Tearfil, the Portuguese specialist in textile yarns, will use Sorona fibers to develop sustainable and high-performing staple yarns for the apparel industry. Sorona is made up of 37 percent renewable plant-based ingredients. Compared with Nylon 6, Sorona uses 30 percent less energy, and releases 63 percent less greenhouse gas, according to DuPont.

Sorona is a member of Textile Exchange, Sustainable Apparel Coalition, Sustainable Brands and the Ellen McArthur Foundation, as well as a bluesign® system partner. The Sorona fiber has also been approved by the United States Department of Agriculture (USDA) as part of USDA’s BioPreferred Program for certified bio-based products, and has earned Class ll certification by Oeko-Tex’s Standard 100.

Tearfil, based in Moreira de Cónegos, Portugal, was founded in 1973. In 2011, the company was acquired by the Moretextile group but since 2019, Tearfil has been working independently again under the management of Maria de Belém Machado, a private investor with a family history in the spinning business.
