of high-performance, renewable materials. Its bio-based materials serve industries from packaging, food and cosmetics to apparel and carpeting, all facing the challenge of offering high performance, sustainable choices to their downstream customers.

Tearfil is a spinning mill rooted in Portugal since 1973. It offers a portfolio of yarn compositions and types in its facilities, including ring spun, open end, siro spun, vortex/air jet, injected, multi colored, melange, flamé and jaspé yarns.
