Fur is often used to create static electricity : Glass. The glass on your TV screen gets charged and collects dust : Moderate (+) charges: Human hair "Flyaway hair" is a good example of having a moderate positive (+) charge : Nylon : Wool : Lead.

The flowing movement of flammable liquids like gasoline inside a pipe can build up static electricity. Non-polar liquids such as gasoline, toluene, xylene, diesel, kerosene and light crude oils exhibit significant ability for charge accumulation and charge retention during high velocity flow.
