Freudenberg gets certified for biodegradability of textile

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.

Biodegradability describes the decomposition of organic materials under the effect of water, air, and microorganisms in the soil. This determines how long the process of rotting down takes and whether any substances are released during the decomposition that are hazardous for plants or animals.

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.

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. It has been certified as biodegradable and is best used with light outer materials, according to a press release.

Prof. Dr Dirk Höfer of the Hohenstein Institute said, “As part of the sustainability profile of a product, manufacturers should not only know about the manufacturing process - they also need to know which components of the product remain in the environment after it has reached the end of its useful life. It's the environmental impact that we are interested in.”

The test procedure for certification is suitable for many textile products and components, including fibres and yarns, clothing, soft furnishings, geo- or functional textiles and nonwovens. The test uses standardised soil in which there is microbiological activity, so that it realistically analyses the way materials rot in the ground.

The Hohenstein Institute test is particularly suitable for manufacturers, finishers and retailers of yarns, fibres, textile fabric, clothing and agricultural textiles, and producers of technical textiles. (GK)
