Water-repellent and more: coating textiles sustainably with chitosan

Biomolecules from renewable raw materials for the textile industry

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners in the HydroFichi project have researched how this can be done: A technology has been developed to provide fibers with the desired properties using biotechnological processes and chitosan.
