STEPS
-
I. Wool pre-treatment
We use acetone or ethanol to clean all dirty parts of wool fleece and remove first layers of wool fiber (cortex & cuticle) and lanolin. Then we are able to more easily open the fiber bonds.
-
II. Chemical dissolution
The wool fiber will disappear in chemical solution with urea and NaOH. That means its additional layers of wool fiber will be destroyed. You will achieve a liquid yellow/brown solution which you will need to clean. Keratin is now still mixed with the rest of the chemicals.
-
III. Filtration & Centrifugation
Filter and purify the extracted solution. Centrifugation serves as a tool to separate chemical molecules from molecules of wool protein. The DIY centrifuge is made of an electric drill and 3D printed parts.
-
IV. Biuret test
Protein presence test with home-made Rochelle crystals.
-
V. Dialysis
Instead of cellulosic dialysis tubes we will use a cow stomach to filtrate the extracted solution from the rest of the chemicals.
-
VI. Freeze-drying

ELECTRO-SPINNING
Electro-spinning machine is designed to produce nano or micro scaled fibers. The syringe with the solution inside is connected by a needle to a high voltage generator and is able to spin or spray the material onto a metal collector. It creates a soft surface on aluminum foil.
TEXTILE COATING
A thin, almost insivisible layer of textiles and layer with waterproof and flame-retardant properties can be achieved using spray textiles coating.
This type of coating was texted with pure keratin powder or in combination with alginate to create a protective layer of textiles or biomaterials intead of chemical treatments.
DIY TOOLS
A centrifuge is a laboratory device that is used for the separation of fluids, gas or liquid, based on density. Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force pushes heavier materials to the outside of the vessel.
