Hohenstein claims first in ecotoxicity of fibres test
Germany-based testing institute Hohenstein has developed a test to measure biodegradability and ecotoxicity of textile fibres in soil.
DIN SPEC 19296 focuses on textile products and the fragments released through use, abrasion or disposal. Tests are conducted in standardised soil under defined climatic conditions over a period of up to 180 days.
The method combines a respirometer system that measures the oxygen consumption of microorganisms during degradation, plant growth tests using cress seeds to assess potential effects on vegetation, and earthworms are used as bioindicators to evaluate possible toxic effects.
Juliane Alberts, project manager at Hohenstein, said: “It makes an invisible issue visible and supports the development of more sustainable textile products.”
