German researchers to use insects to produce fabrics

German researchers based at the Fraunhofer Institute for Interfacial Engineering and Biotechnology in Stuttgart are exploring ways of using chitosan, derived from a component of insect skin called chitin, to replace toxic chemicals in the production of textiles.

Chitin has two potential applications in the textile industry. First, it can be used to protect textiles from breaking in the weaving process. It can be used to produce textiles with specific properties such as water resistance.

The chitosan molecule can be modified to give any fabric different properties. For example, water-resistant molecules can be added to chitosan to make textiles water-repellent.

Additionally, coating fabrics with chitosan can give them antibacterial properties. Furthermore, chitin could provide a more sustainable alternative to compounds that are currently used in the textile industry, as insects are increasingly utilized as a source of protein in the animal feed industry.
