Work Step by Step
When 2 different materials are rubbed together, as in a dryer, they can transfer electrons (see “triboelectric effect”), and one becomes positively charged while the other becomes negatively charged. The opposite charges cause the objects to cling together.
Some materials lose electrons more readily than others. If all of your clothes were of the same material, on average, they would have the same affinity for electrons and exchange very little charge, resulting in less static cling.
