Polartec introduces performance fabrics made with Biolon™Polartec has upgraded products from two of the performance fabric platforms that use its Biolon plant-based nylon fibre and membrane technology. Biolon is described as a renewable, non-GMO plant-based nylon with a 50% lower carbon footprint than virgin Nylon 6,6. Biolon nylon properties – durability, comfort and breathability – are said to be closer to nylon 6,6 than many recycled nylon alternatives currently on the market.
