High-performance insulation, fabric and yarn specialist Primaloft has developed its first insulation made entirely from recycled PET bottles, with outdoor specialist Vaude one of the first to adopt the new innovation.

The insulation is made exclusively from post-consumer recycled (PCR) content, which PrimaLoft says fully meets all of its performance standards.

PrimaLoft Silver Insulation (100% PCR) and PrimaLoft Black Insulation (100% PCR) will be shown alongside the company's PrimaLoft Gold Insulation Luxe at this year's OutDoor Show in Friedrichshafen from 17-20 June.

"With the new 100% PCR insulation, we offer our customers the perfect product that combines performance, comfort and sustainability," says Jochen Lagemann, managing director PrimaLoft Europe and Asia. "The response from our brand partners has been overwhelming so far. This innovation is also another important step towards achieving our own sustainability goals."

By 2020, PrimaLoft plans to produce 90% of its insulation products with at least 50% recycled fibre. Most recently, the ingredient brand has provided its pinnacle products, PrimaLoft Gold Insulation and PrimaLoft Gold Insulation Active +, with 55% recycled content.

The latest developments are the result of intensive research into the production of high-performance insulation made entirely from recycled material. The challenge, the company says, is that the melting points of the collected PET bottles used to create the recycled fibres differ from that of virgin fibres, which makes the production of a stable insulation fibre that meets performance standards very difficult.

PrimaLoft says it developed special recycling and production processes, resulting in the successful production of extremely high-performance fibres that are finer and softer than cashmere and boast high bulk density and unmatched thermal performance. The insulation keeps its low weight, high compressibility and water-repellent characteristics.

Around nine commercially available PET bottles are necessary to create the insulation layer for one jacket (thickness 40g/m2).

Outdoor specialist Vaude is one of the first companies to use the sustainable synthetic insulation in its products. Starting in the winter season 2018/19, Vaude will convert all products previously made with PrimaLoft Silver and Black Insulation to the 100% PCR versions by summer 2019.

"One of our key goals is to reduce the use of fossil fuels in our products and create closed circuits," says Aaron Bittner, head of apparel at Vaude. "PrimaLoft provides us with innovative solutions on this path 'away from the oil'."
