Dupont Sorona announces preferred mill network

Sorona, the 37% bio-based polymer offering from Dupont, has introduced its global preferred mill network as it looks to scale the availability of sustainable fabrics.

The global preferred mill network offers its full collection of sustainable Sorona sub branded fabrics— Agile, Aura, Luxe, Profile, and Revive.

The network of certified mills is available to any apparel brand in need of samples and sourcing of fabrics scientifically tested to meet the performance and sustainability standards set by the Sorona team.

“The impacts of sustainability efforts are best at scale,” says DuPont global brand and communications leader Alexa Raab. “Through the recent COP26 Climate Change Summit we’ve seen how much work there is to do in all corners of the industry. We’re taking this step with the Preferred Mill Network and Common Thread Fabric Certification Program to further our commitment to transparency and ease of access to sustainable fabrics throughout the value chain.”

Since the debut of the Common Thread Fabric Certification Program, Sorona has certified 350 fabric mills worldwide and shipped hangtags for more than 43.7m garments. Among the certified fabrics, the most certified option is Sorona Agile, the comfort stretch fabric used as a spandex replacement in activewear and athleisure garments.

To qualify for certification, fabric mills must submit fabric swatches to the DuPont (or DuPont approved) lab for testing. Each sample is rigorously analysed for a minimum content level of Sorona, as well as for quality and performance characteristics.

Certified fabric types include:

  • Sorona Agile — an alternative for any garment where spandex-free stretch is needed.
  • Sorona Aura — lightweight insulation fill with unparalleled softness, outstanding fill power, and a higher level of thermal insulation.
  • Sorona Luxe — natural fibre blends are enhanced with softness, dimensional stability, and reduced pilling.
  • Sorona Profile — a replacement for 100% nylon or PET fabrics that offers improved crease recovery and a rich, soft hand feel.
  • Sorona Revive— shape retention and dimensional stability without sagging and bagging.

Just Style reported that DuPont had launched a fabric collection made with DuPont Biomaterials Sorona in June 2021.
