Polartec Power Shield Debuts Bio-Based Weather Tech

Polartec, a Milliken & Company brand, has launched a bio-based Polartec Power Shield fabric technology it said sets a new standard for sustainable weather protection.

The debut signifies Polartec’s continued pivot to source living matter substitutes for petroleum-based products, while increasing the efficiency and performance of fabrics and materials. The advanced monolithic membrane of Polartec Power Shield is made from a combination of plant-based and non-PFAS materials, and achieves a combination of waterproofness, windproofness, long-lasting breathability, high durability and comfortable stretch.

Constructed for a range of solutions, Polartec Power Shield is the most capable and versatile waterproof breathable technology developed in the company’s fabric portfolio. It’s also the latest addition to the company’s complete conversion to non-PFAS alternatives across its entire range of fabrics.

“With the launch of Power Shield, we’re reinforcing Polartec’s expanded capabilities of breathable and waterproof solutions–from expedition grade durability to fashion-forward hand and drape, while also pioneering the use of bio content to achieve these remarkable functionalities,” Polartec president Steve Layton said. “We’re proud to launch a proprietary solution constructed from all non-PFAS polymers and plant-based building blocks that do not compete with human food sources. It is our commitment to reduce reliance on petroleum, while producing a membrane that offers greater water-resistance performance than we’ve ever brought to market.”

Ramesh Kesh, senior vice president of research, sustainability and textile development at Milliken, said at the center of Polartec Power Shield’s functionality is a major advancement in membrane technology.

“The highly durable monolithic membrane is a barrier specifically engineered to be impermeable to outside weather, while transporting moisture vapor from skin-to-surface via molecular diffusion,” Kesh said.

The end result is Polartec’s first waterproof fabric to test greater than 20,000 millimeters in the Hydrostatic Pressure Test for waterproofness and a 20,000 grams per square meters per day  Moisture Vapor Transmission Rating for breathability. The advancement and versatility pairs with a wide range of fabrics–from supple stretch and bombproof wovens to low-snag and high-stretch knits. The all-new Polartec Power Shield brings a soft hand and tough barrier to outside rain and snow that is incorruptible over time.

Polartec Power Shield is available now to manufacturers and makers in six variations of face and backing fabrics in knits and wovens, and will debut in market-ready products offering a range of capabilities from city to summit use beginning Fall 2023.
