
Coated fibers with Titanium Dioxide
nanocrystals(TiO2)
Materials wool, silk, and hemp are
coated with TiO2
They will break down food and dirt in
sunlight
Examples: food, grime and even red
wine
How it works?




The fibers in the materials have
Keratin witch don’t attract any groups.
They add carboxylic group to attract
the TiO2.
Then dip the material in TiO2
Now the material will decompose food
and dirt with sunlight. But is harmless
to us and the material
TiO2

Without TiO2

Hemp with TiO2
