DuPont and Unifi launch ‘eco-friendly’ insulation

US-based companies DuPont Industrial Biosciences and Unifi have collaborated on a new insulation based on their Sorona and Repreve products.

Sorona is made from 37% renewable plant-based ingredients, and is said to use 30% less energy in its production compared with nylon 6.

Repreve fibre contains recycled materials, including plastic water bottles.

“The combination of Sorona and Repreve provides brands the opportunity to use a high-performance, durable insulation that dries quickly and keeps its shape even after washing,” said Michael Saltzberg, global business director for biomaterials at DuPont. 

“The new insulation’s unique warmth and durability will bring customers streamlined outerwear, made from eco-friendly materials, while maintaining maximum warmth and breathability.”
