Hohenstein evaluates environmental suitability of textiles

Like all organic materials, textiles will decompose under the influence of water and microorganisms in the ground. Under comparable environmental conditions, it depends mainly on the raw materials used whether the decomposition process takes place over the course of months, years, decades or even centuries.

In combination with any added chemical finishes these are also a crucial factor for the decomposition potentially generating individual substances or substance combinations which may be harmful to flora and fauna.

Raw materials (fibre types) and additional finishes are some of the factors the scientists at the Hohenstein Institute in Bönnigheim/Germany take into account when evaluating the effects of textiles on the environment.

In addition to textile manufacturers, it is increasingly the producers of prefabricated automotive parts, the chemical industry and recycling companies who obtain advice from the team of Prof Dr Dirk Höfer who will create an individual test plan for the neutral evaluation of the ecological harmlessness of products.

As a rule, the evaluations are based on standardised soil burial tests according to international standards which are used to determine the decomposition or breakdown behaviour of materials. Subsequent ecotoxicological examinations allow the scientists to draw conclusions about the environmental compatibility in the sense of risk monitoring.

In contrast to classical analysis methods, this method does not focus on verifying the presence of individual substances with known ecological hazards. It is rather a consideration of influence of the sum of all individual substances and substance combinations on biological systems. The method uses marine bacteria, water fleas and fish eggs, among other things.

Regardless of the field of use of the (textile) materials, the requirements concerning decomposition in the ground can vary greatly in some cases: For everyday products such as clothing or home furnishings, decomposition e.g. in landfill should take place as quickly as possible and without any residues which could be harmful to health or environment.

The same applies to geotextiles where composition should take place as quickly as possible while generating valuable humus to promote natural growth of plants. In contrast to this, other technical textiles and geotextiles are treated with chemical substances to make them more resistant to microorganisms such as mould.

The aim here is to optimise the durability of reinforcements for embankments, dykes etc. where these textiles are used. The Hohenstein experts are studying how to meet the requirements of both objectives. Established methods such as standardised soil burial tests in combination with laboratory tests offer an interesting alternative to extensive outdoor tests in terms of time and cost involved.
