Lignin coating makes Geotextiles made from environmentally friendly natural fibers durable
Textiles are a given in civil engineering. Until now, textiles made of resistant synthetic fibers have been used for this purpose, having a long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade when it has done its job. Natural fibers, in contrast, often decompose too quickly. The DITF are developing a bio-based protective coating that extends their service life.
