Freudenberg Interlining, market leader for nonwoven products, is the first German company to get certification for the biological degradability of a textile product, by the Hohenstein Institute in Bonnigheim. Freudenberg developed a nonwoven textile made of special polyester fibres which can be used as a lining to strengthen items of clothing or parts of garments. The Hohenstein Institute’s test system assesses the degradation of organic substances by microorganisms, water, and oxygen in realistic conditions in the soil. It is based on standardised soil burial tests according to international norms. A product is endorsed after a sample has decomposed and its ecotoxicological safety has been confirmed.
