Duke University students have put Nano-Tex nanotechnology
fabrics to the test by attempting to stain samples of the cloth with
coffee. The simple test was remarkable as they have posted a video
documentation of their test on YouTube.
The video shows the students first attempting to stain the
pouring coffee on the stain from a pipette. This is completely
unsuccessful so the students completely immerse the fabric sample in
the coffee. It comes out damp but the coffee ismerely on the surface of
the sample and is easily wiped off. A control sample of normal
material, is immediately wet and stained upon contact with the coffee.
