Bioextrax has just submitted a patent application for the process of producing fibers from feather.
The micro fibres are first-of-its-kind and can only be produced with the Bioextrax bioabased method. Their small size (30-200 microns) means a lot of surface area. The fibres further have a hollow-cylindric structure (meaning low density and good insulation properties). The material has high thermo-stability, is water insoluble, biobased and biodegradable.
Bioextrax is in the process of exploring application to this new material – please get in touch if you have any ideas!
